Cover crop radishes have gained much traction in recent years, especially in no-till systems, because of how well they break up compacted soil. Winter kills them where temps regularly get below 20 F. Residue decomposes quickly and releases its nitrogen early. Channels created by radish roots improve infiltration, drainage, soil warming, and growth of the next crop’s root systems. Other advantages of cover crop radishes include rapid fall growth, weed suppression, high biomass, excellent scavenging of nutrients, and suppression of root knot nematodes. Generally good eating quality, but expect more variability than with radish varieties selected for food. Sow with caution if there are harlequin bugs in your area; one strategy for fighting harlequin bugs is to ensure that at some time of year there are no crops in the radish family for the bugs to feed on. Sow alone at 1/4 lb per 1,000 square feet, or mix with other cover crops.
