I did see an article today online how to do this carefully.
it was in regards to a Brazilian Pepper, as they are not welcome in the
gardens of Florida, but was brought here, as used as "Holly" in homes.
I was looking at a Florida Universtiy Site for information and may hve been there,
They talked of making sure to get the root ball and dispose of with guidance from the city if in FLorida, as it is considered a major plant pest.
good luck.
