Trees, undoubtedly, are the most valuable plant in a landscape and must be prioritized for irrigation in drought conditions. Grass easily recovers from a period of long drought; hence, it must be placed last on the priority list for irrigation. Many resources are available online that explain ways to irrigate landscape trees. However, growers and homeowners in Utah are still confused about quantifying and applying the appropriate amount of water a landscape tree needs. This Excel spreadsheet is an irrigation calculator designed to determine the amount of water a landscape tree needs in Utah’s hot and dry summer months. Find instructions for determining calculator inputs in the correlating fact sheet, "How Much Water Do Landscape Trees Require in Utah? An Irrigation Calculator" by Shital Poudyal.
