Gardening according to location is often called micro-niche gardening. Each location contains many microclimates, or micro niches. Unless you have a flat plain with no trees, buildings, walls or boulders, you will have a variety of microclimates to work with. Micro-niche gardening is a key component of Xeriscape gardening, particularly in the use of water. Hydro-zoning is the grouping of plants together in beds according to their water needs. Garden beds and borders can be planned by grouping plants together according to water, soil, sun, growth potential, temperature and wind protection needs as well. A low maintenance garden is often a garden in which the plants are not only well placed in the landscape, but an indication of the knowledge and expertise of the gardener.
