Now is an ideal time to prevent damage caused by Chafer Grubs

Chafer grubs are the larvae of the chafer beetle.

They can cause problems on any grassed area including lawns by feeding on the roots of grass plants.

The adults range from 9 to 39 mm in length and have different coloured heads and wings cases. The adults emerge between the end of May and July depending on the weather conditions in spring. They may feed on shrubs and trees before laying the eggs into grassed areas.

Larvae hatch about 2 weeks later and begin to feed on grass roots until late September when they move deeper into the soil where they pass the winter. The larvae have white bodies curved in letter C shape, light brown heads, with 3 pairs of legs.When the larvae are small they do not cause much damage to grass unless they are in very high numbers. As they grow bigger, they cause more damage.

Symptoms may appear as straw-coloured weak areas of grass, where the roots have been damaged. In most cases the larvae are discovered when birds or mammals, such as badgers or foxes, begin to rip up areas of the turf looking for the grubs. They are a protein filled delicacy to birds and mammals, which can destroy large areas when looking for them.

It is very difficult to prevent chafer larvae being laid into the lawn. Females prefer moist conditions and so the lawn should not be watered if adults are seen. However, where larvae are present the lawn should be kept well watered to try and counteract the grass from dying through drought due to a weaker root system. In most cases all that can be done is to employ bird and mammal deterrents and tidy up any damage caused.

The larvae can be controlled by removing them by hand or applying a biological nematode, such as Rolawn Chafer Grub Killer, which can be applied from late July until October. Rolawn Chafer Grub killer is specific to the pest concerned therefore safe for the user, children, pets, wildlife and the environment.

Caring for China Doll Plant (Radermachera sinica)

Question:

I have this extremely leggy and tall China Doll plant. The tops are taller than I am and the “bottoms” are leafless. If I cut it down will I get new growth from the bottom again or will I kill the plant.

Answer:

China Doll (Radermachera sinica) is fairly new as a house plant and can be quite fussy and difficult to grow.

It needs lots of bright light but not direct sunlight so it is best on a north or east facing windowsill. They also prefer a constant temperature of between 65 and 75 degrees away from drafts. Once you have found a place it likes leave it there as they hate to be moved around. These plants often drop their leaves for many reasons including a changes in light or temperature, irregular watering, pests and repotting. If is best to keep this plant pot bound and to prune it regularly to keep the size in check. Water regularly but don’t over water and don’t allow it to dry out completely.

The first thing you need to establish is that the stem is alive; you can do this by gently rubbing your thumbnail over the surface of the stem, if it is green underneath then it is alive, if it is brown and the stem is brittle then I’m afraid it has died. Do this test up the length of the stem to find if, and where it is dead. If it is green to the tip then all is not lost.

The next step is to cut it back to about half it’s current size, it will then begin to grow again from this point. Let it gain some height and prune it every few months to keep it healthy but to allow some slow growth.

Once this is done then follow the care rules above and it should be OK from now on.

Plant of the Month for September – Japanese Anemone

Our plant of the month for September is Japanese Anemone.

Japanese Anemone are beautiful plants, are very easy to grow and flower their heads off from August through to the frosts. During September they are at their best when there are few other plants around. The Gardening Register has two varieties in the garden Anemone ‘September Charm’ and Anemone ‘Honorine Jobert’. Honorine Jobert has been in for nearly ten years now and it never ceases to amaze me every year. September Charm was planted last autumn so this is it’s first true flowering season. The plants need to bulk up a bit before they’ll be as showy as Honorine. Take a look at the plants in our garden.

They are happy in full sun or partial shade and prefer moist, fertile soil. They are fully hardy and flower between July and September or even to the frosts if you’re lucky.

To care for your Japanese Anemones:

• Cut back the stalks after the flowers have faded
• Tidy up old dead leaves in March
• Apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or manure around the base of the plant in spring
• Avoid moving the plant since it resents disturbance
• Where necessary lift and divide congested clumps in early spring

Which growing medium should I use?

Question:
I have read in a well known gardening book that plants do not like being transplanted into a different medium. Does that include transplanting from peat based raising plant medium to garden soil?

Answer:
I must admit I don’t worry too much about the different types of growing medium. I use a good quality everyday compost and if I need it to be free draining, or for sowing seeds and planting cuttings, I add grit or vermiculite, if I need it rich I add manure, if I need it more fertile I’ll add pelleted chicken manure. When planting into the garden I add compost to the planting hole but back fill with the garden soil I’ve removed from the hole so it is not such a shock for the plant. There are only two situations in which I use the “correct” medium and that is to use ericaceous compost/soil for acid lovers and aquatic soil for planting in ponds. So far this method has not caused me any problems.

Make your own Compost

Composting can be as simple or as complex as you want to make it and the best part is that it can consist of any organic material that we all have access to every single day from the lawn, the garden, and the kitchen.

