Hi all, new to the forums. I have searched for 'aphids' and 'black spots' but nothing quite answered my question so here goes... I have a few potted maples along with 2 smaller bonsai. Last week I noticed quite a few had the dreaded aphids showing under the leaves, and my 2 orange dream's were particularly affected. Never had them quite this bad before and a short blast of regular insectiside has always been more than enough. This time around, the aphids have been quickly dispatched, but a week on and most of the leaves on all plants have some kind of black spotting. The orange dreams are again the worst affected and even seem dirty in appearance. A little research and I thought this could be 'sooty mold' but this does not come off, rather it looks like damage or fungi? Just wondering, is this simply the aftermath of the aphid attack? Or something else at work? Some pictures attached/closeup of leaves to help identify. So far the plants still appear healthly with no leaf drop etc. Any help greatly appreciated.
