Rejuvenating Woody, Overgrown Lavender
Has your once-bushy lavender become woody, leggy, or sparse—more twigs than flowers? Don’t give up! Even tired, overgrown lavender can often be brought back to bloom with some strategic, careful pruning (and a little patience). Here’s how to revive mature lavender plants and enjoy thick, scented growth again.
Why Lavender Gets Woody
- Lavender blooms on new growth. Without annual pruning, stems go woody and leafless at the base.
- Age: Many lavenders grow woody with time—often after 5–8 years without regular, hard pruning.
- Overcrowding: Tight plantings can shade lower stems, hastening woodiness.
- Poor pruning habits: Trimming only the tips won’t stimulate new, bushy shoots at the base.
Can You Save Woody Lavender?
- Early-stage woodiness: Yes! Hard pruning can stimulate new shoots if some green growth remains on stems.
- Extremely woody, leafless plants: Sometimes it’s best to replace with new plants or cuttings.
Rejuvenating Woody Lavender: Step-by-Step
- Assess the Plant
- Check for living, green growth low on stems. If some remains, you can try rejuvenation.
- If only the very tips are green (or all stems are brown/grey), it’s often “end of life” for the plant.
- Prune in Early Spring (or Just After Bloom)
- Using clean, sharp shears, cut back about one-third of the plant’s height.
- Always leave several inches of green growth—never prune into brown, leafless wood.
- Shape into a Dome
- Prune for a rounded, mound shape to encourage even, bushy regrowth from all sides.
- (Optional) Do a 2-Stage Hard Prune
- For very old plants: Prune back half of the woody stems each spring over two years, never removing all the green at once.
- Feed and Mulch
- Top-dress the base with compost or sharp sand—not bark mulch—to encourage vigor and drainage.
- Water Wisely
- Water if dry, but avoid soggy soil—root rot is the enemy of recovery.
Don’t Forget: Try Propagation from Old Plants
- Take non-flowering stem cuttings from surviving green tips (see our cuttings article). Planting new lavender ensures lush, compact plants for years to come.
Pro Tips
- Continue annual post-bloom pruning in future to keep new growth coming and prevent repeat woodiness.
- If the plant doesn’t green up after two seasons, it’s time to replant.
Wrapping Up
Even years-old, woody lavender can spring back to life with strategic pruning, patience, and good aftercare. Give your plants one last chance before replacing—your lavender hedge or borders may be bursting with blooms again within a season!
