Tarragon is the quiet aristocrat of the herb garden — the anise-scented backbone of béarnaise sauce, classic chicken dishes, and good Dijon-style vinegars. But there’s a catch that trips up nearly every beginner: the tarragon worth growing, true French tarragon (Artemisia dracunculus ‘Sativa’), produces sterile flowers and cannot be grown from seed. Any packet of “tarragon seed” you find is almost certainly Russian tarragon, a coarse, nearly flavorless cousin that grows like a weed and disappoints in the kitchen. French tarragon must be propagated from divisions, cuttings, or runners taken from an existing plant — so the first step to growing great tarragon is buying a started French tarragon plant from a reputable nursery and tasting a leaf to confirm that bright, peppery, licorice punch. Get that right, and you have a hardy perennial that returns every spring for years with very little fuss. This guide walks through planting, the light and lean-soil conditions tarragon actually wants, watering, the all-important task of dividing it every few years to keep the flavor strong, and how and when to harvest.

Key Takeaways
- Buy French, not seed: True French tarragon is sterile and propagated only from plants, cuttings, or division — seed-grown tarragon is the flavorless Russian type.
- Sun and lean soil: Give it full sun and light, well-drained, even slightly poor soil — rich, wet ground weakens the flavor and rots the roots.
- Water sparingly: Drought-tolerant once established; let the soil dry between waterings and never let it stay soggy.
- Divide every 2–3 years: Plants lose vigor and flavor with age — dividing in spring rejuvenates them and gives you free plants.
- Harvest often: Snip sprigs through summer for the best flavor; regular cutting keeps growth bushy and tender.
- Hardy perennial: French tarragon is hardy in USDA zones 4–8 and actually needs a winter chill to perform well; protect it in cold zones and grow it as an annual or potted plant in hot ones.
French vs. Russian tarragon
This distinction matters more than any growing tip, so it’s worth dwelling on. French tarragon is the culinary herb — narrow, glossy green leaves with a sweet, complex anise-and-pepper flavor. It rarely flowers, and when it does the blooms are sterile, so it produces no viable seed. Russian tarragon (Artemisia dracunculoides) is taller, coarser, lighter green, sets abundant seed, and tastes of almost nothing — sometimes faintly bitter or grassy. Because only Russian tarragon can be sold as seed, anything labeled “tarragon seeds” will grow into the wrong plant.
The safe route is to buy a small French tarragon plant in spring from a garden center or herb specialist. Crush and smell — or nibble — a leaf before you buy: real French tarragon delivers an unmistakable, almost numbing licorice kick. If it smells like cut grass, walk away. Once you have one good plant, you’ll never need to buy another, because dividing and taking cuttings keeps you in tarragon indefinitely.
Planting tarragon
Plant French tarragon in spring after the last frost, once the soil has warmed. Choose a spot in full sun — at least 6 to 8 hours of direct light — though in very hot southern climates it appreciates a little afternoon shade. The single most important condition is drainage. Tarragon is a Mediterranean-steppe plant adapted to lean, dry ground; it will not tolerate heavy, waterlogged soil and rots quickly in it.
Work the bed to loosen it and, if your soil is heavy clay, dig in coarse sand or fine gravel along with a little compost to open it up. Aim for a light, sandy or loamy soil with a near-neutral pH around 6.5–7.5. Resist the urge to enrich it heavily: too much fertility produces lush, floppy growth with diluted, watery flavor. Set plants about 18 to 24 inches apart, since a mature French tarragon forms a sprawling clump 2 to 3 feet wide and up to 2 feet tall. After planting, water it in and then let it settle — established tarragon is one of the more drought-tolerant herbs you can grow.
Growing tarragon in containers
Tarragon does well in pots, which is the easiest way to give it the sharp drainage it craves and to overwinter it in marginal climates. Use a container at least 12 inches deep and wide with ample drainage holes, fill it with a free-draining potting mix cut with extra perlite or grit, and place it in full sun. Container tarragon dries faster, so check it more often, but still err on the dry side. Refresh the top inch of mix each spring and divide or repot every couple of years to keep it productive.
Watering and feeding
Once established, tarragon is genuinely drought-tolerant and far more likely to die from overwatering than from neglect. Water newly planted divisions regularly for the first few weeks while roots establish, then back off. After that, water only when the top inch or two of soil has dried out — typically once a week in summer, less in cooler weather and almost never in winter. Soggy roots are the number-one killer of tarragon, so make sure water drains freely and never leave a pot standing in a saucer.
Feeding should be minimal. A single light application of balanced fertilizer or a top-dressing of compost in early spring is all tarragon needs for the whole season. Over-fertilizing, like over-watering, produces leafy growth at the expense of the essential oils that give tarragon its flavor — so lean is better. A light mulch of gravel rather than rich organic matter keeps the crown dry and discourages rot.
Dividing and propagating
French tarragon naturally declines after three or four years — the center of the clump grows woody and the flavor fades. The cure is division, which both rejuvenates the plant and multiplies your stock. Every two to three years in early spring, just as new growth appears, dig up the whole clump, shake off the soil, and pull or cut the root mass into several sections, each with healthy roots and a few growing shoots. Replant the vigorous outer divisions and discard the tired woody center. Watered in and given a few weeks, each division grows into a full plant.
You can also propagate from stem cuttings in early summer: take a 4- to 6-inch tip cutting, strip the lower leaves, dip in rooting hormone, and set it in moist, gritty mix kept lightly humid until it roots in a few weeks. Underground runners can be detached with roots attached and potted up the same way. Because you can’t grow it from seed, knowing how to divide and take cuttings is what keeps French tarragon in your garden for the long haul — and lets you share it.

