Italian Cypress Decline: Mites, Canker, Root Rot

Top-Down Browning and Death in Recent Years

Italian cypress branches brown and die from top down. Any treatment?

Pests: Bagworms, mites (very susceptible, often infested).
Diseases: Root rot in poorly drained soil. Canker has killed many in California.
Culture: Full sun, well-drained soil, water until established. Do not prune.

Check for mites (magnifier). Improve drainage. Canker may be fatal. Many cultivars available ('Stricta', 'Horizontalis').
