The watermelon is one of the world’s most popular summer fruits — and not without reason: its high water content, sweet taste and vivid red flesh make it the perfect snack on hot days. But the watermelon can do much more. It is full of healthy nutrients, versatile in use and can even be grown in your own garden. In this article you will learn everything about origin, variety, nutritional values, cultivation and creative ideas with watermelons.
Origin and history of the watermelon
The origins of the watermelon (Citrullus lanatus) lie in Africa — more precisely in the arid regions around the edge of the Kalahari Desert. Wild melon species that served as water reservoirs grew there thousands of years ago. Watermelons were already cultivated in ancient Egypt and placed in tombs as provisions for the afterlife. Through trade and colonization the fruit spread to Europe, Asia and eventually to the Americas. Today the watermelon is grown worldwide — from Spain via Turkey to China, which is now the largest producer.
Variety — not only red and round
The classic watermelon is green on the outside with light stripes and bright red inside. But the variety is far greater: there are round, oval and elongated types. In addition to the typical red flesh there are also yellow and orange varieties. Some cultivars are low-seeded or even seedless, which makes them especially popular for children or for processing. Well-known varieties include ‚Sugar Baby‘, ‚Crimson Sweet‘ or ‚Yellow Doll‘. Mini watermelons weighing only 1–2 kg are also enjoying growing popularity because they are particularly handy and space-saving.
Nutritional values and health benefits
Watermelons consist of around 90–95 % water and are therefore extremely low in calories — ideal for hot days when you want to refresh yourself and do something good at the same time. 100 grams of flesh contain only about 30 calories. In addition, they provide valuable vitamins such as vitamin C, A and various B vitamins.
Growing watermelons in the garden
Anyone with sufficient space, sun and patience can also grow watermelons themselves. They need a warm, sunny location and a loose, humus-rich soil. Cultivation works best in a greenhouse or polytunnel, but good results are also possible outdoors in the warm regions of Central Europe.
Sowing takes place from April indoors or from May directly into the bed. The plants require a lot of warmth, water and nutrients — regular watering and fertilizing is essential (the universal fertilizer or the vegan fertilizer from ARIES is recommended here). Important: Do not water from above, but directly at the root to avoid fungal diseases. It takes around 80–100 days until harvest. You can recognize a ripe melon by the dull sound when tapped, a yellowish spot on the rind (resting spot) and a dried-out fruit stem.
Storage and Shelf Life
A whole, intact watermelon will keep at room temperature for up to two weeks. Cut fruit should be stored wrapped in cling film or in a container in the refrigerator and consumed within a few days. The riper the melon, the more perishable it is — especially at high temperatures.
Use in the Kitchen
The classic option: enjoy watermelon in slices or cubes — fresh, juicy and refreshing. But the melon can also be used creatively in the kitchen. How about a fruity summer salad with feta, mint and cucumber? Or a watermelon smoothie with lime and mint?
The sweet flesh is also excellent as a base for sorbets, cocktails or ice pops. In Asian countries the rind is also cooked and used as a vegetable side dish — sustainable and surprisingly tasty.
Watermelon as a Decorative Highlight
Thanks to its size, color and versatility, the watermelon is not only tasty but also visually striking. Especially at summer parties it makes an impression as a carved fruit bowl, „watermelon punch“ or as a fruit skewer. Children also love melons cut into star, heart or animal shapes — punched out with cookie cutters.
A popular trend is the „melon cake“: the flesh is cut into a cylindrical shape and decorated with fruit, yogurt or cream — ideal for healthy birthday cakes without baking.
Enjoy Healthily — but in Moderation
Despite all advantages: the amount matters with watermelons as well. Due to the fruit sugar content, excessive consumption can cause flatulence or stomach complaints in sensitive individuals. Diabetics in particular should monitor the sugar content. But when consumed in normal portions, watermelon is an ideal component of a balanced, summery diet.
Watermelons and Sustainability
When buying, you should — if possible — choose seasonal produce. Look for organic quality if you want to avoid pesticide residues. The rind should be firm, intact and evenly colored.
Another advantage: the melon is almost entirely usable. Not only the flesh, but also the seeds and rind can be used – for example roasted as a snack or pickled as a vegetable.
Conclusion
The watermelon is far more than just a refreshing snack – it is a versatile, healthy and visually appealing fruit that should not be missing from any summer. Whether eaten plain, in a salad, as a beverage or as a dessert: the melon brings color, freshness and enjoyment to the plate. With a little patience it can even be grown in your own garden. Pay attention to quality and origin when buying – and enjoy the fruit of summer in all its facets.
