How to harvest and store watermelon?

Watermelons are generally ripe and ready to harvest when the underside turns white to yellow and at least three tendrils are dead on each side of the melon. Harvest the watermelon 85 to 90 days after sowing the seeds, 35 to 45 days after flowering.

When to harvest watermelon?

There are several ways to tell when a watermelon is ripe and ready to harvest:

  • The fruit is the size you expect it to be at harvest.
  • The size varies according to the variety.
  • The tendril closest to the fruit begins to wilt, turn brown, and twist.
  • If the tendril is green, the fruit is not ripe.
  • If the tendril is dead, the fruit is either overripe or overripe.
  • The bark or skin loses its vibrant color and shine and becomes dull and there is little contrast between the stripes of the skin.

On the underside of the fruit where it touches the ground, there is a large oval spot of white, cream or yellowish color. The color of the soil stain when ripe will vary depending on the variety. When you touch the fruit, you hear a low punk sound or a rumble. Raw melons make a loud pinging sound when wrapped.

Watermelons on a single plant usually ripen in a period of two weeks. When the first melon is ripe, the second ripens quickly. When the tendril closest to the fruit turns brown and dries, the harvest will arrive in about a week.

A week before harvest, reduce watering enough to prevent the vine from wilting. Removing the water from the melon will concentrate the sugar in the fruit. Too much water dilutes the sweetness. In cool summers, the ripening process can be very slow and will increase the number of days to harvest.

Watermelon harvest

  • Harvest a watermelon by cutting the stem with a garden pruner or sharp knife.

  • Harvest the watermelon by cutting the stem with a garden pruner or sharp knife near the fruit.
  • Handle fruit carefully to avoid bruising and breakage.

Refrigerate watermelons immediately after harvest to remove heat from the field and extend shelf life. Store melons in a cool, shady place or put on ice.

How to store watermelon?

Watermelons can be stored uncut and unrefrigerated for about 10 days to 2 weeks. Store in a very cool place to extend storage time. If cut, the watermelon will keep tightly wrapped in plastic in the refrigerator for about 4 days.

Watermelons will rot if kept below 50 ° F (10 ° C) for more than a few days. Do not store watermelons with apples or tomatoes that release ethylene gas. Watermelon rinds exposed to ethylene will become thin and mushy.


Watermelon in Sudan from Kordofan Melon, New Genetic Study Suggests. Scientists have sequenced and analyzed the genome of the Kordofan melon (Citrullus lanatus subsp. cordophanus). Watermelon Was Domesticated in Sudan from Kordofan Melon, New Genetic Study Suggests. A Sudanese form of melon with nonbitter whitish pulp, and found that the subspecies is the closest relative of domesticated watermelons (Citrullus lanatus subsp. vulgaris) and a possible progenitor.

Watermelon in Sudan from Kordofan Melon

A Kordofan melon (Citrullus lanatus subsp. cordophanus) from North Darfur, Sudan. Domesticated watermelon is among the 10 most important crops in Central Asia, and knowing its geographic origin and potential progenitor would help targeted breeding efforts.

The geographic region of its domestication has long remained unclear with competing hypotheses favoring southern Africa, West Africa, and Northeast Africa, especially the Kordofan region, a former province of Sudan bordering North and South Darfur, and part of the western Sahel savannas.

Besides Citrullus lanatus, the genus Citrullus contains six other species, of which four (Citrullus amarus, C. ecirrhosus, C. naudinianus, and C. rehmii) are native in the Namib-Kalahari region, one (Citrullus mucosospermus) in West Africa (Benin, Ghana, and Nigeria), and one (Citrullus colocynthis) in northern Africa to West India.

All wild species have white pulp that cannot be eaten raw due to the presence of bitter terpene compounds. Only fruits of Citrullus mucosospermus are sometimes not bitter but instead bland tasting; the large, soft seeds of this species are used in West African ‘egusi’ stews.

Washington University

Based on DNA, we found that watermelons as we know them today with sweet, often red pulp that can be eaten raw — were genetically closest to wild forms from west Africa and northeast Africa, said Professor Susanne Renner. A researcher in the Institute of Systematic Botany and Mycology at the University of Munich and Washington University.

Professor Renner and colleagues found that a Sudanese form with non-bitter whitish pulp. The Kordofan melon, is the closest relative of domesticated watermelons. The results are consistent with the newly-interpreted Egyptian tomb paintings that suggest the watermelon may have been consumed in the Nile Valley as a dessert about 4,200 years ago.

