Russian Tarragon (false tarragon) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Full sun, 6 or more hours daily, develops the best flavour and sturdiest stems. In shade growth is lank, weak and noticeably less aromatic. If your only bright window faces south, that's perfect for russian tarragon — same window any aroid would fry on.

Watering

Watering russian tarragon: when the top 3-4 cm of soil is dry; about every 7-10 days while establishing, then sparingly. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Drought-tolerant once established. Water moderately and let the soil dry between waterings. It dislikes constant moisture, which causes root rot and weak, watery flavour.

Soil and pot

Russian Tarragon grows best in light, free-draining loam or sandy soil, neutral ph. Far less fussy than French tarragon. Tolerates poor, dry ground; the key requirement is sharp drainage. Heavy, wet soils rot the roots, especially over winter. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Russian Tarragon sits happiest at around 30-50% humidity and 15-27°C (59-81°F). Prefers dry air and open, breezy sites. Outdoor humidity suits it well; good airflow keeps the dense foliage free of mildew and fungal problems. If you keep the room above 15 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed russian tarragon sparingly. Undemanding. A single light spring feed of balanced fertiliser or a thin compost mulch is enough. Excess nitrogen yields lush growth with diluted, weaker anise flavour. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on russian tarragon in the Growli community. Each is annotated with the most common cause so you know where to start.

• 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.
• Invasive spreading — Rhizomes can colonise a bed and self-seed. Grow in a container or contained area and remove flower heads before seed sets to limit spread.
• Root rot in wet soil — Yellowing and collapse in heavy or waterlogged ground. Provide sharp drainage, water sparingly, and avoid winter wet.
• Sprawling, floppy stems — Tall growth flops, especially if over-fed or shaded. Site in full sun, keep feeding lean, and cut back hard in late autumn to renew compact growth.

Propagation

Grows readily from seed sown in spring, unlike French tarragon, and is also easily increased by spring division of the rhizomatous clump or by basal cuttings. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Russian Tarragon is toxic to pets. Artemisia. The ASPCA lists tarragon (Artemisia dracunculus, of which Russian tarragon is the same species complex) as toxic to cats, dogs and horses; the toxic principle is the plant's essential oils, causing mild vomiting and diarrhoea. Keep pets from grazing it and contact a vet if significant amounts are eaten. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
