Sago Palm Defoliation by Landscapers: Scale or Shock?

All Fronds Removed from 20-Year Sago: Will It Recover?

Landscaper removed every frond from mature sago (Cycas revoluta), claiming disease. Nursery says it'll regrow. Recovery is likely IF the cause was scale, not disease.

Why Total Defoliation Happens

• Aulacaspis scale infestation: Heavy coating warrants complete removal to eliminate pest reservoir
• Disease (rare): Fungal crown rot would show trunk symptoms, not just fronds

Critical: Scale Persists After Defoliation

Scale insects survive on trunk, roots, soil. New fronds will be immediately reinfested without treatment.

Mandatory Treatment Protocol

1. Monitor new growth daily as it emerges
2. At first sign of white dust (scale crawlers): horticultural oil spray (late afternoon)
3. Systemic drench (imidacloprid) when growth active
4. Repeat oil every 2 weeks through establishment

If True Disease

Symptoms: oozing trunk, fungal conks, soft caudex. Different treatment needed. Photos help diagnose.

Florida Context

Scale epidemic last 3+ years. Most defoliations are scale-related. Proactive treatment saves the plant.
