Recently I added some Alocasias to my collection of indoor plants. I got two stingrays and they came in pretty bad shape with root rot. One survived.
Can you snap a leaf off and propagate it in water or do you need to separate out the pups?
What have people found to be the best methods?
Alocasias are growing from bulbs or rhizomes so the best is to use root division or in this case rhizome division.
Effectively this means separating the pups from a mother plant or dividing a large plant into two or more individual plants depending on the structure and size of the rhizomes.
