I figured there was a reason why nobody had already started a radish thread—the interest just isn't enough—but still thought I'd try, since I'm an avid radish grower.
My favorite part isn't even the harvesting, but the growing process. They're so easy to grow, and so fun as well. Last year I got a good harvest of 'Early Scarlet Globe.' The taste was ok, but they grew very well. I only had to manually water them once (when giving them fertilizer). Once I placed the germinated seeds into the ground, the weather took it from there, excluding me fertilizing them once, as mentioned above.
