Hi, I sowed some white radish in the end of July. Now they are blooming but roots are very small. Will the roots continue to grow? and what should I do for them?

If they have very big leafy tops you are over fertilising BIG TIME. Plant radish after a leafy crop so that a lot of the N has been used. My experience is to grow radish into winter -sub tropical.

The most likely reason is that you have left them in the ground too long.
