1、 Seeding:

1. At the end of December, when its fruit is cracked and its seeds are mature, we can collect long strip fruits. Dry the fruit, then take out the seeds with wings from the inside, rub them with your hands, remove the membranous wing fragments, and dry and store the remaining seeds until the next spring

2. When planting, first soak them in the water for 2 to 3 hours, then mix them with the wet sand, and then spread them thinly in the large basin in the shed. Keep the seeds and sand moist, and prevent mildew in the process. After they germinate, they can be planted in the ground

3. The stored seeds can also be soaked in water for 3 to 4 hours from March to April, then dried slightly, mixed with wet sand, placed on the seedbed, covered with a layer of thin soil, and then covered with plastic film to moisturize. When the buds grow, the film can be removed, and then a shed can be built to shade

2、 Cutting:

1. From March to April, when the average temperature is higher than 15 degrees, cut some wooden branches that have been growing for 1 to 2 years, cut them into 15 to 20 cm long shapes, and cut off some leaves

2. Put the branches on the bed and insert one-third to one-half of the branches
