Kingsport, Tennessee, is no stranger to hot, dry summers or droughts. Trees and plants, just like people, rely on water for survival. In a sense, trees are much like humans. For people, our immune system weakens when we lack sufficient sleep or nutrients. Trees are similar. Droughts stress trees and make them more likely to experience disease, fungus, or pests. Today on the blog, our Kingsport arborists share how droughts affect trees and how you can protect your trees this summer.
Droughts increase the risk of pests
Bark beetles are common, and they attack weak trees or trees that are stressed. These tree-destroying insects burrow into the tree’s bark and interrupt its vascular system, which prevents nutrients from being absorbed into the tree. Its effects are similar to trying to drink a beverage through a straw with tiny holes in it. It wouldn’t be very effective! As a result, the tree’s canopy will suffer, begin to dry up, and turn brown.
Droughts diminish leaf production
During dry spells, leaf production diminishes, and leaves are likely to shed before the designated fall defoliation. The tree is attempting to preserve its energy and nutrients by concentrating on the trunk of the tree. This could make your tree look as though it is sick or dying.
Droughts result in smaller leaf size
Trees that aren’t getting enough water may experience a stunt in their growth cycle, including smaller leaf sizes.
How to keep your trees healthy during a drought
During a drought or times when little rain falls, be sure that you protect your trees with these tips.
- Ensure the soil around the tree is moist, not muddy or dry
- Add at least 2” of mulch around the base of your tree to lock in moisture and nutrients
- Avoid digging around your tree
- Avoid pruning live branches
- Don’t fertilize
How to tell if your trees are struggling during a drought
There are telltale signs of drought-stressed trees. Look for yellowing leaves, withering twigs or leaves, brown patches in the canopy, cupping leaves, or shedding leaves when they shouldn’t. If the tree becomes too stressed, it could lead to dead limbs that are subject to falling on surrounding structures or vehicles or pose a threat to bystanders. If your tree is drought-stressed, the best measure to take is to call a professional arborist in Kingsport for a tree health evaluation. Our experts can assess your tree’s health, provide care, and ensure the tree does not pose a falling danger. Sometimes, drought-stressed trees can recover if cared for properly. However, some may not fully recover, and my need to be taken down.
