Where do I get a rain barrel?
You have two options: buy a rain barrel or make one. If you’d like to buy a rain barrel, the “big box” stores such as Lowes or Home Depot carry them. Primex Garden Center in Glenside (link below) carries several different kinds of rain barrels. You may have some success in buying used rain barrels on Craigs List.
If you want to make a rain barrel, be sure to use food grade plastic. Again, you may find one on Craigs List for this. The link below is a resource guide on Rain Gardens. It includes a PHS video on how to make a rain barrel.
