Hello, I didn't have to do anything to get frogs in my pond. Only one day after it was filled a frog(green) took up house keeping . Now we have two.. Have water they will come.... Maybe you could have some neighborhood boys catch you a few. Give them a quarter or 50 cents each... Next spring you should have tons of tadpoles. Also I say nonsense to the frogs tearing up your plants. Thats a new one to me. FWIW. IMHO. Mike Bernardoni
