SOW
When to Sow Russian Tarragon in the UK
Sow thinly indoors from February to April, cover lightly and plant out after hardening off once frost risk has passed.
Use that window as a practical starting point rather than a fixed deadline. In colder or exposed areas, delay outdoor sowing and planting; in mild sheltered areas, the earlier end of the range may work. Tender crops should remain protected until frost risk has passed.
Sowing Indoors
Sow Russian Tarragon in small pots or modules. Give seedlings bright light and avoid burying very fine herb seed deeply; thyme is best surface-sown.
Sowing Outdoors
Direct sow Russian Tarragon when conditions are suitable, or plant out module-grown seedlings after hardening off.
PLANT
Spacing and Planting Out
Allow 20–30cm between mature plants.
Before planting outside, harden off indoor-raised plants over 7–10 days unless the crop is fully hardy and already accustomed to outdoor conditions. Water the planting hole or container first and avoid leaving young roots exposed to sun or wind.
SMALL SPACES
Growing Russian Tarragon in Pots and Containers
Use a 25–30cm deep pot with drainage holes. Choose a free-draining mix and full sun; established plants dislike sitting wet.
Container checklist
- Use drainage holes and raise pots slightly so surplus water can escape.
- Fill with fresh peat-free compost suited to edible crops.
- Leave a watering lip below the rim and check pots more often in sun or wind.
- Use a strong support at planting time if the mature crop will climb or become top-heavy.
CARE
Watering and Feeding
Water young plants regularly, then let the compost surface dry between thorough waterings. Avoid rich feeding; a light spring feed is enough for perennial herbs.
Variety note: Grow in full sun in free-draining compost, trim regularly to encourage fresh shoots and use a roomy 30cm pot if containing its perennial growth.
WATCH FOR
Common Problems
Slow or patchy germination
Some herb seed is naturally slow. Keep the surface evenly moist, use fresh seed compost and avoid repeated digging to check it.
Leggy seedlings
Move seedlings into stronger light as soon as they emerge and avoid excessive warmth after germination.
Bolting or woody growth
Heat and dry roots push leafy herbs to flower; older perennial herbs become woody if never trimmed. Harvest little and often.
PICK
Harvesting Russian Tarragon
Pick young leafy shoots from late spring to early autumn once plants are established.
Begin light picking once plants are established, usually 6–12 weeks after sowing, and never strip more than one third at once. Harvest in the coolest part of the day where practical and handle produce gently. Regular picking encourages continued cropping in fruiting and cut-and-come-again plants.
GROW TOGETHER
Companion Plants
Herbs can share a windowsill or patio grouping, but combine plants with similar watering needs. Keep dry-loving thyme away from constantly moist watercress or coriander compost.
QUESTIONS
Frequently Asked Questions
Can I grow Russian Tarragon in pots?
Use a 25–30cm deep pot with drainage holes. Choose a free-draining mix and full sun; established plants dislike sitting wet.
How long does Russian Tarragon take to harvest?
Begin light picking once plants are established, usually 6–12 weeks after sowing, and never strip more than one third at once.
Why is my Russian Tarragon growing weak and leggy?
It needs brighter light and usually less heat after germination. Turn pots regularly, avoid crowding and pinch suitable leafy herbs once established.
