Square Shaped Fruits: How To Grow A Square Watermelon With Kids

If you’re into weird fruits or just something a little different, then consider growing yourself some square watermelons. This is the perfect activity for kids and a great way to have fun in your garden this year. It’s easy to grow other square shaped fruits and vegetables too. All you need are some square molds or containers.

Why is a Watermelon Grown Square?

So where did the idea come from and why on earth would anyone think of a watermelon grown square? The idea of growing square watermelons began in Japan. Japanese farmers needed to find a way to work out the issue of traditionally round watermelons being too awkward by rolling around or taking up too much space in the refrigerator. After playing around with different ideas, they finally came up with one that worked—a watermelon grown square!

So how did they get the square shaped fruits to grow this way? Simple. The square watermelons are grown in glass boxes, which encourage the cubed shape. To solve the issue of having them too big, growers remove the fruit from the

container once it reaches about 19 square centimeters. Then they simply package and ship them off for sale. Unfortunately, these unique square shape fruits can be a bit pricey at about $82 USD.

No worries though, with just a basic square mold or container, you can grow your own square watermelon.

How to Grow a Square Watermelon

With the use of square-shaped molds or square containers, you can easily learn how to make a square watermelon. Alternatively, you can use this same concept to grow many other fruits and vegetables, including:

  • tomatoes
  • squash
  • cucumbers
  • pumpkins

If you cannot find a suitable square container, you create a mold using concrete blocks, wooden molds or boxes. Build a cube or square box that will be strong enough to allow your watermelon to grow, but make sure the mold or container is slightly smaller than the volume of the fruit’s average mature size.

To begin growing your square fruit, choose a type suitable to your area. Start your watermelon seeds outdoors 2-3 weeks after the last frost. Seeds should be planted about an inch deep in well-draining soil, using about 2-3 seeds per hole. Then grow the watermelon plants as normal, giving them plenty of sun and water.

Caring for a Square Watermelon

Watermelons love water and sandy loam soil, so caring for a square watermelon will be much the same as for regular watermelon plants. Once your watermelons begin to develop on the vine and while the fruit is still small, you can gently place it into the square form or container.

Watermelons have a long growing season, so you’ll need to be patient. Don’t expect to find a square watermelon overnight! As the fruit grows, it will eventually take on the shape of the square form. Once mature, simply remove the form or carefully lift the fruit from the container.

A watermelon grown square is a great way to get your children interested in helping out in the garden and will be a tasty summer treat for them to enjoy as well.

Gifting Culture is an Opportunity for Odd Shaped Watermelons:

The cultural idea is that they gift items that are much nicer and superior than what they would buy for themselves in Japan. The Japanese tradition of gifting fruit is still alive and has huge business potential in novel gifting concepts.

Gift giving melon is grown very differently from ordinary melon and the Japanese claim it has a superior scent and texture. Less than one percent of these melons which are grown only in a certain region are certified as gifting eligible differently shaped classical watermelons.

Not just anyone will receive these princess watermelons. The exclusive gift for friends, family or a boss will be appreciated and honored with the pleasure of eating these melons. These square watermelons in Japan are treated as very novel and luxury item and they use to gift during the functions and festivals.

Growing Demand for Odd Shaped Watermelons:

Let’s get one thing out of the way right up front: It doesn’t matter what shape the watermelon is, it’s what’s inside that matters. That said to admit there’s something cool about watermelons that defy convention by assuming different shapes.

Japanese farmers are growing different oddly watermelons like square, cube and heart-shaped which are paying them high. These unusual shaped sweet hearts, cubes and square watermelons started growing in Japan almost two decades ago. But how are they grown and why bother in tampering Mother Nature?

How are they Priced so High?

Japan the farmers produce square watermelons because they’re much easier to stack and convenient to store them in their little sized refrigerators. Today they are priced at high because they treat them as novel and premium for gifting.

They look decent and fit well in to gift boxes or refrigerators and it’s stable to grasp while we cut in to slices. In fact, we can stack the melons on top of one another to save more space.

The square shaped watermelons produced using polycarbonate square shaped mold or plastic case. These odd shaped are fetching 4-5 times more price than the regular watermelons because they often considered more of a fashion and sold nearly $100 bucks each in Japan.

The only thing is that square watermelons are quite expensive than the normal watermelons. In Japan, they cost 10,000 yen or about $75 – $100. The normal watermelon price in Japan ranges from $15 – $20.

There’s a report that wealthy people in Russia are paying over US $800 for Japanese square watermelons. In Russia, that’s supposedly 300 times the price of a regular watermelon. But why square watermelons? That’s so passé!

