Care
Red Shrub Rose Care
Thrives in both full sun and partial shade, with the brightest blooms appearing under full sunlight.
To encourage robust growth, use a balanced, slow-release fertilizer in early spring. Our slow release fertilizer is ideally suited for this purpose.
Pruning, while not necessary, can help shape the plant and encourage more prolific blooming, best performed during the plant's dormant phase.
Regular watering is crucial during the plant's early stages. Once established, the Red Knock Out® Rose shows significant tolerance to drought conditions. Applying mulch is recommended to conserve soil moisture and suppress weeds.
Performs well in a variety of soil types, as long as they are well-draining.
