Johnsongrass and crabgrass are invasive weeds that can overtake your lawn. Crabgrass is a low-growing grass most often seen in lawns, flower beds, and vegetable gardens. While you may find Johnsongrass growing in your lawn, it will also grow in pastures, crop fields, and the edge of the road. Johnsongrass is much coarser than crabgrass. If left alone, Johnsongrass can grow up to 8 feet tall. 

Mowing is one of the most important ways to maintain your lawn because it encourages grass to grow horizontally, creating a fuller, more uniform yard. On top of mowing your lawn, you’ll want to routinely fertilize your lawn, water it regularly, and take care of pests the moment they arise. 

Burning is not a recommended method for controlling foxtail grasses. In a large pasture scenario, the fire moves too quickly through the weeds to effectively burn and kill the seeds, meaning they will resprout eventually. If your lawn is overrun with foxtails, it’s best to consult a lawn care professional for suggestions on how to permanently remove it from your property.

You should add 1 to 4 inches of mulch, depending on your garden type and needs. Keep in mind that no amount of mulch can completely prevent weeds, but a heavier coverage (closer to 4 inches) can suppress weeds enough that you are only seeing them sprout every few weeks. Finer mulch prevents weeds more effectively than large mulch, so if you’re using mulched leaves or shredded bark, 1 to 2 inches will likely suffice, while 3 to 4 inches is best for larger mulch, like bark chips or straw.
