Homemade Pre-Emergent Weed Killer


There are several different ways to kill weeds once they have emerged among your grass and plants. Some of these methods can actually harm the grass and plants. It is much better to stop the weeds before they even have a chance to grow. You can do this using a simple home remedy. This remedy is safe to use around children and pets, and won't cost you that much to implement.

Step 1

Circle March 15 and August 15 on your calendar. According to Pesticide.org, these are the best dates to apply your corn gluten meal.

Step 2

Put on a pair of garden gloves and prepare to go to work.

Step 3

Sprinkle the corn gluten meal at a rate of 12 to 20 lbs. for every 1,000 square feet of lawn you want to cover.

Step 4

Rake your yard so that the corn gluten meal is mixed in with the top 1/4 inch of the soil.

Step 5

Soak your lawn with the water from your garden hose as soon as you are done raking. Then let it completely dry out before watering again. This causes even more stress to the weeds.
