I have in my kitchen a daikon radish of about fifty centimeters whose tops, shortened to 1 cm at the time of purchase, start to grow again even though it is no longer in the ground. They are today 8 cm long and look vigorous.

Do you think it's possible to make it go to seed before the root is completely depleted, and if so, how?

I'm considering putting it back in the ground or in a mix of sand and potting soil, after perhaps one night in the water, but maybe there is a better way.

The goal is to get seeds from this particular specimen (several species of daikon radish exist and obviously the supermaket is unable to say which it is), but also to succeed in the replanting experiment.

Note: I am in a temperate climate where there is no risk of frost until mid-December.


I would grow it in just water with nutrients, changed regularly. I suspect there is a high chance of the root going mouldy otherwise.
