Oh the glory days of summer! Vine-ripened, homegrown watermelon is one of the greatest pleasures of earthly existence. While most are familiar with crimson red flesh and bright green rinds, watermelon actually come in a wide range of colors and sizes. A simple slice will suit most, but for those looking for new preparations, try it with salt and chili powder, a common street food in Latin America, preserved as jam for the winter, or a jar of pickled rinds to go with a bit of ham. And, while everyone has their own method to check for ripeness, an old method is to harvest when the tendril opposite the fruit stem had dried up. Nutrients: vitamins A and C (very high) B6, thiamin, pantothenic acid, potassium, magnesium, copper, phosphorous.

Watermelons are very frost-sensitive and grow in warm, fertile soil in the full sun. Fruits grow on vines that grow from 8'-12' depending on the variety, so make space in the garden. Heat-loving but not drought-tolerant, keep evenly moist. In most climates they are easily grown by direct seed. In cooler northern climates, it is best to plant seeds indoors 1/2" deep in 3-4" pots 3 weeks before last frost. Transplant or direct seed after all danger of frost and when soil has warmed up Plant seeds: 1/2" deep, with 6 seeds about 5" apart in mounded hills spaced at 3' intervals, after danger of frost has passed. Thin each mound leaving the 3-4 strongest seedlings. Or plant in rows with seeds space 5" apart and thin to 18-24". Soil Temp: 75-95 F. Days to Sprout: 3-10. Seeds/Oz: 400-600. Seed Wt./100' Row: 2 oz. Yield/100' row: 50-100 lbs. Days to Harvest: 70-100. Seed Viability: 4-5 years.
