Mugwort in Zone 6a & 6b

Artemisia vulgaris

When to plant mugwort in zone 6b

Zones 6a and 6b share the same average frost dates in our data, so this page covers both.

Method: Direct sow: Direct-sow outside. Mugwort doesn't transplant well, or doesn't need the extra time indoors.

Start indoors	Not typically started indoors
Direct sow / transplant outside	Apr 25–May 2
Estimated harvest	Apr 24 '28–May 1 '28 (First real harvest the season after planting)

Spacing: about 4 square feet per plant (square-foot-gardening spacing). Mature height: 2-4 ft.

Mugwort has a long history in cooking and herbal medicine, and it is one of the more difficult plants to have in a garden.

How mugwort fits zone 6's season

Zone 6b's frost-free window runs about 173 days, from April 25 to October 15. Mugwort takes about 1 growing season to reach first worthwhile harvest, so what matters here is how many of these seasons it gets, not whether one is long enough.

Mugwort is hardy in zones 3-8, so in zone 6b it stays in the ground through winter and comes back rather than being replanted. Allow about 4 ft of spread at maturity.
