Apr 02, Knowing when to trim lilac bushes is important.
Most lilacs don’t require pruning until they reach about 6 to 8 feet ( m.) tall. The best time for pruning lilac bushes is right after their flowering has ceased. This allows new shoots plenty of time to develop the next season of blooms. Pruning lilacs too late can kill young developing buds.
I cut off all the flower clusters when they fade on my very young bushes, so they use energy on growing, not seeds. Lilac bushes SHOULD be cut, they are FOR being enjoyed where you want them in vases or being given away. Church flowers, nursing home friends, spread the flowers around!
I get so many good memories of things, when I sniff smelly lilacs!! Feb 10, Home gardeners can choose between two different pruning methods. 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 severe pruning will induce a large number of shoots to develop during the growing season.
Jul 08, Although you'll be losing some flowers for the current year, pruning overgrown lilacs is easiest early in the spring before the branches leaf out. After three consecutive years of pruning your overgrown lilac in this way, new shoots should comprise the bulk of the plant.
You should clip flowers off immediately after they fade, but even if it slipped your mind last year, some careful pruning can get you back on track for spring. Ideal Lilac Pruning.
