Brassica Classic Trio Cover Crop Seed Mix

Brassica Classic Trio Cover Crop Mix — Daikon Radish, Rapeseed & Turnip for Soil Compaction Relief, Drainage, and Weed Suppression

This 3-species Brassica Classic Trio Cover Crop Mix combines Daikon Radish (40%), Rapeseed/Canola (30%), and Turnip (30%) into a powerful cool-season cover crop designed to reduce soil compaction, improve drainage, suppress weeds, and produce forage biomass. Ideally sown in late summer or fall to winter-kill naturally at temperatures below 28°F — no termination required. May also be planted in spring to prepare for summer-sown crops. Non-GMO, Open-Pollinated, Annual. 40–60 days to termination.

Note: This mix is not ideal for southern states. Brassicas are cool-season crops that develop best in cool and temperate climates (Zones 2–8). Not intended as ornamental groundcover.

Mix Composition

What This Mix Does for Your Soil

• Reduces soil compaction — deep taproot habit breaks up clay soils and creates a better seedbed for spring; highly recommended for no-till practices
• Improves drainage and moisture retention — increases organic matter to retain moisture longer and enable better nutrient distribution.
• Suppresses weeds — dense canopy covers soil between seasons, preventing weed establishment before winter.
• Produces forage biomass — forage and grazing-friendly; supplement with additional roughage for a complete diet
• Winter-kills naturally — all three species winter-kill below 28°F; ideal for fall planting with no mechanical termination needed
• Disrupts pest life cycles — best grown between seasons where non-brassica vegetables are grown; avoid planting before brassica crops

Termination

Winter Kill (preferred for fall planting): All plants winter-kill below 28°F. Sow in late summer or fall and allow frost to terminate naturally.

Till or Turn Under (spring/summer planting): Mow and till or turn under before flowering. Grow for 35–40 days before termination or expected frost.

Growing Notes

Clear the growing area of weeds before sowing. Broadcast at 1 lb per 4,356 sq ft (10 lbs/acre) or drill at 1 lb per 5,445 sq ft (8 lbs/acre). Plant up to ½ inch deep; lightly rake into soil. To boost biomass production, fertilize at planting. Optimal growing temperature: 65–75°F. Full sun to partial shade. Germinates in 5–10 days. If growing for grazing, allow enough plant material to establish before grazing — early grazing limits root growth.