You can even re-cycle the leaves which fall during Autumn to make wonderful leafmould which is an ideal soil improver.

Compost is what happens when leaves, grass clippings, vegetable and fruit scraps, woodchips, straw, and small twigs are combined, then allowed to break down into a soil-like texture. Compost introduces and feeds diverse life in the soil, including bacteria, insects, worms, and more which support vigorous plant growth.

Compost is multi-faceted but not intended as a fertilizer. It offers only a relatively low proportion of nutrients, yet what it does is close to magical. In its finished form as mulch, it reduces evaporation, reduces or prevents weed growth, and insulates the soil from extreme temperature changes. Mulch also keeps the upper inches of the soil cooler in daytime and warmer at night.

Regardless of the particular ingredients, making compost is akin to making bread or beer; soil-digesting bacteria like yeasts need warmth, moisture, air and something to feed on to keep them alive and growing. Almost all of the practical problems associated with making compost stem from too much or too little of those basic factors.

Compost is created from layers of grass clippings, leaves, weeds, kitchen scraps and, if available, farm animal manure. If you have meat eaters in your home, don’t use their meat scraps as they will attract rodents. Also, do not use litter from your dog or cat; it doesn’t break down properly and contains too many pathogens.

Over the years, composting has gotten a reputation for being a time-consuming job, but this is not necessarily the case. You don’t need to build a big box or turn the pile every so often. A barrel, a hole in the ground or a pile on top of the ground is satisfactory.

The important requirement is to be sure the waste material is covered with soil, so it doesn’t attract rats, other rodents or flies. You can build your layers directly on the ground, without any frame at all; if you use a container, be sure it is well ventilated.

The trick to successful compost is balancing ingredients high in nitrogen; fresh grass clippings, other fresh, green plant matter, most kitchen scraps – with those high in carbon; leaves, straw, dried grass, washed eggshells, wheat germ or other milled grains that have become too rancid or old to use, and any dried, brown plant matter. Too much nitrogenous matter yields an anaerobic, smelly pile. Too much carbonaceous matter results in a pile that never heats up. The ideal ratio is one part nitrogen to three parts carbon.

Start with a layer of small twigs, no large branches, a couple of inches deep; this will help your pile to breathe. Then, keeping in mind the 1 to 3 ratio of nitrogen to carbon, add a layer of mixed plant material. You may enrich the pile with horse or cow manure. These materials don’t break down; they simply add nutrients to the final product. Then lightly water the pile so it’s evenly moist. Too much water will interfere with aeration; too little water and the pile won’t ferment. If your pile sits in the open, you should cover it if heavy rains are forecast. An 8-inch layer of straw mulch spread over the top of the pile serves the same purpose.

Alternate layers until the pile is 5 feet high by 5 feet wide by whatever length you choose. A properly made pile that is loosely packed and well aerated will reach an internal temperature of 160 degrees within a few days. It should smell like wet hay. If the pile fails to heat up, pull it apart and redo it by adding layers of fresh green matter. If the pile becomes anaerobic (is too wet to aerate), pull it apart, let it dry out, use it as mulch and start a new pile.

After three weeks, the pile will have shrunk in size; this is normal. Dig into the pile with a fork and completely turn it over until the contents are redistributed; the idea is to put unfermented particles in contact with those that are further along. Let the pile rest, so the temperature will rise again. Turn it a second time five weeks later, let it rest a few weeks and, with luck, you’ll have a rich, crumbly pile of “black gold.”

Aquatic Gardening

There are several points you need to consider before building your pond or water feature. Should it be formal or informal, natural or modern? Do you want to keep fish, grow plants or attract wildlife? Are there children to keep safe?

Once you have answered these questions you need to decide where you want to site the pond or water feature. A pond should be kept away from big trees and shrubs so ensure their roots don’t puncture the lining. If you want to keep fish you need to have a pretty deep pond to stop it freezing over the winter. The smallest you should build a pond is 60cm (2ft) deep and 1 x 1.5m (3 x 5ft) across. However, the bigger the better.

If childrens’ safety is and issue or you prefer not to have to maintain a pond then a water feature is an excellent compromise. You could build a wall fountain or a pebble pool which can be sited in sun or shade near to a power supply. If you do not have external power then a wide plant container or half a barrel, without drainage holes, is ideal. You can still grow small aquatic plants or use floating oxygenators such as water hyacinth. You will need to protect them during winter or empty the container and start again in the spring.

How do you grow your own cut flowers?

Buying cut flowers on a regular basis can be quite costly, so why not try growing your own in the garden?

They can be grown in their own cutting bed or mixed into a border to add to the display; either way you could raise enough flowers to have a constant supply of fresh blooms for your home.

To get the best quality flowers it is best to grow them in a sunny spot on well drained, fertile soil. Most will need to be supported to avoid damage and it is also wise to provide shelter from strong winds.

What typs of flowers can I grow?

