Watermelon seeds are a delicious and nutritious snack for you, your family, and your friends. They are also great for planting next year’s crop of watermelons. However, if you want to store them so that they will last longer than just one season, then you need to know how to store watermelon seeds for next year.

To begin with, you should store your seeds in a dry place where they won’t get too hot or too cold. If it’s too hot or too cold, the seeds won’t grow into plants because they won’t be able to germinate properly. If this happens, then all of your hard work will be wasted.

You should also try not to let moisture get on the seeds while they’re stored away from their original source (the watermelon itself). Moisture can cause mold and mildew growth on the seeds which can prevent them from growing properly when planted in soil later on down the road when spring comes around again next year after winter has passed by again. If possible – store them in an airtight container such as Tupperware or other similar containers made out of plastic material (not metal). You can also purchase special seed savers that are specifically designed for storing seeds.

How To Store Watermelon Seeds For Next Year

The best way to store watermelon seeds is in an airtight container in a dark, cool place. They can last for up to five years if stored properly. If you are planning to grow your own fruit next year, it is a good idea to save as many seeds as you can.

In a cool, dark, and dry place

It is important to know how to store watermelon seeds for the next year. It is best to save seeds from the ripest fruit during the summer months. It is also helpful to mark fruit that will produce good seeds early in the season. This is because watermelons tend to cross-pollinate. Moreover, watermelons should be grown at least twelve miles apart, to prevent the seed from mildewing.

When it comes to seed storage, it is best to use well-sealed glass jars. You can use these jars to store the seeds in cool, dark, and dry locations. Some good options include basements, refrigerators, and heated garages. If you don’t have a garage or utility room, you can store the seeds in an old envelope or paper lunch bag.

Seeds should be stored in a dark, cool place where the temperature stays between 35-40 degrees Fahrenheit. They shouldn’t be stored at freezing temperatures, as the seeds might germinate prematurely and cause damage to your food. If you are storing seeds for a long time, you should consider purchasing a temperature-controlled unit. This way, you won’t have to worry about cold outages and temperature fluctuations.

Once you have collected your seeds, the next step is to dry them. Once dry, you can store them in an airtight container, which will ensure that they stay viable for at least five years.

In an airtight container

Watermelon seeds can last up to 5 years in an airtight container when stored in a cool, dry place. If you live in a humid climate, you can store them in an attic or basement. Keep them at a temperature between 40 and 45 degrees Fahrenheit. Keep them away from birds and rodents so they won’t spoil.

When storing watermelon seeds, make sure that you place them in an airtight container that is away from children and pets. It’s important to let the seeds dry completely before storing them, or the moisture will get inside of them. If they aren’t completely dried, they will give off a foul odor and may become unusable. To avoid this problem, be sure that the seeds are spread out over several days to allow them to completely dry.

Once the seeds are dry, you can store them in an airtight container in a cool, dark place. Once you have them, you can plant them in late spring or early summer. Remember to soak them for at least 24 hours and then dry them out. The seeds will last for up to 5 years when stored properly.

It is a good idea to store seeds in the refrigerator, but they must be kept at a slightly cooler temperature. Keep them between 35 and 40 degrees. Seeds stored at lower temperatures can become damaged by frost. So, a separate temperature-controlled location is best for seed storage, where the seeds will not be exposed to frequent cold-outs.

Using non-hybrid varieties

When it comes to storing watermelon seeds for next year, using non-hybrid varieties is the best way to preserve your fruit’s seed supply. Hybrid seeds are not good for seed saving because the pollen can be moved from one variety to another by insects. By mixing non-hybrid seeds from several plants, you can avoid this problem.

One non-hybrid variety that is good to save for next year is the ‘Crimson Sweet’. This variety is open-pollinated, produces very large fruit, and is disease resistant. It can weigh from 25 to 35 pounds at harvest and has thick, dark-red rinds. This watermelon can be started indoors and transplanted once the last spring frost has passed.

Another option for preserving watermelon seeds is air-drying. Spread out the seeds on a baking sheet or foil. Place the baking sheet or foil in an airy place, away from sunlight, and wait 36 to 48 hours. Seeds should be firm and plump.

Another option for storing watermelon seeds for next year is to use non-hybrid varieties. This option can save you a lot of money and is more efficient than using hybrid seeds. Non-hybrid varieties are more easily adaptable to a given climate. Besides, they are less expensive to produce.


When washing watermelon seeds, be sure to remove all flesh. You can do this by using a knife. Then, spread the seeds out on a paper towel. This will keep them moist and extend their life. This also improves germination rates and seed quality.

The first step is choosing the right watermelon. Select one that has plenty of nutrients. Also, choose one that has good taste. The color of the fruit also plays a role in the saving process. Moreover, keep in mind that watermelon seeds should be stored away from the market plants.

The watermelon is rich in water and nutrients. This fruit is delicious and healthy, especially when grilled. It is full of antioxidants that improve the heart and the immune system. It is also good for your skin and can help lower blood pressure. Watermelon is a popular summertime treat and can be saved for the next year.

Before storing watermelon seeds for next year, be sure to rinse them. This will remove excess sugar. This is necessary because melons are high in sugar and will kill seeds during storage. Use dish detergent to clean the seeds, but use an eco-friendly detergent if possible.

After cleaning the seeds, you can plant them in your garden the next year. Watermelon seeds are a good source of nitrogen, which will help the plant grow. You can also sprinkle them with cinnamon, sugar, or lime to add flavor. If you want, you can add cayenne pepper or chili powder.


Watermelon seeds are very susceptible to various diseases, especially in wet and humid weather. Watermelon plants can be damaged by extended periods of rain, which can cause foliar diseases, such as gummy stem blight, downy mildew, and powdery mildew, to appear. Fusarium wilt and Alternaria leaf spot are other diseases that can also damage watermelon plants. Both these diseases are largely preventable by crop rotation and the use of non-host species.

Using a row cover is an effective method for preventing pests from pesky seeds. It’s also important to keep your plants from drying out too quickly. Water the plants 1 to 2 inches per week, but don’t allow them to become waterlogged. You can increase the yields by mulching raised planting rows with black plastic film.

Using a dehydrator can help you store your watermelon seeds for next year. Before you do, remember to keep them in a dark, cool place to avoid moisture and humidity. Once dried, watermelon seeds will keep for about four years.

A general-purpose fertilizer is best used every two to four weeks but doesn’t over-fertilize. Excessive nitrogen can cause the vines to grow uncontrollably, which will lead to reduced fruit quality. It’s also important to keep in mind that watermelons are large plants, so you should allow plenty of room for them to grow.


Once watermelons have finished fruiting and seeds have fallen to the ground, it’s time to harvest and store them for next year. This process involves cleaning seeds and storing them in an air-tight container. It’s important to keep watermelon seeds in a cool, dry location, away from moisture, heat, and pests. Watermelon seeds can last for weeks or even months if properly stored.

First, clean the seeds with a knife and spread them out on a piece of paper. By doing this, you’ll extend the shelf life of your seeds and improve germination rates. This will also restore the quality of the seeds. Once you’ve saved the seeds, you can plant them next year.

The seeds of the watermelon should be stored for about four weeks. This will allow you to harvest them as early as mid-June if they’re planted early enough. The key to growing watermelons is to choose a variety with lots of nutrients. Choosing the perfect variety also depends on its taste and color.

Another way to store watermelon seeds for next year is to air-dry them. This can be done easily with a conventional oven. All you have to do is spread the seeds on a sheet of paper or foil and leave them in a cool, dry place. After a few days, the seeds should be hard and brittle and should have shrunk a little.
