Start wormwood seeds

Start seeds indoors 10–12 weeks before transplanting outdoors. Press seeds lightly onto moist seed-starting mix without covering them, as light helps them germinate. Keep the surface gently moist in a bright location. Harden seedlings off over 10–14 days before transplanting, spacing plants 18–24 inches apart.

Choose the right spot

Plant in full sun or partial shade in lean, sandy or loamy soil that drains well. Wormwood tolerates dry conditions once established, but does not like waterlogged ground. Because the plant may inhibit the growth of some nearby plants, place it at a border or give it its own space rather than mixing it closely with vegetables and herbs.

Care and harvest

Cut plants back in early spring to encourage fresh growth. If harvesting for dried arrangements, cut stems in midsummer when the plant is flowering and hang small bundles in a dark, well-ventilated place. Store dried stems or leaves in a cool, dry location.

A note on traditional use
