Fertilizing Watermelon. Wait until the vines begin to spread out before fertilizing your watermelon plants. If you're using a granular fertilizer, choose a balanced one like a 10-10-10 or 5-5-5. These three numbers mean that there are balanced amounts of nitrogen, potassium and phosphate in the fertilizer.
Work plenty of compost or organic slow-release fertilizer into the top few inches of soil in your watermelon patch. Mound the soil into small hills spaced 8' to 10' apart, less for compact varieties, and cover the hills with black plastic to increase soil temperature, maintain moisture, control weeds and speed growth.
