As in agriculture, amenity landscapes that have ornamental or utility value are irrigated when rain is insufficient to support expected growth. Irrigation to compensate for inadequate rainfall can be permanent in arid areas or temporary with short-term drought in high-summer-rainfall areas. Landscapes have additional irrigation requirements uncommon in agriculture. Most landscape plants need short-term irrigation following planting until they establish new roots in the surrounding soil. Finally, plants can be placed in landscape situations of very limited soil-water availability, such as above-ground planters, that require permanent irrigation regardless of the climate.
