About Corsican Mint
Mentha requienii · also called Creeping Mint · herb
Corsican Mint is a tiny, ground-hugging mint with minute bright-green leaves and an intense peppermint scent released when stepped on, prized as a fragrant lawn substitute and between pavers. Unlike its tall cousins it forms a flat creeping carpet, needs moist soil and shelter, and is less cold-hardy, often grown as a short-lived perennial or annual.
Preferred mix: Moist, humus-rich, well-drained soil
Watch for — Drying out and dieback: Its shallow roots die fast if the soil dries. Keep consistently moist and avoid hot, exposed sites; brown patches signal drought stress.
Why corsican mint needs this mix
Corsican Mint is a hungry, thirsty leafy herb — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.
- Corsican 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 corsican 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 corsican 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. Corsican Mint needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.
pH — does it matter for corsican mint?
Corsican 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 corsican 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.
Corsican 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 corsican mint covers the timing and technique step by step.
