This is a geranium planted recently however every leaf has holes and brown spots like rust. I can't see any insects on any of the leaves. Can anyone give me some advice as to the cause and what to do with it? Thanks
Thanks for info. Certainly looks like the pictures of sawfly when I went to link although nothing to see. It is a in a very sunny position so think I may lift and put into a pot and see how it goes. It isn't variety I've had before and have geraniums in a similar sunny position but it's first blue one so don't want to lose it.
