Birds are also great additions to your garden. I know they can have their issues, but I've been looking into ways of attracting birds to naturally control pests.
I tend to try and use what I already have on hand when starting a gardening project. I found this great idea for making your own birdbath using a flower pot drip pan and a hanging plant basket.
I read somewhere that pennies before 1982 contain a bit of copper which helps with algae growth in bird baths. I'm not so sure about that, but I set Daniel out to find some pennies. We put some in and we shall see!
