Black spots on olearia x macrodonta
This is a young plant overwintered in an 11" pot, (I'm hoping to grow it on a bit until its big enough to take the place of a bit of a privet hedge I'm gradually replacing with shrubs) New leaves are growing well, but last year's have gone very yellow and are covered with black spot like you get on roses. I've removed most of them already, but wondered if its a fungal disease or if last years leaves always do disappear so soon - they were looking pretty miserable before the new growth appeared at all.
