Growing Lavender in Pots blooming year after year
Potted lavender is my absolute favourite piece for the terrace. It smells heavenly, draws in the bees and looks like a little slice of Provence in every terracotta pot – and it's wonderfully easy to care for, once you know the few rules that matter. Today I'll share everything you need so your lavender thrives, happy and full of bloom, year after year.

Caring for lavender in pots and planters: the most important basics
Lavender comes from the Mediterranean – dry, hot, stony. That explains almost everything about caring for it. It loves the sun, hates wet feet and flourishes when you simply leave it in peace. The most common mistake: watering too much. The second most common: never pruning.
1 · The right pot terracotta above all
The pot matters almost as much as the soil. Terracotta is my first choice: it breathes, draws off excess moisture beautifully and warms up in the sun. Plastic pots hold too much wet. Always make sure there is a drainage hole in the base.
2 · The right soil lean, free-draining, sandy
The right soil makes all the difference. Standard potting compost holds too much moisture – for lavender that is a death sentence. Mix two parts herb or Mediterranean soil with one part coarse sand or perlite. Garden centres also sell ready-made Mediterranean container soil.
3 · The spot as much sun as possible
Lavender on the terrace needs at least 6 hours of direct sun a day – more is better. A south-facing spot is ideal. In a shady corner lavender will put out leaves, but it will barely flower.
3b · Lavender on the terrace how to place it just right
Lavender looks loveliest on the terrace in groups: two or three pots side by side, ideally at different heights. Beside the door, around the seating corner, or as a fragrant line along the edge of the terrace.
4 · Watering less is more
The golden rule: only water once the top 3–4 cm of soil are completely dry. In summer that is usually every 5–7 days. In spring and autumn far less often. In winter: hardly at all.
5 · Feeding once a year is enough
Lavender needs very few nutrients. In a pot, a single feed in spring is enough. Choose a low-nitrogen fertiliser – a herb or Mediterranean feed works well. Too much nitrogen gives you lush leaves instead of flowers.
6 · Pruning the most important thing you can do
This is the single most important thing you can do for your lavender. After flowering, cut it back by about a third, always into the green growth – never into the woody old stems. Lavender simply will not sprout again from old wood.
7 · Overwintering easier than you think
Don't worry – overwintering lavender in a pot is far simpler than most people think. True lavender (Lavandula angustifolia) is naturally hardy. In a pot it just needs a little protection from the combination of wet and frost. I'll show you exactly how, step by step, a little further down.
8 · The best lavender varieties for pots my favourites
Not every variety of lavender is suited to a pot. My recommendations: Hidcote (compact, deep violet), Munstead (the classic, reliable English lavender), Vera (a little larger, wonderfully fragrant) and Lavandula stoechas (French lavender – gorgeous, but less frost-hardy).
Potted lavender – what to do and when
With this calendar you will never miss an important step.
- March / April · spring cut by ⅓–½, first feed, remove the fleece
- May / June · water regularly (let the soil dry out), the first flowers appear
- July · cut back after the main bloom, encourages a second flush
- August / September · enjoy the second bloom, water less
- October · stop watering, make the pot winter-ready
- November – February · winter protection, water hardly or not at all
The July cut is the step people forget most often – and the one that makes the biggest difference of all.
9 · Why is my lavender turning brown? the most common causes
Brown patches are the most common problem with potted lavender and almost always come down to one of three causes: waterlogging (root rot from too much water or poor drainage), cutting into the old wood (lavender will not re-sprout from woody stems) or – more rarely – pests.
10 · Overwintering lavender in a pot step by step
Overwintering lavender in a pot works reliably with this step-by-step method: October: cut watering right back and skip the last trim of the year (to protect the buds). November: move the pot against a sheltered, sunny wall – a south side is ideal, avoid the north wind. Wrap the pot in hessian, fleece or bubble wrap and stand it on wooden blocks or a plant trolley (drainage!). December–February: water only when the soil is completely dry and there is no frost. The main problem in winter is not the cold, but moisture during frost. March: remove the fleece as soon as the frosts are over. Make the spring cut straight away and give the first feed.
Potted lavender – your questions, my answers
How often should I water potted lavender?
Only once the top layer of soil is completely dry – roughly every 5–10 days in summer. Barely at all in winter. Waterlogging is the main enemy.
When should I prune potted lavender?
Twice: after the main bloom in July (to encourage a second flush) and in spring in March (to shape it). Never cut into the old wood.
Can lavender overwinter in a pot?
Yes – Lavandula angustifolia is hardy. Protect the pot: a sheltered wall, wrap it, raise it on feet, water hardly at all.
Which soil for potted lavender?
Herb soil mixed with a third of coarse sand or perlite. No standard potting compost – it holds too much moisture.
Why is my potted lavender not flowering?
The usual causes: too little sun, too much fertiliser (nitrogen), no pruning, or waterlogging. Check the spot, catch up on the spring cut.
What is the best soil for potted lavender?
Two parts herb or Mediterranean soil mixed with one part coarse sand or perlite. No standard potting compost – it holds too much moisture and encourages root rot. Garden centres also sell it ready-made as Mediterranean or herb soil.
Is potted lavender frost-hardy?
Lavandula angustifolia is hardy down to about -15 °C. In a pot, protect it anyway: place it against a sheltered wall, wrap the pot, water hardly at all. It is not the frost that kills lavender – usually it is the combination of moisture and frost.

“Potted lavender is my cheapest little luxury – it smells like the south of France, costs three euros and blooms as long as you simply leave it be.”
Treat yourself to a pot of lavender this summer – ideally right now, while the plants are fresh and in full bloom. Set it beside your seating corner, watch the bees arrive each evening, and just breathe it in. No garden project gives back so much for so little effort. And with the right cut in July, it returns even more beautiful next year.
