Black Diamond Watermelon

February 1, 2023

Black diamond watermelon is a type of heirloom, open-pollinated watermelon that is popular for home gardens and large commercial farms. It is known for its enormous size and juicy, sweet flesh. These melons can weigh in excess of 50 pounds, and they require a long growing season before gardeners can harvest fully ripe fruit.

Planting Guide

Black Diamond Melons grow best in full sun. They will thrive in rich, loose soil that is well-drained. The soil must be warm enough for the seed to germinate, but not so hot that the fruit will burn. To get the best results, you should plant the seeds in hills of 6 to 8 feet apart.

The seed should be planted 1/4 inch deep and covered lightly with seed starting mix. Once the seeds sprout, thin them to the strongest two or three plants.

Melons are easy to grow, but they are prone to pests and diseases. These include melon aphids, cucumber beetles, squash vine borers, and fungal diseases such as powdery mildew, alternaria leaf spot, downy mildew, and stem blight. To help prevent these pests from invading your black diamond watermelon patch, you should watch out for their signs and treat them accordingly.

When to Pick Your Black Diamond Melons

To pick your black diamond watermelons, you should look for several signs that they are ripe. These include the color of the skin, the appearance of the rind, and the condition of the vine tendrils. You should also feel the melon’s skin for any soft spots. When the melon has a light yellow belly and dull, dark green skin on the rest of its surface, it’s ripe.

How to Tell If Your Watermelon is Ripe

When you see the skin of a black diamond watermelon turn light green, it’s ripe. This is because the melon will have hardened into a hard rind and its pink-red flesh will be ready for picking. You can also check the melon’s rind by scratching it with your fingernail.

If the melon’s skin is thick, it’s not ripe. This is because the rind is too hard for you to pierce it with your fingernail.

Another way to check if a black diamond watermelon is ripe is by feeling it for signs of softness. It is easy to tell if the melon’s skin has softened by rolling it or lifting it. You should also check the place on the melon where it rested on the ground.

Choosing the Right Watermelon Varieties

Black diamond watermelons aren’t very common in North America, but they are widely grown throughout the South. They are considered an excellent late-season melon for home gardens and have dark blue-green, thick rinds that protect the sweet, firm, bright-red flesh.

These melons are great for blending into smoothies, making granita, and adding refreshing flavor to salads. They’re also a great addition to picnics or parties, where they can be enjoyed by many people at once. In addition, the melon’s high water content makes it a great source of fiber and antioxidants.
