Lavender is a Mediterranean evergreen shrub, grown for its fragrant leaves and bee-friendly flowers. There are hardy, half-hardy and tender species of lavender to choose from.

Lavenders work in a variety of situations, from wildlife gardens to cottage gardens and even formal gardens, such as planted beneath shrub roses or used as a low-growing lavender hedge. Many lavenders thrive in pots.

Choosing lavenders to grow

The type of lavender you grow will depend on personal choice, including flower colour and shape, plus the shade and fragrance of the foliage (some lavenders have silvery grey leaves, while others are more green). However, there are some pointers to be mindful of when choosing which lavender to grow in your garden. Firstly, it's worth noting that English lavender, Lavandula angustifolia, is more hardy and long-lived than French and Spanish lavenders, Lavandula dentata and Lavandula stoechas. It's thought that English lavender is also more attractive to bees than French or Spanish lavender.

Traditional English lavender varieties include 'Hidcote' and Lavandula 'Munstead'. These are undeniably lovely and rightly popular, but have you considered intermediate lavenders? Sometimes called 'lavendins', these hybrid lavenders have Lavandula angustifolia and Lavandula latifolia as their parents. Lavendin lavenders are more robust than other lavenders and therefore more tolerant of wetter soils and colder winters. They're larger in habit than English lavenders and flower for a longer period, providing more flowers for you to enjoy and more pollen and nectar for bees. Popular hybrid lavenders, or lavendins, include Lavandula x intermedia 'Edelweiss' and Lavandula x intermedia 'Grosso'.

How to grow lavender

Grow lavender in full sun in well-drained soil. Half hardy and tender lavenders, such as Lavendula stoechas, should be grown in a sheltered spot. Cut back after flowering to prevent stems becoming woody.

Lavenders thrive in an open site in full sun in a well-drained, neutral to alkaline soil (got acid soil? Try French lavender, Lavandula stoechas, instead). They cope well with drought conditions and may suffer in wet, heavy soils, particularly over winter.

Half-hardy and tender lavenders, such as Lavandula stoechas, are best grown in pots so that they can be moved to a light, airy frost-free spot for winter.

The best time to plant tender lavender is in spring, from March through to May. If you have heavy soil, improve drainage by adding horticultural grit to the planting hole before planting. Planting on a slight mound can also help prevent water-logging. Plant lavender at the same depth it was in its pot. Add a sprinkling of bonemeal to the planting hole, place the plant in the hole, backfill and firm in. Water well.

When planting lavender in pots, choose terracotta pots with drainage holes. Fill with a John Innes no. 2 or 3 and mix in some horticultural grit, for drainage. Pots should be placed in a sunny spot away from overhanging trees and shrubs.

How to care for lavender plants

Hardy lavenders (Lavandula angustifolia and Lavandula x intermedia types) can cope with temperatures down to about -15°C, and can therefore be left in the garden all year round. Prune after flowering, typically in August. Cut back quite hard but don't cut into old wood, as this can reduce flowering potential the following year. Be careful not to remove green shoots as this can kill the plant.

Half-hardy lavenders, such as Lavandula stoechas, flower for a long season but may not survive winter. Prune after their first flush of flowers have faded but avoid pruning any later than early September.

If growing the more tender lavenders, such as Lavandula denata, deadhead and prune only if the plants become scruffy.

In this short video guide, Monty Don demonstrates how to cut back lavender after flowering, to maintain a neat, compact shape and prevent it becoming leggy and unkempt:

How long does lavender live?

Lavenders are not long-lived plants. Expect tender varieties to live for about five years. If pruned correctly, hardy types can live for about 15 years (as many as 20 years, in some cases).

Take semi-ripe lavender cuttings in late summer. Remove non-flowering shoots, about 10cm long, with a woody base and a tip with new growth. Pull off some of the lower leaves. Fill plastic pots with peat-free multi-purpose compost, water and then push the cuttings into the compost. About 1cm should be below the soil. Cover pots with a clear plastic bag and place in a light and airy place. A greenhouse is ideal.

Growing lavender: problem solving

What to prune in autumn - pruning lavender
How to grow lavender - pruning lavender

Lavender can be become very leggy and bear few flowers. The reason for this is lack of or poor pruning. Many gardeners just deadhead hardy types which leads to leggy plants and few flowers. Looked after in this way the plant will be very short lived.

To rejuvenate a woody plant, prune in mid-August to just above a green shoot and hope for the best. If new shoots don’t appear within the next month you might be better off starting again.

Frequently asked questions

How do you grow lavender from posti plugs/mini plug plants?

Plug plants need to be grown on before they are transplanted into the garden. When they arrive, water the plugs and allow them to acclimatise in a light, warm place for 24 hours. Then they can be potted up, watered and grown on in frost-free conditions. Harden off and plant out when they are large enough to thrive outside.  

When is the best time to move lavender plants?

Spring is a good time to transplant young lavender plants as the soil is warming but plants are not yet in flower. Plants that have been moved will need to be watered and the area around them kept free of weeds.
