How to Propagate Lilacs from Cuttings: A Simple Guide

Propagating Lilacs from Softwood Cuttings

The easiest way to multiply lilacs is by taking softwood cuttings in late spring or early summer. Follow these steps:

1. Cut a tender shoot at least 6 inches long.
2. Remove lower leaves, leaving 2–3 sets at the top.
3. Dip the cut end in rooting hormone (available at garden centers).
4. Insert 1 inch deep into moist potting mix.
5. Cover the pot with clear plastic to maintain humidity.
6. Place in indirect light (east window or under fluorescent lights).
7. After 2 weeks, check for roots by gently tugging. Resistance means roots have formed.
8. Remove plastic, keep soil moist, and treat as a seedling.

This method works for many shrubs. Good luck!
