Italian Cypress Dead Zone: Spider Mites Likely

Row of 15 Italian cypress, 12 ft tall. End tree has recurring dead zone on east side (ground to 3 ft). Sprayed for "spiders" 2 years ago helped; recent spray failed.

Diagnosis: Spider Mites

• Test: tap branch over white paper; red moving dust = mites.
• Mites thrive in hot, dry, dusty conditions.

Control

• Insecticidal soap or miticide from local nursery.
• Regular monitoring; repeat as needed.
• Improve air circulation; avoid dust buildup.

Targeted miticide more effective than general insecticide.
