Add an unexpected pop of color to an outdoor space with the Orange Glow™ Knock Out® Rose. An abundance of medium-sized double flowers continue to bloom from spring until frost. The inner petals are light orange and gradually fade to a slightly dark orange hue near the outer petals. Hints of pink and yellow emerge near the base of the petals. The flowers are offset by glossy, dark green leaves that have serrated edges.
This rose bush has an upright, branched growth habit. The showy flowers make it a natural focal point, while the full, bushy form makes it a captivating hedge. Plant the Orange Glow™ Knock Out® Rose as a specimen or create a standout flowering hedge or foundation planting. The flowers have a slight fragrance, but it is mild, and this bush is all about the visual appearance, not the scent. Grow the Orange Glow™ Knock Out® Rose in zones 4 through 11.
Orange Glow™ Knock Out® Rose Care
Plant this rose bush in full sun. Give young plants consistent water for the first growing season. Established plants need water during a dry period. Provide loamy, rich soil with a pH of 5.5 to 7.0. The soil must be well-drained. Feed the shrub using a balanced fertilizer or a product intended for roses. Fertilize Knock Out Rose bushes in the spring; after the first round of flowers fade,
Prune the Orange Glow™ Knock Out® Rose in late winter or early spring when new growth appears. Trim the branches back by one-third to encourage new bushy growth. Remove crossed or damaged canes to improve air circulation.
Orange Glow™ Knock Out® Rose Spacing
Mature Orange Glow™ Knock Out® Rose shrubs grow 4-1/2 feet tall and 3 feet wide. Space shrubs at least 3 feet apart when creating a dense hedge. Ensure air can circulate around the branches to keep the plants healthy and thriving.
