Novice gardener here
hoping for some wisdom about my poor camellia.
I've been searching images online and there seem to be so many causes of yellowing leaves / black spot from fungus to overwatering too wrong soil PH.
Here are some pics ... I think the camellia has been there about 5-8 years. It is planted near a fence that runs N-S and under a mid sized prunus. Our soil is clay and I noticed the yellowing more after the cold weather / snow in March / April but I think it was there last year and I didn't really think anything of it. I gave it some slow release ericacious fertiliser (the little balls) about 6 weeks ago, could that be it?
Is it ok? What should I do?
Thank you
