I received a beautiful rose plant from a close friend but unbeknownst to me they weren't disease-resistant so a few months after having them they developed black spots on the leaves.
Since I kept the roses inside during the winter, I didn't want to use any harsh chemicals to get rid of the fungicide. While researching, I stumbled upon Safer Brand's site and called the company to see which organic product would be best for my roses.
The lady I talked with was super helpful by talking me through how to use the fungicide they would recommend and tips to prevent black spots in the future.
I received the product via mail a few days later and I started to see results in under a week.
For those who want to know, this was the product I purchased: //www.saferbrand.com/store/fungus-disease/5450
