Robellini Palm Frost Damage and Scale: Pruning and Neem Oil Protocol

Frost Damage Assessment

Meebers' 4-trunk Robellini (Apopka, FL) with brown leaves from recent freeze. Also white scale on "branches" (petioles). Previously hosed off and used horticultural oil.

Pruning Guidelines

• Remove only totally dead tissue — brown to green transition
• Preserve all green — still photosynthesizing, feeding palm
• Timing: Now OK for dead tissue; don't rush if more cold expected
• Green near crown = survival indicator

Scale Treatment Upgrade

Dyna-Gro Neem Oil vs. previous horticultural oil:

• Neem: organic, non-washing, builds protection over time
• Horticultural oil: kills everything (good + bad), washes off
• Neem alters taste → pests leave, beneficials stay
• Kathy: only product used at nursery 10+ years

Disease Prevention Context

Neem may protect against lethal palm disease spreading in region (affecting this palm family and native cabbage palms). "Prevention better than none" — no known cure yet.
