Hi Sarah — great question and suggestion! I don’t have either a video or article about leggy Knock Outs — however — I’m adding this to my list because it’s a good idea. And I have a leggy Knock Out this year, not kidding. It’s partially leggy because I had removed some branches during the season that were getting too much black spot, and now the rose looks a bit silly. I’m going to wait until early Spring to prune it. What I would suggest is pruning it back by at least a half to two-thirds height, while also pruning out the usual dead stems, crossing branches, and so on that I cover in my “Pruning Knock Out Roses” video. This pruning will encourage the rose to begin pushing out new stems and new growth, which should be much bushier after a hard pruning. You could also coppice the shrub, which is when you prune down to about 18 inches. It’s a more extreme option if you feel like your roses have been leggy for a few years. I hope this helps!

That’s funny Clarence! And I’d add calling them “Knocked Out” when they get overrun with black spot too!

Your comment made me smile Francine! Happy deadheading — and enjoy those roses!

So glad you agree Cassie! It’s a bit of effort but wow does it pay off! Thanks for weighing in!
