One of the most common tree problems we see in the Treasure Valley isn't caused by pests, disease, or storms. It's caused by irrigation systems that were designed for grass, not trees.
Lawn irrigation systems typically deliver frequent, shallow watering, which is exactly what turf needs. Trees, on the other hand, develop deep, far-reaching root systems when they have to work for water. When a tree is watered the same way as a lawn for years, its roots migrate toward the surface where the moisture is. Surface roots are more vulnerable to drought stress, more likely to heave pavement, and more susceptible to damage from lawn equipment.
There are two common patterns we encounter: overwatering near the trunk (which promotes crown rot and fungal issues at the root collar) and underwatering at the drip line (where feeder roots actually need moisture). Both are invisible problems until they express themselves as visible decline, and by then the damage has been building for seasons.
If your trees have shown signs of stress, bark cracking, yellowing leaves, or declining canopy, the irrigation schedule is one of the first things to review. ArborSafe can evaluate the overall health of your trees and point you toward the right adjustments. Visit arborsafetreeservice.com or call to set up your free consultation.
When you look at your trees right now, do you notice any signs of stress you've been meaning to get a second opinion on?
