CONVENTIONAL wisdom says we prune trees and shrubs in autumn and winter when they are dormant, but there are several varieties that ought to have a haircut in summer.
These largely fall into two categories; those that are susceptible to silver leaf disease; and shrubs that flower in early summer and create each year’s blooms on strong young growth produced the previous year and early the next.
A third group are evergreen shrubs that are less hardy can be damaged by cold if trimmed in winter.
This week I have been busy pruning our recently flowered philadelphus and weigela, giving a straggly ornamental flowering cherry a much needed tidy up, and pruning our plum and greengage trees.
I also checked over variegated euonymus and found a small case of reversion, where the green-and-white leaves had been replaced by solid green foliage. This needs to be pruned out otherwise it will eventually take over the whole plant.
