Q.no leaves on my roses
Please tell me what fungicide to spray on my roses to get rid of the fungus on them. It has affected my rose garden to where all but 2 out of 8 of my bushes have no leaves on them anymore. My prize bush is over 7 feet tall and after the leaves turned yellow they are all fallen off. Please feel free to email me at firstname.lastname@example.org with any suggestions and answers. Thank you so very much. I hope to hear from you soon. D.. Modglin
It sounds like you have a major attack of black spot or some other funguses as well going on. I would recommend spraying all of your roses with a fungicide called Mancozeb. It is available at Amazon.com. You will likely need to spray your roses down with it 3 to 4 times 5 to 7 days apart to stop a major attack. This product does leave a yellowish powdery residue upon the foliage and canes, that is part of how it works. The black spot markings will not go away but new foliage should be free from it once the fungus has been killed.
