Hi there, I was wonder If anyone could help with an issue I've been having with my potted olive tree. All over the tree are pale brown spots that can be scraped off and they keep spreading to new growth. The spots cover the entire trunk and all older leaves (both on the top and under sides). Is this scale? And if so, is there any way to stop an infestation this widespread (I've tried neem oil without much luck).
Thank you!
