I have had an Anthurium for several years, growing in an Atrium. There is humidity and plenty of light. It has never been without blooms and grew into a tall plant with two main stems and several small plants at the bases. I watered the plant a few days ago and must not have had the plant staked very well, because one plant stem broke off yesterday at soil level, and has only one root still attached and still sticking in the original pot/soil. I want to know, if I can plant the broken off section separately, in a new pot with a small part of the stem and air(?)roots buried in the soil. I keep reading, when replanting an Anthurium, to plant the same depth as originally...(which I can't, as I said it broke off right at soil level) The first picture shows the plant a year ago, the last picture was taken today, late evening, but you can see the little "air" (?)roots I am referring to.
I believe it is highly likely that the branch will become its own plant! Place it in its own pot and care for it as you would the original. You will have another plant in no time!
