Queen Palm Loses Center Frond: Caterpillars or Crown Rot?

Center Frond Pulling Out Is a Dire Sign

A year-old queen palm lost its new center frond, which pulled out easily. Black caterpillars and eggs/frass were found inside.

Primary Concern

Nick says the caterpillars are secondary. The center frond pulling out typically indicates fatal crown rot, even if older fronds look green. He urges contacting a local extension agent for a master gardener inspection.

Action

Don't rely on insecticide alone. Have a professional assess the crown. If rot is confirmed, the palm cannot be saved.
