Burnt edges on rose leaves
I'm having problems with my rose for a while now.
I've tried spraying it with various types of anti-disease and anti-bacteria; I've tried moving it out of the sun to a shadier and cooler location.
Things are not getting any better.
The edges of the leaves are "burnt", some of them change colour and die...
Also, there are some sort of mushrooms growing now (a new development).
