How to control black spot on roses
Plant black spot resistant roses, as many beautiful rose varieties are resistant to the diseases and fungi.
Control black spot by not planting varieties that are prone to it. Maintenance of the resistant varieties is much less than those that fall victim to every rose disease.
Specific lists of disease-resistant roses are online, and nurseries likely have their own list. All roses vary by region, so do a local check for varieties that grow best in your area.
