The Effects of Drought on Your Trees

The Effects of Drought on Your Trees




Drought can affect your trees in many different ways. The longer the drought, the more harsh the effects on your trees. The effects of drought are considered short-term or long-term, and your trees are more likely to retrieve from short-term effects.

Short-Term Effects

– permanent Wilting. As the amount of moisture obtainable in the soil decreases, the leaves on the tree dry out and begin to wilt. The amount of visible tree leaf wilting varies by tree species in addition as the amount of soil moisture obtainable. permanent leaf wilting is usually resolved at night when the leaves are re-hydrated with dew and retrieve until the next day.

– Leaf Shedding and Coloration. Premature shedding of tree leaves and leaf coloration can be brought on by periods of drought. In many species, leaf mottling or uncompletely browning occurs during droughts. It is quite shared for yellow poplar trees to discarded leaves during summer droughts, in addition as sycamore and buckeye trees. Dogwood leaves wilt and die, instead of being discarded during droughts. Summer droughts often cause early autumn leaf coloration, and the needles of conifers may turn yellow and brown.

– Growth Inhibition. Periods of drought decline the seasonal growth possible of your trees. Drought affects the development of the tree shoots, the width of the annual growth ring in the tree trunk, and the root system. The young roots, which are the major water-absorbers, are the most easily damaged by drought.

Long Term Effects

– Signs of Die Back and Decline. If there is not enough moisture in the soil for an extended period, the roots cannot supply the crown of the tree with enough nutrients and moisture. The consequence is the crown beginning to die back in order to bring the tree and the root system into a better balance. Leaves, twigs and branches will begin to die, especially in the uppermost areas of the tree.

– Pest Problems. As trees’ health decline from long-term drought, they become predisposed to pest attack and infestation. Many pests are unable to survive in healthy trees. However when trees have been deprived of moisture and nutrients for a lengthy period, their response to pest attack is weakened and they have poorer recovery from pest damage.

– Wounds and Disease. Long-term drought weakens the tree’s ability to retrieve from minor wounds, and increases the chances of tree diseases. When a tree is unable to compartmentalize or isolate a small wound, pathogens freely move into and habited, causing increasing damage. Stem canker disease is a shared effect of long drought periods.

Taking time to water your trees can counteract the unhealthy effects of drought. If your trees have enough soil moisture, they will keep healthier.
