Harvest Tips
Heather is not harvested for consumption. Cut flowering stems for fresh or dried arrangements in late summer to fall when blooms are fully open. For drying, cut stems and hang upside down in a cool, dry location for 2-3 weeks. Prune lightly after flowering (late fall or early spring) to maintain compact shape and encourage new growth.
