Lawn care season has begun in St. Louis but with the new season comes the same threats that can compromise the health of your lawn year after year. One common threat that can be destructive to a lawn is crabgrass. Crabgrass is a grass weed recognized by its coarse texture and pointed leaves that spread out from a central stem. These weeds spread and germinate quickly and cause lawns to become patchy and discolored. Several other grass weed types that are similar to crabgrass can also be troublesome and it is important to be able to identify them to take action. This post is a guide to the different types of grass weeds in the St. Louis area.
The most common type of weed grass is crabgrass with other types that include quackgrass, tall fescue, poa annua, and goosegrass. Smooth crabgrass is a summer annual with light green color and a mass of zigzag nodes. It begins germinating when the soil reaches 55 degrees Fahrenheit and it thrives in weakened conditions such as sunny spots, areas damaged by insects, and areas along sidewalks and driveways. One crabgrass plant has the potential to reach a foot in diameter and produce 150,000 seeds in a single season.
While crabgrass is more common than the other grass weeds, quackgrass, tall fescue, poa annua, and goosegrass can also cause problems for Missouri lawns. Quackgrass looks similar to crabgrass but grows in taller patches with strong roots that make it tough to dig out. Tall fescue is a perennial cool-season grass that grows in clumps with grass blades that can shoot up to two feet in height. Poa annua, or annual bluegrass, is a winter annual that is short and light green in color. Its many variations make it one of the most troublesome and widespread grass weeds in the world. The last grass weed common to Missouri is goosegrass. Goosegrass is a summer annual that germinates within a couple weeks of crabgrass and tends to grow in exposed or high traffic areas. It is whitish in color with flattened stems towards its base. Each of these types of grass weeds can be harmful to your lawn and should be addressed as soon as it is noticed.
