Rubber Tree with Translucent Leaves: Pot Size and Watering Issues

Diagnosing Pale, Translucent Foliage on Ficus elastica

Justyna's two 37-inch rubber trees in a 10-inch pot have light green, slightly translucent leaves and minimal new growth. Younger plants in the same pot thrive. She waters 1 cup weekly and fertilizes monthly with organic fertilizer.

Likely Causes

• Pot too large: 10-inch pot for two mature stems encourages root growth over foliage and risks rot.
• Insufficient water: 1 cup/week won't saturate a 10-inch pot. Water until it drains, then wait until top ¼ of soil is dry.
• Fertilizer details needed: Type and dilution matter; excess salts cause leaf issues.

Recommended Actions

Consider moving to a smaller pot (8-inch) with fresh, well-draining mix. Adjust watering to thorough soak-and-dry cycles. Provide fertilizer details for specific advice. Light (south window in Toronto) is likely adequate.
