What's eating my bogota kohleria?

Kohleria bogotensis (Bogota kohleria) is a South American gesneriad houseplant. Its soft, hairy leaves and tuberous rhizomes attract mealybugs and spider mites above ground, while fungus gnats target the moist rhizome-rich compost below. Aphids occasionally cluster on new shoots and flower buds. Inspect stems and soil regularly.

Cottony white masses at stem joints, leaf axils, and on rhizomes; sticky honeydew; yellowing foliage Treat above-ground colonies with alcohol swabs and neem oil spray; unpot and inspect rhizomes if reinfestation keeps occurring

Pale, stippled leaves; webbing on underside; plant looks dusty and unhealthy in dry indoor air Increase humidity; rinse hairy foliage gently; apply neem oil or insecticidal soap weekly; avoid overhead watering to prevent fungal spread

Soft green or brown insects on stem tips and flower buds; curled young leaves; sooty mold on honeydew Blast with water; apply insecticidal soap or neem oil; check for ant activity that may be farming aphid colonies

Larvae feed on roots and rhizomes; adult flies emerge from compost; weakened, wilting plant Let compost surface dry between waterings; apply Bti drench; use sticky traps; repot into fresh compost if rhizomes show rot
