My large oriental radishes always seem to bolt, the first planting only. I know its not a hardiness problem, subsequent plantings produce large crops, once the radish sends up a flower there is seldom good root formation. I've tried new seeds, old seeds, the ones planted in march april and may seem to go! Whats up with that?? |
Interestingly enough, and unlike red garden radishes, the oriental radishes are known to bolt in early cool spring planting. To get that first early sowing in, try a variety specifically developed for early planting and listed as bolt resistant such as "Spring Song". |
