Water conservation is vital to any green plan while landscaping is important to the environment as well as curb appeal. Plants play a vital role in air quality by consuming carbon dioxide and producing oxygen. Turf offers additional benefits such as trapping dirt, dust, and other pollution in rainwater runoff. Trees offer shade and reduce heat island effect. Many attractive native plants have minimal water requirements once established and often only need irrigation in extreme drought. Often native plants suffer from irrigation when incorporated into landscape with conventional plantings.
