What is a water stressed plant?
Plants experience water stress either when the water supply to their roots becomes limiting, or when the transpiration rate becomes intense. Water stress is primarily caused by a water deficit, such as a drought or high soil salinity.
What happens when the plant gets water stressed?
The first signs of water stress in landscape plants and trees include wilted or drooping leaves that do not return to normal once temperatures cool at night, curled or yellow leaves that may fold or drop, leaves that change to a grayish or bluish green color, sunburned leaves and new leaves that are smaller than normal …

How do you water stress a plant?
Water stress treatments are made by reducing a soils moisture content and by maintaining the moisture content at this new low level for a period of time. Changes in soil moisture are achieved by reducing or increasing a soils moisture content to levels close to or way below its field capacity (water holding capacity).
