Looking after your lawn in Winter

Try to rest the lawn as much as possible during winter. If practical keep off when wet or frosty, as the grass plants are not actively growing; they will not repair themselves if damaged until the spring.

Mowing

Only mow the lawn if necessary; this will depend upon weather conditions and temperatures at the time. Do not mow if heavy frosts are expected or if the ground is very wet.

Clear leaves and debris

Use a light rake or brush to keep the lawn free of leaves and debris. Specialist leaf sweepers and lawn vacuums are available for hire from local garden centres or DIY stores for larger lawns; although in winter it is better to keep off with heavier machines.

Aeration

Aerate consolidated areas of the lawn with a hand fork or with a spiking machine. These are available for hire from local garden centres or DIY stores for larger lawns. This will relieve compaction, improve drainage and allow more air into the root system leading to a healthier lawn.

Dealing with worms

Remember worms improve the nutrient content of a soil and are beneficial to the soil structure. Worm casts are best left to dry and then swept or brushed away with a stiff brush.

As leaves fall from the trees use a light rake or brush to keep the lawn free of leaves and debris.

Service mower

Service or replace your mower if necessary ready for the next growing season. As always make sure that the blades are in good condition and are sharp.

Frosty/Snowy Weather

Filed under Chat

It seems the whole country has very low temperatures leading to morning frosts, some areas also have snow!

During this cold spell try not to walk in your lawn as it could damage the grass.

Also, leave out water for the birds but check it every morning, defrosting it if necessary.

Tender plants should be covered with fleece or moved into the greenhouse or conservatory.

Flanders Poppy (Papaver Rhoeas Flanders)

November 12, 2010 by  
Filed under Flowers and Plants

Papaver rhoeas or Flanders Poppy is the common red poppy familiar to millions as the symbol for Remembrance Day.

These bright scarlet red flowers add a bright splash of colour in areas where you may struggle to grow anything else and as they self seed in their hundreds they are extremely low maintenance.

One thing to note is that the seed can lay dormant for years until the soil is disturbed sometimes making it difficult to germinate, however, if you gently rake the surface of the soil around the area you will give them a helping hand.

They need a weed-free light soil and love hard frosts and warm spring days. Prepare the soil by lightly raking the surface and broadcast sow during autumn or in early March. If you do not get a display in the first year, rake over the area and you should get germination in the second year.

They flower in early summer and reach between 18 and 24 inches in height.

What’s looking good in September

September 9, 2009 by  
Filed under Plants in Our Garden

Rudbeckia with Euonymus alatusThe Gardening Register garden is getting ready for winter but there are still a few plants worth a mention.

Here is a picture of our Rudbeckia laciniata ‘Herbstsonne’ (see plants in our garden for more information) together with Euonymus alatus compactus. The Euonymus is a very unusual shrub with distinctive corky wings on the stems. It has dark green leaves which turn a bright pink in autumn. The colour does not come over very bright on the photograph so if you get a chance to see it in real life I’m sure you’ll fall in love with it.

Phlox paniculataAnother late bloomer looking great is Phlox paniculata. I’m not sure of the exact variety but it is a lovely clear white. My mum has had this in her garden for years and this is part of her clump which I put in a few years back. I moved it last autumn into a better spot and it seems to like it.

Chinese dogwoodI thought I had told you about my Chinese dogwood (Cornus kousa var. chinensis) back in the summer when the bracts were glorious but I didn’t. So I thought I’d show you how it looks in September. These bright red fruits appeared about four weeks ago and look as if they will last well until the frosts.

Crocus.co.uk are selling this wonderful tree; here’s what they say: A real showstopper of a tree, with two seasons of interest. Broadly conical in shape, it produces tiny green flowers in June, surrounded by showy creamy white, flower bracts, that fade to lovely shades of pink. In autumn the dark green leaves turn crimson-purple and mature trees produce strawberry-like fruits. It’s an excellent specimen tree for a small garden or woodland edge, and the leaf colour is best in fertile, well-drained, neutral to acid soil. Click here to buy it now.

Plant of the Month for September – Japanese Anemone

September 7, 2009 by  
Filed under Plants in Our Garden

anemone-september-charmOur 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

Victoria Plum Tree

July 2, 2009 by  
Filed under Q&A

Question:
I planted a small Victoria Plum Tree last year in spring, I have no blossom this year only leaves, is this normal?

Answer:
Most fruit trees are very hardy but once they start into growth in spring, flowers and buds are especially vulnerable to frost. It may well be that the flower buds were affected by the frost and died. Next year in early spring cover the tree with horticultural fleece until all risk of frost has passed.

