When teaching turfgrass ecology in a separate class, I like to make sure students recognize the "short-term" effects of spraying herbicides for weed control in landscapes. The long-term solution is to alter the environment once a weed is controlled to make the desirable landscape plants/turfgrass more competitive than the weeds consistently encroaching. Please give 2 examples where a homeowner or landscaper could alter the environment to be more favorable for landscape plants/turfgrass than weeds? Explain how the change in environment will benefit landscape plants/turfgrass while limiting the growth of weeds
