Well, as you have probably guessed, the radishes are starting to bolt. I planted them on Apr. 24, but a few days of unseasonably warm temperature may be the culprit. Also, they were planted in an area that tends to stay very moist, but I don't think that caused the bolting. Interesting enough, though, is that it's only at the one end of the row that they are bolting.
Some have been harvested already, but some of the ones that have bolted are still extremely small. If I cut the flower stalk off of them, do you think that the root will enlarge?
