Top leaves of Pieris fallen off
Hi as you can see from the title this is my problem, the lower part of the plant seems healthy any ideas.
Maybe a photo will help someone answer your query. Welcome to the forum
It's possibly because the soil is too dry but as Fran says, a photo would be a help.
If not, can you give some idea of it's position, sun, shade etc. Also, do you know which variety it is?
