Best 10 Watermelon Varieties Seeds to Grow

Who doesn’t love a large and delicious watermelon during the summer months? Watermelon is a delicious fruit with a rich history. This fruit grows from vines, and there are thousands of varieties all around the world! Even if you only have a small space to grow, such as an apartment or container, you can still grow watermelons if you buy the right variety of seeds!

What are Watermelons

Watermelons are a part of the Cucurbitaceae family, with large leaves and even longer vines. Like many other fruits, watermelon plants start as a seed. With time they grow and produce bright yellow flowers. However, the color of the flower depends on the exact variety. Through pollination, the flower dries out, and the watermelon grows from the flower.

These plants are delicious and easy to grow! They are especially popular in the United States and China. ⅔ of the watermelons sold in the world came from China. Watermelon plants are also very unique! The Viney plant produces a male and female flower. Although the wind does help with pollination, you can self pollinate your plants using a thin brush.

Watermelons can be planted both vertically and horizontally. If you are growing watermelons from seeds in a raised bed, they do well on the ground. The vines stretch, and the large leaves protect the fruit from critters, bugs, and harsh weather. For those of us with small spaces, sadly, growing horizontally or in the ground is not an option. Thankfully, there are watermelon varieties made especially to climb up a trellis or stake.

What color watermelon is the sweetest? Typically, Watermelons have a green, yellow, and brown pattern on the outside, that protects the fruit and seeds on the inside. The hard ‘shell’ is similar to a pumpkin’s outsides.

The fruit on the inside is edible and is usually a bright red with little black seeds throughout the plant. While this is the case, not all watermelons are bred the same! There are yellow, pink, and white varieties of watermelon that taste different and yet are still delicious. Usually the redder the inside, the sweeter the watermelon.

Why are watermelons striped? The beautiful and eye-catching stripes on common watermelons is an indicator of readiness. However, the number of stripes doesn’t matter. The only thing we need to focus on is the color between the stripes. The lighter it is, the riper it is.

The History of Watermelons

So, what about the history of watermelons? The history of watermelons is actually a long story! This delicious and vibrant-looking plant has been around for over 5,000 years. The first account of a human planting or eating Watermelon dates back to southern Africa thousands of years ago. Archeologists in this area discovered paintings recently that depict a gourd that appears strikingly similar to what we know as a watermelon today.

Sadly, the Watermelon’s ancestor is now extinct, but experts believe this was the first depiction of it. Not even 1000 years later, and suddenly there were Watermelons painted in the walls and tombs of pharaohs in Egypt. The first purpose of Watermelon was for hydration. About 90% of each Watermelon is mainly made of water. It is said that the first Watermelon most likely did not have much flavor. Instead, ancient Egyptians bred the original Watermelon with other varieties to give it some sweetness.

No longer was the purpose of a watermelon to dehydrate, but as a treat enjoyed by all. Each part of the world had its own version of a Watermelon with its own separate purpose. For example, in Greece and Rome, doctors and philosophers used Watermelon to heal and hydrate others. Even in the bible there is a mention of this delicious fruit.

As ships began to travel more efficiently between the warm places in North America and the Caribbean, the Watermelon plant spread! Not only was this a fruit you could buy in a market now, but it also grows in your own garden as long as you have enough sunlight. By the 17th century, you could see Watermelon plants throughout Europe.

Watermelons are even grown in Japan! What’s the most expensive watermelon? The cube watermelon, which is popular in Japan and can sell for over thousands of dollars. It is more expensive the sweeter the variety.

The history of Watermelon does not stop there, though! Horticulturists now breed different varieties of Watermelon together to get varieties like the seedless Watermelons and the Miniature Watermelons.

The Benefits of Eating Watermelons

With how sweet and sugary the plant is, it is surprising just how many health benefits come from eating watermelons! The various benefits include: strengthening heart health, aiding in weight loss, and hydration!

Strengthening Heart Health

Did you know that eating Watermelons can help strengthen your heart health? Watermelons contain lycopene, which can be used to lower cholesterol. This strengthens your heart’s health, as it decreases the chances of getting a heart attack.

Aiding in Weight Loss

For my fellow snackers out there that enjoy eating, watermelon is a delicious dessert that is low in calories! This means you don’t have to worry as much about eating ‘too’ much or going over your calories. The average calories per serving for Watermelons is just 46 calories.

You can get creative when trying to lose weight and eating fruit. For example, watermelon is a tasty snack and dessert, and it compliments salads very well!

