Using a food thermometer. Checking the temperature of your cooked meat, poultry, and seafood with a food thermometer is the only reliable way to make sure your food has reached a safe internal cooking temperature.
Planting Watermelons. The ideal date to plant watermelons varies according to the climate of the region. To produce the sugar necessary for sweet fruit, the melons need hot weather. Seedlings should not be transplanted until three to four weeks after the last average frost date in the spring. Starting seed indoors about six weeks before planting gives you a head start when the soil is warm enough.
Watermelons need at least 80-100 consecutive days of very warm summer temperatures, at least 80 degrees Fahrenheit. Watermelons also prefer warm nights, above 70 degrees Fahrenheit is preferred. Watermelons are a warm-season crop, very tender to frost and light freezes. Plan an average of 2-6 plants per person.
