Inconsistent Soil Moisture

This species requires consistently moist, well-draining soil. Allowing the root ball to dry out completely between waterings causes physiological drought stress, manifesting as crispy brown tips.

Very Common

How to confirm: Insert your finger two inches into the soil; if it feels bone dry, the plant is likely experiencing moisture stress.

Water Quality (Chlorine/Fluoride Sensitivity)

Many tropical plants are sensitive to the chlorine and fluoride levels found in municipal tap water. Over time, these chemicals accumulate in the leaf extremities, causing tip necrosis.

Common
