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.
Watermelon plants need lots of space to grow and spread out. If you start seeds directly in the ground, build mounds in your garden, spacing them 4 to 6 feet apart. Plant four to six seeds per mound; when the seedlings develop two leaves, thin them to two plants per mound.
