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.

Mature size: 60–90 cm tall (24–36 in), 45–60 cm wide (18–24 in)

Watch for — Root rot: Caused by waterlogged or heavy soil. Ensure excellent drainage; raised beds or gritty soil mixes help prevent this common killer.

How to tell russian tarragon needs repotting

Repotting on a calendar is less reliable than reading the plant. For russian tarragon, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot russian tarragon

Every 2–3 years, into bone-dry mix. Russian Tarragon's growth habit — upright, bushy perennial herb; spreads moderately by rhizomes — sets the pace. 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.

What size pot to step russian tarragon up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Russian Tarragon stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot russian tarragon

Spring or summer, while russian tarragon is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting russian tarragon

Repot dry. Do not water russian tarragon for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty well-drained, lean sandy or loamy soil ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set russian tarragon at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep russian tarragon completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for russian tarragon

Russian Tarragon wants well-drained, lean sandy or loamy soil. Prefers lean, gritty, slightly alkaline soil (pH 6.5–7.5). Rich, fertile soils promote lush but flavorless growth. Excellent drainage is critical — standing water is fatal. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting russian tarragon — frequently asked questions

How often should you repot russian tarragon?

Every 2–3 years, into bone-dry mix for russian tarragon. Repot russian tarragon every 2–3 years into a snug pot of well-drained, lean sandy or loamy soil, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does russian tarragon need?

When is the best time of year to repot russian tarragon?

Should you water russian tarragon after repotting?

No — not straight away. Repot russian tarragon into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise russian tarragon after repotting?

Not immediately. Wait about 3 weeks after repotting russian tarragon. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
