How Long Does Watermelon Last? (Tips To Store For Long Time)

Watermelon is about 92% water, while the remaining 8% is rich in vitamins, antioxidants, lycopene and amino acids, making it a superfood.

Unfortunately, it won’t last forever, and you should determine if the watermelon is perishable and how long it lasts before deciding to eat it. Let’s see.

Does watermelon go bad?

Like other foods, watermelon can spoil quickly. Packages of pre-cut watermelon always have an expiration date on the label, and you should take it seriously. The problem is that a bad watermelon is regularly seen and smelled, but its sour taste indicates that it is no longer edible.

Remember that this fruit will improve its quality if you keep it whole and cut it before eating. The rule of thumb is to keep it at a lower temperature if you plan to store it for a long time.

How long does watermelon last?

Watermelon, like any other fruit, will not last long, and you can keep the whole fruit at room temperature for about a week or 10 days, in some cases, without fear. If you refrigerate it, it can last up to three weeks.

Unfortunately, once you cut your watermelon, you need to eat it within a day or refrigerate it for 3 to 5 days, from the time of purchase to its initial freshness. First it depends on the storage method and additional handling. . The only option for long-term storage of watermelon is to freeze it.
Once you cut the watermelon into slices, always wrap the leftovers properly and refrigerate. Store small pieces in a resealable bag or airtight container or wrap the fruit tightly with plastic or aluminum wrap. That way, you can enjoy your treat for more than a day.

If you decide to buy tightly wrapped quarters at the supermarket, they will be covered with plastic wrap. If you can’t eat a whole piece at once, you should store the fruit that way. Cut as needed and re-wrap before storing the rest in the fridge or freezer.

4 Tips to Tell if a Watermelon Has Spoiled

Expiration date

Always follow the shelf life of watermelons strictly to avoid unpleasant surprises. This is especially important when you buy pre-cut fruit.

Nitrate presence

One of the best ways to know if your watermelon is fresh and has ripened naturally is to test for the presence of nitrates. Avoid watermelons with yellow skin and white stripes.

A proven method is to mash a piece of pulp and add it to a glass of water. If you have healthy fruit, the water will be cloudy. However, watermelon with a very high percentage of nitrates will give the water a red color. It is better to avoid it.

Physical appearance

  • Color – A shade of pine green with or without stripes depending on the type of watermelon. Any deviation from the normal color should be suspicious to you.
    Mold – Any dark spots or white, dull, green or black mold on the rind of the watermelon indicates that your fruit has gone bad.

Within the appearance

  • Texture – Dried, mushy, dry, mushy, or thin flesh is a clear sign that you have a bad watermelon.
  • Color – deep pink or clear red indicates that the fruit is healthy. To avoid food poisoning, if the color is yellow, orange or black, never eat it. Note that some varieties such as Tender gold, Yellow Doll, Desert King, and Yellow Baby have naturally yellow or orange flesh.
  • Odor – A musty or vinegar-like smell is a sign that the watermelon has gone sour.
  • Taste – A sour taste instead of fresh, sweet and juicy will tell you that the watermelon is spoiled, so you should not eat it.
  •  Hollow core – This indicates that the watermelon is overripe or contains growth hormones, which can cause poisoning.

6 Tips for Storing Watermelons

As I mentioned earlier, the best way to store watermelon is to keep it whole and cut it before eating. However, you can also store it for a while with a few simple methods. Let’s look at your options.


Since sliced ​​watermelons are only edible for one day when stored at room temperature, a better option is to refrigerate the slices for a few days. Be prepared that refrigeration will change the texture of the flesh and reduce the nutritional benefits of this fruit.

Check for signs of spoilage, wash the skin to remove dirt from the meat, and make clean slices to minimize spoilage. Then, wrap the fruit tightly in plastic wrap before storing it in the refrigerator.

If you prefer to keep the watermelon chunks, you can deseed the chunks:

resealable bag
Sealable container
Airtight container
This way you will preserve the taste and freshness of the fruit.


Freezing watermelon will prolong its shelf life, so you can use small cubes to make a smooth and fresh drink even during the season. You can also make ice cubes of blended watermelon and place it in cube trays or fill popsicle molds. One option is to combine watermelon with spices, other fruits and vegetables to make delicious dishes.


Drying watermelon is an effective way to preserve it because the low water content prolongs its shelf life and prevents rotting. Use a dehydrator to dry watermelons as this is the best way to regulate temperature and air circulation during the process.

Before drying, you need to peel the skin and cut the fruit into thin slices. The procedure will last about 24 hours. If you store the pieces properly, you can use them as a spicy afternoon snack or make candy for your kids.


Pickled watermelon is very popular in Russia for a reason. You can pickle whole fruit, peel or meat in hot pickling solution depending on your preference and taste. Most recipes include ingredients like vinegar, lemon juice, spices, and sugar.

Make slices or cubes and arrange them in mason jars. Bring the ingredients to a boil and pour the hot liquid over the watermelon. Seal the jars, let them cool to room temperature, and store in the pantry.

Candied Watermelon Peels

Cut cubed peels and dip in sugar syrup. Boil them until the mixture reduces to a thick, jam-like consistency. Add cinnamon to enhance the flavor and let the mixture cool.


Making watermelon jelly is not a complicated process. Boil the fruit juice until it becomes a thick, clear mass. Don’t forget to add sweetener and pectin according to the recipe.

Danger of consuming expired watermelon

Consuming spoiled watermelon can quickly lead to food poisoning. The first signs that something is wrong will appear within a few hours and include:

Fatigue and headache
Nausea and vomiting

In some severe cases, the patient experiences high temperature, joint pain and aches. An additional problem is food poisoning due to Listeria, which can grow on the rind of the watermelon and infect the flesh after cutting.

You should also be careful if you have diabetes because this fruit is high in natural sugar. Watermelon can rarely cause an allergic reaction, followed by difficulty breathing and swelling after consumption.

Also, the role of lycopene in it and how it affects human health is not fully understood. However, it will help if you avoid watermelons with yellow fibrous pulp and shiny, polished pulp that has a sour smell.

Can you freeze watermelon?


Because it has a high water content, freezing is not the best choice for storage. Actually it is not the freezing process but the appearance of the fruit after thawing that is the problem. Once you melt it, you will get a red portion without the desired color and taste.

However, you can use watermelon to make fruit-infused water and smoothies. To get a smoothie you mash and blend it so that there is no problem with any texture change. When you decide to make a refreshing summer drink, you can use watermelon cubes in water instead of regular ice cubes.

Watermelon Cubes – To get them, you need to scoop out the seeds, cut the flesh into small cubes, and place them on a tray until frozen. Then, pack the cubes in a freezer bag and use when needed.
Fruit Infused Water – Prepare watermelon in fruit water, freeze slices in ice cube trays, and use whenever needed.
Thaw the watermelon cubes overnight in the refrigerator. If you have a smooth blender that can grind ice, you can freely use frozen cubes to get a delicious and refreshing drink.


Watermelon can spoil quickly, but noticing the signs of spoilage is not that complicated. Always check the outer appearance and flesh of a melon before buying it. Next, take care to store the fruit properly to extend its life.
