How to grow summersweet

Clethra alnifolia

When to plant summersweet

Plant this deciduous shrub while dormant, in fall or early spring. Extension guidance rates fall (early enough for roots to establish before the ground freezes) as the best time and spring, just before growth begins, as the next best.

Summersweet is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
