A well designed yard needs less water and maintenance, and saves money. Native vegetation competes well with weeds and other pests. Emphasize plant diversity by grouping plants which naturally grow together and are self-sustaining (i.e. self-seeding and spreading without much maintenance) As a result, less fertilizer and pest control is required. Using native, indigenous plants will reduce the need for water. Since native plants may be already accustomed to the climate, they are drought resistant and withstand greater climate variations than non-native plants.

Landscape designs should avoid incorporating allergy-causing plantings and those requiring chemical treatment adjacent to air intakes, entries, or operable windows.

Landscape designs can help reduce energy bills. Placing a windscreen of evergreens on the northwest side of a house will block winter winds. Locating an air conditioner on the north side of the house and shading it with a tree will keep it cool in the summer and reduce energy use. Planting large shade trees on the east and west sides of a house will shade the summer sun and keep a house cooler.
