I have 10 roses . They are in front of a stone wall . Every years they get black spot. But then the leaves turn yellow then fall off. The roses look great But the bush has not leaves . Really I have no idea what to do Thanks
Black spot is a fungus that likes moist conditions. When watering the roses avoid wetting the leaves. If you use a hose pipe with a sprayer on the end put it on a jet setting or take the sprayer off and just use the hose.
