When is the best time to prune a flowering shrub?

The best time to prune a flowering shrub depends on when it blooms:

1. Spring-blooming shrubs:

* Prune immediately after flowering. This allows the shrub to put its energy into new growth and bud development for the following year.

* Examples: Azaleas, rhododendrons, lilacs, forsythia, weigela, spirea

2. Summer-blooming shrubs:

* Prune in late winter or early spring, before new growth begins. This ensures that you are removing old wood and encouraging new growth that will bear flowers.

* Examples: Rose bushes, hydrangeas, butterfly bush, crape myrtle

3. Late-summer or fall-blooming shrubs:

* Prune in late winter or early spring, before new growth begins. This allows for the maximum amount of new growth and flowers.

* Examples: Witch hazel, beautyberry, barberry, flowering quince

General Pruning Tips:

* Use sharp, clean pruning shears.

* Make clean cuts just above a bud or a set of leaves.

* Avoid pruning too deeply. Remove only dead, diseased, or crossing branches, and prune selectively for shape.

* Be aware of the shrub's specific pruning requirements. Some shrubs may need more frequent pruning than others.

Exceptions:

* Some shrubs bloom on old wood (last year's growth). These shrubs should be pruned after they bloom to avoid removing the flower buds.

* Deadheading (removing spent flowers) can encourage re-blooming. This is a good practice for some shrubs, but it is not necessary for all.

Always check the specific pruning instructions for your particular shrub variety.