Harvesting tarragon
Begin harvesting lightly once the plant is established and putting out plenty of new growth, usually by early summer in its first full year. Snip sprigs from the top of the stems with scissors; cutting the tips encourages bushy, branching growth and keeps a steady supply of tender new leaves, which carry the best flavor. You can harvest regularly all through the growing season. The flavor is at its peak in early to mid-summer, before any flowering and while the foliage is young.
For a bigger cutting, you can shear the whole plant back by up to a third in mid-summer; it flushes back with fresh growth. Stop heavy harvesting in early fall so the plant can build reserves before winter. Tarragon’s flavor is delicate and fades fast when dried, so it is best used fresh. To preserve a surplus, freeze sprigs whole in a bag, freeze chopped leaves in ice-cube trays with a little water or oil, or steep the leaves in white wine vinegar to make classic tarragon vinegar — by far the best way to capture its flavor for winter.

Overwintering and seasonal care
French tarragon is a hardy perennial in USDA zones 4 through 8 and, interestingly, it actually needs a period of winter cold and dormancy to perform well the following season — which is why it struggles in frost-free climates. The plant dies back to the ground in late fall and re-emerges in spring; don’t panic when it disappears. In zones 4–5, mulch the dormant crown with straw or evergreen boughs after the ground freezes to protect it from heaving and harsh cold, removing the mulch as growth resumes in spring.
In hot, frost-free climates (zones 9–11), tarragon often sulks because it never gets its winter rest; many gardeners there grow it as a cool-season annual or keep it potted and give it an artificial chill. Cut spent stems back in late fall, keep winter watering to almost nothing so the dormant roots don’t rot, and avoid feeding until spring growth begins.

Common problems
Weak or fading flavor
Often an aging plant (divide it), too much water or fertilizer (lean out the soil), or — most commonly — it’s actually Russian tarragon. Taste before you trust.
Root rot and wilting
Soggy soil is almost always the cause. Improve drainage, water less, and never let the crown sit wet. In pots, ensure free-flowing drainage holes.
Powdery mildew or rust
Crowded, damp foliage invites fungal problems. Space plants for airflow, water at the base, and thin congested growth.
Plant disappears in winter
That’s normal — French tarragon is deciduous and dies back to the roots, returning in spring. Don’t dig it up or overwater the dormant crown.
Frequently Asked Questions
Can you grow French tarragon from seed?
No. True French tarragon produces sterile flowers and sets no viable seed, so it can only be propagated from plants, cuttings, runners, or division. Any seed sold as “tarragon” is the inferior, nearly flavorless Russian tarragon. Always start with a purchased French tarragon plant and taste a leaf to confirm its strong anise flavor.
How much sun and water does tarragon need?
Give it full sun — 6 to 8 hours a day — and lean, well-drained soil. It’s drought-tolerant once established, so water only when the top inch or two of soil dries out, roughly weekly in summer. Overwatering and rich, soggy soil are the main causes of weak flavor and root rot.
How often should I divide tarragon?
Every two to three years in early spring. French tarragon loses vigor and flavor as the clump ages and the center turns woody. Digging it up, splitting it into rooted sections, and replanting the healthy outer pieces rejuvenates the plant and gives you free new plants.
When is the best time to harvest tarragon?
Harvest sprigs regularly through the growing season, with the peak flavor in early to mid-summer before flowering. Snip the tender tips to encourage bushy growth. Stop heavy cutting in early fall so the plant can store energy for winter dormancy.
Is tarragon a perennial that comes back every year?
Yes — French tarragon is a hardy perennial in USDA zones 4–8 that dies back to the ground in winter and re-emerges each spring. It actually needs a winter chill to thrive, so it struggles in frost-free climates, where it’s often grown as a potted or annual plant instead.
Start with a genuine French tarragon plant, give it sun and sharp drainage, water it sparingly, and divide it every few years, and you’ll have one of the most rewarding herbs in the kitchen returning faithfully each spring. Lean soil and a light hand are the whole secret — pamper it and the flavor fades, treat it tough and the anise punch stays bold.
