Cynodon dactylon, commonly known as Bermuda grass, is a tenacious and extremely aggressive warm season grass that is actually considered a weed in plenty of lawns. It is highly capable of propagating both through seeding and vegetatively, which means that it could spread from one area in a lawn or a neighboring lawn very easily. It doesn’t really like the shade and thrives in direct sunlight.

Make sure that seeds, compost, and soil in your lawn is free of weeds, and thoroughly inspect fill or topsoil prior to storing it and using it in your lawn. When buying plants, check the area to ensure that it’s weed-free and clean prior to purchasing them and bringing them back home.

- Only fertilize in early fall or late spring, never during the hot season because when Bermuda grass is most active.
