Water is an essential element in any garden. Not only are plants dependent on it but its soothing sound induces a calm into what can be an otherwise hectic world. Whether it is a small water feature or a large pond, it adds interest and movement to a garden. Natural ponds attract wildlife and an opportunity to grow native water plants whilst formal ponds are conducive to goldfish, Koi and the more exotic tropical plants such as Zantedeschia. Chris Maton and Mark Edwards, both experienced landscape designers, give a clear explanation of the design techniques and site considerations to be made along as well as offering innovative contemporary projects to carry out in your own garden. Clearly illustrated, the ideas are open to personal interpretation whilst offering the backbone of structural considerations. Wall fountains, rills, streams, pebble ponds and raised water features are enhanced by the use of copper, glass, granite and steel. The trend for Japanese gardens is acknowledged with a bamboo cascade and a steel raised rill would fit perfectly in a roof garden or contemporary backyard. Part of the Garden DIY series, this is an excellent addition to its existing range of horticultural subjects. - Lucy Watson
