Persistent Brown Spots and Sticky Residue on Bird of Paradise

Complex Issue: Bacterial Disease and Irritating Sap

Jen's Bird of Paradise has brown spots, sticky sap that irritates skin, and the problem has spread to other plants. Alcohol, soap, and wiping haven't worked. The plant hasn't flowered in four years.

Expert Advice

This sounds like a bacterial disease, possibly Cercospora, which is difficult to control without lab confirmation. The sticky substance causing skin irritation is unusual and concerning.

1. Take a sample to your local Cooperative Extension Service for accurate diagnosis.
2. Isolate the affected plant to prevent spread.
3. Follow the extension officer's treatment recommendations precisely.
4. Flowering requires maturity, high light, and proper nutrition; address the disease first.

Do not attempt further home remedies without professional identification.
