Xanthosoma Sagittifolium problems — and how to fix them
Xanthosoma Sagittifolium (Xanthosoma sagittifolium) 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.
Confused with taro for water needs
Overwatering to bog conditions rots tannia corms — keep it moist but well drained, unlike Colocasia.
Leaf scorch and tatter
Large thin leaves brown and tear at edges in dry air, wind or drought; provide humidity, shelter and steady moisture.
Small or forked corms
Compacted or shallow soil and a short season produce poor corms; plant in deep, loose, fertile ground for a long warm period.
Corm rot during storage
Lifted corms rot if stored damp or chilled; cure and store dry and frost-free over winter.
