Water features are not difficult to incorporate as long as important considerations are kept in mind. Two basic styles of water gardens exist, formal and informal. Formal pools have symmetric or geometric shapes and are appropriately used with neatly pruned shrubs and trees, in the middle of a large expanse of lawn, or as a focal point of a garden. The effect created is that of order and clear planning.
Informal pools consist of irregular shapes which are more often associated with nature.
The pool border blends into the surrounding landscape without clear definition. This type looks completely at home in the country or city. The pool form chosen should work with the style of your home and existing gardens. Once the particular style of water garden is chosen, selecting the appropriate size is next. Keep the size of pool in scale with the setting to complement the area.