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 January 2008

July 2, 2009 by  
Filed under Q&A

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 October 2007

Filed under Q&A

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 August 2007

Question:

I bought a lavender tree lavandula dentata I planted about 6weeks ago it does say its hare had only the odd night of frost but don t expose to prolonged frost we have had only the odd night of frost since I bought it I have noticed today there are one or two brown spikes on it and the rest seem to be drooping I have given it a feed of miracle grow rose and shrub food I am been unduly concerned will it perk up when the weather gets warmer and is there any thing I can specifically do to help it.

Answer:

Unfortunately Lavandula dentate (French Lavender) is not hardy in the UK so should be kept indoors during the winter. You could try bringing it in now, keeping it warm for the next few weeks to see if it perks up. Don’t cut off the brown spikes just yet. If you still have some green growth by the end of April then prune it back before placing outdoors for the summer. Be careful not to prune into any old or brown woody parts of the plant as it will never re-grow from these areas.


Question:

I would like to know if I could put my magnolia in a container as I am moving house and the garden is all slabs, it is around 2 to 3 years old and around 4 foot.

Answer:

My mum has successfully grown her magnolia in a pot for years and it always looks good. I assume it is in the ground at the moment so you will have to carefully lift it ensuring you don’t damage the roots. Make sure it doesn’t dry out before placing it in as large a pot as possible. Put lots of crocks in the bottom to help drainage and add a slow release fertilizer to the soil around the plant. Each year top off the plant with new compost and / or manure to keep the soil well fed. You may find it goes into shock this year but it should be OK by next year’s flowering season. You will find that the plant won’t grow as big as it would if it was in the ground and it may not live as long either.


Question:

I currently live in West Sussex and do hope that you can give me some advice on the Meyers lemon tree that I purchased last year. You see I am new to the way of gardening here in England, as I spent most of my gardening life in the tropical area of South Africa where it never gets really cold. As I have already mentioned I purchased a lemon tree, which I put into a huge pot on my patio, but now I see that during the course of winter it has lost all its leaves and a lot of the tips of the branches have gone brown. I did not place it indoors, as I do not have the strength to be lugging it around – nor did I cover it with anything. My question is do I throw the tree away or do you think it will pick up again in spring.

Answer:

Unfortunately citrus plants will not survive outside during an English winter. However, having said that, if you have not had a hard frost and it’s in a sheltered position then you may get away with it. I wouldn’t give up on it just yet. Buy some horticultural fleece (available from garden centres or the larger DIY stores, cover it for the rest of the winter and make sure it doesn’t get too wet. If it’s survived you should see new leaves appearing when the weather warms up during April/May.


Question:

Can you please tell me any plants besides Aubrietia that you can plant in the top of a walled raised bed to hang over or to plant vertically in the wall?

Answer:

Please find below some suggestions. Most of these are alpines and do require a well drained soil. Cerastium (Snow-in-summer) – colour: white Iberis (Candytuft) – colour: white Linaria (Toadflax) – colour: various – there is an upright version of this too Saponaria (Soapwort) – colour: pink. You could also consider planting a nice coloured, small leaved ivy to trail down and plant some low growing alpines, such as Thrift to add some height. If you don’t mind a bit of work you could consider planting trailing geraniums or other colourful annuals each year.


Question:

Our neighbours have just built an extension, the side wall of which overlooks our back garden. Unfortunately, a variety of bricks have been used and they haven’t been spaced out very well with the result that the wall overlooking our back garden is unsightly and also oppressive. We would like a fast growing plant which would hide the wall. The wall goes up to 310 cm in height. Please could you advise us as to what would be the best plant to hide this wall and which would grow quickly?

Answer:

My ideal would be ivy. There are lots of different varieties giving you a wide selection of leaf sizes and colours which are evergreen. Once established it is extremely fast growing and also has the benefit of being able to climb without support and will grow in any situation. The other is the Montana range of Clematis which again is very fast growing and has the extra benefit of fragrant flowers in the spring. However you will need to erect some sort of support structure such as trellis or wires before planting. A sunny site will give the best results. Which ever plant you choose make sure you don’t plant it too close to the wall as it won’t be able to get as much water as it needs. If you go to my Plant your Garden page http://gardeningregister.co.uk/NonProductPages/Articles/planting.htm.  You will see an advert from Crocus. If you click the Climbers box you will be able to enter some information about the location and features required and receive a number of suggestions back.


Question:

I’ve got a question about holly trees that you might be able to answer for me…! As you know – you need male and female holly for the female plant to produce berries, but do the male and female plant need to be the same variety?? I have a silver queen (male) and a golden king (female) – will I get berries from this??

Answer:

I have double checked and you only need to have one male holly, of any variety, to pollinate several female plants of any variety. Therefore the two you have will do fine; the female plant will produce the berries, not the male. If you’d like more berries you could buy another female variety.


