Why Tree Disease Diagnosis Matters

Tree diseases can spread silently and quickly. What starts as a few discolored leaves or a patch of fungus can escalate into full-blown decay, structural instability, or even death. Early detection is critical. The sooner we identify the issue, the better chance we have to treat it and preserve the tree. Diseased trees also pose safety risks. Weak limbs can fall unexpectedly, and compromised root systems can lead to sudden collapse. In addition, infected trees can spread pathogens to nearby healthy trees, threatening your entire landscape.

Common Signs of Tree Disease

  • Wilting or yellowing leaves
  • Cracked or peeling bark
  • Fungal growth or mushrooms near the base
  • Dead branches or canopy thinning
  • Unusual leaf spots or discoloration
  • Premature leaf drop
  • Insect infestations

If you notice any of these symptoms, don’t wait. Contact Destiny Tree Care for a professional evaluation.

Our Diagnostic Process

We take a scientific and holistic approach to tree health. Our arborists begin with a thorough visual inspection, followed by targeted testing if needed. We examine the tree’s bark, leaves, trunk, root zone, and surrounding soil to identify stress factors, pathogens, and environmental conditions.

Step-by-Step Diagnosis

Our goal is not just to treat the symptoms—but to address the root cause and strengthen the tree’s natural defenses.

Visual Assessment

We inspect the tree for physical symptoms and structural integrity.

Soil & Root Analysis

We evaluate moisture levels, compaction, and nutrient deficiencies.

Pest & Fungal Identification

We look for signs of insects, mold, mildew, and rot.

Lab Testing (if needed)

For complex cases, we send samples to a lab for precise identification.

Treatment Plan

We create a customized strategy to restore health and prevent recurrence.

Common Tree Diseases We Treat

Our team is trained to recognize and treat a wide range of tree diseases common to Northern California. These include

Root Rot

Caused by overwatering or poor drainage, root rot weakens the tree’s foundation and can lead to sudden collapse.

Powdery Mildew

A fungal infection that appears as white powder on leaves, reducing photosynthesis and weakening the tree.

Oak Wilt

A deadly vascular disease that affects oak trees, causing leaf discoloration and rapid decline.

Aphid Infestation

These tiny pests suck sap from leaves and stems, leading to curling, yellowing, and stunted growth.

Bark Beetles

These invasive insects bore into the trunk, disrupting nutrient flow and causing dieback.

Leaf Spot

Caused by fungi or bacteria, leaf spot creates dark lesions and premature leaf drop.