• Half hardy annuals

• • The are the easiest to grow as the seed are sown directly into the soil where you want them flower
  • Sow between March and May, staggering the sowings to get a succession of flowers over the summer
  • Once all the flowers have been cut and no more buds form, lift the entire plant and put on the compost heap
  • Repeat the process next spring
  • Some examples are:
    • tobacco plants (nicotiana)
    • zinnia
    • snapdragons
    • cosmos
• Biennials
  • Sow seed between May and July to flower the following year
  • Sow where they are to flower or in seed trays
  • As with the annuals, discard after flowering is over
  • Keep sowing each May to get more flowers each year
  • Some examples are:
    • erysimum (wallflowers)
    • sweet william
    • dianthus
• Perennial
  • These will flower year after year so are a good investment
  • Plant rooted cuttings in spring or pot-grown specimens at any time
  • Perennials will die down for winter and most will be OK outside, however dahlias will need a good layer of mulch over them to help them through
  • Some examples are:
    • dahlia
    • chrysanthemum
    • alchemilla mollis
• Bulbs
  • Plant spring flowering bulbs at the end of summer or early autumn
  • Once the flowers have been cut and no more buds appear leave the foliage on the plant to die down naturally, this provides the bulb with food for the following year
  • Some examples are:
    • daffodils
    • tulips
    • allium

Most plants will benefit from being picked regularly as it will encourage more buds to form and extend your cutting season.

Keep all plants well watered throughout the growing season a feed every couple of weeks.

Flowers for Young Children

Question:

I am planning to make miniature gardens with young children and would like to use petunias ans Impatiens (bizzie-lizzie). I just wanted to make sure that neither of these plants is poisonous.

Answer:

Petunias and Impatiens are not on the poisonous plants list. However, if eaten most ornamental plants will cause sickness in children and some adults. You will need to keep an eye on the children when they are in the garden or consider planting edible plants. Here’s a selection for you to consider:

• Nasturtiums – colourful and quick growing
• Alliums – taste of onions with purple or white flowers
• Rosemary – grows quite big but can be pruned down. Smells great. The flavour is strong so the kids won’t like it anyway!
• Mint – lots of different types with slightly different minty smells. They can take over so it’s best kept in a pot
• Violas and Pansies – cheap and easy to grow
• Parsley – annual only but easy to grow in a sunny spot
• Try planting strawberries or small tomatoes in hanging baskets

The Gardening Register Rose

Here is the first photograph of The Gardening Register Rose.

For my birthday last year I was bought a Name A Rose Gift Box. In the box is sachet of seeds which you plant as per the instructions. Once done you fill in the Rose Naming form and send it off then back comes a Personalised Certificate confirming the rose name.

I am the first to admit that I never thought the seeds would germinate never mind turn into a healthy plant; infact, in my case two healthy plants.

Each plant has been trying to flower for a number of weeks but I kept removing the buds to allow them to concentrate on producing roots. However, while I was away over the weekend one of them went ahead and flowered. I think it’s a lovely colour and I’ll be very proud to have it in my garden.

It is highly likely that the second plant will produce a different flower, either in colour or style but that’s part of the excitment.

If I can bring both plants to full maturity I will propagate them over the years to come and may even offer them for sale!

Tomatoes and Olives

Question:
How do I nurture a tumbling tomatoe plant that we have hanging in a basket? How do I ensure a good crop? There are very small green baby tomatoes at present. Does it need repotting as it looks a bit big now for the basket

I bought the most gorgeous olive tree a couple of months ago. Its about 2.5 feet tall. I repotted it in John Innes No 3 mixed with grit. Is it right to keep it very moist initially? What feed, if any, should I use? How do I know its healthy?

Answer:
Your tumbling tomato plant will need lots of watering to stop the fruits splitting and it will need feeding every week with a tomato feed to ensure a good healthy crop. They really need to be in a very sunny spot for the fruit to ripen successfully. I have never been able to grow tomatoes outside as my garden is north facing and doesn’t get much sun. I wouldn’t re-pot it; it should be fine if you keep feeding and watering.

Olives are not entirely hardy in the UK so will need some protection during cold and frosty periods. You were right to plant in a well-drained mix of compost and grit. Although they can cope with dry periods, olives in containers need regular watering and feeding to produce fruit. During the growing season keep the compost moist and feed every month. In winter, you can reduce watering, but don’t let the compost dry out completely. As long as the leaves are undamaged and there is sign of new growth you can assume the plant is healthy. If the plant is kept in a very sunny location you may even get fruit after a couple of years.

Moving Monkey Puzzle Tree

Question:
We have planted a monkey puzzle tree from a container it did not have very big roots but looked very healthy a couple of the bottom branches are dying but the rest looks ok can you give me any advice on growing and feeding my tree as I would hate to lose it.

Answer:
All trees and shrubs take time to get established following a move, as long as you are keeping it well watered it should be OK.

