How do you winterize lilacs?

Last Updated: 13th September, 2021

Use 3 to 4 inches of organic mulch, like shredded leaves or bark, around the base of your lilac to prevent winter heave, the exposure of roots due to the ground freezing and thawing. Lilacs over the age of seven generally don't have a problem with winter heave due to their deep roots.

Is it OK to trim bushes in the fall?

Cut back shrubs grown primarily for their foliage, such as barberry and burning bush, almost anytime except in late autumn. New growth that starts after late-season pruning won't harden off properly before winter. If you want to do major pruning, it's best to cut the shrub back when it is dormant in winter.

Why did my lilacs turn white?

If you see white powder on lilac leaves, it doesn't mean your bush is at the end, but unless you correct the underlying cause, it can become a chronic condition that weakens your bush over time. Powdery mildew on lilac bushes isn't caused by a single fungus, but is, instead, caused by several different species.
