More Information

Description The Knock Out® Rose (Rosa) is the original disease resistant rose, cementing its place in horticulture history as a classic! Blooms have a red-pink hue, depending on the light and heat level, and float atop dark green glossy foliage.  Enjoy the flowers on this long-blooming beauty from early summer through frost. Let your rose do all the hard work as it self-cleans spent flowers. No maintenance is required! The disease-resistant series of Knock Out® roses have taken the world by storm. Black spot, powdery mildew, and numerous other typical rose ailments won't touch these roses. Details Botanical name: Rosa 'Radrazz'
Common name: Rose
Zone: 5 - 9
Sun exposure: Sun (> 6 hours sun)
Height x width: 3-4' tall x 3-4' wide
Flower color: Red / pink
Foliage color: Green
Bloom time: Summer-fall
Features: Low flammability, heat tolerant, cold tolerant
Uses: Accent, border, container gardening, cottage gardening, foundation planting, ground cover, hedge, mass planting, ornamental, specimen.
How To Grow Soil: Prefers moist, slightly acidic, well-draining soil. Roses benefit from the addition of compost, aged manure, or leafmold to the planting soil.
Light: Sun (> 6 hours sun)
Water: Try to keep the soil evenly moist, especially in their first growing season. Never allow the foliage to remain wet into the evening; water early in the day.
Spacing: 3 - 4 ft.
Fertilizing: To keep the flowers coming, feed your roses with a fertilizer blended especially for roses. This can be done after each bloom cycle.
Winterizing: Spread a layer of composted manure, compost, or shredded leaves over the base of the plant in late fall after the ground freezes. Covering these mounds and the lower parts of the bushes with evergreen boughs will add protection. Pull the mounding material away from the stem as new growth emerges in spring. Prune injured branches over when new buds emerge in spring.
Maintenance & pruning: Prune to remove deadwood, to control or direct growth, and to promote flowering. Wait until growth breaks in early spring before pruning. Every 2 or 3 years, remove about one-third of the old branches to stimulate new, fresh growth. There is no need to remove faded flowers because these roses are self-cleaning.

Marvelous Heavy Bloomers

Three years ago I purchased three Knockout's and I do mean KNOCKOUTS! They are now a beautiful hedge of red roses. They are easy care and only a little pruning up it a few places. They are really beautiful and blooms all over.
