Watering at a glance

Base rhythm	Every 7–10 days
Spring / summer	Spring and summer: water deeply but only when the top few centimetres are properly dry — roughly weekly in the ground, more often only for pots in heat.
Autumn	Autumn: cut right back as growth slows; established plants need very little.
Winter	Winter: keep nearly dry, especially in pots — wet winter soil is the classic killer of rosemary, lavender and thyme.
Light	Direct sun (at least 4-6 hours)

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.

Ideal humidity: 30–50%

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

The watering schedule, season by season

Russian Tarragon is a lean, sun-loving Mediterranean herb — it grows best kept on the dry side and rots fast if it is watered like a leafy plant. The base rhythm for russian tarragon is every 7–10 days, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Spring & summer (active growth): Spring and summer: water deeply but only when the top few centimetres are properly dry — roughly weekly in the ground, more often only for pots in heat.
Autumn (slowing down): Autumn: cut right back as growth slows; established plants need very little.
Winter (rest / dormancy): Winter: keep nearly dry, especially in pots — wet winter soil is the classic killer of rosemary, lavender and thyme.

Drought-tolerant once established. Water deeply but allow soil to dry out between waterings; overwatering quickly leads to root rot. Reduce watering in winter.

How to tell russian tarragon needs water

A calendar is the worst way to water russian tarragon. Check the plant and the soil instead — for this species, look for these signals in order:

The top 3-4 cm of soil is fully dry and the pot is light.
Foliage looks slightly dull or limp in heat (recovers fast once watered).
For potted plants, the rootball has shrunk slightly from the sides.

The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering russian tarragon for a day is almost always safer than over-watering it.

Overwatering vs underwatering russian tarragon

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For russian tarragon specifically:

Signs you are overwatering

Yellowing, blackening or dropping lower foliage; a sour, wet pot.
Soft, rotting stems at the base — often fatal in rosemary and lavender.
Sudden collapse despite "looking thirsty" (it was actually drowning).

Signs you are underwatering

Crisp, brittle, browning foliage and stalled growth (less common — these herbs are drought-hardy).
For young, unestablished plants only, wilting in extreme heat.

Overwatering and rich wet soil are what kill russian tarragon, not drought. It evolved on dry, stony hillsides — err on the side of too little.

Water quality notes

Tap water is fine for russian tarragon; drainage and restraint matter, not water type.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For russian tarragon, the levers that matter most are:

Sharp drainage is everything — grit in the mix and a terracotta pot keep it alive.
Established plants in the ground are highly drought-tolerant and rarely need watering at all.
Pots dry faster and need more attention than open ground, but still let them dry between waterings.

Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of russian tarragon.
