Amorphophallus decus-silvae problems — and how to fix them
Amorphophallus decus-silvae (Amorphophallus decus-silvae) 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.
Corm rot
The large corm rots in cold, wet, airless media or if watered during dormancy. Use a deep, gritty, free-draining mix and store the resting corm warm and dryish.
Leaf scorch
Hot direct sun bleaches and crisps the broad lamina. Provide bright filtered light or afternoon shade.
Marginal browning
Low humidity browns the edges of the large leaf. Raise humidity to 60% or more, ideally under glass.
Toppling leaf
The tall single leaf can lean or fall on a loose root system or in wind. Pot firmly in a heavy container and stake if grown in an exposed spot.
