For many people, there is nothing nicer or more relaxing that listening to the sound of running water; whether it is from a babbling brook or water rushing over a weir. There are plenty of ways to imitate nature and introduce water features into a garden.
The most obvious is by having a pond which you can stock with goldfish and which will, in turn, attract other wildlife like frogs, newts, dragon flies and water skaters. There is something lovely about hearing the plop of a frog as it dives through the surface of a pond. If you love the sound of running water then you could construct a small waterfall leading into your pond. As an alternative or as an addition, you could have a small fountain in the middle.
However, if you have a small space or want a water feature to tuck into a corner of your garden or patio then there is a huge variety of cascade water features available to buy in garden centres and department stores. These can come in a variety of designs made from ceramics, metal, stone or glass. Many cascade water features are solar powered and low maintenance with a low voltage pump. From time to time, you will have to top up the water but, apart from that, all you need to do is sit back, relax and listen to the gentle flow of the water.
