To control weeds in a lawn, identify the existing weeds, apply an appropriate week killer and pull remaining weeds. Prevent weeds from growing by mowing the lawn to the right height and applying prevention products to the lawn.
To get rid of and prevent weeds in the lawn, run through the following steps.
- Identify the existing weeds
- Apply weed killer to the weeds
- Pull individual weeds
- Apply a weed preventer to the lawn
- Mow the lawn regularly
Different weeds require different removal techniques, so it is important to identify the weeds growing in the lawn. There are three broad categories of weeds: broadleaf, perennial grassy and annual grassy. Broadleaf weeds describe any weeds that have leaves, such as dandelions and clover. Perennial grassy weeds are grass-like weeds that remain dormant in the winter and come back in the spring. Annual grassy weeds are grass-like weeds that die after each growing season.
To effectively remove broadleaf weeds, spray herbicide directly on individual weeds or patches of weeds using a small pressure sprayer or a small tank sprayer. If there are many weeds in the garden, use a hose sprayer to spray herbicide onto the entire lawn.
Most weed killers cannot kill perennial grassy weeds such as quack grass. To remove these weeds, pull them out of the ground by hand.
To keep annual weeds such as crab grass from coming back after it dies down, apply a weed preventer to the lawn in early spring.
Cutting grass helps it thrive, making it harder for weeds to compete. Ideal grass heights range from a quarter inch to three inches, depending on the type of grass and the climate. Regular fertilizing and watering also helps grass grow strong.
