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 .
Plant heirloom watermelon seeds in late spring; the plants thrive in summer heat. Sow the seed one-half inch deep outdoors after frost-season is over and soil is warm. Soil should be rich and well-amended with compost or manure. Sow the seed 12 inches apart, in rows 6 feet apart. They may be started indoors from seed no more than 2-3 weeks prior to setting-out date, and never let watermelon seedlings become root-bound in their pots.
