shrub rose

Shrub rose (Rosa 'Radrazz' KNOCK OUT) should be watered deeply and regularly during the growing season which is between spring and summer. Water the plant slowly until the soil has become soaking wet. Allow the soil to dry out between waterings, usually 1-2 inches deep, then begin the process again. This helps to ensure roots are encouraged to grow deeper. Do not water when the soil is already wet, as this will create the potential for root rot. Generally, the shrub rose should be watered twice a week and in periods of drought it should be watered 3 times a week. It is important to water at the base and try to avoid wetting leaves and flowers as this may lead to diseases.

Shrub roses require 6-8 hours of direct sunlight per day for optimal health. The best time of day to provide this exposure is between 10am and 4pm. Remember, the amount of direct sunlight received and the hours of daylight will vary depending on the season. Roses grown in areas where there is direct sun all day may require sun protection in the late afternoon. Rose 'Radrazz' Knock Out does well in bold full sun to part shade and it is important to provide plenty of bright, indirect light if direct sun is not available.

Shrub roses should be pruned annually to keep them healthy and looking their best. Pruning shrub roses begins in early spring after any threat of frost has passed. Start by removing any old, dead, or diseased wood. Then do some light pruning to shape and thin the plant, cutting canes back to about a third of their original length. Remove any canes that are growing in an awkward direction. At this time it is also a good idea to fertilize the shrub. After flowering, it is a good practice to deadhead the spent flowers. Again, lightly prune the shrub to maintain a desirable shape. Late summer is the time to do any heavier pruning, if needed. Remove any dead, diseased, crossing, or weak canes. Again, fertilizing the shrub is important now. Shrub roses do not need to be pruned severely but following these steps can help ensure that your shrub rose is healthy and looking its best.
