Growing Tips
Only French tarragon has culinary value; Russian tarragon (seed-grown) has inferior flavor — always propagate from verified French tarragon stock.
Divide plants every 3-4 years in spring; crowded clumps lose vigor and produce less aromatic foliage.
In cold climates, mulch crowns heavily in fall; tarragon goes dormant in winter and benefits from freeze protection below -15C.
