The Q&A Archives: Rose Leaf Problems

Question: I planted a rose this spring and it did very well in the beginning. It had blooms in June and then stopped flowering. Now the leaves seem to be infected. They are whitish, look like frost and are wilting. HELP!

Answer: Sounds as though your rose has a full-blown case of powdery mildew, a fungal disease that commonly attacks roses. If your plant stopped blooming early in the season, I suspect it's not getting the all day sunshine it needs to flourish. Roses prefer 8-hours of direct sunshine each day, well-draining soil, and good air circulation all around. Given these conditions your rose bush should thrive. Prune out all of the infected leaves and stems to prevent the spread of powdery mildew, and to help open the plant up to better air circulation. Some plants are more susceptible to fungal diseases than others; try to watch for signs of powdery mildew and pick the leaves off before the disease can spread to other, healthy plant tissues.
