How to Grow Russian Tarragon from Seed in South Africa
Grow a generous clump of Russian tarragon for fresh leaves and a soft green backdrop in your herb garden. Start with a small sowing, give the young plants steady moisture, then let this upright perennial settle into a sunny, well-drained spot.
Russian tarragon grows from seed, but it is not French tarragon. Its leaves are generally less intensely flavoured and can taste grassy or slightly bitter. Choose it for its own character; do not expect seed-grown plants to reproduce French tarragon’s flavour.
Meet your Russian tarragon
Choose a pack of Tarragon (Russian) Seeds for your herb garden. GARDENING.co.za offers 1 g and 5 g raw-seed packs. Raw describes the seed form, not its chemical-treatment status.
This is the Russian seed-grown form of Artemisia dracunculus, an herbaceous perennial with branching stems and narrow leaves. You may encounter the name A. dracunculoides in other references. No additional named cultivar or French-tarragon identity is confirmed for these packs.
Quick Grow Facts
Upright, bushy perennial. The supplier lists 100–150 cm tall; allow roughly 50 cm of width as a general planning guide, with room to expand.
Full sun and freely draining soil. Shelter young plants from harsh wind; provide some afternoon relief during severe heat.
The displayed label and matching supplier listing say 5 mm (0.5 cm). Use a fine, loose covering, not a compacted crust.
15–20°C is a useful general sowing-medium range. The label gives 7–14 days; emergence can take longer and is not guaranteed.
Start with 45 cm between garden plants. Leave extra space where clumps spread or humid conditions restrict airflow.
Pick lightly once plants are well rooted and making plenty of new growth. The label’s 60–80 days is an estimate without a stated starting point or harvest stage.
The Gro-Pak listing for the matching 5 g raw-seed SKU supports the depth, spacing, height and timing above. The width is general Russian-tarragon guidance, not a measured promise for your packet.
Give tiny seeds a steady start
- Prepare a small batch. Use clean trays or small pots with drainage holes and fresh, fine seed-sowing medium. Moisten the mix before sowing. A gram contains many seeds, so there is no need to sow the whole pack at once.
- Sow thinly. Spread seeds sparingly and add the label’s 5 mm of fine medium. Water gently so seeds are not washed into deeper pockets.
- Keep the tray bright and moderately warm. Aim for 15–20°C in the medium as general guidance from Unwins’ Russian-tarragon instructions. That is not a temperature supplied for this seed lot. Avoid a sealed propagator in fierce sun.
- Keep the seed layer evenly moist. Check it daily. Use a fine rose or brief bottom-watering, then drain thoroughly. A wet surface does not prove that the root zone is well aerated.
- Ventilate after emergence. Give seedlings good light and space. Label the sowing date and keep the packet so a slow batch can be assessed properly.
Light, depth and chilling: the displayed packet specifies no separate light/dark treatment or cold preparation. General sources vary: some lightly cover Russian-tarragon seed, others surface-sow it; the RHS plant profile mentions cold stratification while its growing guide describes spring sowing without a chilling step. Do not add soaking, scarifying or chilling on guesswork. If your physical packet differs, or a carefully managed sowing remains slow, ask us to check the current supplier directions before treating the remaining seed.
Review the tray at 7–14 days, but do not discard it solely because that date has passed. Other seed suppliers describe several weeks. Different seed sources and conditions explain why a general guide cannot certify a lot’s germination performance.
Move strong seedlings into their growing space
Trays make the tiny seedlings easier to monitor. Move them into individual small pots when they have several true leaves and can be handled without crushing the stems. Lift with the roots supported; thin crowded seedlings rather than pulling a tangled clump apart roughly.
Harden indoor-raised plants gradually for about two to three weeks. Begin with sheltered outdoor periods, then increase exposure to sun and wind. Plant out when roots hold the potting mix together, new growth is steady and damaging frost is no longer expected.
Direct sowing is also possible in a sheltered, weed-free bed once the soil warms in spring. Mark the row, keep the surface from drying or crusting and thin to 45 cm. Use the same garden spacing for a leaf-harvest bed; dense cut-flower rows are not appropriate for this tall perennial herb.
For a container, choose a stable pot with drainage holes and space for the clump to develop; a pot at least 30 cm across is a practical starting point, not its permanent size limit. Repot when roots crowd the container. Set the crown at its previous depth and keep the drainage outlet clear.
Choose the season that fits your garden
The label says spring or autumn. Use these regional starting points alongside your local frost dates, rain and actual soil temperature; they are practical adaptations, not South African cultivar-trial results. SANBI’s horticultural zones explain why rainfall and frost risk differ across the country.
Winter-rainfall Western Cape
Spring offers a warming start. Early autumn may work in mild sites while the soil remains warm, but protect trays from downpours and avoid planting into ground that stays wet all winter. Plan summer irrigation before sowing.
