Troubleshooting Curling Frond Tips on Mature Staghorn Ferns

Two large, established staghorn ferns show curling frond tips—reminiscent of peach leaf curl. Multiple factors could be at play, and a definitive diagnosis requires more information.

Potential Causes

• Drought or salinity stress
• Insect damage (scale, mealybugs)
• Herbicide drift from nearby applications
• Nutritional imbalance

Information Needed

• Photos: whole plant in situ, full frond, close-up of underside (check for white bumps/fuzz)
• Growing conditions: sun exposure, watering frequency, proximity to ocean, fertilization schedule
• Recent changes in environment or care

Disease is less likely. Most causes are treatable once identified. Provide photos or a detailed description for a specific remedy.
