Another thing, not all Taro are pond plants.
Depending on the botanical name of whichever taro you have,
you may or may not have a pond plant.
This is the problem with 'Common Names'.
Colocasias generally like a lot of water.
Alocasias can take a lot of moisture (damp to wet soil), but some species may rot if submerged.
Xanthosoma's are another type of Elephant Ear or Taro,
and they can be finicky about water too...possibly rotting with too much water.
Anyway, maybe someone else will clarify?
I think Marilyn and Tammie know exactly which ones are water sensitive.
HAH! See???!! I knew someone would know...Thanks Lawanna!
