Pruning perennials

August is an excellent time to prune back tender perennials (such as blue plumbago, which is pictured) grown in home landscapes, so they will be shapelier, fuller and not so tall for the fall-blooming period.

August is a month when gardeners should think about two important aspects of landscape maintenance — fertilizing and pruning.

August is the last month in the summer growing season to fertilize hardy shrubs and ground covers in the landscape. Now is also the time to finish up pruning many shrubs, cut back overgrown tropicals and trim some bedding plants. But it’s also time to stop pruning spring-flowering trees and shrubs.
