Propagating a rose bush through cuttings is an easy process that may not always produce the results expected. Rose bush propagation is best done when the cuttings are taken from the plant during the months of November through February. The success rate for cutting propagation is 50 to 75 percent. The resulting rose may not be an exact match to the bush the cutting was taken from, as most hybrid roses are grafted onto hardy root stock.
Rooting Rose Cuttings
Disinfect all tools and workspace with a solution that is nine parts water and one part bleach. Allow everything to dry.
Take 6-to 8-inch rose plant cutting from the tip of a stem that recently bloomed with a sharp knife or pruning clipper making a 45-degree cut. Make sure the stem is healthy and disease free.
Remove all flower heads and hips to the first set of mature healthy leaves. Do not allow the cutting to dry out.
Dip the cut end of the stem into rooting hormone. Tap the stem lightly to remove excess hormone.
Stick the cut end of the stem 1 to 2 inches into a pot or Styrofoam cup holding moistened sterile potting media. Make sure there are drainage holes at the bottom to remove excess water. Write the date the cutting was planted to monitor the growth.
Keep the soil moist but not wet during the rooting process. Cuttings that dry out during the rooting process will not survive.
Transplant the new rooted rose stems in the fall in a location that receives at least eight hours of sunlight. Protect the plants from wind by pruning back tall shoots. Make sure the soil temperature is above 60 degrees Fahrenheit with the air temperature above 65 degrees for best results.
Begin fertilizing the new shoots the following spring with a rose fertilizer.
