Umbrella Tree Leaf Drop: Acclimation, Light, Water, and Pests

Situation

New 5-foot Schefflera (likely S. actinophylla) dropping many leaves after 2-3 weeks. Kept per tag: bright light, allow soil to dry somewhat.

Possible Causes

• Acclimation: Some lower leaf drop is normal.
• Light: Needs a few hours direct sun daily; adapts to less but drops more leaves.
• Watering: Top 2 inches dry before thorough watering.
• Repotting shock: If repotted recently, leaf drop occurs.
• Spider mites: Check leaf undersides for dust-like particles.

Action

Optimize light and watering. Inspect for mites. Photo can aid diagnosis.
