How to Grow Lavender in a UK Garden or Allotment

Lavender grows best in the UK in a sunny, sheltered spot with free draining, slightly alkaline soil, and it actively dislikes rich, damp ground or heavy shade. Plant it in spring once the last frost has passed, keep it on the lean side rather than feeding it heavily, and prune it firmly each year straight after flowering to stop it going woody and bare in the middle.

Lavender is the plant my whole allotment story really started with, so I have learned this one the hard way, through several plants that sulked before I understood what they actually wanted.

Choosing the right spot

Lavender is a Mediterranean plant at heart, so it wants sun, drainage and a little bit of neglect. Full sun for most of the day, soil on the poorer side rather than rich compost, and good drainage matter far more than feeding or fussing. If your soil is heavy clay, raising the bed slightly or working in grit before planting makes a real difference.

Planting and early care

Spring, once the frost risk has passed, is the safest time to plant young lavender in the UK. Water it in well to help it establish, then largely leave it alone. Established lavender is genuinely drought tolerant, and overwatering is a far more common killer than underwatering.

Pruning, the step people skip

This is the one that determines whether your lavender lasts two years or ten. Prune firmly straight after flowering each year, cutting back the fresh green growth but stopping short of cutting into old bare wood, which lavender generally will not regrow from. Skip this step for a couple of years and you end up with a leggy, woody plant with flowers only at the very tips.

Winter care in the UK

Most English lavender varieties handle a UK winter perfectly well outdoors, provided drainage is good, since it is wet roots rather than cold air that tends to cause losses. Avoid mulching too close to the base with anything that traps moisture against the stem.

Why I grow it myself rather than buying it in

Everything I harvest from my own lavender feeds directly into what I make. It appears as dried botanicals in my fragrance free range and, separately, essential oil is what scents my lavender bar in the essential oil range. Growing it myself means I know exactly how it was tended, right from a bed on my own allotment.

Frequently asked questions

What is the best soil for growing lavender in the UK?

Free draining, slightly alkaline soil on the lean side, rather than rich or heavily fed ground.

When should I prune my lavender plant?

Straight after flowering, each year, cutting back the green growth without cutting into old woody stems.

Does lavender survive UK winters outdoors?

Yes, most hardy English varieties do well outdoors through a UK winter provided the soil drains freely and the roots are not sitting wet.
