Further to fulfill the nutrient requirements, you may need to fertilize your rose plant using nitrogen-rich fertilizer.

In addition to that, develop the habit of watering your plant early in the morning, avoiding overhead watering. If necessary you can also go for a dedicated fungicide.
Spider mites are very small insects that draw crucial fluids or sap from the undersides of rose bushes, spinning delicate webs. Once infested, the leaves are found to turn yellow, eventually fading off completely.
