| Doesn't this springlike weather just make you want to get your hands dirty, as Rebecca Kolls says?
I have a double knockout rose that I'd like to prune to make it more bushy and less gangly. Can I do that now? I'm in Cary. |

| We usually prune when the forsythia is blooming. It is blooming in my area now so I plan to prune my roses soon. Gail |

| I pruned my knock out and other shrub roses back hard this morning. Seemed like the right thing to do, though mine take pruning well any time of year I (or the deer) get around to it. Has anyone seen the new yellow KO, '(Rad)sunny'? |

| Haven't seen it with my own eyes, but our girl Adele out at BB was telling me yesterday that it is really pretty. Can't wait to check it out. |

| I've got a yellow one. I bought it in Delaware last summer. I stopped at a nursery on my way back home. I made a beeline for them. They have a slight fragrance, but nothing to get too worked up over. It starts out really yellow and turns a creamy yellow after a couple days. |

| How far back do you prune them, and I also heard some usually leave 2-3 canes alone. What's your thinking? I have a regular (can't remember name) yellow rose and a knock-out that have several canes about 2-3' right now. |

| I'm probably not the one to advise on how best to prune roses. My strategy was dictated primarily by the fact that we need to get over them with a ladder to clean the gutters this spring. That said, I cut the knock out back from >5 feet to ~3 feet, all canes included, but the oldest ones that were getting woody got pruned back farther to open up the shrub. I don't think I pruned it anywhere near that hard the first year or two, though. |

| I just read you can prune a rose shrub (Tea, etc) when the forsythia is blooming (now) by one-third to one-half down to an outward facing bud. I guess that could go for the knock-outs too. |

| Leaving one or two canes is how you would prune a hybrid tea rose. Knockouts are shrub roses, so do not do that. Take out dead wood and then trim about 1/4 off the top. Here's a great intro video from Paul Zimmerman of Ashdown: http://www.youtube.com/watch?v=7xoof42rrLk&feature=related P.S. yes, mid-March is a good time to prune here. |
