In December, mature Phoenix seeds were collected and exposed to the sun. The pods could split naturally, or they could be knocked with wooden sticks to make the seeds fall off. The seeds were packed in gunny bags and stored in a cool, dry and ventilated place. The vitality could be preserved for more than one year. The next spring sowing.
Because the seed coat of Phoenix wood is dense and hard, and it is difficult to absorb water, it is necessary to heat the seed with hot water at 80 ℃ before sowing, soak it for one day, then cool it with cold water naturally, and then soak it with warm water at 50 ℃ for one day after cooling. Take it out, wash it and drain it, and then spread it on the seedbed. The depth of covering soil is about 0.5-1cm. After that, we should keep warm, water the soil once in the morning and evening, keep the soil moist, and germinate about a week.
When the seedlings grow to more than 8 cm, they are divided into beds and some branches and leaves are trimmed. At the early stage, the compound fertilizer can be applied, and the nitrogen fertilizer can be applied less. After autumn, the fertilizer can be stopped to promote its early lignification. In winter, the leaves that have not fallen off are cut off manually. The seedlings of Phoenix are sensitive to frost. It is necessary to use the method of film covering or single plant wrapping to keep warm and prevent frost.
