What are the propagation methods of Dendrobium officinale

Dendrobium officinale propagation method: division

Choose plants with dense growth. After they have bloomed, take them out of the pot, remove the old ones, and cut them from the base of the clumped stems. Try to damage the roots as little as possible when cutting, and only cut the parts that are connected to each other. Open the roots with your hands, and do not use a knife to cut them. Treat the main plants as a group and further remove the old roots. Place the new sprout close to the center of the pot, fill in new substrate and compact it to form a new plant.

Dendrobium officinale propagation method: bud division

When plants that have been potted for more than 3 years or some of the stems of Dendrobium officinale have small plants growing on the top or base, they can be propagated by cutting buds. Select a small plant with 3-4 leaves, 2-3 roots and a root length of 4-5 cm, cut it from the mother plant, treat the wound with wood ash or 70% mancozeb, and plant the seedling in a pot. Wang intended to plant shallowly. After 2 years of cultivation, it will generally bloom and become a commercial flower.

Dendrobium officinale propagation method: cuttings

Cutting propagation can be carried out together with repotting and division after flowering. Stone Touch Orchid has a slender, fleshy stem with many nodes, on which buds can grow, so it can be propagated by cuttings. Choose unflowered and relatively full branches for sowing, cut the branches into several sections, each with 2-3 nodes, and apply wood ash or 70% mancozeb on the wounds to treat them.

Insert the stems section by section into a substrate mixed with moss and peat, with half exposed, and place them in a semi-shaded and humid place. No need to water for one week after planting, then spray frequently to keep moisturized and provide appropriate shade.

After 1-2 months, new buds will grow at the nodes, and 2-3 small roots will grow under the new buds to form new plants. Put the new plant together with the old stem into the pot, and it will bloom after 2-3 years of cultivation. The best time for cuttings is from April to August.
