Get over a barrel

In the gardener’s dictionary, harvesting usually follows sowing. But more gardeners are harvesting before planting a single seed. The harvest is rainwater and the container is a rain barrel.
Harvesting rainwater is an old technique that is undergoing a renaissance. The green movement, sensitivity to climate change and the growing cost of municipal water have convinced mnay homeowners it’s better to gather water that falls from the sky instead of turning on a tap.
“It’s becoming popular for a lot of reasons. People are seeing it for the ancient resource that it is,” says Richard Harris, owner of Cape Fear Green Solutions, Inc. in Wilmington, N.C.
Harris says an inch of rain falling on a 1,000-square-foot roof can yield 620 gallons of water. The water collected from a 2,000-square-foot roof would be sufficient for landscape irrigation and other utility uses.
Municipal water restrictions and the higher cost of water is good for Steve Vesper’s business. The operations manager for Clean Air Gardening, says his Dallas company sells more ran barrels than it did a few years ago. The barrels range from 30 to 300 gallons or larger. A 55-gallon kit, one of the most common sizes, costs $100. But many organizations and governmental agencies are offering DIY workshops for less; usually the cost includes materials for the barrel. Whether you buy a barrel or build your own, keep these tips in mind:
Get the right type of container. A makeshift rain barrel can be dangerous, and also can attract mosquitoes and other pests. “You don’t want to get a trash can and put it underneath the down spout,” Vesper says.
Get the right barrel size. Are you watering the landscape or a small plot? Plan and purchase accordingly.
Pick the right location. A gallon of water weighs about 8 pounds. A full barrel is difficult to move.
Raise the container so the water can flow easier. Unlike water pipes, rain barrels aren’t pressurized. Gravity pushes the water through a hose. Set the rain barrel on a sturdy pedestal about 18 inches high or install a pump.
Seal and cover the container and use the water. A sealed container and flowing water prevent the barrel from being an incubator for mosquito larvae. The seal doesn’t have to be elaborate; a piece of wire mesh from a screen door will work.
