Common Missouri Lawn Weeds

The best natural defense that a lawn has against weed growth is a strong root system. A strong, thick root system chokes out weeds to prevent them from growing and establishing themselves in the lawn. While proper fertilization and watering techniques promote a strong root system, weeds can still grow even in the healthiest lawn.

The best weed control applications should effectively kill weeds without causing damage to the existing grass and root system. Post-emergent weed applications can have differing effects with some products such as Roundup damaging the grass around the weeds. The weed control applications used by Green T contain a blend of specific herbicides that target weeds without damaging the grass or root system. This herbicide begins taking effect within 24 hours of the application and kills weeds within 7-10 days. Below are the most common weeds found in Missouri.
 


ChickweedChickweed: Chickweed is a low-growing weed that has broad, oval shaped leaves and white, star-shaped flowers that grow alone or in clusters. There are two forms of chickweed in Missouri; common and mouse ear. Common chickweed is an annual plant and mouse ear chickweed is perennial and can survive through the winter.
 


CrabgrassCrabgrass: Missouri has two species of crabgrass; large crabgrass which is hairy and smooth crabgrass which is hairless.
