One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease,but it is a wound that will heal.Often there is a race between the healing and the disease as to whether the tree will live or die,so that there is a period when the tree is at risk.It should be the aim of every gardener to reduce that risk of death as far as possible.It is essential to make the area which has been pruned smooth and clean,for healing will be slowed down by roughness.You should allow the cut surface to dry for a few hours and then paint it with one of the substances available from garden shops produced especially for this purpose.Pruning is usually done in winter,for then you can see the shape of the tree clearly without interference from the leaves and it is very unlikely that the cuts you make will bleed.If this does happen,it is,of course,impossible to paint them properly
