Can lilacs be cut back to the ground?

How do you rejuvenate a lilac bush to get more flowers?

How do you revive a lilac bush?

When to cut back Lilacs for Rejuvenation?
Lilac Rejuvenation. Cutting the entire plant back to within 6 to 12 inches of the ground as new growth begins in late winter prompts mature lilacs to send up many new shoots.

How tall should a lilac tree be before you cut it down?
