How to Prune Lavender: A Simple, Correct Guide
Pruning lavender is essential if you want compact plants, lots of flowers, and a long lifespan. Lavender that isn’t pruned regularly quickly becomes woody, sparse, and short-lived. The good news is that pruning lavender is easy once you know when to prune, how much to cut back, and where to stop.
This guide explains how to prune lavender properly, suitable for English, French, and hybrid lavenders.
Why Pruning Lavender Is Important
Regular pruning helps lavender to:
- Stay compact and bushy
- Produce more flowers
- Prevent woody, bare centres
- Improve airflow
- Live longer (often years longer)
Unpruned lavender usually flowers less and declines quickly.
When to Prune Lavender
Lavender is usually pruned twice a year.
1. After Flowering (Main Prune – Late Summer)
This is the most important prune.
- Timing: After the main flush of flowers finishes
- Purpose: Shape the plant and encourage fresh growth
2. Spring Tidy (Light Prune)
A gentle clean-up.
- Timing: Early to mid-spring once new growth appears
- Purpose: Remove winter damage and refine shape
❌ Avoid heavy pruning in autumn or winter.
How to Prune Lavender After Flowering
This is the key pruning session.
Step-by-Step
- Use clean, sharp secateurs
- Remove all spent flower stems
- Cut back around one-third of the plant’s height
- Shape the plant into a neat mound
- Always leave green growth visible
Never cut into hard, woody stems with no leaves.
How to Prune Lavender in Spring
Spring pruning is lighter and more cautious.
What to Remove
- Dead stems
- Frost-damaged growth
- Straggly or uneven shoots
Trim lightly, stopping as soon as you reach healthy green growth.
How Much Can You Cut Back Lavender?
Follow these two rules:
- Never remove more than one-third of the plant at one time
- Never cut below green growth
Lavender does not reliably regrow from bare, woody stems.
Where to Cut Lavender
Always cut:
- Just above a leaf joint
- Above visible green growth
Avoid cutting:

This builds a strong, compact plant shape.
Common Pruning Mistakes to Avoid
