Using a rain barrel can save you a significant amount of money in a season. For each inch of rain that falls on 500 square feet of roof, you can collect 300 gallons of water to use in your garden, or your lawn.
Rainbarrels can be a work of art. Even your kids could decorate them. Cape St. Claire Garden Club is selling them to help raise money for Goshen Farm. Here is the link: http://severnapark.patch.com/announcements/rain-barrels-for-sale-95-fundraiser-30c95e47
