AnnualThis variety prefers a light and sandy growing area with plenty of space for large melons to form. Fruits have been known to grow up to 50 lbs a piece! Water this variety generously and consistently for about 10 days until the fruits are about the size of a tennis ball to get them started for success.
Can’t wait to grow next season
Always have loved black diamond watermelon will plant next year since didnt get early enough to plant this year. Cant wait.
Although I had a great germination rate, and great growth of vines and leaves, there was no actual fruit produced from my 6 plants. My cucumbers and acorn squash that were growing on the same trellis fruited as normal so I know it wasn’t lack of pollinators. I’ve eaten black diamond water melon that were produced in my zone for years and they are delicious! I’ll try again next year for sure.
👍💫

I am very happy with my heirloom seeds. I cannot wait to germinate them.
Started my seeds on 12/31/25. I’ve had almost 100% germination and the onion seedlings are a couple of inches tall at this point (1/9/26). Looking forward to a great harvest!
