About Black Diamond

This full-season heirloom produces large, round to nearly round fruits, often weighing up to 50 lbs, characterized by a distinct dark green rind with a bluish cast. Its bright red, firm flesh is exceptionally sweet, making it excellent for fresh consumption. Market growers highly value this variety for its superior shipping qualities, especially popular in southern regions. For best success, plant seeds with the pointed end down and ensure consistent watering during early fruit development until they reach tennis ball size.
