1. Sowing and propagation

When the fruit opens in autumn, collect the seeds and put them in a ventilated place in the house to dry. After the fruit splits, you can take out the seeds. Its seed coat is very hard, and the treated seeds can germinate faster. You can cut the seed coat with a knife or soak the seeds with water

After the seeds are sown, they should be covered with plastic film to prevent water loss. Keep the temperature at 18-25 ℃ to ensure sufficient light, but prevent direct sunlight. Ventilate every day, clean weeds and prevent pests. The seeds will germinate after one month

When the seedlings grow 3 or 4 leaves, you can move the seedlings to the flowerpot for planting. Plant one tree in one flowerpot. Put the flowerpot in a ventilated place and water it thoroughly. After seven days, the roots will grow in the pot. You can appropriately increase the light and apply fertilizer

2. Cutting propagation

Select the healthy and robust semi lignified branches at the top of the tree crown, with a length of about 10cm. Remove the lower leaves and leave 2 or 3 leaves at the top for cutting in May, June or September and October. Cuttings shall be carried out immediately after the branches are cut. After cutting, the soil shall be compacted, watered thoroughly, placed in a cool and ventilated place, sprayed with water once or twice a day to prevent water loss and the soil from drying. The temperature shall be maintained at 20-25 ℃, and the light shall be gradually increased. The branches will grow roots after 1 or 2 months. At this time, the branches can be moved into the flower pot

3. Strip propagation

This method can get larger seedlings, and the operation is simple and easy to survive, but the disadvantage is that it can not breed in large quantities. This method can be carried out throughout the year, and April and June are the most appropriate. Specifically, first select healthy and strong branches, cut the width of about 0.5 ~ 1cm with a knife ring at a distance of about 30 and 40cm from the upper part, then wrap the wound with wet soil, tie up the upper and lower parts with plastic bags, and cut off the branches for planting after the roots grow on the branches
