Lavender is a stalwart of the classic cottage garden, but it fits all styles, from Mediterranean gravel spaces to chic urban courtyards. It has a long flowering period, from around June to September, and the fragrant foliage keeps its colour year-round, even when the plant is dormant over winter.

When should I plant a lavender hedge?
Although the autumn and winter months are a good time to start planning your lavender hedges and thinking about what sort of plants you want to include in your design, you need to wait until the soil has warmed up before you can plant them. In the UK, this can be any time from mid-April until the end of July. If it is a cold spring, it's best to wait to plant until May. Lavender roots will grow much more quickly in warm soil.
What sort of lavender should I choose?
English lavender is the most robust and long-lived. This hardy perennial has tiny flowers on grey/green stems. French lavender, which has tufty top petals, which look like a butterfly’s wings, is less hardy, so unless your chosen spot for a hedge is extremely sheltered, it is best to go for an English variety.
There are more than 250 English lavenders, and these include dwarf plants, which won’t grow taller than 30cm. ‘Little Lottie’ and ‘Miss Muffet’ are two examples. Larger, bushier choices for bigger gardens include Lavendula Intermedia ‘Grosso’ which tops 1m in height and spread. Lavenders don’t just come in blue. Go for white, misty purple or even pink!
Where should I plant a lavender hedge?
Good drainage is the key to success with lavender. It will not thrive in damp or heavy, soggy soil so a well-drained site is a must. Choose a sunny spot and your lavender hedge should thrive in the right conditions.
How to plant a lavender hedge
1. Fork over the soil in the area where you want to create the hedge. Space the plants about 30cm apart (or 45cm for larger species, check the plant label for height and spread). If the soil is heavy, incorporate plenty of grit before planting.
2. Dig a hole which is just a bit larger than the plant’s root ball.
3. Take the plant out of its pot and place in the soil. Fill the gap, and then firm around the base.
4. Water in thoroughly, aiming for the roots, not the foliage. After planting, keep watered regularly in dry weather for the first growing season. After that, it should look after itself. Usually, lavender does not need feeding. You could do it just occasionally using an all-purpose feed to improve the overall health of the plants, but it is not essential.
When should I prune a lavender hedge?
English lavender should be pruned twice a year to keep the hedge bushy and compact. This will stop leggy brown stems appearing. When the flowers have faded in late summer or early autumn, trim them off. Then cut about 2.5cm from the plant’s leaves, making sure that some green stays on. This lets light into the plant and enables new shoots to form before the lavender becomes dormant over winter. In late February or in early March if it has been a cold month, trim the lavender plants lightly again using a pair of sharp garden shears.
