Pecan trees extract the moisture they need from soil in the root zone daily during the growing season. The amount a tree withdraws may vary from a gallon or less for a young tree to as much as 150-250 gallons per day in a fully mature tree. This water demand is the tree's peak (maximum) water use on the hottest day of the summer. Water consumption is decreased before and after this maximum use.
