Brown Spots on alocasia frydek
What's Happening
Brown spots on Frydek are usually fungal (Cercospora) from standing water on leaves, spider mite stippling, or edema (burst cells from overwatering). Phosphorus deficiency can also manifest as purplish or brown speckling.
How to Fix It
- 1
Inspect leaf undersides for spider mites and treat with alcohol/soap if detected
- 2
Apply a copper-based fungicide if spots have yellow halos and are spreading
- 3
Improve ventilation with a fan to ensure leaves dry quickly after watering
- 4
Switch to bottom-watering to prevent moisture from sitting on the velvet foliage
- 5
Supplement with silica to strengthen cell walls against pathogens and pests
How to Prevent It
Ensure 60-80% humidity without direct leaf misting. Maintain bright indirect light to support nutrient uptake. Use a sterile, chunky potting mix.
