Eco-Friendly Outdoor Patio: Gutters on this Longwood, Florida, home direct runoff into a rain barrel. A hose connected to the rain barrel makes it easy to hand-water a few pots nearby. A rain chain also guides water from the roof into a large pot. (Photo: Ralph Anderson)
Reuse rainwater with these barrels made from trash cans. Placed underneath your home's downspout, a rain barrel can help conserve water (and money) by capturing rain runoff from the roof. You can then use that water for the garden. You'll find a variety of barrels available online: Look for ones that have a spigot for a house attachment. Or make your own from large plastic trash containers. You can purchase a pump to help deliver the water through your hose, or a tap to fill your watering can.
