Abstract

Water is the most limiting factor for tree survival and growth. Trees use water during photosynthesis and lose water during transpiration. Water shortages affect both young and old trees. Drought conditions can lead to tree decline, making the tree more susceptible to pest problems. Supplemental watering can greatly assist trees during stressful drought periods in the summer and in the dormant season when soil moisture is limited. Desiccating winds and lack of precipitation can increase transpiration in evergreens (conifers) and create soil moisture deficits even during the winter.
