The Square Watermelon!!
Invented just in time for National Watermelon Day!
I'm making that up, however, the square watermelon was invented in Japan whereby they would grow the fruit in glass boxes and allow it to assume the size of the box. Initially, the idea was to make the melons easier to stack in the truck for shipping. But, due to the growing and harvesting costs, the square melons wound up about twice the price as regular watermelons. These melons, however, proved to be very popular as novelty items, in addition to other shapes, like the pyramid melon.
If you've got the acreage, the good folks over at Instructables have come up with a step-by-step plan, including a full photo essay, on what you'll need to make your own boxes to grow your very own square watermelons, or any other shape for that matter, in the privacy of your own garden.
And, by the way, this works on just about any type of fruit too!
