Troubleshooting a Struggling Rubber Tree (Ficus elastica): Humidity, Watering, and Fertilizer Mistakes

Single Stem Is Normal

Rubber Trees naturally grow a single trunk in pots. Lower leaves drop as new ones form at the top—this is typical, not a problem.

Leaf Curl Causes

• Low humidity (central heating dries air).
• Overwatering (roots rot, can’t uptake water).
• Cold temperatures (leaves curl to conserve heat).
• Over-fertilizing (salt buildup burns roots).

Corrective Actions

• Stop fertilizing (or use only a few times per year).
• Use cheap, simple potting soil—no Miracle-Gro with continuous feed.
• Water only when soil is dry (check by weight or finger).
• Bright, sunny room is fine—just avoid leaf scorch.
• Increase humidity if air is very dry.

Philosophy

“Plant it, leave it alone, check occasionally.” Over-care kills more Rubber Trees than neglect.
