A well-maintained lawn is the first defence against the weeds in your turf. For a thick, dense lawn– fertility, irrigation, and consistent mowing are important. Thick grass is going to prevent weeds from growing on your lawn. Weed seeds are opportunistic, sitting idly by until a small space, and a little sunlight is provided to allow them to begin developing.
Weeds mostly reproduce from seeds, and most weeds are very active seed producers. In every lawn, there is typically an abundance of weed seed just waiting for the right conditions to start growing and fight for space with your lawn. However, such weeds spread from runners that may grow above ground or below ground, such as common bermudagrass. At intervals, the runners start new seeds, sending down roots and then shoots, probably taking over a whole field very rapidly.
