Meyer Lemon Leaf Drop: Overwatering and Root Rot

White fuzzy growth on the soil surface is a fungus feeding on organic matter—a sure sign the soil stays too wet. Meyer lemons dropped leaves and flowers because the roots are rotting from overwatering.

Water only when a finger pressed one inch deep comes out dry. Increase light and air circulation. The plant may recover if caught early, but severe root rot is often fatal. Move it outdoors in spring for the best chance.
