Fungicide for Roses?
I've been hanging out in the Roses forum lately - but the population seems to be more US than Canadian. They've been talking about Bayer Advanced products that aren't available in Canada - nor can they be imported.
I was wondering what I could use on my roses for Black Spot that I can purchase here.
I'm currently using the Green Earth Fungicide. Is this the main product used for this type of problem? Can I spray more often than every 7-10 days? I've been spraying for just over 2 weeks but I don't see much improvement.
Any ideas or help would be greatly appreciated!!
Thanks so much!!
