Caring for a Mature Ficus Tree (25 Years Old)

Ficus benjamina: The Resilient Heirloom Houseplant

Inherited 25-year-old, 5–6 ft, twin-trunk Ficus in 11" pot, dropping leaves after neglect: standard adjustment response, easily managed.

Basic Care

• Water: When top 1–2" dry. Thorough soak, drain fully.
• Light: Partial shade to full sun (acclimate gradually)
• Fertilizer: 10-10-10 granular 2×/year (spring, summer)
• Repotting: Only if root-bound (roots circling, water runs straight through)

Leaf Drop After Move

Ficus drops leaves when environment changes (light, humidity, temp). Normal. New leaves adapted to new conditions emerge in weeks.

Pruning

• Only for aesthetics (shape, size control)
• Spring best; any time indoors
• Topiary, standard, or natural form all work
• Sap is sticky—protect floors/furniture

Sunroom Considerations

• Unheated sunroom: fine if stays >45°F
• Mist occasionally (spider mite prevention)
• Don't plant in ground—invasive roots destroy foundations/pipes

Adjustment Period

No pruning needed for 3–6 months. Let it stabilize. Leaf drop = temporary. Consistency wins.
