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.
This part is simple. The watermelon you planted will be ready about 80 or so days after you plant it from seed. This means, around day 75 or so, depending on how the season was, you can start watching for ripe watermelon. How to pick a ripe watermelon will come to you; you just have to be patient. Growing watermelons is a wonderful thing to do, especially if you love fruit in the summertime.
