Pruning and Dividing Lavender After Bloom

For a large, bloomed-out lavender plant (Zone 5–8), here's the post-flower routine.

Pruning

• After flowers fade: Shear back to 2″ above the woody base. Do not cut into old wood—it won't resprout.
• In subtropical zones (9+), light shaping only.

Division (Propagation)

1. Dig the entire plant in early fall or spring.
2. Use a sharp spade to split the root ball into clumps, each with roots and shoots.
3. Replant immediately in gritty, well-drained soil.
4. Water weekly until established.

Key Point

Lavender hates wet feet. Sharp drainage (sand/grit) is more important than fertilizer.

Annual shearing keeps it compact and floriferous; division every 3–4 years rejuvenates woody centers.
