Disease and your
Disease and your Peach Tree
(continued - page 5)
Individual peaches need to be exposed to the sun if they are to
ripen successfully. With this in mind, lightly prune any foliage which
is clearly preventing light from reaching shaded peaches.
Knowing when the fruit is ripe can be judged from it's colour. If in doubt,
gently press the fruit at the stalk end. If it 'gives' a little, the
fruit is ripe - if it is hard, leave it for a week or so.
Ripe peaches do not keep for any length of time and they should be eaten
within a day or so of harvesting.
Diseases and Pests
The most important preventable pest for peach trees is peach leaf
curl. The fungus 'Taphrina deformans', which is responsible for the disease,
over-winters in cracks in the bark. When the young leaves expand, the
fungus attacks them and results in severely deformed leaves. The flowers
and fruit drop. Note that when the leaves have expanded to their full size, they can no longer be infected.
To the left 'Peach Leaf Curl'
The cure for peach leaf curl is to spray the entire tree towards
with Bordeaux Mixture - this is readily available in most garden
centres. Follow the instructions carefully for best effect. Repeat the
. In this way, the fungus will be killed before
the leaves expand.
What To Do If Peach leaf Curl Strikes?
Peach leaf curl is bad for for peach trees because it causes the
leaves to become infected and fall off. This puts the tree under great
stress and can sometimes kill the tree. Often though the tree
partially recovers and leaves begin to grow again in a month or so,
not as good as before but they can grow. These new leaves will NOT
become infected this season, whatever state the peach tree is in, so
do not remove them because they are providing energy to a stressed
The first thing to do is to remove all fruit from the tree. They will
never develop fully after an attack of peach leaf curl so don't let
the tree put any energy into them. Don't over-water but do provide
water if the conditions become dry. Apply a nitrogen rich fertiliser
around the base of the tree and water in well.
Then cross your fingers, wait for next year and hope!
Which Peach Tree To Buy
The best type of peach tree is a one year old tree. If bought any
older, ensure that it has been pruned correctly for a fan-trained tree.
There is a limited range of peach tree varieties which are suitable for
outdoor growing as a fan-trained tree. The best is 'Peregrine' - it
produces peaches with an excellent colour and taste, crops each year and
is suited for fan-training.
Do not be tempted to buy a nectarine tree! Although a type of peach tree,
they are less hardy than peaches and more likely to suffer from diseases.

Message: In Devon UK, I have a wonderful Nectarine. Wall-trained. Cover it every November with a polythene tent, which I leave on until May/June. Never had peach curl since. Every year the most wonderful juicy Nectarines. So I don't agree with the advice not to bother. Might be harder in northern climes.

Message: Big green tomatoe worm, Get rid of these using any household multipurpose cleaner(spic and span or lysol, Mr. clean). Mix cleaner with water about a 10 to 1 concentration(1T cleaner to 10T water,ie). Spray the plant and the next day they should be dead then remove worms stuck to leaves, as some may remain on leaf dead.
