About Russian Tarragon
Artemisia dracunculus var. sativa · also called Russian Tarragon, Wild Tarragon · herb
Russian Tarragon is a vigorous, drought-tolerant perennial herb grown for its anise-scented foliage. Far hardier than French tarragon, it thrives in full sun and well-drained soil. Flavor is milder than the French variety. Cut back in autumn and divide every 2–3 years to maintain vigor.
Preferred mix: Well-drained, lean sandy or loamy soil
Watch for — Root rot: Caused by waterlogged or heavy soil. Ensure excellent drainage; raised beds or gritty soil mixes help prevent this common killer.
Why russian tarragon needs this mix
Russian Tarragon is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Russian Tarragon 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 russian tarragon 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 russian tarragon — 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 russian tarragon 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 russian tarragon?
Russian Tarragon 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 russian tarragon, 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 russian tarragon 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 russian tarragon covers the timing and technique step by step.
