When yellowing leaves appear on your pin oaks or mysterious spots spread across your maples, it’s natural to wonder what’s causing the decline. At Gamma Tree Experts, our Board Certified Master Arborist-led team has spent decades diagnosing and treating the specific pests, diseases and soil conditions affecting trees throughout St. Louis. We don’t guess at solutions. We identify the likely cause, then recommend a targeted treatment plan designed to support recovery.

What’s Wrong With My Tree?

You know something isn’t right, but visible symptoms rarely tell the whole story. Local property owners may notice yellowing leaves during the growing season, unusual insect activity, thinning canopies with unexplained branch dieback, and spots or powdery coatings caused by fungal pathogens.

The challenge? These symptoms overlap across dozens of possible causes. Applying the wrong treatment wastes money while the real problem worsens.

Professional Plant Health Assessment in St. Louis

Before we recommend any treatment, we need to know exactly what we’re treating. Our plant health assessment begins with a thorough on-site inspection conducted by ISA-certified arborists. We examine everything from the visible canopy down to root collar conditions, looking for diagnostic clues that reveal the underlying cause.

When visual inspection alone isn’t enough, we conduct soil testing to identify nutrient deficiencies, tissue analysis to reveal what your tree is actually absorbing and disease identification through lab testing. You’ll receive a clear, written diagnosis explaining what’s affecting your trees and an action plan for restoring their vitality.
