Wicked Tuff Turf Winter Rye Grass Seed

Ran out of time to plant this fall? Winter rye is the one cover crop you can still get in the ground — it sprouts in near-freezing soil.

Old Cobblers Farm™ Wicked Tuff Turf Winter Rye (Secale cereale) is a cover crop — a plant grown to protect and improve soil between cash crops — and it is the most cold-hardy one there is. It germinates in soil as cold as 34°F, so it can be planted well after other cover crops have missed their window, and it survives the harshest northern winters.

Over winter, its dense, fibrous root system holds soil in place through freeze-thaw cycles and snowmelt, preventing erosion. Come spring it regrows fast — 3–5 feet of “biomass” (plant material) — which you can terminate as a weed-suppressing mulch for no-till planting or work into the soil as “green manure” (a crop turned under to feed the soil). Rye is also allelopathic, meaning it releases natural compounds that suppress the germination of weed seeds. Note: this is a natural weed-suppressing trait of the living/decomposing plant — it is not a herbicide product.

Key Benefits

•     Most cold-hardy: germinates at 34°F and overwinters where other cover crops fail.

•     Latest planting window: goes in later in fall than any other cover crop.

•     Stops erosion: dense fibrous roots hold topsoil through freeze-thaw and snowmelt.

•     Natural weed suppression: allelopathic compounds curb weed-seed germination.

•     Builds soil: heavy spring biomass adds organic matter as mulch or green manure.

Best Uses

•     Fall/winter cover crop and erosion control

•     No-till mulch and weed suppression

•     Green manure and soil organic-matter building

•     Late-fall planting after cash-crop harvest

•     Cover-crop cocktail mixes with legumes and brassicas

Important Notes

•     ⚠ Agricultural cover crop, NOT a fine residential turf lawn: winter rye is grown to protect and build soil and is terminated in spring — it is not a residential turf grass.

•     Terminate in spring at early heading: roll-crimp for no-till mulch, or mow/incorporate for tillage systems.

•     Allelopathic weed suppression is a natural plant trait, not a herbicide product.

•     Seed only — not a fertilizer.
