Italian Cypress Decline: When to Call a Certified Arborist

Diagnosing Dieback in Italian Cypress

An Italian cypress showing progressive branch death from the ground up—especially after drought followed by heavy rain—could be suffering from root rot, canker, spider mites, or other stressors. Since only one of three trees is affected, site-specific factors (drainage, irrigation, soil compaction) are likely involved.

Why a Certified Arborist Is Essential

• Accurate diagnosis requires on-site inspection, possibly soil/tissue sampling.
• ISA Certified Arborists have specialized training in tree pathology and risk assessment.
• Many offer free initial consultations.
• Search "ISA certified arborist + your city" or check TreesAreGood.org.

Avoid generic "tree trimmers"—they lack diagnostic credentials. A proper evaluation can save the tree or prevent spread to its neighbors.
