Q.The leaves on my rose bushes are turning yellow. What is the problem?
One rose bush has many yellow leaves and others have black spots. The yellow leaves are falling off but the black spotted leaves not so much. I have been using an organic fungicide but it looks to be getting worse. What is wrong and what can I do?