“It was the Egyptian tomb paintings that convinced me that the Egyptians were eating cold watermelon pulp,” Professor Renner said. Otherwise, why place those huge fruits on flat trays next to grapes and other sweet fruits? Kamara’s Papyrus represents a citrus fruit (red circle), which is interpreted as a wild watermelon; The globose striped fruit recalls the morphology of the cordophone melon.

Other sweet fruits

The study also corrects an old taxonomic error that placed the melon in the same category as Citrullus amarus, also known as the South African citron melon. “Today’s watermelon comes from a very small genetic pool and is susceptible to diseases and pests, including various fungi, other fungi, viruses and nematodes,” said Professor Rainer.

Department of Animal

So far, we’ve found variations in three disease-resistant genes between cordophan melon and domesticated watermelon. Breeders can use these and other genome insights. Watermelon is one of the most important tropical fruits, it produces more than 200 million tons each year, but it is also susceptible to diseases, said Dr., a researcher at the University’s Department of Animal and Plant Sciences. Guillaume Chomiki said from Sheffield.

Fungicides & pesticides

“Watermelons have specific diseases, such as the watermelon mosaic virus, and they are also very sensitive to fungal infections. In traditional agriculture, they are often treated with fungicides and pesticides to limit virus transfer.” Our analysis clearly shows that the chordophan melon contains more disease-resistant genes, and also different versions of them.

This means that the cordophan melon genome has the potential to help us produce disease-resistant watermelons and enable non-GMO gene editing. Achieving this will substantially reduce the use of pesticides in watermelon cultivation. The findings were published in the Proceedings of the National Academy of Sciences.

What are the health benefits of watermelon?

Watermelon is a low calorie sweet and refreshing summer snack. It provides hydration and also provides essential nutrients such as vitamins, minerals and antioxidants.

  • Nutrition
  • Diet
  • risk

Along with melons, honeydew, and cucumber, watermelons are members of the cucurbit family. There are five common types of watermelon: seedless, seedless, small, yellow, and orange. In this article, learn more about the potential health benefits and nutritional content of watermelon, some tips for serving it, and who should limit it.



The water content in watermelon can help a person stay hydrated. Watermelon is about 90% water, which makes it useful for staying hydrated in the summer. It can satisfy even a sweet tooth with its natural sugars. Watermelon also contains antioxidants.

These substances can help remove free radicals, or molecules known as reactive species, from the body. The body produces free radicals during natural processes such as metabolism. They can also develop through smoking, air pollution, stress, and other environmental pressures. If too many free radicals remain in the body, oxidative stress can occur.

This can lead to cell damage and many diseases such as cancer and heart disease. The body can naturally eliminate some free radicals, but antioxidants in the diet support this process. Here are some of the ways that the antioxidants and other nutrients in watermelon can help protect a person’s health. What other foods provide antioxidants? Click here to find out.

Asthma prevention

Some experts believe that free radicals contribute to the development of asthma. The presence of certain antioxidants, including vitamin C, in the lungs can reduce the risk of developing asthma. Studies have not confirmed that taking vitamin C supplements can help prevent asthma, but a diet rich in vitamin C may offer some protection.

One cup of watermelon rinds, which weighs about 154 grams (g), provides 12.5 milligrams (mg) of vitamin C, or between 14% and 16% of a person’s daily needs.

Blood pressure

In a 2012 study, researchers found that watermelon extract lowered blood pressure in and around the ankles in middle-aged people with obesity and early hypertension. The authors suggested that L-citrulline and L-arginine, two antioxidants in watermelon, may improve arterial function.

Lycopene, another antioxidant in watermelon, can help protect against heart disease. A 2017 review suggested that you can do this by reducing inflammation associated with high-density lipoproteins (HDL) or “good” cholesterol.

Phytosterols are plant compounds that can help control low-density lipoproteins (LDL) or “bad” cholesterol. Some guidelines recommend consuming 2 grams (g) of phytosterols per day. 154 grams of watermelon rinds provide a small amount of 3.08 milligrams.

Lowering LDL cholesterol can help prevent high blood pressure and heart disease (CVD), but the exact effect of phytosterols on CVD is unclear.

What Foods Can Help Lower Blood Pressure?


The National Cancer Institute (NCI) notes that free radicals may play a role in the development of some types of cancer. The oxidative stress caused by them can cause damage to DNA cells.

The dietary antioxidants in watermelon, such as vitamin C, can help prevent cancer by fighting free radicals. Some studies have also linked lycopene intake with a lower risk of prostate cancer. Click here to learn more about the relationship between cancer and diet.

Digestion and regularity

Watermelon is high in water content and also provides some fiber. These nutrients help promote a healthy gut by preventing constipation and promoting regular bowel movements.



