I have some nice big fat daikon growing, they do really well in my yard, I am going to shred and ferment them. Is there a best time to pick them, a time when the flavor is the best? Some have shot up flowers already.
Flavor is best when they are grown in cool weather, and the younger the better. But younger equals lower harvest weight.
They get fibrous when they start flowering. I don't like to eat fibrous radishes.
So for me, the best time to harvest is after the bulb has grown to a respectable size, but before the plant starts flowering.
