How to grow knockout roses from cuttings?

Growing Knock Out roses from cuttings is quite straightforward! I've propagated dozens this way:

Take semi-hardwood cuttings in late spring or early fall from healthy, non-flowering stems. Each cutting should be 6-8 inches long with several leaf nodes. Remove lower leaves, keeping 2-3 sets at top.

Dip cut end in rooting hormone (though they often root without it). Plant in well-draining potting mix, water well, and cover with plastic bag or dome to maintain humidity. Place in bright, indirect light.

Rooting takes 4-8 weeks. Once new growth appears, gradually acclimate to lower humidity. Transplant to final location when well-rooted. Knock Outs are very vigorous and should establish quickly!

Hey fellow rose lover! I've had great success with Knock Out rose cuttings using this simple method:

I take cuttings in September when growth has slowed but plants are still active. I use current season's growth that's starting to harden slightly. I remove all but the top two leaves and any flowers or buds.

My secret weapon: I use clear plastic cups so I can see root development! I put drainage holes in bottom, fill with moist potting mix, insert several cuttings per cup, and cover with another clear cup upside down as a dome.

I keep them on my porch out of direct sun and mist occasionally. By Thanksgiving, most have roots! I overwinter them in a protected spot and plant out in spring. The success rate is about 70% - amazing for free plants!
