Prunus Kanzan (flowering cherry) going brown
I'd really appreciate some advice about why the leaves on my flowering cherry are dropping, going brown and dying off in August.
It's just over a year old. No sign of insects, though I did kill an ant infestation about 2 months ago (with B&Q general bug killer spray).
Soil has been kept watered but the tree looks like it isn't getting enough water (leaves drooping, then drying out and going brown).
I live in Manchester where it's been very wet but soil has not been water logged. We had a week of hot weater and the problem started around that time, but I wouldn't have thought it hot enough to scorch the tree.
Advice much appreciated. Many thanks
