Corn Gluten is a naturally occurring substance, which provides nitrogen for a healthy lawn while also inhibiting the growth of weeds. Since most weeds spread by seed corn gluten will kill weeds before they sprout. Corn gluten is a natural, non-toxic replacement for chemical-based 'weed n feed' lawn treatments.

Features & Benefits:

  • Slow-release nitrogen fertilizer (8-0-0)
  • Will not burn plants - nutrients released over time
  • Feeds lawns naturally and helps build strong turf
  • Apply in spring for a natural pre-emergent herbicide
  • Dry granular form makes it easy to apply by hand or with a spreader
  • Safe for people, animals and the environment
  • Only organic, GMO-free Corn Gluten Meal on the market
  • Formulated to meet USDA National Organic Program (NOP) standards
  • Certified organic by the Organic Materials Review Institute (OMRI)
  • Available in a 50 lb. bag

Guaranteed Analysis:

  • Total Nitrogen (N): 8%
  • Water Insoluble Nitrogen: 7.25%


  • Initial treatment: Apply 20 lbs per 1,000 square feet of lawn, garden or flowerbed area each Spring and Fall.
  • Subsequent treatments: Apply 10 lbs per 1,000 square feet. Corn gluten can be applied by hand or by using a spreader.
  • Spreader setting: A spreader should be set at 12 - 13.

Organic Fertilizer

As a fertilizer, corn gluten meal is a rich natural source of nitrogen (8-0-0). Apply any time of year to fertilize your lawn, shrubs or transplants. Nitrogen is released steadily over a 3-4 month period after application. Nutrients come from organic corn gluten meal with 100% active ingredients. No animal manure or fillers.

Natural Weed Control

Corn gluten also acts as a pre-emergent weed killer. It inhibits seed germination by drying out a seed as soon as it begins to sprout. These qualities make corn gluten a natural 'weed n feed' product.

Apply to lawns in early spring, around when forsythia and early spring bulbs are in bloom, before weed seeds start to sprout. Apply again to lawns anytime in the Fall. For transplants, apply corn gluten immediately after transplanting vegetables and shrubs to prevent weeds from sprouting in soil and competing with your plants. For best results apply when there is no rain in the forecast for 48 hours.

Controls most broadleaf weeds:

  • Dandelions, Clover, Crabgrass, Kentucky Bluegrass, Quack grass, Curly Dock, Green Foxtail, Giant Foxtail, Pigweed, Black Nightshade, Orchardgrass, Black Medic, Barnyardgrass, Shattercrane, Purslane, Wooly Cupgrass, Lambs Quarters, Buckhorn Plantain, Creeping Bentgrass, Catchweed Budstraw, Velvetleaf, and more

Safe for people and animals:

This organic corn gluten is composed of 100% granulated corn gluten meal with nothing added, so children and pets can play on the lawn immediately after application. When used as directed, corn gluten will not harm beneficial insects, soil organisms, pond or stream life.

Research from Iowa State University:

Corn gluten meal works by inhibiting the root formation of germinating plants. It generally does not inhibit the roots of mature plants or transplants until your reach very high rates (80 pounds/1000 ft2 or higher). It should be applied before germination of the weeds. The weed will germinate and usually forms a shoot, but does not form a root. After germination, a short drying period is needed to kill the plants that have germinated but have not formed a root. Timing is critical. If it is too wet during germination, the plants will recover and form a root. (This is also true of chemical pre-emergence herbicides).

For best results, choose a time when rain isn’t predicted over the next few days, water it in well and allow it to dry out; seeds will try to sprout, then die. Don’t apply it if its going to rain non-stop for two weeks; you need a dry stretch after watering. It will remain effective for about 5 to 6 weeks following application. Corn gluten will kill all germinationg seeds, including grass seeds, so you can’t sow a new lawn at the same time; wait six weeks for the gluten to lose its herbicidal effect.

It does not work well with seeded garden crops unless they are seeded deeply (radishes seem to be the exception and there may be others). Transplants or mature plants generally work well in beds treated with corn gluten. Some producers put down a band, work it into the upper inch of soil, and then put the transplant in the band.

In garden and crop production, growers generally work out their own system, depending on their understanding of the crop they are growing and the weeds they are trying to control.

Caution: Do not apply corn gluten to recently seeded areas. Wait for 60 days after applying grass seed. Corn gluten will inhibit the growth of any newly germinated grass seeds.


Corn Gluten Meal is an organic fertilizer and natural weed control solution.

    • We have 2 established asparagus beds which are over-run with the weeds listed as being susceptible to corn gluten meal. But what about our asparagus?
    • Corn gluten prevents new weeds from sprouting by drying them out as they germinate. Corn gluten does not eradicate existing weeds. For your asparagus beds, we suggest hand pulling the surface weeds, then mulching the bed, leaving a clear space above the root crowns where the new asparagus emerge. Presumably you have already clipped down last season's stalks to about 1" above the ground. These stubs help you know where not to mulch, since the new shoots will be coming from amid the stubs.

    • Would this product benefit my vegetable garden plants?
    • Corn gluten will prevent seeds from germinating, including vegetable seeds. (Some larger seeds such as corn, beans and squash may grow through corn gluten in the soil.) Corn gluten will not harm established plants, and does have value as a fertilizer, but if you plan on sowing seeds in the months ahead then it's not a good idea to use corn gluten in vegetable beds. There are many other sources of nitrogen for vegetable gardens which are 'seed safe'.
