- Make a small incision on the stem, just below the node, to encourage rooting.
- Cover the node and the incision with soil and secure in place with a small stake.
- Keep the soil consistently moist and allow the stem to root in place.
- After several months, cut the new plant from the mature plant and transplant to a new container or in the soil.
Propagation by Grafting
Grafting is another method used for propagation of tea plants like Thea bohea L.:
- Select a healthy and disease-free stem of a mature plant (rootstock).
- Choose a compatible variety and select a healthy shoot to use for the graft (scion).
- Make a diagonal cut on both the rootstock and the scion.
- Fit the scion onto the rootstock and secure with grafting tape.
- Keep the graft moist and in a shaded area until the graft has taken.
- Transplant the new plant to a container or in the soil when it has established.
Overall, Thea bohea L. can be propagated in a variety of ways - from seeds, cuttings and layering, or grafting. Choose the method that works best for your needs and skill level.
