Bugs and Disease
Rose chafers and green slugs are really chewing up my roses. Any special favourite recipes out there for a spray that is "organic"?
Also, I have another problem. Powdery mildew appeared on a container rose I bought this spring and it is spreading to nearby roses. The rose it appeared on is supposed to be resistant to mildew. Does anyone have a suggestion for this?
I might be naive but I was hoping that I wouldn't have to spray. I didn't last year but everything is getting hit hard and early this year.
Its been cool and rainy here in Ontario so far this spring with only a few really hot days.