Question:

I am the General Manager of a psychiatric unit in London. We have recently built a secure steel balcony to provide additional outdoor space to one of our first floor wards. The construction is a ‘metal cage’ with a very raw look to it and I would appreciate it if you could give me some ideas on the types of plants we would use to brighten up the area. The balcony is south facing and I would preferably like ones that are easy to manage and stay evergreen so there is colour all year round. Have you any suggestions. The main problem is that for safety reasons we can not use climbing plants as patients could use these to climb up and fall, we can not use plants that have poisonous leaves or berries as patients could eat these and we are unable to use plants that have sharp edges as patients may use these to self harm or ones that attract bees in case of allergic reaction to possible bee stings. In addition, we would require the plants to be in pots that are too heavy for a patient to lift in case they throw them. As you can see from a non-gardeners point of view I am struggling to find the appropriate plants and your assistance and advice would be very welcome.

Answer:

I’ve come up with some ideas and attach an outline of a plan which may be of interest. My first thought was to fit a bench across the left-hand 2.4m section. This could be attached to the balcony and would allow seating for a few people. I have also left room for quite a large table and six chairs. Your idea of galvanized containers screwed into the patio seems a good idea and I’ve found a couple of sites which may be able to provide them. and http://shop.theurbangarden.co.uk/product_select.asp?prtID=49&d=planters. The alternative is to have a raised bed built into the corner which is also attached to the balcony as per my plan. You could have it built as one big “box” or if you had six separate boxes they could be tiered so that the outermost ones are lower than the top ones. This would provide more interest and allow for plants to cascade the corners of each “box”. As for plants. My initial thought is to use Herbs. These are usually soft and are, of course, edible. For added interest I thought a few grasses. I have found a few examples of my thoughts on Crocus.co.uk and have attached a link to their page so you can find out a little more about them. Fennel (especially Bronze which is a lovely colour) these grow to about 1.8m but not very wide so you could fit in quite a few. They are light and move with the wind giving a feeling of movement. I find it best to snip off the flowers to avoid them going to seed and ruining the look. Also, they will die down for the winter but this also means it doesn’t take over. To compliment the colour and movement of the Fennel I thought a few soft grasses would be nice. They tend to give great autumn colour and if left over the winter they provide structure and look nice when frosted. They will have to be cut back to allow the new growth through but it’s not a hard job. Here are a couple of examples. For an evergreen look I think Rosemary would be good. They can grown quite big so may need keeping in check but they are very hardy and don’t require much maintenance. They are usually a rich dark green with lavender/blue flowers during the summer. To compliment the rosemary how about Lavender. There are lots of varieties around but you need to have a good hardy one to see you through the winters. To break-up the front of the containers/bed I suggest planting a few “lesser” periwinkles. These come in white, lilac or purple in lots of different shades. The leaf colours also differ so you could find one you like. The “greater” periwinkles have bigger flowers and grow too big and fast for containers. Just tuck them into the corners of each “box” and let them hang down. They do spread so you may need to pull them up to avoid them taking over the whole container. Finally, I thought the little space near the entrance could do with something. Mint is a great herb but extremely invasive so it is ideal in its own container. There are lots available, such as pineapple mint and apple mint so again you should find some you like. They will die down for the winter but will come back each spring. Regardless of the containers you use you will have to ensure that there is adequate drainage in the bottom. Punch some holes in the base of the containers and lift them slightly off the floor. To help the drainage and keep the weight down fill the bottom of the containers with a good layer of polystyrene which you get in packaging. Use good quality compost and add some vermiculite which will also help keep the weight down but will also aid drainage. I would also add a slow release fertilizer and some water-retaining granules. You won’t be able to use hard mulch so I would top off the planting with a good layer of well-rotted manure. This will help retain moisture, keep weeds down and add goodness to the soil. Each autumn you should add another layer.


Pruning Penstemons

December 18, 2008 by  
Filed under Q&A

Question: Do I cut back PENSTEMONS before winter or leave them alone? Answer: It is best to leave Penstemons over the winter the old stems help to shelter the new shoots from frost. In late April or early May you need to have a look at each plant. If the plant has new shoots growing from the bottom of the plant you can cut down all the old stems to ground level. If there are no new shoots forming, then just shorten each stem by cutting just above the lowest set of leaves. After pruning apply a general fertiliser to encourage strong growth.

Overwintering Cannas

November 8, 2008 by  
Filed under Q&A

Question: What do I do with my canna this time of year it has lots of shoots at the base. Answer:  Wait for the first frosts to blacken the leaves of the cannas then lift them. Cut off all the dying growth and remove as much soil from around the roots as possible. Leave them upside down somewhere cool and dry until totally dry. Once dry knock off any remaining soil, ensure that the rhizomes are hard and firm then store over winter in a cool, dry place. They can be replanted again once the ground has warmed up in the Spring. I see you live in Essex. As it is warmer down there then they may be OK in the ground overwinter but they need to be covered with a protective layer of straw. The drawback is that flowering may be late and/or poor next year. If you have Dahlias you should follow the same procedure.
