Whether you’re starting a garden or expanding your herbal collection, lavender brings timeless charm and practical benefits to every outdoor space.
TL;DR
- Regular pruning is essential for lavender's health, shape, and longevity.
- Unpruned lavender can become leggy and have a shorter lifespan.
- The primary pruning should occur in late summer to encourage new foliage growth for winter protection.
- A light trim may be needed in late spring after the risk of cold weather has passed.
- If tidying in autumn, complete pruning by mid-October, removing old flower stems and trimming about 2cm of green growth.
- Avoid cutting into old, bare wood as lavender typically won't regrow from it.
- Ensure some healthy green growth remains for regeneration.
- Avoid pruning in October if frost is imminent, as fresh cuts are vulnerable.
- Pruning once a year can extend lavender's life to over twenty years.
