Details

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%

Coverage:

  • 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.

  • From Di at 7/15/10 8:35 PM
    • does this KILL existing dandelions and clover and broadleaf?
      how much would I need to purchase for 2 acres?
    • Corn gluten is a pre-emergent - it kills weeds before they can sprout. It will not kill existing weeds in your lawn. A 20 lb. bag will cover 1000 sq.ft. of lawn.
    • Do you find this question helpful?  Yes  No
  • From Jim at 8/28/10 10:00 AM
    • Can this be applied in the fall (Michigan) and be effective the following spring?
    • The recommended seasonal applications for corn gluten are spring and fall. Corn Gluten Meal is effective as a pre emergent for about 6 weeks, providing the soil is dry after application. After that is becomes a fertilizer. Since, generally, fall is cooler and moister than late spring, applying CGM in the fall, for weed suppression, would not work as well as it would in late spring.
    • Do you find this question helpful?  Yes  No
  • From Dave at 11/29/10 7:01 AM
    • So let me see if I understand this correctly.Corn gluten is only a pre-emergent as long as it does not get wet?

    • Corn gluten meal works by inhibiting root formation in weeds at the time of germination. It doesn't inhibit roots of mature plants or transplants unless it is used at a very high rate of 80 pounds/1000 sq. ft. or more. Weeds germinate and form a shoot, but no root, inhibiting growth. A short drying period is required after germination, because too much water may allow the plants to recover and form roots.

      Timing is the key to success when using corn gluten meal. It should be applied before the targeted weed emerges above the soil. Since a drying period is required after application, you should make sure no rain is forecast for a few days after application.

  • From John at 3/21/11 9:54 AM
    • How long after applying corn gluten do I have to wait before sowing grass seed?
    • Make sure you wait 60 days after application before spreading grass seed.
    • Do you find this question helpful?  Yes  No
  • From Jaime at 3/29/11 2:20 PM
    • Do you use a broadcast spreader with this and is so, what setting should be used?
    • Corn gluten can be broadcast by hand or by using a spreader. The spreader setting depends on the brand of spreader. A Scott spreader should be set at 12 - 13. You can tell pretty easily once you start spreading if the setting is too high or low.

  • From Doug Boone at 4/6/11 9:46 AM
    • I have seen dogs eat corn gluten organic fertilizer. Is the product safe for dogs to eat?
    • Bradfield Organics Corn Gluten Organic Fertilizer is safe should the dog eat any of it. However, it's a waste of good fertilizer. Once corn gluten is applied, it should be wetted. This breaks down the granules and the dog will be less likely to try to eat it.
    • Do you find this question helpful?  Yes  No
  • From Diana Palumbo at 5/8/11 8:57 AM
    • I live on Long island and would like to clarify a schedule for application. If I plan on seeding my lawn in the fall I assume I would do that first in Sep? Would I then wait 60 days to apply the corn gluten meal? And then reverse the process in the spring? We are trying to build our lawn and kill the dandelions and crabgrass that are taking over. Thanks
    • Yes, you have the right idea with regards to scheduling corn gluten application. The fall application is intended to suppress hardy over-winter weeds. The spring application is more important because most weeds germinate in late winter and early spring. Your plan to seed in early September will give your new lawn time to get established, so you can focus on the weeds in spring. If you wait to seed until spring, it's a tigher window to try to supress weeds and still leave time for the new grass seeds to germinate and sprout.

  • From Susan at 3/12/12 7:21 AM
