How to prune lavender after flowering

Recognise the right kind of cut

Lavender does not benefit from the same heavy pruning at every time of year. After the main flowers have faded, a light summer trim usually means removing spent flower stems and a modest amount of leafy growth. In a region with cold winters, a hard late-season cut may encourage tender regrowth that is vulnerable to frost. Consider the age and vigour of the individual plant and the local weather before choosing how much to remove.

Keep living growth on every stem

Look for the transition between leafy green shoots and the older, woody framework. Many established lavender plants do not reshoot reliably from completely bare, old wood. Keep a visible portion of healthy green growth rather than trimming all stems down to the brown base. Where a plant has already become very woody and open, removing most of its branches at once is risky; gradual correction or replacing a very old plant may be a more realistic plan.

Separate summer tidying from spring shaping

The light cut after flowering is not the same as the shaping cut many gardeners make in spring once serious frost has passed. In spring, inspect which shoots survived winter and how the plant is growing before bringing it into a rounded form. Different lavender species and hybrids may differ in growth habit and winter tolerance, so do not assume the same calendar date suits every cultivar or climate.

Care after pruning

Work with clean, sharp secateurs and choose a dry day when possible. Avoid prolonged wet soil around the roots and resist the temptation to compensate for pruning with heavy fertiliser. Watch for yellowing, soft shoots and damaged stems over the following weeks. Record when you cut and how the plant responded; that observation is more useful for next year than copying an exact date from another region.

Before you begin: three practical checks

• Check that flowering has largely finished
• Leave green, leafy growth on cut stems
• Use the following spring to assess winter damage