Watermelon is about 90% water and also provides electrolytes like potassium. It is a healthy option for breakfast during the hot summer months. People can eat watermelon fresh, in juice form, or sliced frozen for a delicious cold popsicle-style snack. Water is essential for health. Learn more about why we need it here.

Brain and nervous system

Choline is another antioxidant found in watermelon. It contributes to the following functions and activities:

  • muscle movement
  • Learning and Memory
  • maintain cell membrane structure
  • transmission of nerve nirbula
  • early brain development

One theory suggests that choline may help slow the progression of dementia in Alzheimer’s disease, but there is not enough evidence to confirm this.

Muscle pain

Watermelon and watermelon juice can reduce muscle pain and improve recovery time after exercise in athletes. In a 2017 study, athletes drank half a liter of a placebo or watermelon juice with added L-citrulline 2 hours before a half marathon run.

Those who consumed the watermelon drink reported less muscle soreness 24-72 hours after the race. It is not clear whether consuming watermelon juice without L-citrulline will have the same effect. People with fibromyalgia experience chronic pain. How can diet help?


Watermelon contains vitamin C, which the body needs for collagen production. Collagen is essential for cell structure and immune function. Vitamin C also promotes wound healing. Studies show that vitamin C can help promote healthy skin, including reducing the risk of age-related damage. Find out some tips on other skin-friendly foods.

Metabolic syndrome

In 2019, researchers published findings indicating that watermelon may improve characteristics of metabolic syndrome, including obesity and cardiovascular measures. In the study, 33 overweight or obese people ate 2 cups of watermelon or low-fat cookies every day for 4 weeks. Those who ate the watermelon reported feeling less hungry and satisfied for longer than those who ate the cookies. Also, after 4 weeks, those who ate watermelon:

  • high levels of antioxidants in the blood
  • low body weight and body mass index (BMI)
  • low systolic blood pressure
  • Improve waist-to-hip ratio

Those who ate the cookies had higher levels of oxidative stress than the watermelon group. His blood pressure and body fat also increased. The results suggest that watermelon may be a good breakfast option for people with obesity and metabolic syndrome.

Diuretic properties

Some people use diuretic medications to help remove excess water and salt from their bodies. It can be helpful for people with kidney problems, high blood pressure, and other conditions. A 2014 mouse study concluded that the diuretic action of watermelon may be as effective as that of furosemide, a well-known diuretic. This can make it a natural option for people with excess fluids. Never stop taking a prescribed diuretic without first talking to your healthcare provider.


The following table shows the amount of each nutrient in a cup of watermelon rinds that weighs approximately 154 grams. It also shows how much of each nutrient an adult needs, according to the 2015-2020 Dietary Guidelines for Americans. The requirements vary according to the sex and age of the person.

Watermelon also contains some:

  • – B vitamins, such as thiamine, niacin and riboflavin
  • – Zinc, manganese, selenium, fluorine and other essential minerals
  • – Tryptophan, Leucine, Lysine, Arginine and other antioxidants


When buying a watermelon, people should look for a watermelon that is firm, heavy, and symmetrical with no soft spots or bruises. Tapping on the outside can reveal the texture of the fruit on the inside. Listen to a light, almost hollow sound. This indicates that the contained water and fruit are intact and have a stable structure.

  • Tips for serving
  • Tips for serving watermelon include

Juice: Put sliced watermelon and some ice cubes in a blender for a cool, refreshing electrolyte drink that’s perfect for post-workout rehydration or a day in the sun.

Salad: Add fresh watermelon, mint, and mozzarella to a bed of spinach leaves for a delicious and healthy salad. Drizzle with balsamic dressing.

Smoothies: Make a watermelon smoothie or mix it with orange juice for extra flavor. Remember that juice breaks down fiber, making it easier for sugar to be absorbed. People with diabetes should consider eating fresh whole watermelon instead of drinking juice.

Roasted Seeds: Roast the watermelon seeds in the oven for 15 to 20 minutes to make a delicious snack. One ounce (28.5 grams) of seeds can provide about 8 grams of protein, or 14-17% from a reliable source of a person’s daily protein needs.

People should check the packaging of pre-made juices and candies as they may have added sugar and may not be healthy. Eating whole watermelon is the healthiest option. Another popular type of cantaloupe is cantaloupe. Get more insights.


Moderate amounts of watermelon pose no serious health risk to most people, but some may need to be cared for.

Diabetes: Watermelon is a fruit with natural sugar content. People with diabetes should include these carbohydrates in their daily meal plan. It is better to consume whole watermelon instead of juice, since its juice removes fiber, which makes it easier for the body to absorb sugar. This can increase the risk of a glucose spike. Remember to watch your portion sizes with all fruits and juices.
