COMMON TREE ISSUES WE TREAT IN EAST VALLEY
Fungal Infections & Rot
Our dry Arizona climate still poses threats like sooty mold, root rot, and powdery mildew. We identify the fungus, remove infected branches or roots, and apply effective treatments.
Insect Infestations
From borers and aphids to scale and whiteflies, pest infestations can go unnoticed until it’s too late. We inspect and treat trees with eco-conscious solutions that eliminate pests and prevent reinfestation.
Nutrient Deficiencies
Iron chlorosis and nitrogen deficiencies are common in desert soils. We provide deep root feeding and soil amendments to restore your tree’s health and color.
Bacterial & Viral Diseases
Leaf spot, wilt, and cankers can destroy trees from the inside out. Our team provides targeted pruning and treatment to halt the spread and support regrowth.
WHY PROMPT TREE DIAGNOSIS MATTERS
Tree issues worsen over time and can spread to nearby plants. Early detection is key to avoiding the need for complete removal. Jose Knows Trees uses a trained eye and expert techniques to catch symptoms early, provide cost-effective treatments, and offer practical maintenance advice to prevent future problems.
We believe in transparency, so we’ll always explain your options, what caused the issue, and how to best treat and monitor it.
