Due to present in the variety of cubic, square, and pyramid shape, they are pricy to purchase rather than the original shaped one. This shaped type of watermelon only belongs to the wealthy class of the consumer or buyers.

Watermelon cultivation can be done in numerous ways according to its harvest time and weight.     

The Carolina cross produced the heaviest watermelon 29to 68 kilograms in about 90 days.

The little golden person takes 70 days from sowing to harvest. 

Orangelo weight 9 to 14 kilogram and take 90 to 100 days till the fruit harvest 

Cream of Saskatchewan grows in cold climate and harvest in 80 to 85 days

Moon and star are weighing 9 to 23 kilograms and harvest in 90 days 

Densuke watermelon is firstly harvest and weighing 11 kgs

Melitopolski is highly cultivated in the region of Russia and take 95 days to harvest

watermelon farming

Watermelon farming in horticulture shows a variety of improvements for the production of watermelon. Its hard crust made it more accessible to transport it from one place to another due to its oblong shape as well. Improvement in geographical conditions also provides to get an elastic environment for the cultivation of watermelons.

Watermelon is the garden-variety fruit that every grocery sells more often. China is the largest producer, and more than 40 states of the United States are cultivating watermelons. It is a smaller shaped variety of melons known as icebox melons as they have red and yellow color flesh. 

Some of the groups are also seen in the variety of watermelon, which shows the variation in taste and texture of its flesh.

·        Citroides group is a fleecy melon cultivated in the world for fodder with sweet yellow flesh.

·        The Lanatus group is food for the traveler in the Kalahari Desert. Seeds are edible in this group and having juicy white meat. 

·         Vulgaris group is widely cultivated for the consumption of human and cattle feed as well.

Watermelon is mainly consumed in summer; it contains water more than 85%, and the rest is sugar with low-fat properties. It mixes with other fruit juices, wine, or pickles. Watermelon seeds are also consumed by a human after the roast and dried up.

In China, people consume seeds of watermelon on the eve of china new year, and in Vietnamese, people consume seeds as a snack on the Vietnamese New Year holiday.

Watermelon zest has vile flavors, which is used in making pickles, and people were making vegetables by stewing and stir-frying. Watermelon zest produces Amino acid citrulline.

Only vitamin c present in a significant amount and a low amount of nutrients with 30 calories per 100 grams of serving. It is also known as state vegetable or fruit in Oklahoma State due to its versatility of consumption. 

Watermelon Farming Through Seeds

Watermelons grow from seed. You might be tempted to use seed from a melon you purchased, but it would just be time wasted. There are chances of it being a hybrid one. Hybrid is somewhat different from crosses not true to nature. Then, you would probably end up cultivating what is generally termed as pig-melons, which is nice to feed pigs only and not human beings. 

What Kind Of Seeds To Buy For Watermelon Farming?

If possible, pick the open-pollinated heirloom variety of seed, if necessary. You will find far better and fascinating types in the heirlooms than in the regular collections at the local gardening center. 

Start your watermelon seeds in the field, where they will spread. To germinate, the soil should be at least 18 ° C.

 What Is The Right Approach To Watermelon Farming?

Do NOT plant your watermelon seed in a container or big bowl, unless you have an incredibly short growing season. Neither buys watermelon seedlings from a nursery. Watermelon seeds germinate within a few days, simply and rapidly. 

Watermelon plants quite quickly outgrow the seedling stage and do not like transplantation. You don’t save a great deal of time, and you end up with a poorer vine.

Avoid all this needless hard work and stick your seeds in the dirt, about 2 cm or an inch deep.

Watermelon Vines Need A Lot Of Care

The watermelons need soils that are dark, warm, and permeable. It allows the land to develop melons. There are some benefits of growing the soil: A slab or hill is free draining. If you have thick clay dirt, bring the bed certainly up.

Mounds are beautiful even when the soil is somewhat unfortunate. To raise watermelons, make a mound of healthy soil with plenty of compost in it. Often, after using much of the compost, farmers plant them in what’s remaining over from a compost pile.

When you want to grow stuff in tidy circles, or if you’re going to plant a broad field, raise watermelons on ridges, much as the growers do.

