Ringing roses to facilitate propagation by cuttings

The stem or branch of the rose is ringed the latter part of July or August, causing the formation of a callus before the cutting is removed in November. Cuttings thus treated strike root much more readily than ordinary cuttings, which can make roots only after having formed a callus. By this method the propagation of varieties which can not be propagated by cuttings except with great difficulty, is rendered simple. Several rings may be made on the same branch by observing the proper distance for cuttings.
