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 .
Although a warm-climate crop, watermelons can be grown in northern areas if you have the right variety. Icebox types like âSugar Babyâ, âYellow Dollâ, âTiger Babyâ, and âGarden Babyâ mature in 75 to 85 days, which should be enough time for a bountiful harvest. The larger watermelons typically take 85 to 95 days to mature.
