Troubleshooting
Xanthosoma Robustum problems — and how to fix them
Xanthosoma Robustum (Xanthosoma robustum) 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.
Leaf tatter and scorch
Giant thin leaves shred in wind and brown in dry air; shelter the plant and maintain high humidity.
Floppy, weak growth
Too little light or nutrition gives lax stalks and small leaves; give bright light and feed heavily for sturdy growth.
Caudex or root rot
Cold, soggy soil rots the trunk and roots; ensure good drainage and ease off water in cool dormancy.
Spider mites and scale
Dry indoor air invites mites and scale on the broad leaves; inspect undersides, rinse and raise humidity.
