Mustard Sinapis alba Produces large amounts of biomass containing high levels of glucosinates that break down into isothiocyanates, compounds toxic to nematodes and soil-borne disease-causing organisms.

Allow the plants to grow fairly large to maximize the glucosinate concentration and then chop fine and incorporate into the soil. Allow 2 weeks for the plant to break down before planting a new crop. Plant 1½" deep in a firm moist seed bed at 15-20#/acre, 1#/1000 sq ft.

As cover crop: Can be planted year-round, but best as a fall-planted cover crop to retain nutrients, suppress weeds and improve water penetration. Plant in the spring as a green manure and to suppress nematodes and diseases.

Note: We cannot ship this item to the Willamette Valley.

Additional Information

Farm Seed

Unless otherwise noted, our legume seed is sold “raw”: it has not been inoculated with the appropriate bacteria in a process called rhizocoating.

Organic Seed

We are a MOFGA-certified organic repacker and handler of seed and feed.
All our seed is untreated.

Organically grown seed is labeled OG.
The label ECO after the variety name describes non-certified seed grown without pesticides, herbicides or chemical fertilizers on farms which maintain an active soil-building program. Some farmers eschew certification for a variety of reasons, ideological, economic and otherwise.
