Common Ficus Tree Problems: Pests, Leaf Drop, and Diseases

Overview

Ficus trees (genus Ficus) are tropical evergreens prized for glossy leaves and graceful form. Hundreds of species exist, but few are cultivated. Despite their popularity, several issues can arise.

Centipedes in the Soil

Centipedes appear if unsterilized soil was used. To eliminate them, take the plant outside, wash all soil from the roots, clean the pot, and repot in fresh sterile mix.

Leaf Drop from Environmental Change

Sudden temperature or humidity shifts—especially when heating starts in autumn—cause leaf drop. Move the plant to a more stable environment if possible. Ficus thrive on consistency.

Sap Oozing from Sucking Pests

Sap flow often signals mealybugs (cottony clusters) or scale (black/white bumps). Treat with horticultural oil or appropriate fungicide.

Leaf Spot Fungus (Cercospora)

Small dark dots on leaf undersides, yellowing, and leaf drop indicate this fungus. Remove infected leaves, spray with fungicide, and avoid misting afterward.
