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 .
If you have a seedless watermelon type, you'll need to plant a seeded type nearby that blossoms at the same time for proper pollination and fruit set. Watermelons should be watered deeply, about 1 to 2 inches per week, as well as more during a drought or high heat. Be consistent especially during fruit development.