However, the monkey puzzle trees like full sun and well-drained soil so check that it isn’t sitting in water and move it to a sunny area if it isn’t located in one currently.

The monkey puzzle tree is slow growing but can eventually grow to a height of 60-70ft and a width of 30-35ft so may eventually outgrow your garden. I know you’ve only just moved it out of a container but it may be better to grow it in a pot but the pot needs to be of considerable size in order for the tree to reach it’s full potential. Make sure you feed it regularly with a general feed such as pelleted chicken manure and mulch the surface with some well rotted organic matter such as manure. If it out grows its pot, wait until the autumn then re-pot in a large pot with plenty of drainage holes. Add some crocks or broken clay pots into the bottom to help drainage and to help stop it falling over, then fill with a good quality compost. Add a general feed such as pelleted chicken manure and mulch the surface with some well rotted organic matter such as manure. Each year you should top up the compost level, feed and add more organic matter.

If you do want to keep it in the ground keep it well watered during the first year and feed and mulch in the autumn.

Leylandii Hedge

Question:

I have just moved into a new house and there is a 20 foot high leylandii hedge down one whole side of the garden.  The bottom is a bit sparse, and I really want to plant a border in front of it.  Can you please give me any advice about what plants would survive?

Answer:

Leylandii are a nuisance in the garden as they grow very quick and if not kept in check can soon take over a whole garden!

It is extremely difficult to grow anything under a hedge, particularly leylandii as they remove so much moisture from the soil.

I would not advise trying to plant a border under the hedge as the shade and lack of moisture means that not much is likely to grow there successfully.

I would plant up pots to provide colour and interest, just place them under the hedge and keep them well watered.

Try planting a few pots with spring flowering bulbs layering different types to get a succession of flowering e.g. daffodils in the lower layer, followed by tulips, then crocus or iris; anything that takes your fancy will do. Once flowering is over these pots can be moved into a corner out of the way until next spring. Replace them by pots full of summer bedding plants.

For all year background interest you could have your evergreens and grasses; conifers also do well in pots and their size is kept in check.

A good plant for autumn interest is Skimmia, they don’t mind low light and are great in pots. click here to see a selection from Crocus

Questions for April 2008

Question

I am not sure if you can help but I am looking to buy some coprosma evening glow or/and coprosma fire burst so far I have had little luck I have tried googling it but very poor results none of my local garden centres stock it I bought some last year from a local market and would like to get more I really want a fairly well established rather than a small gutting that needs to be grown on do you know of any online nurseries that would sell this also regards dogwood I really like the look of this but again not been able to find it in my garden centres does this come in the form of a shrub or bush has its something I am not familiar with thanks for any help you can provide

Answer

I have to admit to not knowing about Coprosma but I have managed to find a company who sell a few varieties. Click on this link:  http://www.burncoose.co.uk/site/plants.cfm?pn_id=176. There are several types of Dogwood (Cornus) so I have added a link to a few at Crocus for you to look at.

Question

We have a well established pear tree in our garden. The problem is that is has grown lopsided / horizontally right across the garden, so much so that it is obstructing the garden path. I would like to keep the tree but would like some advice on how to prune it to encourage it to grow upwards rather than outwards.

Answer

It is possible to do what you are asking but it will need to be done in stages as to reduce the stress to the tree. I think the best thing for you to do is to follow RHS advice on this matter so I have included a link below on Apple and pear tree renovation: http://www.rhs.org.uk/advice/profiles1101/fruit_tree.asp

Question

I have what seems to be three different type of spotted laurels one is dark green in colour the other light green with what seems like the beginning of possibly some flowers the other is the same colour light green the first two were planted around a month ago and around 2 3 ft the last one was planted last summer and has hardly grown at all I did read for these to produce flowers you need a male and female like a holly and I thought they were very quick growers I have seen some has high has well over 20foot round where I live they seem to get bigger every year mine are planted in full sun in a good quality compost any information on this plant would be welcomed thank you. I bought a shrub called a beauty berry in October last year it had a abundance of purple berries which have gradually dropped of I believe it is suppose to have pink flowers in summer but at moment I have just a bare shrub is this normal

Answer

Regarding your laurels; do you know which variety you have? I have detailed three of the more common ones below and as you can see their sizes and flowering requirements do vary. If you can find the actual varieties I can do more research for you.

