Growing roses from cuttings is an inexpensive and easy way to grow a new rose. It is also the best way to replicate a favorite or antique rose, as the new rose will be identical to the parent plant. Increase your chances of success by taking four or five cuttings, as not all cuttings will root successfully. Take rose cuttings any time of year from stems that have just finished blooming.
Use clean, sharp pruners to cut a to 8-inch tip from a rose stem that has recently finished blooming. Remove the wilted bloom or hip and strip off all the leaves. Cut the bottom of the stem at an angle to remind you which end should be planted. Keep the cuttings in a cool, shady place until you're ready to plant them.
Fill a container with commercial potting soil that has been dampened ahead of time. Any container will work, as long as the container has drainage holes in the bottom.
Dip the angled end of the stem in powdered rooting hormone. Plant the stem in the potting mixture, with the bottom half of the stem buried in the soil. Several stem cuttings can be planted in the same container, as long as they aren't touching.
Put a clear plastic bag over the container and secure the bag around the container with a rubber band. Place a bent wire clothes hanger or some small sticks in the bag to prevent the bag from dropping down on the cuttings.
Place the container in bright sunlight away from hot, sunny windows. Check the potting soil daily. Although the plastic will keep the environment in the bag damp for up to several weeks, the potting soil should be misted immediately whenever it feels dry to the touch. The soil should be damp, but never dripping.
Allow the cuttings to grow until the following spring. At that time, plant each cutting in a 5 to 6-inch pot and allow the cuttings to grow for a few more weeks, or plant them directly into the garden. The rose cuttings should be planted where they will be in sunlight for at least six to eight hours per day. Keep the soil damp.
