Why won't my plum tree produce plums? One of the most common causes of plum tree problems is the lack of a co-pollinator. Plums are not self-fruitful and need another of the same species nearby for pollen transfer. This is done with bees, moths, and other pollinator's help. Pruning at the wrong time removes the buds necessary for flower and then fruit.
When should I prune my plum tree?
When to prune plums
Avoid pruning plums in winter, as it increases the risk of infection by silver leaf disease to which plums and other Prunus species are prone. The best time for pruning is usually spring for young trees and mid-summer for established ones.
Can I take a cutting from a plum tree?
A plum tree grows best from a hardwood cutting taken in late autumn or winter from two-year-old growth. Avoid taking a cutting from weak offshoots or suckers sprouting from the tree's roots and cuttings from a hyper-vigorous branch that is much longer than the surrounding growth.
