About Gattefosse's Mint
Mentha gattefossei · also called Gattefosse's Mint, Moroccan Mint · herb
Gattefosse's Mint is a rare Moroccan native prized for its intensely aromatic leaves with a cool, fresh menthol scent. It thrives in full sun with consistently moist, fertile soil. Drought-sensitive but vigorous once established, it spreads by runners and suits containers or herb borders where moisture can be maintained.
Preferred mix: Rich, moist, well-drained loam
Watch for — Mint rust (Puccinia menthae): Orange pustules on undersides of leaves. Remove and destroy infected material; do not compost. Rotate container soil annually and avoid overhead watering.
Why gattefosse's mint needs this mix
Gattefosse's Mint is a hungry, thirsty leafy herb — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.
- Gattefosse's Mint 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 gattefosse's mint struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A poor, thin or sandy mix starves gattefosse's mint — 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. Gattefosse's Mint needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.
pH — does it matter for gattefosse's mint?
Gattefosse's Mint 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 gattefosse's mint 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.
Gattefosse's Mint 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 gattefosse's mint covers the timing and technique step by step.
