|Wilting can be a symptom of overwatering or soil that doesn't drain well - unless you see some signs of fungal infection. Downey mildew comes to mind: Previously vigorous leaves wilt, turn yellow and fall off the plant. The young shoots also wilt and die back. It can also affect the calyxes of the bud and cause the bud to look distorted. Blackish or dark red/burgundy stains are seen on the infected upper surface of leaves and stems. These sometimes resemble the strokes of a paintbrush. Sometimes there is a downy fungus on the undersides of the leaves. Downey Mildew usually occurs when the humidity gets high (over 85%) and the temperature is below 75 degrees F. If this sounds like what your rose bush has, prune away the affected plant parts and spray with a fungicide. Best wishes with your roses!
