Tree and Plant Heat Stress.png

An unexpected heat wave can take a toll on our surroundings, particularly trees, and plants that provide shade, beauty, and ecological benefits. Heat stress in trees is a genuine concern during hot summer months. In this article, we'll explore heat stress, how to identify its signs and the long-term impacts it can have on trees. Additionally, we'll provide valuable tips and strategies to help protect your trees and plants during scorching heat.


If you're experiencing heat stress on your trees, the arborists at Strobert Tree Services are here to assist you in developing an effective plant healthcare strategy for a thriving summer landscape.


What is Heat Stress in Trees?

Heat stress occurs when trees experience prolonged periods of high temperatures, resulting in dehydration and damage to their vital systems. Trees can lose excessive moisture through their leaves and struggle to uptake water from the soil due to increased evaporation rates. This can disrupt their physiological functions and weaken their overall health.


Signs of Heat Stress in Trees


  • Leaf Scorch: Leaves may exhibit browning, yellowing, or wilting, particularly at the edges or between veins. This is a common sign of heat stress, indicating water deficiency in the tree.
  • Leaf Drop: In severe cases, trees may shed leaves prematurely as a survival mechanism. This clearly indicates that the tree is experiencing significant stress and cannot sustain its foliage.
  • Stunted Growth: Heat stress can hinder a tree's growth and development. You may notice reduced shoot extension, smaller leaf size, and limited canopy expansion.
  • Bark Cracking: As the tree's internal tissues shrink due to water loss, the bark may develop cracks or fissures. This weakens the tree's defense mechanisms and makes it more susceptible to pests and diseases.

What Are the Long-Term Impacts?

If heat stress persists or becomes a recurring issue, it can have long-term implications for the health and survival of trees. Trees weakened by heat stress are more vulnerable to pests and diseases, making them prone to further damage. Additionally, prolonged stress can lead to declining tree vitality, increasing the risk of branch failure or tree mortality.


How to Protect Your Trees in Summer


  • Watering: Adequate watering is crucial during heatwaves. Provide deep, slow-watering trees to ensure moisture reaches the root zone. Focus on the tree's dripline, where most absorbing roots are located. Avoid overwatering, as it can lead to root rot.
  • Mulch: Apply a layer of organic mulch around the base of trees, extending out to the drip line. This helps retain soil moisture, regulates soil temperature, and reduces weed competition. Maintain a mulch depth of 2-4 inches, ensuring it does not directly touch the tree trunk.
  • Pruning: Prune dead, damaged, or diseased branches to minimize stress on the tree. Proper pruning promotes better airflow and light penetration, reducing the risk of fungal infections and improving overall tree health.
  • Location: When planting new trees, consider their specific environmental requirements. Select species that are well-adapted to your region's climate and provide them with suitable sun exposure and soil conditions.
