How to Sow
Since tarragon seeds should be covered very lightly with soil, guard against drying out during germination. Once the seedlings are up, reduce watering to protect against root rot.
How to Harvest
Cut fresh sprigs from your garden and use right away. If you want to keep them for a while, place the base of stems in water like cut flowers. To collect seeds, watch the development of the flowers and pick the heads when the seeds are well-developed, leaving them to dry out of direct sun before separating the seeds.
