What Is Annual Bluegrass?
Annual Bluegrass is a weedy grass that looks a little yellow and has white seed heads. It is a species of Bluegrass that does not tolerate hot weather. It grows well in the Spring, produces a lot of seeds, dies in the Summer, then sprouts again from its seeds, so it can return next Spring.
What Causes Annual Bluegrass?
Annual Bluegrass likes to sprout in bare areas, especially along driveways and walkways. If those areas are damaged with snow plows, cars, or improper String Trimmer Edging, then Annual Bluegrass will inevitably sprout there. It will also grow in any bare areas of the lawn.
What Can Be Done About Annual Bluegrass?
There is not much that can be done about the Annual Bluegrass that you currently have. It will die naturally when the weather gets warm. We do have recommendations to prevent it from sprouting in the future.
- Seed any bare spots in the Fall.
- Mow your lawn high to shade the soil surface and prevent weed seeds from germinating.
- To thicken your lawn, Slice Seed in the Fall, which is the best defense against weeds.
- Do not water more than 3-4 days per week, as watering daily encourages weeds to sprout.
