Saving an Indoor Citrus Tree After Scale Treatment

Dwarf Blood Orange in Crisis Post-Pesticide

Sonja's dwarf blood orange bloomed in December, then developed scale. After hosing off and two insecticide treatments, all leaves dried and branches turned brittle. She's desperate to save this $45 tree and asks when to give up.

Expert Diagnosis: Pesticide Damage Likely

Will Creed suspects the spray caused phytotoxicity. He asks: pesticide name, mixing accuracy, whether sprayed in sun, outdoor temperature during application. He also needs branch flexibility test, watering check method, and photos (wcreed@HorticulturalHelp.com). Citrus are sensitive to oil-based sprays in sun/heat.

Recovery Steps

• Stop all treatments; assess bark for green tissue (scratch test).
• Water only when top inch dry; ensure drainage.
• Provide maximum light (south window).
• Wait 4–6 weeks for signs of new growth before deciding.
