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.
Ideally, the seedless watermelon seeds should be planted in a greenhouse or the like with temps between 75-80 degrees F. (23-26 C.). Direct seeding in commercial enterprises is very difficult. Over seeding and then thinning is a costly solution, as seeds run from 20-30 cents per seed.
