Inexpensive Way to Kill Lawn Weeds


Lawn weeds can take over your grass if you are not careful. Weeds grow quickly and rob your grass of the nutrients it needs from the soil. Many homeowners treat their lawn weeds with a chemical herbicide, but this can often be expensive, and using chemicals can also pose health risks for your family members and pets. Some home remedies can be used to promote good health and save you money.

Step 1

Set the blades on your lawnmower to mow at 3 to 3 1/2 inches and mow your lawn. This will ensure that the grass blades are higher than the weed blades. The weed blades will be starved of sunlight as they will be in the shade of the grass blades. This will cause the weeds to slowly die off.

Step 2

Stop watering your lawn frequently. According to Rich Soil, grass roots grow deeper than weed roots. Watering less frequently will starve the weed roots of water, while the grass roots continue to get water deeper in the soil. For this method to work, you must water deeply when you do water your lawn.

Step 3

Lay black plastic over your lawn. You can use black trash bags. Let the plastic remain on your lawn for two to three weeks. The sun will heat the black plastic and burn the weeds. It will also starve the weeds of sunlight so that they die off.

Step 4

Fertilize your lawn to get it back to good health. Fertilizing your lawn leads to healthy grass that smothers any weeds before they have a chance to grow. A healthy lawn is the best way to keep weeds away. You can fertilize inexpensively by adding 1 tbsp. of Epsom salt to every gallon of water. Then water your lawn with it once per month.

Tips and Warnings

  • Items such as bleach and water will kill weeds, but they will also kill your grass.
