Triple-Variety Mustard Cover Crop Blend

This carefully selected mixture combines three types of mustard:

• White Mustard

• Brown Mustard

• Black Mustard

Together, they create a vigorous cool-season planting with dense foliage, extensive root growth, and brilliant flowers.

Use the blend as a seasonal cover crop in vegetable gardens, raised beds, orchards, vineyards, and other areas where you want to keep soil covered between primary crops.

Build & Protect Your Soil Between Crops

Leaving garden soil bare can increase its exposure to erosion, nutrient loss, and weed establishment.

Growing mustard as a cover crop helps maintain living vegetation and active roots during periods when your primary crops aren't growing.

Depending on how it is managed, mustard cover cropping can help:

• Protect exposed topsoil

• Reduce erosion

• Add plant biomass

• Contribute organic matter after termination

• Improve soil aggregation and structure over time

• Capture nutrients that might otherwise be lost

• Increase plant diversity within crop rotations

• Keep living roots growing between primary crops

Vigorous Roots for Soil Improvement

Mustard develops an extensive root system that explores the soil beneath the planting.

This root growth can help create channels through the soil while capturing nutrients during the growing season.

When the cover crop is terminated and allowed to decompose, both the roots and above-ground plant material contribute organic matter back to the soil.

Natural Biofumigation Potential

Mustard plants contain naturally occurring compounds called glucosinolates. When certain mustard tissues are finely chopped and incorporated into moist soil, these compounds can break down into biologically active substances.

For this reason, specific mustard varieties and management practices are sometimes used in biofumigation programs designed to help manage certain soilborne pests and pathogens.

Results depend heavily on the mustard species and variety, biomass produced, target organism, timing, soil conditions, incorporation method, and other management practices. Mustard should therefore be considered one component of an integrated soil-management program rather than a guaranteed pest treatment.

Fast Growth Helps Compete with Weeds

Mustard's rapid growth can quickly produce substantial foliage and ground coverage.

A healthy, dense stand helps shade exposed soil and compete with emerging weeds for available:

• Light

• Space

• Water

• Nutrients

For the best weed-suppression benefit, establish the mustard before significant weed competition develops.

Erosion Control & Ground Coverage

Fast-growing foliage helps shield the soil surface from rain and runoff, while the root system helps hold soil in place.

This makes mustard useful for seasonal planting in:

• Vegetable beds

• Raised beds

• Orchards

• Vineyards

• Garden plots

• Open landscape areas

• Areas between growing cycles

Golden Flowers for Pollinators

Allow the mustard to flower and the planting transforms into a sea of bright yellow blooms reminiscent of Napa Valley in spring.

Mustard flowers can provide forage for:

• Honey bees

• Native bees

• Other beneficial insects

• Visiting pollinators

Gardeners can enjoy the brilliant seasonal color while adding another flowering resource to the landscape.

Horticultural Vermiculite Included

The Mustard Cover Crop Seed Blend includes horticultural vermiculite, helping make the seed mixture easier to distribute while providing useful moisture-management properties.

Vermiculite can help:

• Retain moisture

• Improve moisture availability during establishment

• Support aeration

• Hold and exchange certain plant nutrients

• Improve distribution of seeds during planting