The Price Variants:

The iconic square watermelon is not a regular sight at most of Japanese super markets. It is usually priced ranging between $100 – $125. The heart-shaped watermelon first started getting attention in 2009. There are now mini versions too which are priced at around $200. Large heart-shaped watermelons can be around $350.

As far as shapes go, this might be closest to the traditional round watermelons we find in Japan. It’s called a “dynamite watermelon” and is packaged to look like a bomb. Its slogan is “An explosion of delicious taste!” It is priced at around $70 or so, making it one of the more inexpensive watermelons.

The Pyramid shaped watermelons are priced around $500 and they are available in the Japan markets since 2004.

Next to the square and other shaped melons there is a “human face watermelon”. The Japanese media discovered this watermelon in 2011 and it is priced at ¥50,000 and up, with some of the larger melons costing over a thousand bucks! The watermelon is grown into a special clip-like model, which gives it the human-like face. The price isn’t the only scary thing about this melon.

These melons are good examples of how preoccupied Japanese can be with not only food presentation, but imbuing that presentation with a sense of playfulness.

Japan Welcomes Summer with Odd Shaped Watermelons:

Japanese consumers are used to paying through the nose for fruit, and now the summer’s here there’s another way for them to empty their wallets: cube and heart-shaped watermelons.

But this pricey produce is not intended to tempt the taste buds – it’s more ornament than the perfect picnic food. Over at the Shibuya Nishimura luxury fruit shop in downtown Tokyo, a cube-shaped watermelon, about the size of a baby’s head, sells for 12,960 yen ($105). Now assume the price of a heart or pyramid shaped melons.

Japan’s Square Watermelons Gain Popularity:

Japan has a great culture known for thinking outside the box. As all we know that the watermelons are round or oval shaped. But recent times the farmers in Japan are changing it up. They are growing Watermelons in different odd shapes like heart, cube and square shaped.

The square shaped watermelons are created by placing them in a square molded box and letting them grow into that shape.

Farmers first started creating the square watermelons 30 years ago, and they are gaining in popularity. Orders for them are reportedly coming from around the world.

People Paying More:

People are paying thousands of pounds for square and heart shaped watermelons in Japan. But Japan’s designer watermelons costing £20,000 apiece are a world away from our run-of-the-mill garden variety watermelon.

Japan is most famous for its oddly shaped fruits and has designed square and heart-shaped watermelons. Fruit is big business in Japan and growers spend years cultivating extra-large and oddly shaped fruits to sell to high net-worth clients.

It’s very hard in getting the shape of these oddly shaped watermelons and consume years of time to get perfect result. ‘Especially in Japanese society ‘Fruit is considered a luxury item and plays an important and elaborate ritual part in Japan’s extensive gift-giving practices.

Can You Put a Price on Love and Care?

Something out of this world is usually priceless. Its value surpasses the baseness of money. Love and care are things which come from the heart. Nurturing nature is a full-time job and requires much self-sacrifice. Reaching perfection is the ultimate goal that will bring a great sense of personal self-satisfaction.

The marvelous differently shaped watermelons carefully grown for 125 days go through the seasons under intense protection. These baby creepers constantly monitored and diverted them to one fruit bearing and all the care is to provide with all the nutrients it needs.

Can’t you pay more for the rarely available square shaped princess watermelons which are considered novel and luxury in Japan to exclusive gift friends, family or a boss.


The differently shaped watermelons are paying 4-5 times more to the farmers in Japan. When it is possible in Japan why not in India? Our farmers have to adapt this simple technology and produce different odd shaped watermelons such as square, cylindrical, rectangle, cube, heart, skull etc. as produced by the Japanese farmers. This is an opportunity for Indian progressive farmers. Let’s grab it.

Let’s get one thing out of the way right up front: It doesn’t matter what shape the watermelon is, it’s what’s inside that matters. That said, you have to admit there’s something cool about watermelons that defy convention by assuming different shapes.

Last month, I talked about Japanese farmers who had figured out a way to grow heart-shaped watermelons. Of course, the precursor to those sweethearts are the unusual square watermelons that got their start in Japan almost a decade ago. But how are they grown, and why bother tampering with Mother Nature? Both are good questions. I’m glad I asked them.

First, the how. It’s actually pretty easy (relatively speaking) to grow a square watermelon. Just about anyone can do it. While the watermelon is still small on the vine, a square, tempered glass box is placed around it. When the watermelon gets bigger, it assumes the shape of the box! You can do this too. There are even websites dedicated to teaching you how. Just remember to use a glass or transparent mold so the sunlight can reach the watermelon on all sides (except the bottom, I guess).