• Aucuba Japonica Crotonifolia. Evergreen, bushy, dense shrub with stout, green shoots. Large glossy, dark green leaves are heavily mottled yellow. Grows in sun or shade and well drained soil. Height 1.7m Spread 1.7m. Male.
• Aucuba Japonica Rozannie. Very handsome shrub which has large, toothed and leathery green leaves. This all green form is self pollinating and produces large red fruits in winter. Grows in any situation and any soil to about 1m. Male.
• Aucuba Japonica Variegata. Evergreen, bushy, dense shrub grown for its yellow spotted leathery leaves. Height 7 ft. Spread 7 ft. requires any reasonable soil. Will thrive in sun or shade. Plant with crotonifolia for berries. Can be kept as a colourful hedge or as a specimen plant. Female. As regards your Beauty Berry (Callicarpa bodinieri var. giraldii Profusion). The lovely purple berries will gradually drop off, or get eaten by the birds, before the end of the winter which is normal. It will remain bare until it begins to produce its leaves then small pink flowers around July.

Question

I have got some branches on our pear tree where the buds are not opening – should I cut them back or just leave it?

Answer

If the tree is the right size and shape for you then I’d leave it. However, you may want to read the RHS article below for information on how to prune your tree should you wish. http://www.rhs.org.uk/advice/profiles1101/fruit_tree.asp

Question

Now that the buds are out on the roses does this mean that I can cut them with an outward facing slope away from a bud at a height of 6 inches from the base now? Can I cut the honeysuckle back to 6 inches as well now?

Answer

I would wait until all risk of frost has passed because if you get a hard frost it can cause the tips of shrubs to die back. This die-back can be trimmed off but if the shrub is at its lowest height you will have nothing left to trim away. You should be OK to do it at the middle of April. You will still get a good display so don’t worry, you’ll be surprised how quickly they will grow from May onwards. You method sounds good but don’t forget to give them a little feed of fertilizer. You can buy one specifically for roses or you can use blood, fish and bone meal which can be used on all your plants. A mulch of well rotted manure around the base will also be good to keep down weeds and help improve the structure of the soil.

Question

Leaves on the hyacinth are going yellow. Can I cut them to the base; remove bulbs from the indoor pot and plant in the garden now? Any thoughts as to where best and how i.e. depth etc to plant them?

Answer

Yes you can cut them back and plant them out in the garden. Here’s a link to my Bulbs page which should help you when planting but the general rule is three times its own depth in a sunny position. http://gardeningregister.co.uk/NonProductPages/Articles/bulbs.htm

Question

I have recently bought some of the pretty flowering heathers you see at this time of year but know little about them I did hear that they need to be planted I the special compost you use for azaleas and rhododendrons also how long do they flower for I am told the ones you see in the garden centres are all forced has I believe they do not flower until early summer do I prune them when they finish flowering and when should I feed them thank you for any advice you can provide

Answer

There are two types of heather so I’ll give you the details for both. The first type is the “Erica” variety. These heathers do prefer acid soil but they will tolerate slightly alkaline soil, either way it needs to be well-drained and placed in a sunny spot. If you don’t know how acidic your soil is then it would be best to plant into pots using Ericaceous compost although it’s not essential. This type of heather flowers January to March and should be trimmed after flowering with shears or secateurs to remove the dead flowers and encourage bushy growth. The second type is “Calluna”. They like full sun and well-drained, humus-rich, acid soil or ericaceous compost. They flower July to November. In March or April cut back the flowered shoots to within 2.5cm (1in) of the old growth.

Question

My husband would like to know are than any certain types of methods used to make top soil more firm? He’s clearing out some land and the soil is too soft to hold weight.

Answer

I’m not entirely certain I understand exactly what the problem is but I think it is one of the following. The top soil may be too “soft” meaning it is not compacted enough. If this is the case then you should be able to carefully tread down the surface by slowly walking around until it is firm. However, the problem may be that the soil is too sandy, meaning that it has no substance and keeps falling apart. The added problem here is that it will also be very poor making it difficult to grow anything. If this is the case then you need to improve the structure by adding lots and lots of well rotted organic matter such as horse or cow manure. This can be bought in bulk or, if you live near a farm or stables, you may get it for free if you agree to collect it. If you have to go this route then it will take some time for the soil to change and become more substantial, perhaps as long as a year. To avoid weeds taking hold while you’re waiting you could grow some green manure which will subsequently be incorporated into the soil, again adding goodness. Here is an article which might help. http://gardeningregister.co.uk/NonProductPages/Articles/soil.htm#Green_manures0

Questions for March 2008

Question

I bought a Grevillea plant today the guy at the garden centre just said it grows to about 3 feet and flowers until June I have since found there are many types mine has pink and black flowers on pine like branches what is the general rule of where to plant type of soil etc any tips welcomed thank you

Answer

It seems to be quite tender and prefers a light, sandy soil. Plant it out in a sunny, sheltered spot and perhaps protect it when the weather is severe. You shouldn’t need to prune it unless you want to keep it to a certain size or shape, if you do wish to prune it do it once flowering has finished.

Question

I want to replace my Acer in the garden. Is it ok to plant a new one in the same place as the one I am now digging out?

Answer

As long as the Acer you are replacing is healthy then I can see no reason why planting another would cause problems. Ensure you remove all the roots of the old tree and dig a hole twice the size of the root ball of the new tree. Add lots of well rotted compost to the soil when back-filling. Water if it doesn’t rain but ensure it doesn’t get waterlogged.

