Hi all,
we moved into our place a few years ago and inherited a beautiful mango tree full of fruit. It has been gradually getting this silvery look down the centre of the leaves and now getting worse to a real dark brown, definitely affecting the underside of the leaves worst, and more the older leaves. Unfortunately I don't really know much about it, and after googling you get a million different answers and my tree could have absolutely anything! We got an arborist out who just said nah it's a big healthy tree, it's fine, just fertilise more.
I'm sure it's getting worse and don't want to lose this beautiful tree if I need to treat it or prevent spread, but am at a loss where to look next. Could anyone give me any pointers as to who I could look into or any links that could assist me better? We're in WA so not really tropical, more dry heat.
Thanks so much.
