Home > Question >

Is there an organic way to control blackspot and mildew on roses?


Our Advice:

Try using Uncle Tom's Rose Tonic, which contains potassium phosphite. It is referred to as a nature-identical plant food which promotes healthier growth and tougher leaves. Start spraying when the leaves begin to develop, as the aim is to get a protective layer over the leaves before the diseases become established.
