Apartment dweller needs low-maintenance plants for sunny west porch and shaded east porch (wall blocks sun). Previous plants destroyed by white fungus (powdery mildew?) that spread rapidly. Need plant recommendations and safe antifungal treatment.

Diagnosing the Fungus

White powdery coating = powdery mildew. Spreads in humid, crowded conditions with poor air circulation. Spores persist on surfaces.

1. Discard all infected plants and potting soil
2. Scrub containers with 10% bleach solution (1:9 bleach:water)
3. Rinse thoroughly, dry in sun
4. Replace with fresh, sterile potting mix
5. Space containers for air flow

Safe Antifungal Treatments

• Potassium bicarbonate (GreenCure, MilStop) – Organic, preventive
• Neem oil – Organic, fungicide + insecticide
