Knock Out roses are easy to grow, not requiring much care. They are very disease resistant, too, which adds to their appeal. Their bloom cycle is about every five to six weeks. The Knock Out roses are known as “self-cleaning” roses, so there is no real need to deadhead them.
Do knockout roses have to be deadheaded?
All members in The Knock Out® Family of Roses are self-cleaning, so there is no need to deadhead.
When should knockout roses be cut back?
Knock Out Roses can be pruned heavily in late winter or very early spring. This pruning ensures plants will have a good habit and even more healthy blooms throughout the season. This hard pruning can be done while plants are still dormant in later winter or just when you begin to see new leaves begin to emerge.

In late summer to early fall, you can also just cut off the bloom itself. This will result in more stem and leaf growth, which is important for roses heading into a dormant winter period. However, if you do this earlier in the season, the roses will produce more flowers on shorter stems.
