I was always taught that a sucker is a shoot coming from the rootstock.
Just because you have a shoot coming from the base of a plant, that isn't
grafted, and shoot is coming from above ground level, well that would be a
shoot wouldn't it?
Just trying to clarify it in a discussion I had with someone.
They claim that a shoot coming from the base of a maple (not grafted), is a
sucker and it means the tree must be diseased.
Any comments?
Also, link to a website explaining this would be great.