Question

I have a wisteria tree which is well established (over 25 years); it is situated in my front garden and has been trained to grow over an archway and along the side of my garage. We have invested in a larger vehicle and as a result need to widen our driveway area which impinges on where the wisteria trunk is sited. As we will be digging up this area to lay a new driveway and paving area, rather than lose the wisteria, we wondered whether once the roots are exposed whether it would be possible to re-site the trunk a few metres away and re-bed in the new paving without causing damage to the tree.

Answer

I am not confident that you will be able to easily re-site your wisteria.  As a rule a tree’s roots spread the same distance underground as their branches do above ground so I would doubt that you would be able to remove all the roots without damaging them and therefore risking the tree. Having said that it sounds as if you have to remove the tree anyway so it may be worth the risk. If you decide to go ahead you should dig a hole in the new location before you begin removing the tree. Make sure the hole is wide enough and deep enough to contain all the roots and add lots of well rotted compost to give it as much help as possible. You may need to detach some branches from the support wires prior to moving. Once you are ready, carefully expose as much root as you can and only cut off roots if absolutely necessary. The most important roots are the smaller fibrous roots which take up the goodness in the soil, the bigger roots are there to hold the tree in place and seek out water further below the surface. Before laying the new paving give the tree lots of water each day for as long as you can to help it establish. If it does happen to die off you could always use it as support for another climber such as a clematis or honeysuckle.

Question

I bought a Cistus snow white yesterday and planted it by the instructions on the plant card however when I looked on the Internet it says not to use organic compost not to mulch and not to feed I used multi purpose compost give it a feed with miracle grow all of which the plant card suggested will it harm it or should I dig it up.

Answer

Cistus plants are originally from the dry, rocky soils of the Mediterranean, which means that they like poor, sandy soils so do not need fertile soil or fertilisers. I must admit that when I planted my first Cistus I also used compost and feed and it did OK. You may find it possibly won’t do as well as had you planted it in poor soil but as long as you don’t add any more mulch or feed then it will be OK in future years. However, if you have only just planted it, you should be able to dig it up quite easily if you prefer to replant. If you do just dig a hole and pop it in! The good news is that this plant copes with fairly extreme droughts so does not need much watering and loves strong sunlight. Also, this is one of the few Cistus plants that respond well to occasional pruning of its stems.

Questions for February 2008

Question

I have a Xylosteum (fly honeysuckle) growing in my garden. Please could you tell me if the red berries growing in the winter are poisonous? I have several young children and am concerned for their welfare.

Answer

The berries on the fly honeysuckle are mildly poisonous so I wouldn’t > take a chance near small children.

Question

We have recently purchased a property with a Bore, the Bore water has a high Iron content, and although my newly planted garden isn’t affected by this my neighbour has reported that he has lost his plants due to the Iron levels in the water. So my question is will the Iron affect the growth of my plants? (The Iron level isn’t extreme; it is still suitable for drinking)

Answer

I have tried to do some research on this but can’t find an awful lot on the subject. The usual problem in gardens is lack of iron as a lot of plants are unable to absorb the iron the soil. I would think that as long as you look after your soil and plant good quality specimens your plants should be OK. Keep the site well drained and add plenty of well rotted organic matter each year to improve the structure. Sorry I couldn’t offer more help.

Question

I live on a estate where when I come out of my flat I come on to a dark outside landing that gets little natural light I was wondering if there was any type of trees shrub I and my fellow neighbours could put in to pots that would brighten the place up I would like some thing that would grow to around 6ft I did thing about conifers but I believe like a lot of trees and plants they need a fair amount of sunshine and /or natural light if you can think of anything I would be grateful preferably something that would be evaluable in your average garden centres

Answer

Firstly you could try ferns. These come in various sizes, not as tall as 6ft but some can reach 3ft and have a good texture. Alternatively, why not put an obelisk into a container and grow ivy up it, twining it in and out as it grows to make it bush out. There are some lovely brightly coloured ivy such as Sulphur Heart. For a long term investment you could try a climbing hydrangea. I have one on the back wall of my house. It faces north and never gets any sun, it won’t grow as big as it says in the description and you can prune it each year if needed and it still flowers well. Here’s a link so you can see what it looks like. http://www.crocus.co.uk/plants/_/climbers/other-climbers/hydrangea-anomala-subsp.-petiolaris/itemno.PL00003342/. For a short-term show you could try a few hanging baskets or containers filled with Busy Lizzies. They won’t flower as long or as bright as when they are in sunlight but you should get a few weeks out of them and they will tolerate being dried out if they don’t get watered for a while. In all cases you will need to ensure the soil is of good quality and add some well rotted organic matter to help retain moisture. Either re-pot or top-up the containers each year to keep them fresh.

