Winter
Water Garden: Remove the worst of the autumn
leaves as they fall into the pond – a lightweight net such as a fruit cage
net will keep out the worst of them. Float a couple of tennis balls on the
water as this will help absorb the pressure from the ice during the frosty weather.
The Lawn: Remove any leaves that have accumulated
as they kill off the lawn below leaving ugly yellow or brown patches.
In warm, damp weather keep an eye out for fungal diseases such as red thread
(yellow patches with red threads up to one inch long) and dollar spot
(small round yellow / brown spots the size of a coin). If you find any disease,
treat it with a fungicide.
The Rose: Prune hybrid tea shrub branches
back by 1/2 to 1/3 to reduce wind rock and firm soil at the neck.
Ornamental Trees: Continue regular clipping of
topiary.
Knock off any snow that falls on shrubs as when it melts it may break the
branches.
Remove any dead wood and crossing stems or weak forks.
Our last update on Sudden Oak Death remains unchanged. Please keep a sharp
look out for the disease as it is not only affecting oak trees: it is also
affecting rhododendrons and viburnums throughout England.
It is caused by Phytophthora ramorum
and mature trees wilt and die within months following infection.
Symptoms are branches dieing back from the tips, very often in a short time,
ending in the death of the plant. Remove the plant and burn it on site
as soon as possible. Do not take it to other gardens / nurseries for
identification.
If the presence of the disease is suspected on these species
contact DEFRA Plant Health and Seeds Inspectorate,
tel: 0190 445 5174; for oaks contact the
Forestry Commission Plant Health Service,
tel: 0845 367 3787.

Ornamental Shrubs: Remove suckers from grafted
plants and prune out reverted shoots on variegated species. Carry our formative
training and pruning. Knock off any snow that falls on shrubs as when it melts
it may break the branches.
