Roses are the crown jewel of many gardens because of their beautiful blooms and wonderful scent. Taking cuttings from a rose bush is an easy way to propagate a rose plant you like without having to buy a new one. Take cuttings from a rose bush in the late spring or early summer, after the rose bush has bloomed and the petals are falling off or fading. (ref 1 and 2)
Choose a rose stem that produced flowers. The stem should be straight and have no discoloration, which indicates mold or a fungal infection. The rose's stem should also be slightly pliable and no thicker than a pencil.
Remove all the remaining flowers from the rose stem and all but four or five leaves.
Cut the stems at a node. Each cutting should be 8 to 12 inches long.
Place the rose cuttings in a plastic bag, seal it and place it in a refrigerator for 24 hours.
Put each cutting in moist potting soil in a small pot. It will take three to seven weeks to form roots.
