The Knock-Out roses prefer well-draining, slightly acidic soils. These shrubs are naturally bushy and compact, but you can prune them to fit into smaller spaces around your landscape.

If you want to maintain the size and shape of the shrub, a light pruning should be done in the early spring or late winter when it is dormant. By pruning on this schedule, you can keep the plant healthy and encourage it to grow in the spring. Deadheading is unnecessary for the rose, but it will help the shrub to reflower in the following growing season.

After pruning, the rose bush should be fed with a balanced fertilizer. However, the rose bushes will benefit from regular feedings throughout the growing season. You will want to stop fertilizing after the first hard frost. Fertilizing should also not be done immediately after planting since you want it to have a complete bloom cycle.

Watering is very important to any plant, especially the Knock-Out rose. You want to water this plant regularly during the first growing system. With added water, the roses develop a sound root system. After the roots have been established, you should water once every week or two. These plants thrive when watered deeply in the morning. While these roses are drought-tolerant, you might want to add a layer of mulch to retain moisture throughout the growing season.
