Guide to the cultivation of watermelon, from choosing the right soil for spring sowing to harvesting of the fruit, after about four months from sowing.

The watermelon or watermelon, the Cucurbitaceae family, is native to Africa. It was grown on the banks of the Nile since ancient Egypt, as seen in several hieroglyphs and was introduced in Europe during the Christian era. The fruit of watermelon is red, crunchy, rich in sugar and water, and is therefore often used in low calorie diets. It may have spherical or oval and the size can vary depending on the species.

Climatic conditions

The ideal climate for the cultivation of watermelon is temperate – warm, not too rainy, because during the ripening of the fruit water can ruin the growth.

The soil should be light to allow the roots of watermelon, sensitive enough, to take root without any problems. Before sowing in late summer should be worked deep, dug by hand or with a cultivator to a depth of 35 cm.
