Because the seed coat of Albizia Albizia is hard, in order to make the seeds germinate orderly and emerge quickly, it is necessary to soak them in 0.5% potassium permanganate cold water solution for 2 hours two weeks before sowing, rinse them with clean water after taking them out, and then soak them in hot water at about 80℃ for 30 seconds. After emergence, they grow vigorously and are not easy to get sick.
Raise seedlings in spring, soak seeds for 8- 10h before sowing, and then take them out for sowing. After all the seedlings emerge, it is necessary to strengthen the management of weeding, loosening soil and topdressing. Transplanting in the spring or autumn of the next year, with the plant spacing of 3-5 meters. 2-3 years after transplanting, weed and loosen nests in spring and autumn every year to promote growth. ?

Transplant management
Dense planting of Albizia Albizia can ensure the trunk to be straight, and the side branches should be trimmed in time during seedling raising. If you find a side branch, you should wipe it off from the root of the branch as soon as possible, because the side branch is often not cut thoroughly with a knife, which leads to the re-germination of the side bud. In the second year, the seedlings with inclined trunk can be cut off uniformly, which can promote the growth of thick and straight trunk;
Transplanting time should be in spring and autumn, and transplanting in spring should be before germination and when the juice has not flowed out; Planting in autumn can be carried out after the leaves of Albizia Albizzia fall and before the soil freezes. At the same time, it is necessary to water in time and set up supports to prevent the wind from lodging.
Management should prune and adjust the tree state every year to maintain its ornamental effect. In addition, basal fertilizer should be applied in late autumn and early winter every year to promote lush growth and more flowers in the coming year.
