Is there away to kill the moss in my lawn without killing the grass?
—Jake, Nashville, TennesseeA: Roger Cook replies:
There are several moss killers on the market that you can apply to the lawn. These work for the short term, but moss will return. Moss is an indication of an acidic lawn or too much shade on the lawn. Do a soil test on the lawn and apply lime to reduce the lawn's acidity. To reduce shading, check trees around the area and prune or remove them as needed.
