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.
Boosting the soil's fertility levels before planting watermelon seeds ensures quick germination and seedling establishment. For the best results with watermelons, use 3 pounds of 5-10-10 fertilizer for every 100 square feet of planting space.imply scoop the seeds out of a watermelon, rinse them under water to remove any fruit pieces or fruit juices, and let them air-dry on a paper towel. In general, watermelon seeds stay viable for approximately four years. However, the longer you wait, the lower your chances of optimal germination.
