How To Grow
How To Grow
Sowing: In regions with cooler climates, it's advisable to start Black Diamond watermelon seeds indoors approximately one month before transplanting. Plant three seeds per peat pot, burying them 6 millimeters deep. Ensure the soil remains consistently warm, ideally between 27-29 degrees Celsius. Once true leaves emerge, retain only the strongest seedling and transplant it about a week after the last frost. Space two or three plants in each hill, allowing for 1.8-2.4 meters of space in all directions. Alternatively, gardeners in warmer climates can direct sow watermelon seeds once the soil temperature reaches at least 24 degrees Celsius. Plant six seeds per hill, thinning to the two or three strongest seedlings upon emergence. Black Diamond watermelon seeds thrive in full sun and nutrient-rich, well-draining soil. Using black plastic can help warm the soil for young seedlings.
Growing: Apply a generous layer of mulch as soon as the vines begin to develop to suppress weeds and protect the melons from direct soil contact. Keep the soil consistently moist until fruit development begins, watering only if the soil becomes completely dry thereafter. Be vigilant for insect pests, which may pose a threat to the plants.
Harvesting
Harvesting
While various methods exist for determining watermelon ripeness, knowing the approximate mature size of the melon aids in gauging ripeness. One approach involves tapping the watermelon with your knuckles and listening for a dull thump rather than a hollow sound. Additionally, check the underside of the melon where it rests on the ground; ripe melons typically exhibit rich yellow skin in that area. Another indicator of ripeness is the tendril closest to the stem, which begins to brown as the melon ripens. Once harvested, watermelons can usually be stored for several weeks in a cool environment.
Seed Saving
Seed Saving
Given that watermelons have the potential to cross with other varieties, isolation may be necessary to maintain genetic purity. Once the melon is ripe, the seeds will also be mature. Cut open the melon, extract the seeds, and wash them to remove any residual pulp. Allow the seeds to air dry for approximately one week before storing them in a cool location for up to four years.

Regularly inspect for any signs of damage, maintaining optimal storage conditions for the best results in growing these delicious watermelons.
Can I Grow Melon Seed Sprouts: Yes, you can grow melon seed sprouts. Soak melon seeds in water for a few hours. Plant them in a well-draining tray or container with moist soil. Keep them in a warm, sunny spot. Water regularly and watch for sprouting in about 4-7 days. Harvest when the sprouts are a few inches tall.
