In the fall, mulch your radishes with leaves or straw to protect them from any sudden changes in temperature.

How do you cover a daikon radish crop?

Plant daikon seeds a little earlier than other over-wintering cover crops to give it time to grow a thick leaf canopy. Aim for 4 – 10 weeks before the first frost – late August in cooler climates, early September in warmer ones. The seeding rate is 10 – 15 pounds of radish seed per acre.
