- Timing: Prune in early spring before new growth emerges.

Propagation
Propagating the Rosa Pink Knock Out� (Shrub Rose) can be achieved through various methods, including cuttings, layering, and grafting. However, one of the most accessible and successful ways to propagate this rose is through stem cuttings.
Propagation via Stem Cuttings
- Selecting Cuttings: Choose a healthy, disease-free stem from the current season’s growth, ideally with a semi-hardwood (partially mature) texture.
- Preparing the Cutting: Cut a 6-8 inch segment of the stem, making the cut just below a leaf node. Remove the lower leaves to expose the nodes.
- Rooting Medium: Dip the cut end of the stem in rooting hormone and plant it in a well-draining rooting medium, such as a mixture of perlite and peat moss.
- Rooting Environment: Place the cuttings in a warm, humid environment with indirect sunlight, ensuring the medium remains consistently moist.
- Transplanting: Once roots have developed, carefully transplant the rooted cuttings into individual pots or directly into the garden.
