Is my tree heat-stressed?

Is my tree heat-stressed?  high temperatures can take you off guard, particularly after cooler days or rainy seasons. Although it is expected that a heat wave can cause weak plants to droop, it can also negatively impact strong and established plants as well as landscape shrubs. While you cannot control the weather, you can take steps to address the rising temperatures by identifying signs of heat stress and understanding how to treat trees that are affected by heat. Now, let’s explore some actions you can take right away to effectively manage unforeseen warm periods, ensuring the survival of your plants and trees during the heat wave.

Water Regularly and properly

Properly irrigate your trees and plants. Adequate watering is crucial, particularly for newly planted trees. Trees require assistance in developing their root system. Ensure that you provide sufficient water to your plants so they can have a reservoir to draw from during the scorching summer months. This becomes even more crucial during extended periods without substantial rainfall—remember to water your trees while tending to your plants and flowers! When it comes to large trees, make sure to water up to the drip line, which extends as far as the tree’s canopy. Additionally, begin watering several feet away from the tree’s trunk. By doing so, you guarantee that the entire root system receives the necessary water for growth and expansion (a tree’s roots do not surround the trunk, so watering there has minimal to no impact).

Mulch

Refresh the mulch over your tree’s root zone. If there is no mulch, a 2- to 3-inch layer can help insulate the roots from heat and minimize moisture loss in the soil. Keep mulch away from the tree trunk as mulch against the bark can lead to fungal problems on your tree.

Keep an eye on your trees and look for these signs of heat stress
