Very carefully. You should be cautious when using any of the above methods, as any one of them could lead to you accidentally killing desired grasses and plants. However, there are selective herbicides that can target certain plants over others. Look for a product that only affects the type of weeds you want to eliminate and spares the plants you want to keep.

Choosing fertilizers: slow-release for steady nutrients, organic for eco-friendliness, or specific blends for soil deficiencies or grass types.

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. 

Clover is a sustainable, low-maintenance alternative to turfgrass, allowing homeowners to put away the mower while enjoying a lush and consistent lawn. The plant also attracts pollinators, adds nitrogen to low-nutrient soil, and holds up in a range of climates. Consult a local lawn care professional to determine whether replacing your grass with clover is right for your yard.