Questions for January 2008

Question

HI, I need some advice please on what to do with an old veggie patch in my backyard. The previous owner maintained a veggie patch, taking up about one-third of the yard.  It is no longer maintained as a veggie patch and if I could afford it I would makeover the whole backyard.  That area is now just a patch of dirt that is overgrown with weeds.  The man that mows my front lawn previously cleared it, but then I found that the loose soil was unsightly and would blow onto the paved area on windy days. It also had a lot of debris in it (from old construction work on my house, bits of broken plaster) that was unnoticeable while the weeds were growing over it. How do I keep the patch looking neat, would it be possible to cover it over with gravel or wood chips?  I don’t want to spend a lot of money by putting a lawn over it as I intend to redo the whole area someday.

Answer

It should be quite easy to deal with this area. First of all I would ensure that all the weeds are well and truly dead by treating the area with a good quality perennial weed killer. Leave it for a few weeks to see if any annual weeds germinate and if they do pull them out by hand. Then you should lay a weed suppressing membrane ensuring that the whole area is well covered. You will be able to buy this from your local garden centre or DIY store. Finally lay a thick layer of your chosen mulch. You can use anything you like as they all do the same job. The thing to remember is that weed seeds will find there way into the mulch and germinate. However they are usually quite weak so if you pull them up as soon as you see them they should be quite easy to control.

Question

I have just bought a lovely Cordyline australis red star it says on the plant card its only half hardy and wont survive hard frosts yet elsewhere I have read its fully hardy and the frost wont damage it I have bought it in doors placed it where it can get plenty of light and avoided putting it near radiators so should I keep it indoors for now or plant it out it is in a large black plastic pot at moment I have other Cordylines which have done ok over last two winters though different from this one

Answer

You are correct that some Cordylines do survive the winter but I think it best to play safe. Leave it indoors over this winter and plant it out into a sheltered, sunny spot once the risk of frost has passed. Next winter cover the leaves with horticultural fleece to protect it. Alternatively plant it into a nice pot and bring it indoors each winter.

Question

I have a very shaded area of my garden 5 6 hours max sun on a good day in summer I was looking at a relatively inexpensive way of planting some form of hedge that will not grow much over 3ft but will be noticeable perhaps something that may have flowers or berries on at some stage in the year any advice welcomed

Answer

I have done some research and found a few plants which should make a good, low hedge with some interest. There are not many hedging plants which like full shade so I have also included some that like partial shade. They should still do OK although they may bloom a little later than usual. Switch Ivy – likes acid soil, Snowy Woodrush – I don’t know this one well but enjoys full shade, Common Box – needs to be kept well pruned to shape, Berberis – likes sun or shade. Lovely colour but has thorns, Pyracantha – also like sun or shade but again is thorny and will need pruning well each year, Red-barked Dogwood – the red bark is even better when cut right down each year.

Questions for December 2007

Question:

I recently bought two holly trees one was a standard ilex with plenty berries the other I was told was a female has well but has a couple of berries on it so I assume that must be female has well I have been told I need a male nearby has I have not seen any in my area I am a bit confused has there is so many on the market but basically my question is will any male holly do for the female has I have been told there is only a one in 50 chance of getting a female of the same family thanks for any advice

Answer:

You are correct that you require a male ilex to ensure berries on your female plants. One male can fertilise up to five females. Be careful when buying your male plant as some have names which sound female, e.g. Silver Queen.

Question:

I wonder if you could help me please. My umbrella plant has started losing leaves and I am worried I am doing something wrong. We live in Turkey and during the summer it was unusually hot and while we were in the UK I don’t think it was watered as well as it could have been. It lost quite a lot of leaves during this time and although it has had lots of TLC since I am worried it may still be suffering the effects of the heat. I have sprayed with leave shine I do not overwater and it stands in a south facing light spot in our lounge. Can you offer any suggestions please?

Answer:

The Umbrella Plant likes to be kept moist but does not like to sit in water so it could be that, as you say, it was either not watered or indeed overwatered. When a plant goes through trauma like this is does take a while for it to recover so I wouldn’t give up hope just yet. Here are some care instructions which may help. It likes bright but indirect light so as long as it is not near a window it should be OK in your lounge. It needs to be kept warm over the winter at a minimum of 60°F. Water well over the summer months and less over the winter. Place in a pebble tray or mist regularly to keep up humidity. Feed a liquid feed every month over the growing season. If it is still not looking good by summer you may want to consider cutting it down and seeing if it will re-grow from the base. There are no guarantees that this will help so use it as a last resort.

Questions for November 2007

Question:

I live in a very mossy area and found last year that my 30 year old very productive asparagus bed was completely covered in moss. I raked off as much as was possible but this year it has unsurprisingly returned. I have again raked off but clearly shall be left with no soil if I continue in this way. Any suggestions please as to a moss kill product I could now apply (the fern has been cut down to less than an inch above the ground – (might lawn sand be suitable?) and also how I might deal with the bed from now on to minimise moss formation in future? (I do not feel I should just leave the moss on the bed hoping that the asparagus will continue to crop through it. Would this be a sensible option?)

