Q.Tree planting
I’m in Victoria, Australia. I’ve planted a Schinus molle in a small area over an easement without knowing its growth. Should I remove it?
I'm not familiar with the behavior of this tree in your part of Australia, but I am familiar with its cousin the Brazilian pepper tree, here in Florida. It is a terrible invasive specie, and governments are spending millions of dollars to dig them up, because they are destroying whole ecosystems. If they haven't been declared invasive by your government yet, they probably will be in the near future. I would remove it as soon as possible.
