Overwatering Causes Black Tip Rot in Pachypodium (Madagascar Palm)

A 2-foot Pachypodium lamerei in 6-inch clay pot developed blackish-purple growth tip, leaves, and midrib discoloration with leaf drop. Black trunk skin peels off, revealing green sap. Roots appear healthy.

Diagnosis

Blackening indicates overwatering. The saucer likely holds water too long. Container succulents need saucers emptied within 15 minutes. Newly potted plants should be watered at the rim initially, as center soil retains moisture.

Correction

Empty saucer promptly. Allow soil to dry completely between waterings. The green sap under black tissue suggests the main stem may recover if rot hasn't penetrated deeply.
