Pruning Spirea - Tips For Cutting Back Spirea Shrubs⚓︎
All spirea shrubs produce flowers on new wood, which is why cutting back spirea shrubs is so important. Spirea pruning not only rejuvenates the plant and encourages blooming, but it also helps to restrain the size of the shrub. Pruning spirea after a couple of years will rejuvenate the plant.
In the spring, after the first blooms are spent, cut the dead flowers back by trimming spirea’s stem tips back to the topmost leaf on each stem.
Throughout the summer, the plants shape can be maintained by cutting back overgrown spirea shoots or stems as well as any dead or diseased branches. Try to make the cuts within ¼ inch (6 mm.) of a leaf or bud.
Fall is the time for the most severe pruning of spirea. With sharp shears, cut each stem back to about 8 inches (20 cm.) from the ground. Don’t worry that the plant won’t bounce back. In the spring, spirea will reward you’re courageous pruning with new stems and plenty of blossoms.
