Can you eat square watermelon?

In this article, we will answer the question “Can you eat square watermelon?” and discuss how to make it?

Can you eat square watermelon?

Yes, you can eat square watermelon but it has no taste. Real square watermelons do exist, but they’re quite costly and difficult to come by. Prices in Japanese retailers may reach over $100 if they’re adorned with bows, while prices elsewhere can go as high as $860.

Special seeds aren’t needed to produce square watermelons. Regular melons were grown in boxes while being housed in the greenhouse. As a consequence, the fruit is simpler to carry, chop, and store because of its new form. 

In addition to looking good in Japanese refrigerators, square watermelons also fit in with the country’s habit of presenting pricey, attractive fruits as presents.

The square watermelon business in Japan is centered in Zentusji, Kagawa Prefecture, and several sources attribute the invention to a local farmer in the 1980s. However, Tomoyuki Ono, a Japanese gardener, and artist sought to patent a “shaping procedure for a natural fruit” in 1978. 

Using a “transparent molding frame,” Ono discovered a melon would grow to fit the enclosure, and he displayed his creation in a gallery exhibition as proof. At the time, square watermelons in Tokyo sold for roughly $20, compared to $9 for an older oval melon. This was reported by United Press International at the time of its launch.

Today’s square watermelons are more attractive to look at than they are to eat, despite the assertion in Ono’s patent that “the molded fruit’s flavor is no less than that of a natural fruit.” Before they are completely mature, they are picked and used to make ornamental presents.


To begin, I’d want to state the obvious: It doesn’t matter how the watermelon looks on the outside; what’s important is what’s inside. Having said that, you have to realise that watermelons that break convention and take on new forms are really fascinating.

Japanese farmers have developed a method for growing heart-shaped watermelons, which I discussed last month. The unique square watermelons that were developed in Japan about a decade ago are, of course, the forerunners of those sweethearts. 

The question is, how do they develop, and why mess with nature? Both of these inquiries are well-intentioned. You asked them, so I asked you.

This is the first step: determining how to proceed. To cultivate a square watermelon, you don’t need much effort. It’s simple enough for just about everyone to understand. A tempered glass enclosure is put around the watermelon while it is still young on the vine. 

Growing a watermelon changes its form into a box! This is something you are capable of doing as well. You can even learn how to do it from websites that show you how. Just keep in mind to choose a clear or glass mold so that the watermelon receives sunshine from all sides (except the bottom, I guess).

What is the purpose of growing square watermelons?

Actually, there are two reasons for this. For starters, shipping square watermelons is simpler since they can be stacked more neatly. To make better use of limited space in Japan’s densely populated regions, the square watermelon was created to fit neatly into the country’s tiny refrigerators.

However, square watermelons are more expensive than those made by Mother Nature, exactly as the latter’s heart-shaped wonders. Even so, it’s a little amount to pay for the convenience of being able to keep it in your refrigerator. Even though they’re square, they’re still fairly sharp-looking.

What different shades of green, yellow, and red can you find in watermelons?

Most people have seen the bright reddish-pink flesh with black seeds, however, there are other colors as well as those without seeds. Seedless and yellow-orange fleshed watermelons are subcategories of the other three.

Is it possible to eat watermelons that have been cut into cubes?

Toss off the idea of a square watermelon. They can’t be eaten. While eating a square watermelon is an interesting novelty, the taste is likely to leave you unimpressed. Instead, go for a heart-shaped watermelon, which is not only attractive but also delicious.

Gene-splicing in seedless watermelon: Is it possible?

When this happens, you’ll have clones that are exactly the same genetically as the original. Seedless watermelons, on the other hand, are produced from cuttings. Watermelon diploid and tetraploid lines are crossed to create these seeds, and the resultant sterile triploid plants are grown from the seeds.
