Homemade Weed & Feed for Lawns


Creating a homemade recipe that acts as both a weed-killing agent and a fertilizer for your lawn can be tricky. Corn gluten, which is a by-product of corn milling, is one good solution because it can prevent weed seeds from growing and feed your lawn at the same time. If you have existing, rooted weeds, the corn gluten won't be an effective weed killer and you'll need to use an additional homemade recipe to eliminate the weeds.

Step 1

Purchase at least one 20-pound bag of corn gluten from your local feed mill or grain elevator. The corn gluten is an effective pre-emergent herbicide and acts as a slow-release nitrogen fertilizer (9-0-0).

Step 2

Apply the corn gluten using a fertilizer spreader at a rate of 20 pounds per 1,000 square feet of lawn. Spread the corn gluten into the topsoil with a rake.

Step 3

Water your lawn lightly after applying the corn gluten, but then abstain from watering until the corn gluten sprouts seeds. Try to avoid applying the corn gluten during rainy periods.

Tips and Warnings

  • For best weed-control effectiveness, be sure to apply the corn gluten to your lawn in early spring, before the weed seeds begin to germinate. Don't plant grass seeds for at least 60 days after applying the corn gluten.
