There are two options when pruning a plum tree. The first is shape and the second is infection (silver leaf disease). You can avoid silver leaf disease by pruning plum trees during the correct season, June. During the summer, the temperature allows the tree to grow stronger so do not prune in winter. Make the pruning cuts as clean as possible, and avoid damaging the wood. Note – Burn any diseased or dead wood.
The design of plum tree pruning depends on what you want – pyramid, bush, standard or half standard. Pyramid trees are pruned in a different way from the other forms.