Frost-prone interior
Start under protection as spring approaches and plant out after damaging frost risk. Autumn seedlings need enough establishment time and shelter; do not treat the mature plant’s hardiness as proof that a newly emerged seedling tolerates a cold snap.
Humid coast and KZN Midlands
On the warm coast, favour a mild spell over peak heat and persistent heavy rain. Use airy spacing and a well-drained bed. In frost-prone Midlands gardens, use the interior spring approach rather than assuming coastal conditions apply.
Hot-dry or subtropical interior
Choose a milder spring or autumn window and protect tiny seedlings from hot wind. In frost-free lowveld sites, cooler-season establishment may be easier; in frost pockets, wait for spring. Give afternoon shelter during extreme heat and check pots frequently.
Keep roots drained and fresh shoots coming
Water newly planted clumps through dry spells, checking the original root ball as well as the surrounding soil. As roots establish, water according to soil moisture rather than a fixed daily schedule. Avoid standing water; container plants still need attention even when established plants in the ground cope well.
Prepare the bed with modest amounts of well-rotted compost. Do not repeatedly feed a stressed or waterlogged plant. For actively growing pots, use a suitable balanced fertiliser sparingly at its labelled rate. University of Maryland’s container-herb guidance supports light feeding and periodic repotting.
Lightly pinch or pick shoot tips after establishment to encourage branching. Remove developing flower heads when leaves are your priority and to limit self-seeding. Give leaning stems discreet support in exposed gardens; avoid tying a whole clump into a tight, poorly ventilated bundle.
Cold weather can bring seasonal dieback. Mark the crown and reduce watering as growth slows, without letting a pot become completely dry. Remove dead growth without cutting into fresh basal shoots. A dormant clump is not automatically dead, but a soft, rotting crown needs drainage problems addressed. General pruning and growth form are described in the RHS Russian-tarragon profile.
Pick leaves to suit the plant, not a deadline
Begin with a few tender shoot tips from a strong, settled plant and leave plenty of foliage for regrowth. Delay picking if the plant is small, cold-stalled or recovering from transplanting. The packet’s 60–80-day figure does not establish whether the clock begins at sowing or transplanting, or whether it means a first light picking.
Use clean scissors, wash harvested leaves and try a small amount in a dish before adding more. Russian tarragon can be grassy and slightly bitter; growing it longer or feeding it more will not turn it into French tarragon. Use fresh leaves when possible. The RHS tarragon guide explains the flavour distinction and shoot-tip harvest.
If seeds or young plants struggle
No seedlings yet
Check sowing depth, crusting, seed-layer moisture and actual medium temperature. Drying after germination begins can kill the emerging root; cold or flooded mix can also delay or spoil the batch. Keep sowing notes and ask for lot-specific advice before adding a treatment.
Seedlings fall over
A pinched, rotting stem at soil level can indicate damping-off. Remove affected seedlings, improve ventilation and drainage, and start any replacement sowing in clean equipment with fresh medium. Do not assume an improvised kitchen spray will cure it.
Long, pale or weak growth
Check light and crowding before feeding. Move seedlings into brighter conditions gradually and give them room. A sudden jump from a dim indoor spot to strong outdoor sun can scorch tender leaves.
Wilting after planting
Feel the root ball: it may be dry even when the bed surface looks damp. Alternatively, wet roots, hot wind or transplant damage may be responsible. Correct the cause and pause harvesting while the plant recovers.
Spotted or powdery leaves
Inspect both leaf surfaces. Rust and powdery mildew can affect tarragon; improve airflow and avoid leaving foliage wet unnecessarily. Seek a diagnosis before spraying. Use only a locally registered product labelled for the crop and problem, observing all harvest intervals.
University of Minnesota’s seedling troubleshooting advice explains common light, moisture and damping-off problems. These symptoms are clues, not a laboratory diagnosis.
Keep sowing seed separate from food
These packets are for growing plants, not eating the seed or producing raw sprouts. Raw seed is not proof of untreated, organic or food-grade status. Follow the physical packet’s treatment and crop-use directions; keep seed and sowing supplies away from children and pets, and wash your hands after handling.
Use correctly identified, healthy leaves in small, occasional culinary quantities, subject to any treatment restrictions. Do not taste an unidentified plant, use ornamental lookalikes, or infer that essential oils and concentrated extracts are safe from the herb’s kitchen use. NC State’s species profile also notes possible skin irritation; use gloves if handling the plant irritates your skin. No medicinal or pregnancy-safety claim is made here.
Keep browsing animals away. The ASPCA lists tarragon as toxic to dogs, cats and horses. Contact a local vet promptly if an animal eats it.
