The Red Double Knock Out Rose has quickly become a favorite for gardeners all over the U.S. and beyond. From the same breed that created the original Knock Out Rose, the Double Knock Out packs twice the punch with twice the petals. Traditionally, each medium-sized bloom will range from 18-24 petals. From spring to fall, the Red Double Knock Out Rose produces velvety red double blooms that are deeply reminiscent of classic roses. These gorgeous blooms just keep on popping up for nearly the entire growing season, and they’re perfect for anyone looking for a truly reliable bloomer. Additionally, purplish-green foliage creates an attractive display even without blooms. Furthermore, Knock Outs are self-cleaning, meaning that there’s no need to deadhead them, although you certainly can if you so desire.
Red Double Knock Out Rose Care
These landscape shrub roses are hardy from USDA Zones 5-11. Once established, Red Doubles are generally low maintenance, but will require some seasonal pruning and watering in dry spells. These Knock Outs perform best when planted in full sun to part shade in well drained garden soil. With a mature height of 3-4 feet H x 3-4 feet Wide, this rose won’t engulf your entire garden.
Gardeners that prefer a carefree rose experience will appreciate the Double Knock Out Rose. For example, they’re naturally resistant to black spot, and they feature an impressive winter hardiness. Some gardeners even just trim them back and fertilize them in spring and don’t touch them again until next year. A quality organic or granular rose fertilizer will help them get off on the right foot in spring.
Try them out as a colorful hedge or foundation planting, they’ll keep your landscapes full of blooms almost all growing season long. Conversely, plant them in a garden bed with annuals and perennials as a specimen plant.
