Product Overview
Jonathan Green Corn Gluten Weed Preventer plus Lawn Food feeds the lawn while preventing crabgrass, dandelions, and over 25 other broadleaf and grassy weeds. For optimal results, apply early in the spring—between March and early May—before weeds germinate. For a weed-free organic lawn year round, apply corn gluten meal in early and late spring and again in early and late fall.

The key factor in achieving great weed control results with this product is the proper timing of the first application. This weed control must be spread on established turfgrasses before the weeds germinate because it is only effective before weeds break the surface of the soil. Do not use this product when seeding because it will hinder the new grass seedlings from germinating. Based upon the organic nature of Corn Gluten Weed Preventer it may take a few seasons to control severe weed populations.

  • 10-0-2

  • Pre-emergent

  • Corn Gluten Meal, Nitrogen, Soluble Potash. Derived from: corn gluten meal, urea, and sulfate of potash.

  • No

    • After applying Corn Gluten Weed Preventer – wait 60 – 90 days to plant grass seed
    • After seeding – wait 45 days to apply Corn Gluten Weed Preventer
  • This product can safely be applied with any of our soil amendment products. We don’t recommend applying two of our weed controls or fertilizers together, as you risk burning your lawn. You can, however, apply two of these products together if one has fertilizer and the other one doesn’t. The rule of thumb is: if two products have different functions, it is usually possible to apply them together.

  • Apply to a dry lawn a day or two after mowing.

  • Although Corn Gluten Weed Preventer plus Lawn Food is safe for kids and pets, it works best when applied, watered in, and allowed to dry for 2 to 3 days.

  • 90% Slow release: feeds the lawn for 2 – 3 months.

  • For improved weed control and greening apply up to 4 times a year: in early and late spring, and early and late fall.

  • Our recommendations for storing your weed control:

    Place it in a cool dry place, off of the ground, out of direct sunlight, and keep it away from moisture. Keep bags (especially that have already been opened) containing unused product in a locked storage area inaccessible to children and pets. Do not store near feed or foodstuffs.

     

    To prevent cross-contamination, do not store near open containers of fertilizer, seed or other pesticides. Under these conditions, weed controls will last at least two years.

    • Carefully read all instructions prior to application
    • Wash hands thoroughly with soap and water after handling and before eating or drinking
    • Do not apply near water, storm drains, or drainage ditches.
    • Do not apply if heavy rain is expected.
    • Apply this product only to your lawn or garden and sweep any product that lands on the driveway, sidewalk or street back onto your lawn or garden.
    • Be aware of local ordinance requirements concerning lawn fertilizer applications. “Black out” dates may limit or prohibit lawn fertilizer applications from late fall to early spring in certain areas.
  • Always read and follow the product label before use.

How to Apply

Apply

For Lawns:

  • We recommend using a spreader to evenly distribute the product onto your lawn.
  • Check to make sure the spreader opening at the bottom of the hopper is closed.
  • Set the spreader according to the recommended setting on the packaging or use our Spreader Settings Tool above.
  • Apply around the perimeter of the lawn to establish a turning area. Then run the spreader back and forth within the area outlined by your first perimeter application. Always allow overlap to avoid gaps in coverage.

For Gardens:

  • Spread Corn Gluten Weed Preventer on the surface of the soil after flowers or other plants have been planted.
  • Do not till it in. Incorporating this product into the soil will hurt the roots of the flowers, vegetables, and landscape plants in the garden.

Post-Application

  • Sweep any excess granules off of hard surfaces and back onto the lawn.
  • For best results, irrigate the treated area after application for 15 to 30 minutes and then allow it to dry for 2 to 3 days. Excessive rainfall or irrigation may require re-application for effective weed control.
  • Do not seed for 60 to 90 days after application.
