Ground covers and decorative mulches require less maintenance and water than traditional lawns. Some ground covers may be mowed a couple of times a year to keep them looking tidy. Consider having your yard imitate its natural sourroundings. For instance, if you're trying to landscape in a desert area, forego the green lawn and use sand, rocks, and native plantings to reduce watering and maintenance. Plants and trees that are native or well-adapted to your area will be much less trouble to care for than exotics that require pampering.
Massed plantings are easier to tend than individual specimens scattered here and there.
Be sure to leave plants ample room to grow to full size without continual pruning. Plant trees and shrubs far enough apart to allow unobstructed mowing, and avoid trees that drop lots of pods and twigs. If you have a lot of acreage, plan manicured beds near the house and allow areas farther away to naturalize. Patios and decks with container plantings also are easy to maintain. Once you have your plants in place, practice preventative maintenance.
