We just bought a house with a great lawn, but I want to be sure to take care of it so it looks nice in the neighborhood. At the beginning of each spring, I aerate the lawn so the water can betterpenetrate the soil. Then, I mow the lawn once a week to a good height, and I check the sprinkler system to make sure the grass is completely watered. Otherwise, we'll see dry brown spots in the lawn after a while. Next, I fertilize the lawn twice a year with a weed and feed mixture which helps green up the grass and kill broad leaf weeds like dandelions. I sometimes have to use an insecticide to kill bugs that are eating the roots of the grass. Finally, I trim the edges of the lawn along the fence and the sidewalk to make everything look really sharp and tidy.
