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.

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

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.

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

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.

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.
