Rowan Tree

The Rowan or Sorbus sargentiana is a slow-growing tree with large, sticky red buds in autumn. In spring, dark green leaves are produced which turn a fiery orange and red in autumn. The white flowers are produced in early summer usually followed by red berries which are quickly eaten by birds.

We have cabbage whitefly

The symptoms to look out for are white-winged insects about 1.5mm long which fly up in clouds from the underside of brassica leaves when disturbed, flat, oval, whitish-green scale-like nymphs are attached to the lower leaf surface and black or greenish-grey sooty moulds can develop on the upper leaf surface on the sticky honeydew excreted by this pest.
