For a long time I tossed care labels in a drawer [to forget] when I re-potted my plants. When my houseplants started to die, I searched for the care labels. I couldn't find any. I had to search the web for help. I spent way too much time searching for identifying my plants and directions on how to care for them so I decided to come up with a better way to store the care labels.
1. Punch a hole in the care label (all I have is a large hole puncher from my classroom!)
2. Once you've punched a hole in all of the care labels, put them on the ring. And now you have all your plants care labels in one place! I hang mine on a hook in my garage.
