About Mighty Mustard® Trifecta Power Blend Cover Crop Garden Seeds

Non-GMO Mighty Mustard® Trifecta Power Blend is a diverse mixture of short-season cover crops and can be seeded nearly anytime of year for a quick garden mulch and manure. Annual Trifecta Power Blend mustard seeds are intended for full sun outdoor sowing, broadcast and lightly rake and tamp in nearly any type of garden soil in need to loosening or repair in full sun. Mustard seeds germinate in 5-12 days and mature into a 24-30" tall cover crop with a golden yellow and yellow-white weedy wildflower spread. If mulching back into soil, annual mustard cover crop is best if mowed down 6-8 weeks before planting new crop to allow glucosinolates time to fortify soil. Trifecta Power Blend features Non-GMO Brassica juncea and Sinapsis juncea are hardy short-season cover crops with no serious pests or diseases, grown for its tolerance to extremes, and is often planted for its glucosinolate content which serves as an all-natural garden pest and insect repellent.

The Mighty Mustard® line of mustard cover crop seeds was developed by dedicated plant breeder and University of Idaho professor of Agricultural and Life Sciences, Dr. Jack Brown. Much like all of Dr. Brown's research, Mighty Mustard® was specifically cultivated to better assist the local environments with an even more robust and abundant cover crop, marked with a noticeable ability in preventing broadleaf weeds. Dr. Jack Brown is most notable for his work in reducing a dependency on crude oils, arguing that alternative fuels and biofuels, can be sustained from oilseed crops such as rapeseed and mustard seed. Trifecta Power Blend features an unbeatable mixture.

The mighty mustards are a special group of mustards specifically developed to have higher concentrations of glucosinolates to function as a soil fumigant. That is what gives them the ability to target nematodes and suppress diseases. Regular mustards, like the Farmer’s Favorite Mix, are more traditional mustard strains. They are edible as mustard greens - a southern favorite. Mighty mustards are not for human consumption. The high concentration of glucosinolate can cause digestive distress in some people.

Mighty Mustard® Trifecta Power Blend Benefits

Non-GMO Mighty Mustard® Trifecta Power Blend features varieties specifically bred and cultivated to increase its impact and sustainability as a cover crop. Not only can the Mighty Mustard® line of mustard seeds be sown in the spring as a beneficial summertime companion plant, but are most popularly grown only to be mulched back into the soil as a rich source of season-long nitrogen. Trifecta Power Blend mustard cover crop seeds are a safer, more reliable, source of nitrogen than store bought supplements and additives because there is no risk in burning roots with direct nitrogen contact. And like Daikon radish, Mighty Mustard® seeds develop a deep taproot to break up hardened soils in overgrown and uncultivated grow spaces.

Kodiak, Pacific Gold, and White Gold all contain very different glucosinolates. White Gold glucosinolates work to suppress weeds. Kodiak and Pacific Gold glucosinolates are biologically active against insects, some nematodes and fungal pathogens, such as sclerotinia and Verticilium wilt. Mustard cover crops help significantly control pests because they contain a higher amount glucosinolate than other brassicas, and this chemical compound wards-of harmful insects, especially when the plant cells are ruptured when the plants are mowed down. Known for their rapid fall growth, Mustards makes a great weed suppressor because weeds don't have a chance to take of the soil and grow. Mustard"s roots burrow deeper than other scavengers for nutrients, which also help ward-off soilborne pathogens. Expect about eighty percent soil coverage.
