About Russian Tarragon
Artemisia dracunculoides · also called Russian tarragon, false tarragon · herb
Russian tarragon is a vigorous, hardy perennial in the wormwood family, taller and coarser than French tarragon but far easier to grow from seed. Its narrow green leaves carry a mild, slightly bitter anise note that strengthens as plants mature. Sun-loving and drought-tolerant, it spreads readily in poor, free-draining soil where pampered French tarragon would fail.
Preferred mix: Light, free-draining loam or sandy soil, neutral pH
Watch for — Weak, bland flavour: Often disappoints cooks expecting French tarragon's punch. Flavour is naturally milder; grow in lean soil and full sun, and harvest mature plants for the strongest taste.
Why russian tarragon needs this mix
Russian Tarragon is a hungry, thirsty leafy herb — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.
- Russian Tarragon 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 russian tarragon struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A poor, thin or sandy mix starves russian tarragon — 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. Russian Tarragon needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.
pH — does it matter for russian tarragon?
Russian Tarragon 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 russian tarragon 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.
Russian Tarragon 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 russian tarragon covers the timing and technique step by step.
