Pond is absolutely fantastic thing in the garden Pauline. It works exactly as you write. It will attract wildlife into your garden. I built my pond almost 20 years ago, putting there just a couple of water plants and fish and was really shocked how quickly it started to live by its own life. There appeared plenty of small aquatic animals, dragonflies, birds, new plants I never planted. Unbelievable. You just have to keep the water healthy, which is sometimes more complicated in very small ones.
