How Trees Stay Cool Under the Sun

Can trees recover from heat stress? Let’s talk about why this happens first.

Plants absorb water from the soil through their roots, circulating it to the trunk, branches, and foliage. The moisture eventually evaporates into the surrounding air to stabilize the structure’s internal temperature. We call this process transpiration, and you can think of it as nature’s way of sweating.

Unfortunately, this safety mechanism has its limits. Intense, dry heat puts transpiration into overdrive and quickly causes a tree to lose water. Its overall health suffers when reserves eventually run out.

Is Your Tree Struggling in the Great Falls Heat?  

Can trees recover from heat stress? Before you make hasty decisions, take a moment to diagnose your specimen. Look for the following red flags:

• Wilting leaves
• Dropping stems and branches
• Sparse, yellowing foliage
• Stunted growth
• Rust-colored spots or bumps on leaves
• The trunk oozes sap that attracts insect life
• The surrounding ground has cracks or feels crumbly

Step-by-Step Heat Stress Recovery Plan

If you’re sure your tree has heat stress and not another issue, follow these simple tips:

Deep Watering the Right Way

Help your trees maintain their transpiration cycle during prolonged droughts with supplemental watering. Give it deep, infrequent drinks around once a week, and let the ground fully dry before the next session.

Newly planted saplings need more water because they’re not fully established. Around five to 15 gallons should do the trick.

If you’re looking for a convenient alternative that guarantees consistency, consider installing a soaker or irrigation system.

Mulch Is Your Friend

Mulch protection brings many worthwhile advantages, including:

• Keeping the ground cool under the blazing sun
• Boosting soil moisture retention
• Suppressing the growth of competitive flora
• Creating a more cohesive aesthetic in your garden

You can apply a two- to three-inch layer as far up to the tree’s drip line or the area directly beneath the canopy’s outer edge. Leave a space around the trunk to prevent rotting.

We recommend using organic options like wood chips and shredded bark. As these materials break down over time, they aerate the soil and enrich it with nutrients.

Practice Light Pruning

Trimming diseased or broken branches helps trees recover by directing energy to healthy growth. It also allows air and sunlight to circulate properly throughout the canopy, which reduces the risks of fungal or insect takeover.
