Because many homeowners are tending to their summer gardens by weeding, feeding and cutting blooms for their vases, we've had a lot of questions from customers as well as friends about pruning. Should they cut back - prune - their flowering shrubs like hydrangeas or rose-of-Sharon?
Now? Later? Ever?
Should I prune?
Because flowering shrubs generally thrive year after year without much attention, many homeowners don't consider pruning until they're overgrown and interfering in some way. But pruning promotes the growth of the shrub and helps you maintain the size and shape you want for the plant. Also, when you take just a few minutes each year to prune, you'll see an increase in the number of blooms during flowering season. And isn't that the reason we plant shrubs to being with? Anyone can prune and annual pruning should take less than ten minutes for each shrub.
When do I prune?
The ideal time to prune is determined by when the shrub forms its flower buds and when those buds open. Flowering shrubs are either spring-blooming plants or summer-blooming plants.
Spring-blooming shrubs (think lilac) develop flower buds in summer that don't actually open until the following year's spring. Prune these immediately after flowering, because if you prune too late you'll risk removing some (of all!) of those buds for next year.
Summer-flowering shrubs, like rose-of-Sharon and hydrangea, develop buds in the spring that bloom into flowers that summer. These shrubs should be pruned in late winter or early spring, before the buds begin to show.
What are my goals?
Before you start cutting away with those pruning shears, think of what your goal is. Your intent with pruning flowering shrubs should be to maintain the health of the plant and to enhance its natural form and beauty - its shape, size and flowers - by selectively pruning branches. Remove dead and damaged branches and prune branches that are getting intertwined with each other. Be sure to cut back to the ground (or a live bud or branch if there is one).
It shouldn't be terribly obvious that you just cut your shrubs. In fact, when done really well, maintenance pruning isn't apparent at all but you will preserve the health of your shrubs and see more flowers next season!
