Pennies may prevent algae build-up in birdbaths

My good friend, garden writer Cindy McNatt, suggested this trick to prevent algae build-up in birdbaths: Place a few pennies in it. Apparently, you need pre-1982 pennies, because later years have very little copper. The pennies are supposed to prevent algae not get rid of it, so start with a sparkling clean birdbath first.

Try it and let me know if it works!

Happy Birding!
