Planting and growing
Rainbow Knock Out® Rose will grow to be about 4 feet tall at maturity, with a spread of 4 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 20 years.
This shrub should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid.

"The first wave of flowers will be abundant. Then the roses will typically have scattered blooms until another wave of heavy flowering occurs. This will repeat until the first hard frost." - The Knock Out® Family of Roses FAQ
Care
Water your Knock Out® rose generously until it is well established. We also recommend watering established plants periodically during droughts. Deadheading is not needed for continual flowering. Fertilizers are not necessary but can be applied, if desired, to increase floral display. Any fertilizer tailored for roses and/or shrubs, followed according to the label, will do.
Knock Out® roses are "shrub roses" and are much more pest and disease resistant than Hybrid-tea and Grandiflora roses. That said, any issue can be remedied by general products from the garden center.
Heavy pruning, if desired, is best reserved for late winter or early spring right before or when new growth begins to emerge. When pruning we recommend taking no more than 1/2 off the established plant. Avoid pruning during heat waves, droughts, and anytime during fall.
Note: Despite having prickles (thorns), roses are NOT deer resistant. Please plant accordingly.