Hydration

Watermelons are best known for their hydrating properties! The number one benefit of watermelon varieiteis is that they provide delicious fruit and hydrating fruit. The sweet taste makes me forget I am eating a plant made of almost entirely water.

There is nothing better than taking a bite out of a juicy watermelon slice on a hot summer day. For children that struggle with drinking enough water or fluids, you can always give them watermelon, since it is over 70% water.

Vitamins and Minerals

There are many vitamins and minerals in Watermelon that can give you your daily intake easily! The serving size depends on the variety, however, most melon varieties contain:

  • Vitamin A
  • Vitamin C
  • Vitamin D
  • Potassium
  • Magnesium


How Long Do Watermelons Take to Grow

Watermelons are very tricky plants, but they grow very large once they are established! Watermelons all differ, which means that the growing time also is different! For example, sugar baby watermelons, which are smaller than average melons great for growing in containers, take less than 100 days from planting the seed to produce fruit and an abundance of flowers.

Tips on Growing Delicious Watermelons from Seeds

Truthfully, watermelons are not hard to grow! The hardest thing about watermelon plants is getting the flowers to pollinate and produce fruit. Once the fruit is producing, there is an even harder thing to tackle though: the weight of the watermelon.

Vertical Growing

Contrary to popular belief, you can grow watermelons virtually anywhere! While it is common to see watermelons in large plots of land and in big gardens, you can creatively choose watermelon varieties that grow vertically to save space.

If you choose to grow vertical watermelons, you do need to watch out for the weight of the plant! Since watermelons can grow to an impressive size of 70lbs depending on the variety, you need to create a net or tie the vines and fruit to a stable platform. The best way to do this is to use a tomato stand to tie the vines and fruit with light rope.

As the watermelon grows larger, simply take a look at it and make adjustments as needed. Some people use arches and encourage their Watermelon varieties to vine through the holes. This gives more support, stability, and your garden a beautiful and elegant look!

Container Growing

Did you know that you can grow some watermelon varieties in containers? It’s surprisingly easy and quick to do! Since watermelon plants are susceptible to damage and trauma from pests and bugs, bringing your plants inside can lessen the impact.

If you do choose to grow Watermelon plants in a container, the container has to be large enough to accommodate the watermelon plant. You should use a container that is a minimum of 5 gallons! The soil should be well draining and the container needs to have holes at the bottom. Watermelons do not like moist areas and can develop root rot if left in too much water.

The best variety to grow in small spaces like containers is the Sugar Baby Watermelon. You can have approximately three plants in a 5 gallon container, if they are spaced out correctly. If you are choosing to grow Sugar Baby watermelons inside, then you need to grow them by a window, in a well ventilated area.

Growing plants inside is fun, but can attract pests, diseases, and form mold if there isn’t ventilation. You can invest in a fan for your Sugar Baby watermelon plant and grow lights so that it gets sufficient lighting. Since it is artificial lighting, you may need to add extra nutrients to the soil so your watermelons grow and thrive!

In containers, you also have to self pollinate your plants. This means that you need to take a small brush and find the female and male watermelon flowers. You are going to brush or ‘tickle’ the inside of each flower and pollinate the female flower.

Fertilizer

Using fertilizer on watermelon varieties is tricky! Since there are thousands of varieties and they all require different things, it is impossible to pinpoint one fertilizer or method of fertilization that works for all plants.

The most common fertilizer for watermelon though is a liquid fertilizer made with extra nitrogen. Like beans, watermelon varieties need nitrogen to produce the vibrant green in their leaves and outer shell. You should only use fertilizer if it is absolutely necessary though. If you accidentally use too much, you can stress out your plant and kill it.

While it is tempting to use fertilizer to get the best results, not all plants need any extra nutrients! Unless you take a sol test and your plant is low on nitrogen, you shouldn’t add any more. Fertilizer should only be used in cases where your plant is missing important nutrients to grow and thrive.


Conclusion

All in all, watermelon varieties are a delight to have in any home garden. The fruit produced by the plant is delicious, hydrating, refreshing, and used as a medicine in other cultures. Watermelon does not have to be incredibly hard to grow! While some of us may not have a lot of space, there are options which include containers and vertical growing.

However, before deciding to grow watermelon, it’s important we learn about the plant and the many varieties there are! For thousands of years, humans have been modifying and breeding watermelon varieties to create hybrids that are heat friendly and pest resistant. There are even varieties that grow small watermelons weighing less than 10lbs.

Regardless of which watermelon variety you choose to grow, it will be rewarding to watch the flowers start producing juicy and scrumptious fruits!
