One way to help save energy at home is to plant smart when it comes to landscaping around the house. Avoid putting in plants that can grow too tall on the south side of your home. These plants can block sunlight in the winter months, which means your home can’t take advantage of the ambient light and heat. And plant dense evergreen shrubs all around the house. They look good all year long and also naturally insulate to protect your home from the cold air outdoors.
