The Science Behind Making Square Watermelons: A Detailed Guide and Its Popularity in Japan

Watermelons are typically known for their round shape, but in recent years, a unique variety of square watermelons has captured the attention of both growers and consumers around the world. This article explores the process of making square watermelons, their origins in Japan, and why they continue to be a popular novelty item.

Introduction to Square Watermelons

Square watermelons are created through a process of controlled growth, typically using specially designed molds. Unlike their round counterparts, these watermelons are not necessarily more flavorful or nutritious, but they are highly sought after for their novelty and aesthetic appeal. This guide will explain the steps involved in creating square watermelons, focusing on their unique shaping process.

Mold Creation

The first step in creating square watermelons is to craft a rigid mold capable of withstanding the pressure of the growing fruit. The mold should be made from a material that is robust enough to maintain its shape throughout the growth process. Common materials include plastic, metal, or even glass. The mold must be slightly smaller than the desired final size of the watermelon to allow for its natural growth and expansion.

Planting and Development

Once the mold is ready, a watermelon seed is planted in the ground. As the melon begins to grow, it is carefully placed into the mold. The mold will restrict the melon from growing naturally, forcing it to take on a square shape as it develops. To ensure optimal growth, the plant is cared for just as any other vine. This includes regular watering, fertilizing, and pollination management.

Harvesting

Once the watermelon has matured, usually after several weeks, it is carefully harvested while still inside the mold. The mold is then removed, revealing the square watermelon. In the case of glass molds, the mold must be carefully broken away, while plastic molds can be cut off to minimize damage to the fruit. This process can be intricate and requires a gentle touch to maintain the fruit's perfect shape.

Popularity and Usage

While square watermelons were initially created for novelty and decorative purposes, they have gained popularity in Japan as unique gifts or home decor items. Japanese farmers discovered that by placing a glass-tempered box around young watermelons, they could encourage them to grow into the shape of a cube. This method involves using transparent containers to allow sunlight to reach the fruit while shaping it.

These cubic watermelons, while ornamental, are not meant for consumption. They are primarily produced as a whimsical display item, appealing to those who appreciate unique and artistic design in their home or as gifts for special occasions. The process of growing a square watermelon can be fascinating and serves as an excellent conversation starter at events and gatherings.

Conclusion

The creation of square watermelons showcases the innovative practices in agriculture and the art of shaping fruits. While they may not offer any functional or nutritional advantages over their round cousins, square watermelons have become a symbol of creativity and uniqueness. Understanding the process behind their formation can inspire both growers and consumers to appreciate the artistry and science that goes into making these delightful, square watermelons.
