When I lived in Poland, we would grow radishes all Summer long. This was the easiest crop to grow and super fast. Now, I live in California and I am not having much luck with radishes. They sprout fast, but then just sit and if they grow head, it takes forever and it does not taste well. I recently had them in a keyhole garden, with compost, manure, mulch all over, full sun, etc. everything grows fantastic there besides radishes.
From my experience with radishes they are easy to grow, but I am having no luck. What am I doing wrong? Is there a trick?
