About Duke
Duke is a very popular early northern highbush blueberry with firm, light-blue berries and strong productivity. It blooms relatively late for an early-ripening variety, which can help it avoid some spring frost issues.
Growing Duke Blueberry
Prune enough to prevent overcropping, because heavy set can reduce berry size. Wait for full blue color and a little extra hang time before picking for best flavor.
