Lavender is a much-loved evergreen shrub, valued for fragrant summer flowers, silver-grey foliage and its appeal to bees. English lavenders, including 'Hidcote' and 'Munstead', are reliably hardy across the UK, whereas French types need greater winter shelter.

When and how to sow

Buy young plants in spring, once severe frosts have passed, or take softwood cuttings in early summer; seed is slow and variable. Set English lavender 45 to 60 cm apart in full sun, using light, free-draining soil. Improve heavy ground with horticultural grit and plant on a slight rise. It suits gravel gardens, border edges, low hedges and generous pots.

Care

Water newly planted lavender during prolonged dry spells in its first summer, then sparingly. Keep the crown clear of wet organic mulch and use gravel instead. Trim off faded flower stems and lightly shape leafy growth after flowering. Never cut into old, bare wood, as it may not reshoot.

Common problems

Winter wet and poorly drained soil are lavender's principal enemies, causing yellowing, dieback and root loss. Give plants sun, space and gritty drainage, especially in colder, wetter districts. Dense, shaded growth is less floriferous and may decline from the centre. Tender lavenders benefit from a sheltered wall or greenhouse protection.

Harvest

Cut flowering stems on a dry morning when the lower buds have opened but most flowers remain fresh. Use clean secateurs and leave plenty of leafy growth behind. Display stems in arrangements or dry small bunches upside down in an airy, shaded room for long-lasting scent and colour.
