How to Revive an Old, Neglected Lilac
Lilacs are a beautiful, fragrant flower that can be used to add color and life to any garden or yard space. But when they become old and neglected, they can start to look a bit drab and uninteresting. Fortunately, old, neglected lilacs can be renewed or rejuvenated by pruning.
What is a Lilac?
A lilac is a flowering shrub or small tree that belongs to the genus Syringa in the olive family (Oleaceae). They are native to Europe, Asia, and North America and typically produce an abundance of fragrant purple or white flowers in the springtime.
Factors Affecting Lilac Growth
The growth of a lilac depends on several factors such as soil type, soil pH, moisture levels, light exposure, and pest infestation.
Pruning Techniques for Renewing Old Lilacs
Home gardeners have two different pruning techniques available for renewing an old lilac: cutting back the entire plant or pruning only the stems that need it.
Cutting Back the Entire Plant
One way to renew a large, overgrown lilac is to cut the entire plant back to within 6 to 8 inches of the ground in late winter (March or early April). This will encourage new growth and help revive the plant.
Pruning Only What’s Needed
Alternatively, you can selectively prune only those stems that need it by removing any dead wood or thinning out overly dense clusters of branches.
