Step 1. Plant watermelon seed during spring once all danger of frost has passed in a location that receives full sunlight. Spread 3 inches of organic manure over the planting site and use a garden tiller to incorporate it into the soil to increase drainage and fertility.
Don't start seeds any earlier, because large watermelon seedlings transplant poorly. Plant 3 seeds in 3- or 4-inch peat pots or large cell packs, and thin to the best plant. Sow watermelon seeds 1/2 inch deep. Place in a sunny south-facing window or under lights to germinate.
