THE BRONX - As the cold weather approaches, Michael Lopez, a supervisor at Home Depot, offers tips on how to maintain outdoor space for winter.

Lopez advises to apply winter guard fertilizer in the fall which kills weeds and dandelions. The fertilizer has a water smart technology so homeowners don't have to water as much.

He says that another way to spruce up the outside of a house and save money is to replace old doors. The doors are more energy efficient and come in various designs.

The Home Depot offers a smart phone feature to let consumers pick which door they would like and drag it over a picture of a house to see what it would look like.
