Square radishes/turnips?

Last year I got a radish seedling tape, and they grew very well. However, I did thin them out a lot. Now in 2024, I was thinking if it was possible to make square radishes, like by planting them very closely in a square, then they are kind of molded into a certain shape. What do you think?

Seems possible. The Japanese do it with watermelon but they’re bigger and easier to deal with

I guess I could use a square mold and put it underground…

once I planted turnips in a concrete block - the one with a smaller hole - and forgot about it. Turnip did grew square… until one day it crashed the block it was growing in…

They sell the mold in china. But not for radishes. It would work. Why do you want a square radish?

I guess it would just look cool.

You could market a mold and what’s nice is radishes grow so fast. A really good vegetable to introduce gardening to young kids. Growing in colored “radish boxes” would make a cool kit for beginner gardeners.

I did buy these years ago and they really worked! I had zucchini too in these shapes. They were far easier to control above ground.

That’s really cool. Did you buy the molds?

For radish you’d need to keep soil out of the mold. If there were soil in the mold, the shape would be distorted or soil/gravel might be pushed into the radish.

Good point Steve, since it’s a root it would be hard to get it to work. Open ended maybe 6 inches long. It has to be in soil it’s a root. the soil hopefully will be pushed up or down.

It would be difficult with radish because its underground, the roots probably get damaged and dirt pressed in.

I grew these in 2015:

You can buy them all on line! They are not for fruits or veggies planted under soil.