Answer:

This is quite a difficult problem. Firstly I would say not to use any type of moss killer on the bed as the risk to the asparagus is too great. I assume that the soil conditions are ideal for your asparagus otherwise they would not have lasted so long, however, moss loves damp ground. If it is possible to improve the drainage of the bed without disturbing the asparagus you may find this helps in the longer term. In the short term you could try removing the moss by hand then adding mulch, replacing or topping it up every year. The uneven surface of the mulch is less appealing to the moss than the smoothness of bare soil.

Question:

We have 1/2 acre, was a field. Wet and clay, windy site. We tried planting as a wet meadow but got inundated with weeds and thistles. Is there anything we can plant which would take up the wet and cope with wind? Preferably not grass!

Answer:

I would be tempted to build a good sized natural pond and plant the surrounding area with moisture loving and bog plants. You could use the excavated soil to build a mound which could be turned into a wild flower meadow or add some grit and grow non-moisture loving plants. I have found a great article from English Nature which tells you all about ponds and native plants http://www.english-nature.org.uk/pubs/publication/pdf/GardenPonds.pdf. My own article also has some ideas together with selected suppliers of aquatic merchandise which may also help. http://gardeningregister.co.uk/NonProductPages/Articles/aquatic_gardening.htm

Questions for October 2007

Question:

Please could you tell me whether the fuchsia “Shadow Dancer” is hardy?

Answer:

Your Fuchsia “Shadow Dancer” has a hardiness rating of H3 which means that you need to give it some protection from frost. Either move it into an unheated greenhouse or cover with horticultural fleece when frost is expected.

Question:

I have bought several small cuttings today of Buxus golden dream how big can this grow in height and spread and does it grow all year round should I water and feed it in winter thank you for any advice you can give.

Answer:

Buxus ‘Golden Dream’ is a compact, evergreen shrub with dense foliage. Its colour is most pronounced in full sun, but will it will grow in either full sun or partial shade. This plant can be used for anything from a low growing hedge to a nice, neat, accent in any garden. As with most all boxwoods, it prefers slightly cooler, moist soils with good drainage. A good top dressing of mulch will do wonders to keep the soil conditions favourable. Its height and spread is 3-4 ft and it grows at a moderate rate. Although this is a hardy shrub if the cuttings are particularly small I would keep them in their pots and protect them over this winter, planting them out once the risk of frost has passed next spring. They shouldn’t need any feeding this winter but make sure they don’t dry out. When you plant them out give then a good mulch of well rotted manure.

Questions for September 2007

Question:

Could you let me know how to prune Iceland Poppies?

Answer:

Iceland Poppies are Biennials which means that they flower the year after they are sown and then die. Therefore, they do not require pruning. Once they are past their best pull them up. They often seed themselves so you may get flowers year after year.

Question:

I have a strawberry barrel.  Can I pot on the runners which appear to have small roots and do I leave them attached to the main plant until established?

Answer:

Yes you can pot on the strawberry runners as long as they have rooted. Just detach from the mother plant and put in small pots with a good quality potting compost. Give them a good watering to get them going. They should be OK outside in a sheltered spot but if you have a cold greenhouse that would be good too.

Question:

I know this is probably a stupid question but I am a beginner gardener I was wondering whether I could plant a Christmas tree in the garden that I have bought from a garden shop and will it still grow many thanks sorry for the silly question

Answer:

Good afternoon, thank you for your email. It is not a silly question really as it does depend on what type of Xmas tree you have. Although the majority of Christmas trees are sold with a cut trunk but some are sold in pots with their roots intact. Although they tend to be more expensive, they do last a lot longer and have the added advantage of being able to be planted out in the garden. Follow these guidelines for the best chance of success:

• If it has been kept indoors it will need to get used to the cold weather before planting it out
• When you are ready to plant it out stand it in a bucket of water, still in its pot, until it’s thoroughly wet It will grow very big so choose its final position carefully
• Dig a hole twice the diameter of the pot and the same depth as the pot
• Add some organic matter into the bottom of the hole e.g. well rotted manure or good quality compost If you’re planting in the spring sprinkle in some general fertilizer too
• Remove the plant from its pot
• If it is pot-bound (the roots are tightly packed in the pot) tease out a few of the biggest roots
• Stand the plant in the hole with its best side facing the direction from which you’ll normally view it
• Check that the top of the rootball is level with the surrounding soil, and that the plant is standing upright
• Mix more organic matter with the excavated soil and fill in around the rootball
• Firm gently with your foot
• Water thoroughly
• Spread an layer of mulch
• Keep well watered for the first few weeks regardless as to whether it rains or not
