To grow lavender in a pot

Varieties best suited to growing in pots

For container growing, we recommend choosing varieties with a dense, compact habit. They will be perfect on your terrace or balcony!

Lavandula intermedia Walburtons Silver Edge - Lavandin

This lavender is notable for its distinctive foliage edged with white, which makes it very striking. It is slightly larger than other varieties, reaching up to 60 cm in height.

See the product sheet

Lavandula stoechas The Princess - French Lavender

This is a very attractive variety of Lavandula stoechas, notable for its intense bright-pink flowering and its dense, compact habit. However, it is less hardy than English lavender, so it is best to bring it under cover for winter.

When and how to plant lavender in a pot?

When to plant lavender?

Plant lavender in spring, around April, or in autumn (September–October), when temperatures are mild enough. In any case, avoid frosty periods. For stoechas lavender, which is quite tender, we recommend planting in spring.

Which pot and substrate to use?

Choose a fairly large pot, at least 30–40 cm in diameter. It must have drainage holes to allow water to drain (avoid self-watering pots!). We recommend a terracotta pot, as these are more breathable and aerated. In case of excess moisture, roots are less likely to suffocate than in a plastic pot. In addition, terracotta pots are more attractive and will help create a Mediterranean feel!

Lavender hates heavy, wet soils! It needs a very free-draining, even stony, and fairly poor substrate. To grow it, choose either potting compost for Mediterranean plants, or use garden soil mixed with coarse sand and small gravel to improve drainage. Likewise, lavender appreciates calcareous substrates, except for butterfly lavender, Lavandula stoechas, which prefers acidic substrates: for this one, you can add a little heather soil to the planting substrate to acidify it.

How to plant lavender in a pot?

1. Place a drainage layer at the bottom of the pot, for example expanded clay balls or gravel.
2. Then add the substrate, which must be well draining.
3. Remove lavender from its original pot, then place it in its new pot, centred.
4. Fill in by replacing some substrate around the rootball, and firm slightly to remove air pockets.
5. Water generously.

Where to position it?

Lavender is a Mediterranean plant that likes sun and heat! Place the pot in a sunny spot, sheltered from cold winds, for example against a south-facing wall. Lavender needs at least 6 hours of sun a day. Also, heat intensifies the scent of its flowers and ensures more generous flowering!

Choisissez la bonne variété - Préférez les lavandes compactes ( Lavandula angustifolia 'Hidcote', 'Munstead' ou lavandins pour pots plus grands) si espace limité. Les lavandes anglaises (Lavandula angustifolia) sont les plus adaptées en pot pour le climat britannique. Pot et drainage - Pot percé avec bon drainage, idéalement en terre cuite (perméable) ; diamètre adapté à la taille adulte (20–30 cm pour petits sujets, 30–40+ cm pour sujets plus volumineux). - Mettre une couche de billes d’argile au fond si nécessaire, puis un mélange très drainant : terreau de qualité + 30–40 % de grit/ponce/sable horticole ou perlite. Substrat et pH - Sol léger, pauvre à modérément fertile, bien drainé. Lavande préfère pH neutre à légèrement alcalin ; éviter les terres lourdes et acides. Exposition - Plein soleil : au moins 6 heures de soleil direct par jour pour une floraison abondante et un feuillage compact. Arrosage - Très modéré : laisser sécher la surface entre deux arrosages. Pour une plante établie, arroser seulement en cas de sécheresse prolongée (quelques heures d’arrosage profond toutes les 1–2 semaines en été selon météo). - Jeunes plants : maintenir un léger apport d’eau jusqu’à bonne reprise, sans saturer le pot. - Éviter l’eau stagnante qui provoque pourriture des racines. Fertilisation - Peu d’engrais : engrais faible en azote ou slow-release au printemps, ou un apport léger de compost bien mûr. Pas d’engrais riche en azote (favorise la végétation au détriment des fleurs). Taille et entretien - Tailler juste après la floraison (fin été) : réduire la floraison et tailler la silhouette en coupant environ 1/3 de la longueur, sans tailler dans le vieux bois (parties ligneuses sans bourgeons). Si nécessaire, un léger toilettage au printemps. - Enlever fleurs fanées pour encourager une seconde floraison et améliorer l’apparence. Hivernage (climat britannique) - Lavande tolérante au froid mais sensible à l’humidité hivernale : placer pot à emplacement ensoleillé et bien drainé, à l’abri des vents humides. - Sur sols très humides ou en hiver très pluvieux, surélever le pot (briques, pieds) ou rentrer sous abri non chauffé. Ajouter une protection autour du pot (paillage sec, voile) si gel fort. Rempotage et renouvellement - Rempoter tous les 2–4 ans si la plante devient à l’étroit ; renouveler partiellement le substrat et tailler légèrement les racines si nécessaire. - Division peu pratiquée ; multiplication facile par boutures semi-ligneuses après floraison. Problèmes courants - Feuilles jaunes/ramollies : excès d’eau/maigre drainage. - Croissance étiolée, peu de fleurs : manque de soleil ou excès d’azote. - Pourriture/chancre : limiter l’humidité, améliorer drainage. Astuce finale - Garder le pot dans un endroit très lumineux et plutôt sec : la clé du succès est le drainage, le soleil et une taille régulière après floraison. Avec ces soins, lavande en pot offre parfum et floraison pendant de nombreuses années.

Although lavender is fairly drought-tolerant, when in a pot substrate dries out quickly, and regular waterings will help it thrive and grow at its best. Wait each time until substrate is dry before watering again. When watering, avoid leaving water standing in saucer. You can also slightly raise pot using stones or small shims to allow water to drain properly. Limit waterings in winter, from November to February–March, but continue nevertheless to water from time to time so substrate does not dry out completely. If cultivating butterfly lavender (Lavandula stoechas), preferably water with rainwater, as tap water may be too calcareous for it. Likewise, we advise bringing it under frost-free shelter for winter, as it is not very hardy.

As lavender naturally grows in soils poor in minerals, it does not need fertiliser. Simply top-dress each year, replacing substrate in top few centimetres.

Lavender also needs regular pruning, otherwise it will tend to thin out at base. Pruning will encourage production of new vigorous shoots while promoting generous flowering. Pruning is carried out each year after flowering in late summer, or possibly in late winter–early spring. Use a well-sharpened shear, and prune on year’s shoots, still green. Pruning will help keep lavender dense and compact. Try to prune so as to preserve a rounded, ball-like shape. In any case, avoid severe pruning at all costs, and do not cut into old wood! Lavender does not produce new shoots from old wood.

We recommend repotting lavender every two to three years. Choose a pot only slightly larger than previous. In years when not repotting, perform a top-dressing.

Finally, if you want to propagate it, you can take cuttings. Discover our illustrated tutorial !
