To prevent Nitrogen burn, blend the fertilizer with the top six inches of soil. Compost helps in enhancing the soil structure, adds micronutrients in the mix and helps in water retention.
You can also add mulch around the Watermelon plants to improve moisture retention, prevent weed growth and add Nitrogen-rich organic matter to the soil.
When feeding Watermelons with granular food, do not let it contact with the leaves. The leaves are sensitive, and you could harm them.

A new seedling Watermelon has different nutritional needs. While in the stage of bloom, the requirements are different too.
For starter, use nitrogen-based fertilizer. When you see the Watermelon plant starts flowering, feed the Watermelon with Phosphorus and Potassium-based fertilizer.
Citrullus Lanatus plant requires rich both fertilizer for optimal fruit production.
How often to fertilize Watermelon?
Feed the watermelon plant one time every week, preferably with a liquid soluble fertilizer. Apply a 20-10-20 NPK formulation of compost until the flowers of the plant bloom. When you notice the flower bloom, use a 20-20-20 fertilizer for the rest of the growing season.
What is the best environment for Watermelon?
To plant Watermelon seed, you need fertile and well-tilled soil. Generate soil amendments with compost and manure to raise the nutrient level in the ground.
You can add sharp sand for proper drainage. You may consider applying a slow-release fertilizer into the soil. This practice will add a continuous boost of nutrients.
Slow-release fertilizer reduces your maintenance and labour during the growing season. Add food plant right before planting these seeds.
Place your Watermelon in a site with full-sun exposure. The best location would be a warm and humid micro-climate.
Place the plant in the south-facing wall of a house. The young plants and seeds will require a minimum of one inch of water per week to keep the soil uniformly moist.
How to plant from Watermelon seed?
Watermelon seeds need to be located outdoors in the spring. These seeds can be placed up to twenty days indoors before planting in the garden. Never start sooner because large watermelon seedlings do not transplant well.
