Growing Tips
Succession-plant every 2 weeks for a continuous harvest; radishes bolt quickly in warm weather and become pithy.
Harvest promptly at maturity; leaving radishes in the ground too long results in cracking, woodiness, and strong flavor.
Use daikon radish varieties as a fall cover crop to break plow pans and scavenge nitrogen from deeper soil layers.
