Divide suckers from the base of mature lilac plants
Dig up rooted suckers carefully
Separate them from the parent plant with roots attached
Replant suckers immediately in prepared soil
Layer a low branch by bending it to the ground
Wound the buried section lightly
Cover the section with soil and secure it in place
Keep the layered section moist until roots form
Cut the new plant from the parent after rooting
Grow lilacs from seed only if you want to experiment
Collect seeds from mature pods