 The Benefit Of Mulching

Watermelon cultivation needs to be very diligently done. A few things like mulching that one needs to keep in mind. Melons have deep roots and require plenty of water. Therefore, you need to ensure that the field is never dry out, in case it dries, so mulch helps. 

Mulch holds weeds down. Weeding may disrupt the strong roots, so it’s best not to let them rise. Watermelons are starving animals. 

If your mulch is like compost or old animal manures, it’s excellent. Watermelons can tolerate relatively fresh manure and fertilizers. 

Otherwise, periodically feed the watermelons with anything like pelleted manure or other sustainable fertilizer.

Once the vines are two meters thick, pinch the ends. Encourage branching. When your watermelon vines get bigger, they seek to take up more space. Unless they start smothering specific stuff, you should warn them to keep to their region by smoothing the ends of the vines, so they develop in the right direction.

Watermelon Harvesting

For cultivating watermelon, it requires a heavier feeder than the other fruits. Before planting, the soil has to be compost and manure was rotted in it to provide the warmness to the sown seeds. 

Sown seeds start growing in the form of fruit; then fertilizers were mainly starting dressing up side by side. It requires a ph scale of 6 to 6.5 and more than 80 days of the warm summer season to grow up.

It is a fragile fruit to time in sandy, muddy soil. The soil will be moist, and water needed in the field will be 1 to 2 inches per week. Watermelon farming soil contains a high amount of nitrogen, phosphorus, and potassium, but after illuminating it into flowers, it needs less nitrogen for further growth. 

Watermelon elevates in a row sun-dried atmosphere, as they are not much sweeter as they are ripe, so the harvesting part plays a vital role in the life span of watermelon. The texture and color of a watermelon show whether the fruit is ripe or not.

Pests of Watermelon: 

The leading watermelon killer is leaf-eating beetles (also destroying the flowers), including painted and dotted flea beetles, pumpkin beetles with or without markings, whatever you call them.

They all look alike, all doing the very same: nibble away on your watermelon plants. However, if they are a significant concern, it’s just an indication that your watermelon is stressed.

In a safe climate and decent soil, stable watermelon does not draw so many beetles. A watermelon should also grow quickly enough to manage any beetles.

The other primary concern with rising watermelons is mildew, a disease that makes the leaves appear like white dust. Fungus thrives in wet environments.

In the tropics, you may not be able to avoid beetles or mildew until the rainy season build-up starts. And it’s not worth it anyway… 

The unbearable heat and humidity aren’t healthy produced watermelon conditions. Develop anything that needs rain, waiting for another dry season to produce watermelons.


In this guide on how to do watermelon farming, we have tried to explain all those steps and techniques that are required to produce a quality crop. However, you are solely responsible for crop failure for any reason. Don’t worry, this is not a kind of alarming signal. It’s just a precautionary statement. In the end, we would like to advise you to take any watermelon farming-related decisions at your discretion.  

Blossom End Rot On Watermelons

The watermelon plant belongs to the Cucurbitaceae family that produces flowers. It produces delicious fruits that are eaten worldwide and are full of nutrition. But it can be affected by various harmful diseases.

Blossom end rot is also one of them. This piece of content provides detailed information on Blossom End Rot on Watermelon. 


  • The appearance of the burned portion of the fruit of the watermelon plant. 
  • Formation of light brown spots that turn into lesions that darken and dry over time. Sunken leathery spots are also visible. 
  • Decaying of fruits at a fast rate. 

Although the disease is not contagious, the removal of infected plants is a must. 

Causes of Blossom End Rot On Watermelons

  • Water is taken into plants through their root system. It is utilized by plants and some of it evaporates. Water evaporates from the leaves of plants. This situation occurs when the sun warms up the plant surface. Water from leaves transpires and more water takes its place and thus the plant does not burn. The leaf surface is smooth, water movement from other parts to leaves is easy and quick.

On the contrary, fruits have harder skin. Thus, the movement of water is not fast as the pull of water is slow. 

Therefore, the bottom portion of the fruit deprives moisture and burns. It usually darkens or appears shriveled. Decaying also starts occurring eventually. More organisms like insects can attack easily. 

  • Imbalance in Ca levels is also a major cause of blossom rot in watermelon. Ca is immobile relatively. But due to heavy transpiration Ca be moved to leaves in high amounts making fruits deprived of them. 

