During the cold and freezing months avoid walking, playing, parking, and driving on the grass. When the grass is brown and short it can be easy for people to forget that it should not be walked on. Try to prevent very much foot traffic on your winter lawn. Grass is relatively resilient, but it will have a difficult time recovering if a path becomes well worn across the lawn. Keep your sidewalks cleared of ice and snow so that you and your guests will not be tempted to cut across the yard. Never allow anyone to park a truck or a car on your lawn. Even the smallest vehicle will leave impressions in the soil and kill off the grass that is underneath the tires. Using the lawn as a parking lot is the fastest way to kill the good grass and make room for crabgrass and other types of weeds.
