In late summer, clip the plants back lightly after the flowers have faded. Cut the stems back by a few inches, but not so far that the stems are bare of live foliage, and plants will then have time to produce new shoots before winter dormancy.
This drought-tolerant plant thrives in a sunny border, container, herb or gravel gardens.
Best planted between April and May when the soil is warming up, lavender thrives in most free-draining soils in full sun. Heavier soils should have some grit added to improve drainage and to open them up.
Space plants 90cm (3ft) apart, or if growing a hedge, 30cm (1ft) apart or, 45cm (18in) for larger cultivars.
Lavender can be grown in large pots, 30-40cm (1ft-16in) diameter, using a multipurpose or loam-based compost such as JI No 3, with some extra coarse grit, (up to 30%), to improve drainage, along with some controlled release fertiliser granules.
Ensure that the compost is regularly watered in summer, although for improved cold tolerance, kept on the dry side during winter by standing in a cold greenhouse or in the rain shadow of walls.
