The general rule for pruning summer and spring flowering shrubs and trees is to prune while the plants are dormant in winter. You can also opt to prune right after the trees and shrubs flowers fade.

For flowering plants, it is best to prune after they have finished blooming. Sometimes if you prune them in winter you can remove the buds and significantly decrease your spring bloom. Early bloomers that benefit from the method of pruning just after they finish flowering include lilac, forsythia and rhododendron.

Plants that are better to prune in the winter months include potentilla, butterfly bush, and crape myrtle. This is because they bloom from new growth rather than existing; pruning when they are dormant will ensure that growth is fresh and strong in time for the summer months.

Plants including hydrangeas, roses, and clematis can be confusing because they flower at multiple times during the year, so they have a completely different set of rules. Hydrangeas bloom from old wood and are best to be pruned early in summer.

Don’t prune young trees for a year until they become established.

Annual flowers and plants
