Generally speaking, watermelon is the favorite summer fruit.

It is refreshing, since it is composed of more than 90% water. We can consume it in salads, mix it in our cocktails, make it in water or consume it in slices.

But what is little known is that this fruit suffers from a serious identity problem. Some experts refer to it as a vegetable, while others consider it unmistakably a fruit. Who has the reason?

In reality, the confusion occurs because the watermelon is a cucurbit, which is why it is related to the cucumber and pumpkins.

It is grown as a fruiting vegetable and is generally treated as a vegetable for culinary uses.

However, it is considered a fruit because it develops from the plant ‘s ovary after flowering and contains seeds.

What is undeniable is its delicious flavor and its high nutritional value, which makes it a fruit that should not be missing from our regular diet.

Necessary conditions for planting watermelons

To plant watermelon we must pay attention to the following requirements:

The Nutrients

Watermelons are not very demanding in terms of nutrients, although it is recommended to put some homemade organic matter such as mature and well-decomposed compost in each hole where the seeds are sown or the transplant is made.

If you mix compost with some type of chip or sawdust it will be ideal.

the substrate

The watermelon is not very demanding at this point, but it gives better results in soils rich in organic matter, and well drained.

Substrate Tips

We will seek to plant watermelons in sunny areas and in soft and well-fertilized land.

Watermelons, for their growth, require a minimum of 6 hours of sun a day, but the shoots must be protected from the sun if it is very intense.

For planting on land, the soil is mixed with highly decomposed compost.

Spread it evenly over the planting bed to create a rich feeding area for the watermelon.

For this, the most suitable is 15 to 20 cm of well-tilled soil.

Remember:Remember that watermelons are demanding in terms of drainage, as waterlogging can cause root suffocation and fruit rot.

If your garden is prone to flooding, you need to do everything you can to fix it.

The watermelon plant expands a lot as it grows.

You can create slopes so water runs off to the side and install gutters to make it easier to collect water.

Another effective technique is to create mounds of soil and plant on them, so less water will accumulate at the foot of your plants.

At planting time, add a good amount of mulch, compost, peat or manure to fluff up the soil and aerate it.

If you also add river sand and mix it well with the soil, the result will be favorable.

In extreme cases, it is best to install a network of drainage pipes.

Keep in mind that if irrigation is excessive or very deficient, up to 50% of production can be lost, just like melons.

Watermelons grow best in soil with pH levels between 6 to 6.8.

Before planting watermelons

The seeds

The seed for planting watermelon is extracted from the ripe fruits. It is important that you choose the variety based on the space you have in your garden or where you want to plant it, as there are varieties that require a lot of space to grow.

Where do we plant them?

Preferably outdoors. With direct sun.

The watermelon is less demanding in temperature than the melon.

When the differences in temperature between day and night reach 20 to 30 ºC, imbalances are caused in the plants.

In certain cases, the neck and stems open, and the pollen produced is not viable.

land preparation

The soil must have good filtering. Also, it should be loose enough, without being compressed.

The soil provides your plant with the nutrients it needs, while the sand controls moisture.

Till the area where you are going to plant your watermelons.

Each mound must have 6 cms. tall. The ideal is that between each mound you leave at least 2 meters of separation.

Although they are fruits with a high water content, their water needs are actually low.

It is advisable to drip water them to prevent the leaves from getting wet, as they rot easily.

Tips on watering

Drip irrigation is ideal

They require daily but regulated irrigation, only to maintain soil moisture.

When the plants reach 8 cms. You must reduce the irrigation and do it every 3 days, just making sure that the soil does not dry out completely.

Keep foliage and nuts. You can put the fruits on a clean piece of wood, a large smooth stone, a brick, etc.

On very hot days, the leaves may wilt, even if the soil is moist.

If the leaves continue to fall the next day, water them with plenty of water.

Watermelons get sweeter if you stop watering a week before harvest. After the harvest, water regularly again to favor the next harvest.

Did you know…Every part of the watermelon is edible, even the seeds and the rind.

The first shoots

On average, the seeds take between 5 and 15 days to germinate.

When the first plants have sprouted, we will uproot the weakest and leave only the healthiest and most vigorous plant.

the transplant

The transplant from the seedbed to the final site will be done when the plant reaches about 15 cms. Tall.

Put some decomposed compost in each place where you transplant the plant.

A good idea is to cover the rows with netting to keep them warm and protect them from insects.

Did you know…In Japan they grow watermelons in square cubes so that the fruit adopts this shape. This is done with the intention of storing them more easily.

watermelon pruning

Pruning watermelons is important to maximize fruit production and improve yields.

But… how should we do it?

There are several methods. However, we recommend one that gives good results and is simple.

It consists of removing all the shoots of the watermelon, except for the two most vigorous.

La cosecha y recolección

Las sandías estarán listas aproximadamente a los 4 meses de cultivo

El tiempo de recolección se determina por los siguientes síntomas externos:

  • El zarcillo rizado que se forma cerca del tallo está completamente seco o la primera hoja situada por encima del fruto está marchita.
  • Al golpear el fruto con los dedos se produce un sonido sordo.
  • Al rayar la piel con las uñas, ésta se separa fácilmente.

Asociaciones favorables

Se asocia muy bien con el maíz y con las acelgas.

Además, puedes sembrarlas con espinacas, guisantes, rabanitos, coles, judías, ajo, cebolla, puerro y lechugas.

Asociaciones poco favorables

No combina bien con el pepino, ya que terminan compitiendo por el espacio.
