The ecological cultivation of watermelon

Do you dare to grow watermelon? Well, in this post you will have the most relevant and useful information for you to harvest beautiful organic watermelons.

And if you want to know the nutritional benefits that eating watermelon brings us, I leave you the link to my post on the Properties of watermelons .

What is watermelon?

The watermelon (scientific name Citrillus vulgaris ) belongs to the cucurbit family . Watermelon is a creeping annual flat that can be sown from January or February (protected sowing), and in about 4 months it can be harvested in a staggered manner.

It is a fruit similar to melon .

They need an approximate space of 1.5 meters between plant and plant.

It also grows very deep roots, so if you want to grow watermelon in pots or containers make sure they are deep enough.

As with any other vegetable, fruit or ornamental plant, when growing watermelons try to opt for local varieties of watermelons. They are already adapted to the climate and are less prone to pests and diseases.

 

How to grow organic watermelon .

Seeds

Don’t play it, try to use the best seeds you can find. Betting on a good seed is betting on a good start. If you need quality seeds, here you have Organic Seeds .

They will save you time and money and you will have better results.

Soils

For the correct development of watermelon it needs loose and spongy soils, well aerated that drain the water well to avoid puddles and that are slightly basic.

Weather

Watermelon prefers warm climates and needs a minimum of 5 hours of sun to thrive properly. The optimum temperature for its development is between 22 and 28 ºC

Irrigation

You need the supply of water regularly and frequently. The more advanced the development of the plant, the greater the need for water, being the period of greatest need from the appearance of the fruit to its maturity.

The best way to water is through drip irrigation, so we save water and avoid fungal pests. It is also very useful to help maintain some constant moisture in the soil with the help of mulching .

Subscriber

We must provide well decomposed compost at a rate of about 3 or 4 kg of compost per square meter

Special cares

It is important to avoid that the watermelons are directly in the ground during their development so that they do not develop rottenness. It is advisable to put a padding that on the one hand will help to maintain a good temperature and humidity in the soil and on the other it will prevent the fruits from being always wet.

Pruning is another work that can promote a good harvest and fruit formation. It is first done when it is about 20 cm high and has several side branches. Then what we will do is cut with the pruning shears the main branch in the center and we will leave the side branches.

In a second pruning, we will cut the end of the side branches, which we previously left in the first pruning, starting from the third or fourth leaf.

Finally, in the third pruning, the main branches are cut again, leaving between 3 and 5 leaves. These prunings are done so that we obtain crops with good-sized fruits, otherwise we would obtain many watermelons, but small ones.

The plant can be tutored as the fruits grow so that they are not in the ground.

Rotations

Do not repeat in places where we have grown other cucurbits (pumpkins or squash, zucchini, melon, cucumber, chayote, etc.).

Favorable associations

It would be a good idea to plant watermelons together with:

Spinach, peas, radishes, cabbage, beans, corn, garlic, onion, leek, lettuce

Unfavorable associations

Avoid growing watermelons with other vegetables in the botanical family of cucurbits.

Pests

Sometimes fungi appear if the aerial parts of the plant also get wet when watering. They can also be seen attacked by pests of thrips, whiteflies, aphids, mites, gray caterpillars and wireworms. There are many ways to avoid and combat them in an ecological way, see here

When to harvest

We must pay attention to the leaves that come out of the peduncle, which is the area where the watermelon joins the plant. When these leaves are dry it will be a good time to harvest the watermelon.
