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.
Watermelons need a long growing season (at least 80 days) and warm ground for seeds to germinate and grow. Soil should be 70 degrees F or warmer at planting time. Sow seeds 1 inch deep and keep well watered until germination.
