In order to get juicy, sweet watermelon, you need to select the right option and time your planting to suit your zone. These fruits need anywhere from 90 to 130 days from seed to harvest, making them a tough plant to grow in cooler climes.
Short Season Watermelon Growing
Big melons need about 4 months of warm, frost free weather. In cooler climates, the seeds will need to be started indoors and planted out after any danger of frost has passed, usually 6 weeks prior. Harden off seedlings and prepare the bed by mixing in a generous amount of compost. The smaller varieties are the best choice, but there are some large fruits suitable for shorter seasons. Here are a few short season watermelon varieties for northern gardeners:
Sugar Baby- A smaller variety, with dark, almost black rind, and reddish orange fleshYellow Doll- A fun choice with small fruit, thin rind and surprising yellow fleshCole’s Early- Developed as an early hybrid, large striped fruit, sweet, pinkish red flesh

Playing with Color

There are now seedless hybrids, types with different colored rinds, and even a rainbow of flesh tones. You can find orange, yellow and even pink fleshed types of watermelon to grow. Each has classic watermelon flavor but may vary in intensity and sweetness. Plant several of these choices and you can make a beautiful fruit salad filled with color.
