How to Propagate a Russian Sage
- 1). Plan your propagation of Russian sage for the late winter or early spring. Take root cuttings from an existing plant. Select roots from the base of the shrub that are about 1/4 inch in diameter, and use a sharp pruning knife to cut them away.
- 2). Place the cutting in some prepared potting soil and keep it moist. Once the plants have established themselves, they may be transplanted to an area with well-drained soil and full sunlight.
- 3). Cut away some stems from a Russian sage in the early summer to propagate another way. Treat the freshly cut stems with rooting hormone and plant them in containers with a rich mix of potting soil.
- 4). Allow the planted stems to become established in a greenhouse or similar humid environment until they are ready for transplanting,
