Growing Seedless Watermelons. If youâve enjoyed a delicious seedless watermelon, you might wonder how they are grown. It starts by treating watermelon seedlings with a chemical that makes the plant have 4 times (4X) their normal number of chromosomes. After planting, when this watermelon flowers, it receives pollen from a nearby normal (2X) watermelon. The result is a fruit that has seeds that are 3X .
Start the Seeds Indoors. Watermelon plants are very frost sensitive and exposure to cold temperatures can quickly kill them. Get a head start on the growing season by planting watermelon seeds in peat pots indoors approximately three to four weeks before the last frost date in your region.
