If smaller, keep them damp and see if they will grow a bit more. If some have bolted, it is likely the rest are not far behind. You can take a finger and push some soil away from the bulb and see how they are looking. What variety? I have had good luck with Cherry Belle. Some of the other varieties ....... not so good. I have found it pays to carefully place the seed when planting to 2 inches apart both ways. If you give them room they will make a better root quickly. Good luck.
Thanks, I'll keep that in mind.
I am not sure what variety. The kids came home from a birthday party with little Disney planting kits. It just said Radishes, and the picture was of a round radish with a red bottom and white top. We tossed the tiny pots and I had them put the seeds in the ground instead. I guess it is possible that they forgot to water them over the weekend while I was not there.
