Q.Identify This Tree And How Do We Take A Cutting From It.
We purchased this tree many years ago and it has been re-potted many times. It is beginning to thin out. in the past the greenery was much thicker. We would like to identify the type of tree and ask if there is a way to simply take a cutting to start a new tree.
