The answer to 'grass invasive plants' is that invasive grass species can quickly spread and take over your lawn, outcompeting the desired grass types. Common culprits include crabgrass, quackgrass, and Bermuda grass. Symptoms include patches of thick, coarse grass that spreads rapidly and chokes out your lawn. To solve this, you'll need to identify the specific invasive grass, then take steps to remove it and prevent future infestations.
For minor invasions, you may be able to DIY by hand-pulling the weeds, applying selective herbicides, or overseeding with a dense, vigorous grass variety. However, for severe infestations or if you're unsure of the best treatment, it's best to call in a professional landscaper. They can properly diagnose the issue, recommend the right products and techniques, and ensure the problem is resolved efficiently and effectively.
