The watermelon is extraordinary and great fruit, perhaps one of the largest among all existing fruits. To give you an idea, under normal production conditions, your weight can vary between 10 and 20 kg of pure water.
By seeds, in August in regions of rigorous winter, also grown in greenhouses in a colder climate, in other regions in any part of the year. Melancia Prefers silica-clayey soils, deep and rich in organic matter. Harvesting is done about 100 days after planting.

Planting Watermelon: Soil and Planting
In general, the watermelon presents the better development and greater productivity in light soils and good fertility. Soils subject to waterlogging should not be indicated. saline and shade.
The soil should be well-drained, light, fertile, with good availability of nitrogen, rich in organic matter, with pH between 6 and 6.8. Sandy soils are the most suitable.
Sowing of the seeds is done directly at the final site if climatic conditions are adequate. Otherwise, the seeds can be sown in 10 cm diameter pots or in seed bags, which are kept in warm places.
The seedlings should be transplanted carefully when they reach 10 to 15 cm in height. At the definitive site, pits of 30 or 40 cm in diameter and depth are opened, with the soil removed, fertilized and replaced, closing the pit again. Then the seeds can be sown to a depth of 2 to 5 cm, leaving up to six seeds per pit, and then the weaker seedlings are removed to leave only two or three plants per pit. Seed germination usually takes between 4 and 14 days. The spacing can range from 2 to 3 m between pits.
Plant watermelon: Irrigation and Fertilizers
The soil should be kept moist during the growing phase of the plant. During the growth and maturation of the fruits, a decrease in the frequency of irrigation can favor the production of sweet and tasty fruits. For irrigation help, We recommend our low-cost irrigation and labor page
Before planting your watermelons, stir in the soil 10 cm of organic composite material. Cow manure, peanut shells or cottonseed residues provide the soil with the necessary nutrients for growing watermelons. The soil also needs a fertilizer with formulas 10-10-10 or 16-16-8 which represent the proportions of nitrogen, phosphorus, and potassium (NPK), respectively. Apply 4 to 6 cups for every 30 m of a row of plants.
Soak the watermelons with fertilizer NPK 20-10-20 until the vines begin to bloom. Carefully follow the instructions on the fertilizer package to use the correct quantities. Switch to fertilizer in NPK formulation 20-20-20 when the vines begin to bloom and continue to use it throughout the growing season.
Addition of nitrogen
Watermelons need 0.45 g of ammonium nitrate every 30 m, or 0.9 g of calcium nitrate per 30 m of row of plants. Provide nitrogen to your watermelons before the vines start to grow, and repeat after the fruit begins to develop. Do not give them too much nitrogen. Doing so will decrease the amount of fruit produced. Avoid putting nitrogen in the leaves, as this will cause burns.
