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
