About Winter savory
Satureja montana · also called mountain savory, sariette de montagne · herb
Winter savory is a hardy perennial cousin of summer savory with stronger peppery flavour and a low woody shrub habit. Long-lived in poor sunny soil; useful in pizza and bean dishes. Pet-safe in culinary amounts.
Satureja montana, a semi-evergreen dwarf sub-shrub in the Lamiaceae, is native to rocky slopes of southern Europe and the Mediterranean. Unlike annual summer savory (S. hortensis), it is a true woody perennial, hardy through most of the UK.
Prefers a lean, moderately fertile, sharply drained soil and tolerates (even favors) alkaline, poorer ground; heavy or rich soil weakens the plant and dilutes flavor.
Preferred mix: Free-draining loam
Watch for — Yellowing: Wet soil; improve drainage.

Why winter savory needs this mix
Winter savory is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Winter savory evolved on stony, sun-baked slopes — its roots expect to dry out hard and quickly between rains, so the mix must drain almost as fast as you pour.
- A lean, low-nutrient mix keeps growth firm and aromatic; a rich one gives soft, sappy, flavourless growth that flops and rots.
- It tolerates and often prefers a slightly alkaline soil, the opposite of most houseplants.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons winter savory struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Rich, moisture-holding compost is the classic killer of winter savory — especially over a cold, wet winter, when the base of the plant simply rots.
- A peaty, acidic potting mix is doubly wrong: too wet and the wrong pH direction.
- No grit means the rootball stays damp for days, which a dry-climate root system never copes with.
Growing winter savory in ordinary rich, moisture-retentive compost. Lean it out with at least a third grit, and never let it sit wet over winter.
pH — does it matter for winter savory?
Winter savory likes neutral to slightly alkaline soil, roughly pH 6.5-7.5. If your soil or compost is acidic, a little garden lime or extra grit nudges it the right way — the one common plant where you may add lime.
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
Bagged "herb" or "Mediterranean" mixes are usually fine for winter savory, but most standard composts need cutting hard with grit. The DIY ratio above is cheap and exactly right.
Drainage and the pot
Sharp drainage is everything: a terracotta pot with a big hole, gritty mix and never a saucer left full. Raised beds suit these herbs outdoors for the same reason.
A gritty mix barely breaks down, so winter savory needs little repotting — refresh the top layer and the grit every couple of years rather than potting on aggressively. When the time comes, our repotting guide for winter savory covers the timing and technique step by step.

What is the best soil mix for winter savory?
2 parts standard peat-free compost or loam : 1 part coarse horticultural grit : 1 part perlite or coarse sand. Winter savory evolved on stony, sun-baked slopes — its roots expect to dry out hard and quickly between rains, so the mix must drain almost as fast as you pour.
Can I use normal potting soil for winter savory?

Does winter savory need a special pH?
Winter savory likes neutral to slightly alkaline soil, roughly pH 6.5-7.5. If your soil or compost is acidic, a little garden lime or extra grit nudges it the right way — the one common plant where you may add lime.
Should I buy a bagged mix or make my own for winter savory?
