"You can find solar post lanterns in different varieties and styles, including some that fit directly on your deck posts for $20 or $30 each," Mr. Hastings said. "Low-voltage accent lighting is available online or at home improvement stores at a low cost and can give you a nice evening view of your yard, even when you are inside."
"You can buy a prefabricated fire pit to add warmth to your patio and to use the space, even on cooler evenings," Mr. Hastings said. "Another option is to buy a small wall-mounted or corner fountain. They start at $200 or so and are usually easy to install."
