Gold Dust Croton Blackening Leaves: Sun, Water, or Cold?

Your Codiaeum variegatum 'Gold Dust' crotons turning black and crispy suggests one of three issues—despite moving them to morning sun only.

Likely Causes

Critical Questions

• How often do you water? (Should be ~weekly in summer, less in winter)
• What are night temperatures?
• Do pots have drainage holes?
• Your location/zone?

Immediate Steps

• Check soil moisture deep in pot—soggy bottom = root rot.
• Remove blackened leaves (they won't recover).
• Ensure excellent drainage.
• Provide bright, indirect light (east window ideal).

Crotons need consistent warmth, high humidity, and careful watering. Black leaves usually mean root or cold stress—not sun deficiency.
