The Black Diamond Watermelon is an Heirloom watermelon and an open-pollinated favorite. These get huge--40 to 50 pounds! Great for back yards and the farmers market crowds! The Black Diamond needs long, hot growing seasons for about 85 days. Make sure your growing area is well composted for best results. These will get dark green and slightly yellow on the under side. So, if you are looking for a bigger water melon, this is the one for you! Happy growing!!!
Plant early plant often
Imagine if you could be satisfied and content with your purchase. That can very much be your reality with the Black Diamond Watermelon.
