Refreshing Summer Fruit and Its Multiple Benefits

Watermelon is one of the most famous summer fruits and the most widespread around the world, due to its sweet taste, important nutritional value, and high ability to hydrate the body in hot weather. Watermelon belongs to the Cucurbitaceae family, and is cultivated in vast areas of the world due to its ability to adapt to warm climates.

First: The Concept and Origin of Watermelon (In Detail)

Watermelon is a large summer fruit belonging to the Cucurbitaceae family, the same family that includes pumpkin, cucumber, and zucchini. Watermelon is characterized by its thick green rind and its red or yellow flesh full of juice, in addition to containing a high percentage of natural sugars that give it its sweet, refreshing taste.

Watermelon is considered one of the fruits that humans have relied on for thousands of years. Historical discoveries have indicated the presence of traces of watermelon seeds in Pharaonic tombs in ancient Egypt, indicating that humans have been cultivating it and relying on it for food since ancient times. Scientists suggest that the original home of watermelon is in the southern regions of Africa, where it grew naturally in desert and semi-desert lands, then humans began cultivating it and developing its varieties over hundreds of years.

Over time, watermelon spread from Africa to the rest of the world through trade and travel. In ancient times, traders transported it to the Mediterranean region, then to Asia, especially India and China, where its cultivation developed and China today is one of the largest producing countries. With the development of agricultural methods, watermelon varieties, colors, and sizes diversified, so red and yellow types appeared, large and small types, and even seedless varieties.

Today, watermelon has become one of the most widespread fruits in the world, not only for its delicious taste but also for its high nutritional value and ability to hydrate the body, making it one of the most important symbols of summer in various cultures.

Seventh: Watermelon Cultivation

Watermelon is an important summer crop, characterized by its ability to grow in relatively warm and dry climates. Its cultivation requires good knowledge of soil, climate, and plant care methods to ensure a bountiful and sweet-tasting harvest.

1- Suitable Soil

• It is preferable to plant watermelon seeds in fertile, light, well-drained soil.
• Sandy or light loamy soil is ideal because it prevents water accumulation around the roots, reducing the risk of plant rot.
• The soil should be rich in organic matter to ensure plant nutrition from the start.

2- Climate and Temperature

• Watermelon needs direct sunlight for long periods daily.
• Ideal temperatures for plant growth range between 20–30°C.
• Very low temperatures delay plant growth and affect fruit taste.

3- Planting and Seedlings

• Seeds are planted directly in the field after the frost ends or in the warm season.
• Seedlings can be started in a nursery and then transplanted to the field after growing.
• Sufficient spacing should be left between seedlings, often 1–1.5 meters between plants, because the stems spread on the ground.

4- Irrigation

• Watermelon needs a large amount of water, especially during fruit growth and filling stages.
• Drip irrigation is preferred to conserve water and prevent root rot.
• Irrigation is reduced as harvest approaches to improve fruit sweetness.

5- Plant Care

• Remove weeds around plants to preserve nutrition and moisture.
• Support the plant if necessary to prevent stem breakage.
• Monitor pests and insects that may attack leaves or fruits and use appropriate pesticides if needed.

6- Ripening and Harvest

• The fruit begins to grow and fill about 70–90 days after planting, depending on the variety and climate.
• Fruit ripeness can be identified by:

The shiny rind color characteristic of each variety.

The hollow sound when tapping the fruit (a hollow sound indicates ripeness).

The drying of the stem connecting the fruit to the plant.

Watermelon cultivation is a precise process requiring patience and attention to nutrients and water, but it leads to obtaining delicious and hydrating fruits that are very popular worldwide.
