How do you winterize lilac bushes?
To help prevent winter heave (exposure of roots due to the ground freezing and thawing), cover the base of the plant with 3 to 4 inches of mulch. During late winter or early spring, if a harsh freeze comes along, you may need to cover your shrub to protect the new buds. You can use a blanket, plastic tent, or burlap.
