Quaint Name, Nasty Weed
Barnyardgrass is an annual grassy weed found throughout North America. It prefers moist, nutrient-rich soils like those found in lawns and garden beds. It is a coarse, sprawling, purple-tinged annual grassy weed. The grass blades are flat with a prominent vein in the middle, and can also be sparsely hairy. If not mowed, it can reach a height of 1 to 4 feet tall. It is a vigorous grower and can quickly remove important nutrients that your lawn needs, like nitrogen, phosphorus, and potassium, from the soil. Use these easy tips to help control it.
Since Barnyardgrass is an annual grass, which means it will die off with the first fall frost, and doesn't have deep roots, so you can simple pull it out by hand. However, if you have a large problem with barnyardgrass, this may be impractical.
A healthy, dense lawn can help prevent barnyardgrass from becoming established. Feeding your lawn every 6-8 weeks, 4 times a year with Scotts® Turf Builder® Lawn Food will help your lawn stay thick and lush and crowd out weeds like barnyardgrass.
You can also prevent barnyardgrass from appearing in the summer by applying a pre-emergent, like Scotts® Turf Builder® Halts® Crabgrass Preventer with Lawn Food, in the spring.
