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 .
