How to Use Corn Meal As a Herbicide


Corn gluten meal is a product fed to cows, fish, chickens, and even cats and dogs. Corn gluten meal is made from corn, and is sold in either powder or granular form. In addition to being used as a food source, corn gluten meal is an all natural pre-emergent herbicide.

Step 1

Choose a date in the fall and spring to apply the corn gluten meal to your lawn. Try to pick the same dates such as October 30th and April 30th. It will help you remember.

Step 2

Put on a pair of gloves, and clothing you don't mind getting dirty.

Step 3

Place your corn gluten meal in your spreader and apply it to your lawn. Twenty lbs. of corn gluten meal will cover 1,000 sq. ft. of lawn.

Step 4

Double or triple the amount of corn gluten meal if you have a larger area to cover.

Tips and Warnings

  • Do not apply corn gluten meal on a day when rain is expected.