Prevention of Blossom End Rot On Watermelons

Soil conditions

Proper soil conditions are so important to ensure healthy growth in plants. In case the soil fertility of your planting site is unfit, a variety of diseases and abnormalities are bound to occur. Infected plants are of no use and even distracts from a healthy crop. 

Therefore, getting your soil tested is highly recommended. It will aware you of things that your soil has more or what it lacks. Moreover, it is important to know the pH level of the soil. 

All you need to do is, take a small sample of soil and take it to the nearest lab for agricultural testing. It will provide you proper details about the nutrient level and pH level of the soil. 

This will make sure you provide only necessary nutrients and do not overdo it. 

In the case of watermelon, 6.5 on a pH scale is perfect for its growth. Anything above or below will lead to complications. 

Fall is a perfect time to test the soil before sowing watermelon seeds in the spring season.

Next, if the soil lacks in Ca, it leads to blossom end rot in watermelon. After checking soil 3 months before planting, add lime to the soil to overcome Ca deficiency. 

Get the soil tested every 3 years for proper growth. If soil is problematic then annual testing is suggested.

Keeping the soil moist at all times with proper and regular watering is a must to avoid this disease. 

The water content of soil changes and keeps fluctuating from dry to wet at times of watermelon blossoming is inadequate. This can lead to melon blossom end rot in watermelons. 

Irregular watering leads to uneven intake of Ca by watermelon plants. 

However, this disease can be caused even when there is a proper amount of Ca. if there is improper water at the time of fruit formation or blossom developing. 

To avoid disease, 1- 1.5 inch water level should be provided during fruiting periods. 

Nitrogen Content 

If nitrogen is present in limited amounts in soil, blossom end rot can occur possibly. 

The work of nitrogen is to increase the size of leaves in plants. If nitrogen is found in an improper amount, the size will be affected obviously. 

Due to this, more Ca is directed towards fruits. This leads to an imbalance in Ca amount and causes Blossom end rot. 

Watermelon rotting on Vine

Watermelons rotting on the vine are possibly visible in conditions like Blossom end rot, Belly Rot, Gummy Stem Blight, Bacterial Fruit Blotch, and Rind Necrosis. 


  • Watermelons should be planted in well-drained soil to ensure proper watering and moisture conditions. This ensures plants develop a deep and large root system to absorb healthy amounts of Ca from the soil. 
  • Mulch can also be used to retain moisture in the soil. It compresses weeds too. 2-4 inches of mulch is perfect for watermelon plants. It holds moisture in the soil by blocking evaporation. 

Watermelon Growing Problems

Growing watermelon is not a piece of cake. It comes with problems. There can be watermelon plant problems that affect fruiting and render plants useless. 

Few diseases and abnormalities are mentioned below-

  • Leaf Curling- leaves curl under and turn yellow. They get deformed and can be easily identified. Aphids are tiny, oval creatures that reside on the underside of leaves and lead to this abnormality. It releases a sticky substance known as Honeydew. It is advised to use insecticidal soap. 
  • Leave discoloration- leaves start turning yellow, pale green, or brown. Spider mites can be a possible reason behind this. Spraying water can help in getting rid of such insects. Infected leaf removal can be better as it protects the whole plant. 
  • Tunnels on leaves- Trails or tunnels are observed on leaves. It is caused by leaf miner larvae. Cultivate a garden to decrease this disease occurrence. Larvae get destroyed upon cultivation. 
  • Water-soaked blotches- leaves get infected and suffer from the appearance of water-soaked blotches. Angular leaf spots can appear which turn yellow or crisp. Pruning leaves infected by this disease can prove helpful. Do not wet foliage much as wetting leads to disease. 
  • Bitter Fruits- inadequate pollination can cause bitterness of fruit and misshapen fruits. Dry soil and high temperatures also lead to this condition. Poor soil fertility is disastrous. 


Blossom end rot is a harmful condition in plants that destroys fruit and makes them inedible. Infected fruits cannot be treated to turn them into healthy ones. But, prevention is better than cure.

Therefore, following the preventive measures mentioned above can assure you healthy and edible fruits of melon.
