Planting and Growing Lavender

Plant outside in late spring, in a sheltered, but open sunny position. Best grown in a good, free draining sandy soil. Avoid excessive wet soil in winter. Needs full sun to flower well. Extremely drought tolerant once established.

Ideal for bringing a touch of the Mediterranean to your garden. Lavender is good for both formal or informal use. Plant it individually, as border edging or as a low hedge. It can be grown around beds, borders or paths, to divide up parts of your garden or to make a traditional parterre or knot garden. For hedges, space plants 12in (30cm) apart.

Dwarf forms (especially French lavenders) are great for pots and patio containers, where you can appreciate the flowers and fragrance up close. The grey-green foliage emits an attractive scent when brushed past and the flowers are highly attractive to pollinating insects.

A small vase of lavender flowers will bring a rich aromatic scent into any room, even after the flowers have gone over. Superb for cutting and drying for winter use. The dried flowers are a useful ingredient in potpourri and potpourri bags.

Taking Care of Lavender

Water well until established. Mulch with organic matter in spring and apply a high potash fertilizer suitable for shrubs.

Dead head after flowering to keep tidy and prevent self-seeding.

Pruning Lavender

Prune twice a year. Remove the old flowering shoots after flowering, then trim back lightly in the autumn or spring, removing about 1in (2.5cm) of growth. Do not cut back into old wood.

If a plant becomes tall and leggy (usually through lack of pruning), and replace the mother plant with it once it roots and reaches suitable maturity.

Drying Lavender

For drying, pick flower stalks just as they begin to open. Suspend in tied bunches upside down in a dry, dark, airy room.

Pests and Diseases

Susceptible to attack by Cuckoo spit (froghoppers) and rosemary beetle.

The leaves can be affected by grey mould.

Propagating Lavender

Sow seed as soon as it is ripe in autumn. Note: cultivars may not come true from seed.

Lavender strikes readily from semi-ripe cuttings taken in spring or summer. Alternatively, take stem or heal cuttings in autumn, overwinter in a cold frame and plant out the following in spring.

Then can also by increased by layering a low lying branch or stem but this can take several years to produce results.
