White Native Azaleas: Azaleas and rhododendrons bloom on old wood, so prune them within three weeks after blooming and apply acid-loving plant fertilizer for optimal flowering.
Camelias: Prune camelias after they finish flowering, as they also bloom on old wood; early pruning can remove flower buds.
Spring-Blooming Clematis: Spring-blooming clematis, like 'Francis Rivis,' should be pruned after flowering to avoid cutting off flower buds.
Flowering Quince: Prune flowering quince after flowering to encourage more profuse blooming the following spring.
Forsythia: Prune forsythia after flowering to avoid clipping away flower buds and reducing blooming.
Lilacs: Prune lilacs in late spring after flowering to rejuvenate the shrubs without removing flower buds.
Spring-Flowering Spirea: Prune spring-blooming spirea only when flowering is finished, as they bloom on old wood.
Honeysuckle: Prune honeysuckle vines lightly at any time but avoid heavy pruning when they bloom in spring; instead, prune after flowering or in winter dormancy.
