Weeding the pond. I always wanted a pond with frogs and one day when we first moved here we noticed a trickling little bit of creepy goo which turned out to be some ground water. When my husband mentioned digging a small drainage trench I went out and dug a pond instead. The frogs and tadpoles came on their own and we moved some lilies and cattails in. With the little fountain the water remains quite clear and pretty unless we stir it up to weed and the dogs love it.
