No-Till Garden Farm and Garden Cover Crop Mix Seeds
Brand: Mountain Valley Seed Company
- 9-Seed Cover Crop Mix — Non-GMO & Heirloom — Includes Austrian Field Pea, Hard Red Winter Wheat, Triticale, Daikon Radish, Hairy Vetch, Crimson Clover, Berseem Clover, Yellow Mustard, and Collard Greens. This blend supports soil enrichment and weed suppression.
- Soil Health Benefits — Naturally fixes nitrogen, reduces erosion, improves tilth, and aerates soil. Deep-rooted radish aids in breaking up compacted soil; legumes restore essential nutrients for healthier crops.
- Versatile Growth — Matures in 30-70 days, suitable for no-till gardens, raised beds, containers, and large farms. Some varieties may overwinter in mild climates.
Best for: Gardeners and small-farm growers who want a diversified, nitrogen-fixing mix that can be used in multiple planting seasons. Choose this if you need a broad, high-diversity blend to improve overall soil structure and weed suppression in organic setups.
Limitation: Some blends may overwinter in milder climates, which could require monitoring for spring re-seeding in colder regions.

Buying Guide: Organic Cover Crop Seed Choices
- How to choose by climate: If you live in zones with cold winters, favor winter-kill varieties to ease spring prep. In milder zones, consider mixes with components that overwinter to maintain soil benefits year-round.
- No-till compatibility: For no-till gardens, pick mixes labeled as no-till or no-mow, and look for nitrogen-fixing legumes to maximize soil health without tillage.
- Soil goals to match: Are you aiming to fix nitrogen, improve soil structure, suppress weeds, or attract pollinators? Match blends to your primary goal while balancing secondary benefits.
- Seed diversity vs. manageability: Highly diverse mixes provide broad benefits but may require more planning. Simpler blends are easier to manage for beginners.
- Size and coverage: Consider your garden area and bed size. Some mixes cover large areas quickly, while others are better for small plots or container gardens.
