How to Grow Crimson Sweet Watermelon from Seed
Watermelon is a full sun favorite best if sown directly after the final spring frost but, for earliest starts, begin indoors 3-4 weeks prior. Plant 2-3 seeds 1" deep per individual cell or 6-8 ft apart directly in the garden in loamy, regularly moist, well-drained soil with a pH of 6.0-6.8.
Watermelon performs best when grown on 8-10" tall mounds of soil to ideally accommodate long, heavy trailing vines. Plants are heavy feeders, benefiting from a nitrogen-rich fertilizer every 2-3 weeks until fruiting, then reduce nitrogen in the fertilizer. Watermelon fruits are about 90 percent water and plants require heavy routine summertime watering to produce 20-30 lb melons. Smaller dwarfed types may be trellised for tighter grow spaces.
Crimson Sweet Watermelon seeds grow into vine-spreading tender annuals that crave the heat. Crimson Watermelon is a refreshing treat that’s easy for any gardener to grow.
Crimson Sweet Watermelon in the Vegetable Garden
Watermelon is the unofficial herald of summer and, without doubt, the largest and juiciest fruit you could possibly hope for in the garden. Most popularly known as a red-flesh fruit, watermelon is also available in both yellow and orange along with a surprising selection of shape and size. Most varieties boast 20-30 lb fruits with regular watering and, like pumpkins and gourds, may be pruned and pinched back to direct growth towards competition size melons.
Harvesting Crimson Sweet Watermelon
Most watermelons are ready to harvest about 90 days from sowing or when showing signs of ripeness. The most important tip to picking vine-ripened watermelon is to locate the small tendril attached to the melon on the vine. If this tendril is completely brown and dead, the melon is ripe for harvest but, if the tendril is still even slightly green, the watermelon is not ready.
Heirloom watermelon rinds will soften slightly when ripe and feel less like an impenetrable gourd. Use scissors or shears to carefully remove watermelon from the vine.
When it comes to harvesting watermelons of all types, there are some tips and tricks for scoping out ripeness. Visual cues such as checking the color on the bottom will show an off-white color if they’re still unripe. Crimson Sweet watermelons will be ripe once you see more of a yellow hue. Textural signs are the classic “thump” method as well as the gentle press. For “thumping” give a light knock on the rind to hear a hollow sound which indicates full maturity.
Harvest the ripe fruit in 80 days from the sowing date. Cut the stem near the fruit with a knife or gardening shears. Uncut Crimson Sweet Watermelon can be stored in room temperature for up to 3 weeks.
