well in any part of the country. However, the crop tends to thrive better in

When picking a site, you should note the kind of soil on
the site as watermelons thrive in sandy or loamy soil. The crop also occupies a
large amount of space, so you might want to pick large site depending on the
amount you wish to cultivate.

The ideal planting period for watermelons is at the start
of the rainy season or towards the end of the season. Although the crop can be
planted at any time as long as there is adequate water supply through

Part of Nigeria

is usually May and/or July.

Part of Nigeria

It is well known that the Southern part of the country
experiences more rainfall than the North, and it is important you avoid
planting during the time of rains. The ideal planting period for this part of
the country is in the months of March, Late June or early July and September.


Watermelon plants have many varieties which gives you
several options to pick from. However, the most popular varieties of watermelon
are the Congo and Crimson Sweet varieties.

If you are not sure about the quality of a watermelon
seed, you can check them by dipping them in a 3 – 5% solution of salt. The
seeds that sink to the bottom of the solution are termed well enough and can be
prepared for sowing.

You can also enhance the immune system of the plants by
drying the seeds under the sun for a week prior to planting.

Watermelon Farming Techniques – Planting Operations


The site is to be ploughed before the watermelon seeds can
be planted. The seeds can be planted the same day the land is ploughed or the
day after.

Watermelon can be planted either on flat land or on ridges
depending on the soil type and the number of watermelons to be planted.
Planting on ridges is advisable for clayey soils and if you desire to grow them
in commercial (large) quantities. However, the soil should be well drained as
watermelon plants can’t thrive in water-logged environment which makes it futile
to plant during the rainy season.


The method of planting depends on the variety you are
going for. Generally, the plant rows should be 2 metres apart and spaced 1 foot
apart. Some varieties of watermelon will require more space such as the Congo
or Crimson Sweet which ridges should be at least 10 feet apart.

When planting dig a hole of depth 30cm and diameter of 1m,
you can make about 10 holes in one ridge and plant one seed per hole.


Post-planting operations include adding manure, watering
and checking the plants from time to time for signs of growth, maturity and
pest and disease infestation.

When adding fertilizers or manure, it is advisable to add
humus rather than fresh/organic manure which often affects the taste of the fruit
and weaken the resistance of the plant to disease infestations.

Inorganic fertilizers like Potassium and Phosphorus should
be added as they improve quality of the fruit and hasten to ripen. Also, during
early growth the plants require high levels of nitrogen, however, you should
reduce the supply once the plant flowers and fruits.

Irrigation should be done once a week until the plants
become mature; you can also increase the humidity of the soil by adding mulch to
the soil. Mulch doesn’t only increase the moisture in the soil but also prevent
weed growth


The watermelon is attacked by one main pest known as the
leaf-eating beetle. The beetle feeds on the leaves of the plant thereby disrupt
its growth. You can easily get the plant to recover from the attack by simply
improving soil conditions of the plant and the plant will fight off the
infestation itself.


Mildew is a fungus that also affects the leaves of the
plant. Overhead watering and allowing the leaves of the plant to stay wet for
too long can lead to the disease. To prevent the disease simply avoid overhead
watering and dry the leaves of the plant in due time.


Watermelons take about 3 months to mature and then they
are ready for harvest. There are several signs of maturity or ripening you
should watch out for which includes drying of the tendrils, uniform colour, a
dull sound when flapping the fruit and also a crackling sound at the rind when
pressure is placed on the watermelon.

Colour changes will also signal maturity, as a watermelon
ripe for harvesting will have a yellow color at the part closest to the soil.

To Harvest Watermelons

Simply cut the stem with a sharp knife close to the fruit.

Once harvested, you can simply move them to specific delivery points and to the hands of the final consumers.
