Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

DescriptionThe 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.DetailsBotanical 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 GrowSoil: 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.

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.