And why are square watermelons grown? Two reasons actually. First, the square watermelons are easier to stack, which makes them easier to ship. Second, and perhaps most ingeniously, with space being an issue in crowded areas of Japan, the square watermelon is designed to fit perfectly inside smaller Japanese refrigerators.

But, just like the heart-shaped creations, square watermelons cost a bit more than one shaped by Mother Nature. It’s a small price to pay for the ability to store it in your fridge, although I guess you could just cut up a normal watermelon and make it fit. Oh well… the square ones still look pretty darn cool.

How Square Watermelons Get Their Shape, and Other G.M.O. Misconceptions – The New York Times

Earlier this week I wrote about organic food and whether it is really healthier. To be sure, organic food can be a healthy alternative to conventional food, but many times the difference may not be as great as commonly believed. In some cases, organics simply may not be the smartest choice.

One reason why people choose organically produced foods is that they don’t contain GMOs, or genetically-modified organisms. Many people believe that GMOs are dangerous or, at the very least, make foods less healthy.

Unfortunately, just like with organic food, there is a great deal of confusion about GMOs in food. An article in the New York Times addresses some of the misconceptions about GMOs.
In an effort to inform consumers about the presence of GMOs in their food, the U.S. Senate recently passed GMO-labeling legislation that has received much criticism. No doubt this is something we will hear more about in the future.

Nutrition, exercise, and health information can be confusing. But it doesn’t have to be that way. What can I help you with? [email protected] |

A spoof “Bonsai Kitten” web site sparked a good deal of outrage, but pictures of “bonsai watermelons” have prompted only wonder and amusement:

Square Watermelons

A round watermelon can take up a lot of room in a refrigerator and the usually round fruit often sits awkwardly on refrigerator shelves.

Smart Japanese Farmers have forced their watermelons to grow into a square shape by inserting the melons into square, tempered glass cases while the fruit is still growing on the vine.

These photographs were used to accompany news articles about the unusual square watermelons back in June 2001. Most of those article explained that the oddly-shaped fruits were developed in Japan in order to take up less room in refrigerators and were created by inserting still-growing melons into glass cases:

Farmers in the southern Japanese town of Zentsuji have figured out how to grow their watermelons so they turn out square.

It’s not a fad. The technique actually has practical applications. “The reason they’re doing this in Japan is because of lack of space,” said Samantha Winters of the National Watermelon Promotion Board in Orlando, Florida.

A fat, round watermelon can take up a lot of room in a refrigerator, and the usually round fruit often sits awkwardly on refrigerator shelves.

But clever Japanese farmers have solved this dilemma by forcing their watermelons to grow into a square shape. Farmers insert the melons into square, tempered glass cases while the fruit is still growing on the vine.

The square boxes are the exact dimensions of Japanese refrigerators, allowing full-grown watermelons to fit conveniently and precisely onto refrigerator shelves.

But cubic fruit comes with a caveat: Each square watermelon costs 10,000 yen, the equivalent of about $82. Regular watermelons in Japan cost from $15 to $25 each. Since 1994

Have you ever wondered if Japanese square watermelon tastes good? What about heart shaped watermelon? Are Japanese watermelons edible?
According to a new report from, the fruits are not tasty. Watermelon has many known health benefits, but when you mess with mother nature to make a cubed or heart shaped watermelon you lost taste.

“…by the time it is the proper shape, it has not been given the time needed to also mature. As such, one can buy a non-edible square watermelon for nearly $100 from posh upscale supermarkets and use it as decoration or gifts that could last up to a year or more.” In Najarian’s opinion that makes square watermelons pretty useless, despite the fact that they’re produced to make them easier to store..

The watermelons, which are grown in square plastic containers that force them into square shapes, are harvested when they are unripe, and are largely inedible.

Hannes Joubert, one of the largest watermelon producers in South Africa, and director of Habata in the Eastern Cape, said that Japan’s market for cube- shaped watermelons was very small.

He added that the primary reason for the development of the square shape was to enable the watermelon to fit inside a fridge.

“ is a very limited market. The costs involved are immense because every watermelon needs to be placed inside a box, which is labour-intensive,” he said.

Joubert, who produces approximately 10 000t of watermelons a year, added that it was impractical to produce square-shaped watermelons. According to him, it was a purely cosmetic trend, and Japanese consumers often bought the square watermelons as gifts.

“The South African market is interested in affordable, practical and edible watermelons, such as seedless watermelons,” he explained.
There are currently six cube-shaped watermelon growers in Japan.
