As we experience this week's intense heat wave, it's not just humans who suffer from the soaring temperatures. Our trees, an essential part of our ecosystem, also feel the strain. As a professional arborist, we want to share some crucial tips on how you can help your trees withstand the heat and ensure their health and longevity.

Understanding the Impact of Heat Waves on Trees

Heat waves can be particularly stressful for trees, especially those that are young or newly planted. Prolonged exposure to high temperatures can lead to:


  1. Dehydration: Trees lose water through their leaves in a process called transpiration. During a heat wave, this process accelerates, causing trees to lose water faster than they can absorb it.

  2. Sunburn: Just like humans, trees can get sunburned. The bark can crack and peel, which opens up the tree to pests and diseases.

  3. Heat Stress: High temperatures can impair a tree's ability to photosynthesize, affecting its growth and overall health.

Tips for Protecting Your Trees

  1. Watering:

  • Deep Watering: Ensure your trees receive a deep watering at least once a week. This encourages roots to grow deeper into the soil, providing better stability and access to moisture.

  • Mulching: Apply a layer of mulch around the base of the tree. Mulch helps retain soil moisture, regulate soil temperature, and reduce weed competition.

  1. Shade Protection:

  • For young or newly planted trees, consider providing temporary shade using shade cloths or strategically placing patio umbrellas.

  • Avoid pruning during a heat wave, as it can expose more of the tree to the sun, increasing the risk of sunburn.

  1. Hydration Boost:

  • Use tree watering bags or slow-release watering systems to ensure your trees get a consistent supply of water without over-saturating the soil.

  1. Monitoring and Maintenance:

  • Regularly check your trees for signs of heat stress, such as wilting leaves, yellowing, or premature leaf drop.

  • Keep an eye out for pests and diseases, as heat-stressed trees are more susceptible to infestations.
