The propagation of palm bamboo can adopt the method of sowing propagation and branch propagation. The family planting is usually based on branch propagation.
Loose and permeable soil is chosen as the base of sowing, which is usually mixed with rotten leaf soil and river sand. The seeds can be soaked in warm water (30-35 ℃ for two days) before sowing, and then seeded when the seeds begin to germinate. Because of its irregular germination, the soil should be covered a little deeper after sowing. Generally, it can germinate within 1-2 months after sowing, and the germination rate can reach about 80%. When the cotyledons of young seedlings are 8-10 cm long, they can be transplanted. It should be noted that when transplanting, 3-5 plants should be planted in a clump to facilitate survival and growth.
Generally, it is selected in spring, combined with basin changing, to divide the original clump with more tillers into several clumps with a knife. When cutting, try to avoid damaging the roots and buds, so that each clump contains more than 8-10 plants, otherwise it will affect its growth and poor ornamental effect. After the ramets are potted, they should be placed in the half shade to keep moist, and the water should be sprayed on the leaves frequently to prevent the leaves from withering. After germinating new branches, move them to the sunny place for maintenance, and then carry out normal management.
