If your Knockout Roses have grown too tall or have long canes, it’s important To prune them back. Identify The desired height & cut The canes To that point, making clean cuts just above a bud or a healthy outward-facing branch. This will encourage new growth & help maintain a compact & manageable size.

After you have finished pruning, it’s important To clean up any debris & disinfect your tools. Remove all pruned branches & dispose of them properly To prevent The spread of diseases. Clean your pruning shears & loppers with a disinfectant solution To ensure they are free from any pathogens that could harm your roses.

To promote healthy growth & blooming, apply a layer of organic mulch around The base of your Knockout Roses. This will help conserve moisture, suppress weeds, & provide nutrients as it breaks down.
