1、 Collect seeds

When the fruit is ripe, the seeds can be taken out from the middle. Before sowing, it should be treated, because the shell is hard and it is difficult to sprout and survive without treatment. You can wrap the sand with wet sand, put it in a sunny place, use high temperature to promote germination, or soak it in warm water, soak the seeds in warm water, take them out 2-3 hours after cooling, then cover it with a wet cloth and put it in the greenhouse to promote germination. After the seeds have cracks, you can sow them

2、 Start sowing

The sowing time is different in different regions. North China can be sown in mid April, while Northeast China can be sown in early May because of the cold climate. Before sowing, select a suitable substrate, and then put the seeds in. The navel should be placed flat on it, covered with 2-15cm thin soil, and poured with water

3、 Post sowing curing

In the later stage, the seedlings will grow gradually. After the seedlings grow well, they should be watered less to avoid water accumulation. If there is too much water, it will lead to decay and death. We should also apply fertilizer appropriately and more phosphorus fertilizer, so as to prevent overgrowth

4、 Conduct colonization

It can be planted in spring and autumn. First dig out a small pit, and then plant the plant upright, and the root system should be relaxed
