A. Rosa `Radrazz' or `Knock Out' rose can be pruned down to 1 to 1 1/2 feet in early spring. This hard pruning helps the shrub remain more compact (3 to 4 feet). When left unpruned, it will grow close to 6 feet. According to the original hybridizer of this rose, `Knock Out' is a vigorous and extremely floriferous rose, with no deadheading required.
