Monstera Deliciosa Deformed Leaves: Light, Water, and Fertilizer Balance

A Monstera owner reports leaves emerging crinkled, failing to unfurl, or breaking mid-leaf. Expert Jonathan initially suspects over-fertilizing causing weak growth, but the owner confirms no fertilizer and minimal water. The diagnosis shifts to insufficient light. The plant needs bright indirect light plus morning/evening sun (avoid harsh midday). In the northern hemisphere winter, full sun is acceptable; in southern hemisphere summer, bright indirect suffices. Once light improves, resume regular watering.

Key Adjustments

• Increase light exposure significantly.
• Water more consistently as growth resumes.
• Clean leaves to unblock pores (leaf shine helps).
• Check for aphids, which target weak growth.
