Bayer Advanced All-In-One Rose and Flower Care already offers a fertilizer, insect control and disease control. However, according to the manufacturer, because this product is applied as a drench you are able to apply a fungicide spray around the same time. You would not want to apply the drench and spray at the same time. One product should be applied and allowed to dry before applying the other.
