When should I plant Mighty Mustard®?
Choose the season that works best for your planting schedule. You can plant in the fall and again in the spring or once per year. In the fall, try planting in September for incorporation in late October. In the spring, plant as soon as you’re able to work the soil. Remember that you must wait at least three weeks after incorporating Mighty Mustard® before you can sow your seeds or plant fruit or vegetable starts. The effects of Mighty Mustard® are cumulative, so the more frequently you plant it, the more your soil benefits.
Why are there three varieties of Mighty Mustard®?
Kodiak, IdaGold and Pacific Gold all contain very different glucosinolates. IdaGold glucosinolates suppress weeds. Kodiak and Pacific Gold glucosinolates are biologically active against insects, nematodes and fungal pathogens, such as sclerotinia and Verticilium wilt.
Can I blend Kodiak, IdaGold and Pacific Gold?
Yes. Based on our experiences, the IdaGold will bolt first, then be taken over by the Kodiak and Pacific Gold.
Can I interseed Mighty Mustard® with other cover crops?
Yes, but you will definitely want to cut the Mighty Mustard® seeding rate in half. And please be aware that Mighty Mustard® may suppress the germination of any other cover crop with which it is seeded. One of our research partners planted a full rate of Pacific Gold with annual rye, and the mustard’s natural systemic herbicide killed much of the rye.
Pacific Gold seed count: 175,000/lb.
Pacific Gold seeding rates:
4 – 6 week growth period: 15 lbs/acre or .5 lbs per 1,000 square feet
8 – 12 week growth period: 10 lbs/acre or .25 lbs per 1,000 square feet
Pacific Gold plant height
4 – 6 week growth period: 1 to 2 feet
8 – 12 week growth period: 5 to 6 feet at full bloom
IdaGold seed count: 110,000/lb.
IdaGold seeding rates:
4 – 6 week growth period: 20 lbs/acre or .5 lbs per 1,000 square feet
8 – 12 week growth period: 15 lbs/acre or .25 lbs per 1,000 square feet
IdaGold plant height
4 – 6 week growth period: 1 foot
8 – 12 week growth period: 4 to 5 feet at full bloom
How much biomass will Mighty Mustard® produce?
Kodiak: 5 to 6 tons per acre
Pacific Gold: 4 to 5 tons per acre
IdaGold: 3 to 4 tons per acre
How to plant Mighty Mustard®
Work up the ground to a good, moist seedbed. Sprinkle or broadcast seeds onto the surface and lightly rake, rototill or harrow them into the soil to a depth of about 1 inch. Follow immediately with light irrigation. If it is seeded shallow, with good moisture and soil temperatures above 50° Fahrenheit, your mustard plants should emerge within 4 to 5 days. Planting in cooler soil temperatures will result in slower emergence.
How much water does Mighty Mustard® require?
If you are growing the mustard to full bloom, total water needs should be about 7 to 8 inches of irrigation. Warmer temperatures increase the need for water.
Optimal growing temperatures
65° - 80° Fahrenheit. Cooler temperatures will result in a slower rate of growth. Warmer temperatures will increase the need for irrigation.
How does Mighty Mustard® weather the cold?
Mustard will withstand a light frost, down to 26° Fahrenheit, and succumb to killing frosts. You have the option of mowing and incorporating the mustard at the first signs of flowering, immediately after it is killed by frost, or the following spring.
Does Mighty Mustard® attract pests?
Flea leaf beetles and cabbage aphids are attracted to Mighty Mustard® plants. Based on our experience, other pests avoid our mustards because they can’t tolerate the plants’ natural “heat” or spiciness. If you have a different experience, please send your story to email@example.com
Incorporating your Mighty Mustard® cover crop
When should I chop my Mighty Mustard® for green manure?
To reap maximum benefits from your Mighty Mustard®, mow the mustard at the first sign of pod set. If you allow the mustard to go to seed, you could wind up with unwanted plants, as mustard can be difficult to suppress. You may also choose to incorporate Mighty Mustard® in the spring, after it has winterkilled. Timing is important, as you must wait at least three weeks between incorporating Mighty Mustard® and planting your crops. If you don’t wait, the glucosinolates that suppress the weeds and soilborne diseases may also suppress your fruits and vegetables.
Why do I need to chop the mustard?
The cell walls of the mustard must be broken for the glucosinolates to unleash their biologically active chemicals. When these chemicals come in contact with water, they act as a fumigant. Chopping the mustard before incorporating it into the soil increases the speed of this natural chemical release.
How do I incorporate my Mighty Mustard® green manure into my soil?
Mow the mustard, then make sure you chop the plants as finely as possible, perhaps running your flail or lawn mower over them a couple of times. Incorporate the green mustard with a rototiller or pitchfork as soon as possible, then water until the top 6 inches of soil is wet. Wait at least three weeks to plant fruit, vegetable or cereal crops.
How long do I have to wait between incorporating Mighty Mustard® green manure into my soil and the planting of my fruits and vegetables?
You must wait at least three weeks! This allows time for the biofumigation properties of the glucosinolates to diminish to the point where they won’t kill your crops.
The research, development and science of Mighty Mustard®
Who developed Mighty Mustard®?
Kodiak, IdaGold and Pacific Gold were all developed by Dr. Jack Brown, Professor of Breeding and Genetics at the University of Idaho. The research team at the University of Idaho’s Soil Biochemistry & Environmental Organic Chemistry, led by Dr. Matthew Morra, has conducted biofumigation research with rapeseed and mustard plants since 1988.

How do the glucosinolates in Mighty Mustard® compare to those in other brassicas?
Glucosinolate levels vary year-to-year, due to growing conditions, planting season, soil fertility, and plant health, so it’s a challenge to find accurate head-to-head comparisons. That said, Mighty Mustard® contains higher levels of glucosinolates than wild mustard and some other varieties of mustard cover crops. Please visit this website for glucosinolate estimates: http://www.grant-adams.wsu.edu/agriculture/covercrops/green_manures/variety.htm
Can Mighty Mustard® replace chemical pesticides & herbicides?
The answer depends on your situation. Some growers have used our mustards to replace chemicals, while others incorporate it as part of their Integrated Pest Management strategies. For more general information about mustard green manures, read http://grant-adams.wsu.edu/agriculture/covercrops/green_manures/index.htm
How does Mighty Mustard® recycle nitrogen?
All 3 Mighty Mustard® varieties have taproots that can grow 2 to 6 feet, depending on the growing conditions. These taproots pull nitrogen from deep in the soil profile, and push it up into the plant’s leaves. When you incorporate chopped Mighty Mustard® into the soil, you then redistribute the nitrogen to the top two feet of soil, making it readily accessible to the roots of your fruits, vegetables and other crops.
Is Mighty Mustard® Non-GMO?
Yes. Mighty Mustard® has undergone third-party evaluation and is verified non-GMO by the Non-GMO Project. Learn more about The Non-GMO Project here: http://www.nongmoproject.org/
Is Mighty Mustard® certified organic?
No. Many certified organic growers petition to grow Mighty Mustard® because to our knowledge, there are no organic mustard cover crops with comparable glucosinolate levels to Kodiak, IdaGold or Pacific Gold.
Is Mighty Mustard® planting seed grown sustainably?
Yes. It is grown by a family of farmers, Pacific Northwest Farmers Cooperative, based in Genesee, Idaho. Our farmers take pride in nurturing and protecting their land through sustainable farming practices.
