why would radishes bolt without producing a radish
We planted radishes too late in spring and they bolted 4 weeks after planting. One plant produced the perfect radish, but none of the others have any radish at all. What happened?

Radish is a cool weather crop. To warm of temperatures can cause the plants to bolt.
Also to tightly planted together can cause the bulbs to not form.
