My radishes look great on the outside, but the insides are hollow and kinda spongy. Any idea why?
Radishes with hollow insides
Sounds like you let them get tto big, or let them satnd too long.
I can't remember the variety, but they all seem to be like that, even the smaller ones. Maybe they did stay in too long. Thanks for the info. And we did get some very warm weather early on...
I think you found the problem right there, very warm weather early on.
