One of the easiest ways to bring new life to a garden or back yard is with screen trellises. They'll help dull the sounds of street noise and can be easily detached in cold weather. Sculptural styles also bring a bit of color that will be an additional attraction, even when the plants are dormant. Add one to a backyard corner to create a lovely backdrop for your trailing plants. A tall ornamental style is an attractive accent in your garden even during cold seasons.
