Robellini Palm Browning: Root/Crown Rot from Excess Water

One of two Robellini palms turning brown in South Florida suggests root or crown rot from overwatering, especially if the affected plant is in a lower or wetter spot.

Treatment

1. Check soil moisture—reduce watering if soggy.
2. Drench soil with Daconil (chlorothalonil) at 1% solution (1 gal) to suppress fungal pathogens.
3. Inspect base for insects feeding on lower stems.

Prevention

Ensure excellent drainage. Palms hate “wet feet.” Plant on mounds if soil is heavy. Separate irrigation zones if one stays wetter.
