How to Choke Out Lawn Weeds

Overview

Lawn weeds thrive in infertile, unhealthy lawn grass environments. Choking out weeds from a lawn requires optimizing the health of the lawn and creating a full, vibrant turf grass. Existing weeds should be physically removed or chemically treated, however, this is only a stopgap measure. Without altering the fundamental lawn environment through proper maintenance and cultural practices, lawn weeds will return.

Step 1

Remove existing, isolated weeds from the root using a small spade gardening shovel. Do not use weed remains for compost.

Step 2

Apply a selective weed herbicide, using a spray bottle, over lawn areas with extensive weed growth. Selective herbicides target specific species of weeds and generally do less damage to surrounding plants.

Step 3

Trim back any adjacent plants that block direct sunlight from reaching the lawn using outdoor trimmers. Weeds thrive in low light and shady conditions.

Step 4

Sprinkle lime over the lawn using a spreader to increase the topsoil's pH. Weeds can survive in a wide range of pH values, whereas grass prefer higher pH soils.

Step 5

Mow the turf grass to a height of 2 to 3 inches using a lawn mower. Higher top growth facilitates deeper grass root depth, allowing for a more full and resilient turf grass.
