About Provence Lavender

Lavandula × intermedia 'Provence' · herb

'Provence' is a tall, fragrant lavandin famous for long, slender pale-lilac flower spikes that dry beautifully and resist shattering. A sterile English-x-Portuguese hybrid, it is more heat- and humidity-tolerant than English lavender, making it a favourite in warmer gardens. It needs full sun, sharp drainage, and lean soil to thrive.

Mature size: 75-90 cm tall and 90-120 cm wide in flower

Watch for — Root rot in heavy soil: Wet clay or poor drainage rots the roots. Plant in raised, gritty beds and water only when the soil is dry.

How to tell provence lavender needs repotting

Repotting on a calendar is less reliable than reading the plant. For provence lavender, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot provence lavender

Every 2–3 years, into bone-dry mix. Provence Lavender's growth habit — tall, vigorous evergreen subshrub forming a wide silvery mound topped by exceptionally long, wand-like flower stems. — sets the pace.

What size pot to step provence lavender up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Provence Lavender stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot provence lavender

Spring or summer, while provence lavender is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting provence lavender

Repot dry. Do not water provence lavender for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty light, gritty, neutral-to-alkaline well-drained soil ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set provence lavender at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep provence lavender completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for provence lavender

Provence Lavender wants light, gritty, neutral-to-alkaline well-drained soil. Lean and fast-draining; amend with grit or coarse sand and avoid rich, wet composts. Copes with chalk and poor soils that defeat other herbs. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
