Greetings, I've planted this Eonymus Japonicus Marieke last year in October. It looked ok until two months ago when the leaves have started displaying this brown edge. No foliage loss, no pests as far as I can tell. There is new growth, but also displays the same brown edges here and there.
I fed it in the last 2 weeks and mixed the soil with compost. Anything else you would recommend?
