Jasmine Tree Defoliation: Humidity Shock and Overwatering

4-foot "jasmine tree" (bought August) lost all leaves; Miracle-Gro sticks didn't help. Indoors for Montreal winter. Owner never grew jasmine.

Expert Analysis

• ID needed: Many jasmines (J. sambac, Maid of Orleans, etc.); some fragrance-free, various colors/habits. Check label.
• "Tree" form? Jasmines are vines—may be trained or mislabeled (e.g., night-blooming jasmine).
• Miracle-Gro wrong: Fertilizer doesn't fix leaf drop; drop = plant in trouble.
• Cause 1: Humidity shock—greenhouse (high humidity) → home (low humidity).
• Cause 2: Root rot from overwatering (common with new plants).
• Bloom temp: True jasmines bloom in 50s°F; day length + temp trigger buds.
• Fertilizer timing: Only when bud-set begins.

Rescue requires ID, less water, cool temps, patience.
