Xanthosoma Mafaffa problems — and how to fix them
Xanthosoma Mafaffa (Xanthosoma mafaffa) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Oxalate acridity if undercooked
Eating any part raw or undercooked causes mouth and throat irritation in people and toxicity in pets. Always boil or thoroughly cook corms and leaves before eating, and keep raw material away from animals.
Poor corm development
Thin or dry soil, drought, or insufficient feeding yields small corms. Plant in deep rich soil, keep evenly moist, and feed during active growth.
Leaf scorch in dry heat
Hot dry air and drought crisp the large leaves. Maintain steady soil moisture and provide light afternoon shade in arid, very hot conditions.
Cold damage
Frost blackens foliage and cold soil rots corms. Lift and store corms over winter outside the tropics, or mulch heavily at the warm edge of its range.
