Reviving a Stressed Potted Orange Tree

Reality Check

Citrus rarely fruits well indoors—retail claims of 4 crops/year apply only to outdoor subtropical climates. Indoors, light is too weak and winter temps too warm (citrus prefers 45–60 °F nights).

Current Issues

• Scale: Symptom of underlying stress (light/water).
• Oil spray indoors: Less effective; may suffocate leaves.
• Radiator heat: Caused leaf drop.

Recovery Steps

1. Prune dead/brittle branches.
2. Drench with 5 parts water + 1 part isopropyl alcohol + squirt dish soap.
3. Water only when top soil is dry; avoid overwatering in low winter light.
4. Provide maximum possible sun.

Address the root stressors; the tree may survive but fruiting will remain minimal.
