The easiest and most inexpensive method of propagating roses is to take a stem cutting. This method works very well with miniature roses and climbing varieties. Hybrid tea roses and floribundas present more of a challenge because they are produced by grafting two different roses on one stem. There is a chance that the rose produced from a cutting will not look anything like the rose from which the cutting was taken. It takes about three years for the new rose to become established but the results are well worth the wait.
Cut a green cane from an established rose bush that is about 1 to 2 feet long. Remove the thorns so the cutting is easy to handle.
Cut the cane in about four pieces. The bottom of each piece should be cut near a leaf node. Mark the bottom with a felt tip pen then remove all but two leaves. If a section does not have any leaves at all it can still be used.
Dip the bottom of each piece in rooting hormone powder. This will enable the cutting to activate its energy into producing roots.
Fill a flower pot with potting soil. Stick the bottom of the cutting into the soil at least two-thirds of the length.
Spray the cutting and surface of the soil with water in a spray bottle until it is very moist. Place a plastic bag over the top of the pot and cutting and secure it with a string or rubber band.
Place the pot outside in an area that has filtered sun. If the soil gets dry remove the plastic, mist with water and replace the plastic.
Watch for the stem to grow and produce new leaves. This will happen in four to eight weeks. To be sure the cutting has taken root, tug lightly and if it seems stable, it has roots. Remove the plastic and let the pot sit in the garden in filtered sunlight for a few days before planting in the ground.
