Rooting Lilac Cuttings in Colorado: Low Success, Better Alternatives

Why Lilac Cuttings Are Notoriously Difficult

Lilacs (Syringa) root poorly from cuttings. If attempting:

• Use bottom heat (propagation mat).
• Take semi-hardwood cuttings (not soft, not woody) in early summer.
• Cut at slant; dip in rooting hormone.
• High humidity (mist or dome).

Better Method: Layering (Do in Autumn)

1. Bend low branch to ground.
2. Wound underside, dust with hormone.
3. Cover with peat moss; secure.
4. Leave all winter. Spring = rooted new plant.

If Cuttings Failed

Try layering next fall. Or buy a container-grown plant suited to your zone.
