BLOG The Impact of Humidity on Tree Health: Expert Insights and Solutions by Anstaetts Mar 14, 2025

Understanding how humidity affects tree health is crucial for any property owner looking to maintain a robust and beautiful landscape. At Anstaetts Tree Service, we've seen the challenges that varying humidity levels can present to trees, and we're here to share expert insights and solutions.

Humidity, the amount of moisture in the air, plays a significant role in the overall health of trees. It's one of those environmental factors that often goes unnoticed but can have profound effects on trees. High humidity can promote the growth of fungi and other pathogens, leading to diseases that can weaken or even kill trees. On the other hand, low humidity can cause stress by increasing the evaporation rate, which can dry out a tree's foliage and inhibit its ability to photosynthesize effectively.

In regions with high humidity, trees are at risk of various fungal infections. Fungi thrive in moist environments, and when combined with warm temperatures, they can spread rapidly. You'll often notice symptoms such as discolored leaves, cankers, or unusual growths on the tree's bark. Addressing these issues promptly is vital. Regular inspections and maintenance, like pruning infected or damaged branches, can help manage these risks.

Moreover, dense canopies in humid areas can trap moisture, creating a microenvironment that is even more conducive to disease. Thinning out the canopy by pruning can improve air circulation and reduce the likelihood of fungal infections. Anstaetts Tree Service recommends scheduling regular health checks, especially during peak humidity seasons, to ensure that any potential issues are caught early.

Conversely, low humidity poses its own set of challenges. Trees in dry areas may struggle to retain moisture, leading to issues like leaf scorch or dieback. In such conditions, supplemental watering becomes crucial. However, it's important to water trees deeply and infrequently, encouraging roots to grow deeper into the soil which increases their access to moisture. Mulching is another effective technique, which helps retain soil moisture and provides temperature regulation around the tree's base.

Anstaetts Tree Service understands that each tree species has different tolerance levels to humidity. Native and well-adapted trees are usually more resilient to the climate fluctuations, whereas exotic species might require more intensive care. Thus, selecting the right trees for your landscape according to your local climate can prevent many humidity-related problems.
