Moisture Stress: What Does That Mean for Trees?

Posted by on Sep 5, 2012 in Lawn Care Tips | Comments Off on Moisture Stress: What Does That Mean for Trees?

With below average precipitation over several seasons, trees across Idaho becoming moisture stressed. Trees vary in their ability to tolerate this stress. In fact, native trees have much more tolerance than planted trees and shrubs. Moisture stressed trees are much more susceptible to diseases, insect attacks, and injury by severe weather. What is Moisture Stress? Basically, moisture stress occurs when the amount of water going out of a tree is greater than the amount going in. All plants transpire, loosing water through the foliage. This helps cool the plant and also move water from the roots to the leaves. When there is a shortage of water within the plant, foliage wilts. As this continues, symptoms such as browning of the leaf and needles occur. Deciduous trees and shrubs will drop some or all of their leaves. If a severe shortage occurs over a period of several years the death of the entire plant will occur. What Causes Moisture Stress? Stress from moisture continues to happen over the Winter. Most notably in evergreen trees and shrubs, when water evaporates from leaves and stems when the soil is cold or frozen. Roots extract little moisture from cold soils and none from frozen soils. Furthermore, roots cannot replace moisture lost. Trees and shrubs subjected to winter moisture stress will show browned needles. They might even possibly die over the Winter. This is commonly referred to as Winter death. Moisture stress related to dry soil can be alleviated by proper watering practices. Moisture stress is the primary cause of death for newly planted trees and shrubs, which need supplemental water every 7-10 days if there is not adequate rainfall. For all practical purposes, watering established trees and shrubs in times of drought will usually be restricted to those plants that are within distance of your longest hose. The Solution: It is very important that trees and shrubs receive enough water before the soil freezes. Most of a tree’s roots are located in the top two feet of soil. When watering, you want to soak the soil to a depth of at least 12 inches. Short, frequent watering usually does not penetrate much beyond the sod and organic matter layer of the soil profile. There are several methods of deep watering your trees. The easiest way is to spiral a soaker hose around your trees and shrubs let the hose run slowly for at least four hours.
