Shrub Rose 'Radrazz' KNOCK OUT Characteristics
KNOCKOUT are a variety of rose that are relatively disease resistant. The best performance occurs in full sun. Watering should be done at the base of the plant and should soak through to the base of the roots. These shrubs should be exposed to some air circulation to help to fend off fungus and mold. Mulch can help to create consistent moisture and to protect from cold winters. Winter protection over the body of the plant may be required.
KNOCKOUT are relatively disease resistant roses that rarely need treatment for the typical blights that roses experience. Some fungicide treatments may be required if spots appear.
