Plus, some water companies in drought-sensitive areas offer a cash rebate for artificial grass. You've got to blow off leaves and other debris, and hose off pet waste. But there's no mowing, seeding, edging, and fertilizing, lawn maintenance chores that take the average homeowner about 150 hours per year.
