Harvest Tips
Berries ripen in early summer (June-July) when they turn blue-black and are soft to touch. Harvest by hand-picking individual berries or stripping clusters. Berries are rarely harvested commercially for human use; leave most for wildlife. Berries have a slightly sweet-tart flavor and can be eaten fresh or used in jams. Best twig color occurs in winter; prune or harvest branches for arrangements after leaves have fallen and frost has set.
