You don't need a live-in gardener or a fancy irrigation system to make sure your yard gets watered regularly. Instead, you can schedule your lawn or garden watering using a water timer, a handy garden gadget that attaches to your hose bib. These devices work similarly to those light timers you set up indoors before you leave for vacation. Timers start at about $20, but pricier models give you the ability to control the settings via an app on your smartphone. Pictured here, the Orbit Single-Dial Water Timer, available on Amazon; $31.83.
