Yellowing leaves can be a symptom of several maladies. Overwatering is the most common, followed by the early stages of disease. Or it could be that the soil pH is out of whack. Roses like a slightly acidic soil. A soil that is too alkaline or deficient in iron may cause general yellowing. If you've ruled out overwatering and diseases, the problem is probably due to soil pH. You can apply Ironite to counteract this problem.
