What is this growth on my acer?
Could anyone help identify the problem with my acer (see photo), and suggest how I might treat it? Currently the problem seems to be centred on the base of the trunk, and the rest of the plant seems healthy; however, I am afraid that this will soon not be the case. I have had the acer for just over two years, and have only recently noticed the problem. Any advice will be much appreciated.
