Get your rose clipping. It should be four to six inches long.
Fill a clear vase with water and place the rose clipping in the vase.
Wait four to six weeks. In this time, small roots should begin forming out of the base of the clipping. Make sure to gently add clean water every few days.
When the new roots are three to four inches long, remove the rose from the vase and carefully plant the rose in a small pot. If the rose has been inside during the duration of the rooting process, it may be best to keep the bush inside in a brightly light area to avoid having the plant go into shock.
Water the rose daily. After a few weeks small leaves should begin forming on the new rose bush. If it is warm enough the plant can be moved outside. Make sure to place the rose in a protected area.
Tend the rose until it is ready to plant in the garden. Depending on when the clipping is first started this could take three or four months in the spring and summer or up to a year if begun in the winter.
