Are you worried your arboreal specimens may need more watering? Recognizing tree drought stress symptoms can help you take action faster.
As the go-to crew for tree services in Holladay, UT, we at Green Pointe Tree Care know a thing or two about keeping living landscapes thriving. Keep reading to learn more.
What Does Holladay’s Environment Mean for Tree Health?
While trees are fairly resilient and self-sufficient, some conditions may necessitate extra care. Specific factors that elevate the risk of drought stress include:
- High evaporative demand: Holladay experiences hot, dry summers that create a high vapor pressure deficit. Trees lose water much faster than their root systems can pull it from the dry soil.
- Soil conditions: The native soils in the Wasatch Front naturally contain highly alkaline conditions, which can impede a tree’s ability to absorb essential nutrients.
- Urban hardscapes: The heat absorbed and reflected by paved driveways, concrete curbs, and buildings increases the temperature of the surrounding soil and accelerates moisture evaporation.
How To Identify Drought-Stressed Trees
If your specimen holds sentimental value, it never hurts to inspect it regularly. Watch out for the following signs of drought stress in trees and take action the moment you notice them.
1. Foliage Changes
Do your trees’ leaves look wilted or droopy? Without enough water, they struggle to maintain the internal pressure needed to keep their leaves firm and upright. They will also roll, cup, or curl their foliage to limit their surface area and reduce exposure to the harsh sun.
When reserves run low, the borders of each leaf may eventually turn crispy and brown from cell death.
2. Canopy Loss
One of the most common symptoms of water-stressed trees is when they shed their leaves outside of Holladay’s autumn season. By dropping leaves, the tree significantly reduces its transpiration rate (the evaporation of water through leaf pores) and reserves remaining moisture for vital structural tissues.
3. Branch Dieback
A tree’s branches eventually die off, starting from the top. This is known as hydraulic failure.
Because of gravity and distance, the uppermost parts of the canopy are the hardest for the plant to push water to. The tree intentionally sacrifices these outer and upper extremities to conserve water for the lower trunk and root system.
4. Bone-Dry Ground
Don’t just look for tree drought stress symptoms because some arboreal varieties are good at hiding their condition. Inspect your specimen’s surroundings as well.
Push a screwdriver six to eight inches deep into the soil under the tree’s canopy. High resistance or a sudden stop usually indicates dry, compacted soil. Low moisture will also cause the ground to develop deep cracks over time.
