Cover Crop / Cool season

Oilseed Radish Cover Crop

Short-window cover crop for soil loosening and fall bed cover.

Grown for root biomass, not table radishes.

Seed spacing and maturity

Can I plant this now?: Use your local last-frost, first-frost, and soil-temperature checks before treating this crop as plantable today.
Start indoors or direct sow?: Direct sow into the final bed when the soil temperature, seed depth, and moisture are ready.
How much space?: 3 inches in-row spacing, 8 inches between rows, and 0.5 inch seed depth.
Best companions?: Use crop-family rotation first, then pair with compatible timing, spacing, and canopy size rather than relying on a simple companion chart.
Common failure modes?: Because it is a mustard-family crop, account for it in brassica rotations. Moderate water while establishing. Loose to average soil; taproots help open compacted beds.

Sun: Full sun
Water: Moderate water while establishing.
Soil: Loose to average soil; taproots help open compacted beds.
Watch: Because it is a mustard-family crop, account for it in brassica rotations.
