So there I am...finished consuming the last of my first planted radishes. Beautiful round globes, tasty to say the least. Second row in the wait (planted approx 2 weeks later than the first). Then comes the time to refill the radish bowl in the fridge. TOPS. Many are nothing but tops, no globe to speak of. This isn't the first time I have had that happen, but truth be known, I don't know why it does. So here it is: What the heck makes Radishes top out instead of growing a bulb. Heat, water...what?? I know that this place houses many gardeners and I am hoping that someone can enlighten me on this.
