About Lavandin
Lavandula x intermedia · also called Lavandin, Dutch lavender · herb
A naturally occurring and cultivated hybrid between Lavandula angustifolia and L. latifolia, lavandin is larger, more vigorous, and more heat-tolerant than English lavender. Its tall, branched flower stems and strongly camphorous-floral fragrance make it the dominant lavender of the French and Spanish essential-oil industry. Superb for large garden borders, hedging, and dried flower production.
Preferred mix: Very well-drained, lean, neutral to alkaline loam or sandy soil
Watch for — Root rot in wet soils: Despite overall vigour, lavandin is just as susceptible to Phytophthora root rot as other lavenders. Ensure perfect drainage; grow on a slight slope or raised mound in gardens with heavy clay or high rainfall.
Why lavandin needs this mix
Lavandin is a hungry, thirsty leafy herb — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.
- Lavandin grows fast and puts on a lot of soft leaf, so it draws heavily on both nutrients and water — a lean mix simply cannot keep up.
- Plenty of organic matter holds moisture evenly, which prevents the stress problems (bolting, bitterness, blossom-end rot) that come from a drying-then-flooding cycle.
- It still needs structure: rich does not mean airless, so grit, perlite or leaf mould keeps roots oxygenated.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons lavandin struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A poor, thin or sandy mix starves lavandin — growth stalls, leaves pale, and the plant bolts to seed early.
- A heavy, compacted, badly drained soil rots the roots and brings fungal problems despite all the feeding.
- Letting a rich mix dry to dust then drowning it causes the classic moisture-stress disorders this crop is prone to.
Under-feeding and inconsistent moisture. Lavandin needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.
pH — does it matter for lavandin?
Lavandin does best around pH 6.0-7.0 (slightly acidic to neutral). It is worth a cheap soil test for an outdoor bed; very acidic soil benefits from a little lime well before planting.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
For containers a good multipurpose or vegetable compost works for lavandin with extra feed through the season. For beds, the real win is digging in plenty of well-rotted compost or manure — that beats any bag.
Drainage and the pot
Rich but free-draining is the target: raised beds and large containers both deliver it. Mulch heavily to even out moisture and roughly halve how often you water.
Lavandin is usually grown for a single season, so "repotting" means starting fresh each year — never reuse exhausted, disease-prone compost for the same crop family. When the time comes, our repotting guide for lavandin covers the timing and technique step by step.
Lavandin soil — frequently asked questions
What is the best soil mix for lavandin?
3 parts rich peat-free compost : 1 part well-rotted garden compost or manure : 1 part perlite or grit (containers) / leaf mould (beds). Lavandin grows fast and puts on a lot of soft leaf, so it draws heavily on both nutrients and water — a lean mix simply cannot keep up.
Can I use normal potting soil for lavandin?
A poor, thin or sandy mix starves lavandin — growth stalls, leaves pale, and the plant bolts to seed early. For containers a good multipurpose or vegetable compost works for lavandin with extra feed through the season. For beds, the real win is digging in plenty of well-rotted compost or manure — that beats any bag.
Does lavandin need a special pH?
Lavandin does best around pH 6.0-7.0 (slightly acidic to neutral). It is worth a cheap soil test for an outdoor bed; very acidic soil benefits from a little lime well before planting.
Should I buy a bagged mix or make my own for lavandin?
