tree branch in my pond
can anyone help
I would like to encourage frogs and toads into my pond. I have had a pond for about 2 years but never seen a frog or toad anywhere near the pond. The pond is a preformed fibreglass one with very smooth sides so i can only assume that frogs cannot get in or most importantly get out so my question is can i put a tree branch or a large log in the pond to help them in and out of the water or will it rot and contaminate the water?
