What are the Common Lawn Weeds in North Texas?
Common lawn weeds in north Texas include both grassy and broadleaf weed species. Weeds invade lawn environments that have unhealthy, sparsely growing lawn grass. Lawn weeds are highly adaptable to a variety of adverse environmental conditions including infertile, poorly drained and shady lawn areas. Early identification and removal of lawn weeds will prevent immediate spreading. However, long-term weed prevention requires improving the environmental conditions suitable for a dense, green turfgrass.
Bermuda grass (Cynoden dactylon) is a perennial, creeping, grassy lawn weed that spreads quickly with stolons and rhizomes. This grassy weed is a common turfgrass in southern regions, but an unwanted pest in north Texas, often overtaking more desirable turfgrasses.
Bristly Mallow (Modiola caroliniana) is a perennial, broadleaf weed with light green, shiny leaves growing outward from a central stem. This weed commonly invades recently disturbed soil environments and quickly spreads by seeds and stolons.
Goose grass (Eleusine indica) is an upright, clumping, annual grassy weed that has green leaves that turn white and sliver towards the base. Goose grass thrives in hot summer temperatures, easily out-competing the indigenous and desired turfgrasses in north Texas.
Common Mullein (Verbascum thapsus) is an upright, biannual, broadleaf lawn weed with large light green, hairy leaves. Common Mullein is easily preventable by regular mowing to a height of 2 to 3 inches. Left alone, this weed can grow quickly, 3 to 6 feet in height.
Reseed A Lawn With Weeds
If you are faced with a neglected lawn that’s partially dead and is being taken over by weeds, you may be able to renovate it. Follow up by applying a selective herbicide product that kills common broadleaf lawn weeds while not harming grass. Normally, all weeds will be dead within two weeks. Most deteriorated lawns have a built-up layer of dead and partially rotted grass stems, roots and rhizomes just below the green grass leaves. For small lawns, you can remove thatch with a garden rake. For large areas, go over the lawn with a power dethatcher, also known as a vertical mower or power rake. The soil nutrients most important to healthy grass plants are nitrogen, potassium and phosphorous. Supply these nutrients by applying a commercial fertilizer formulated for starting lawns and lightly rake it into the soil before you reseed.
