Knock Out Roses
Easy-care, cold-hardy, disease-resistant, proficient-blooming and knockout gorgeous, it’s easy to understand how Knockout Roses became the most popular rose variety in just over a decade.
Knockout rose varieties produce a new explosion of colorful blooms every 6 weeks from spring until the first hard frost of fall. With a wide range of bloom colors to select from and flower petals that are either double or single, it’s easy to find Knockouts that will fit perfectly into your landscape theme.
Adaptable Knockout rose bushes can even be grown in containers to beautify patios and porches. Nature Hills also carries the very popular knock out roses in tree form. It’s essentially an outstanding variety of shrub rose trained into tree form…and with exquisite results!
Knockout roses are easy to grow & hardy in zones 5-9, and will reach a mature size of 4 feet tall and wide. The rose bushes are naturally compact and bushy, but can be pruned to fit into smaller spaces. Prune when bush is dormant during the late winter or early spring, feeding with a balanced rose fertilizer immediately after pruning.
For the best show of continuous rose blooms, Knockout roses need to be fed with a specially formulated rose food immediately after each bloom cycle. To make up for the frequent bush feedings, the spent rose blooms don’t have to be removed from the bush, Knockouts deadhead themselves.
