1. Harvesting and treatment of seeds

Its seeds generally begin to mature from August to October. If we want to harvest them, we should try to choose some plants that are older, strong and disease-free, because they have a lot of seeds and good quality

After the fruits are harvested, we should spread them in a cool place in time and dry them. After a few days, these fruits will crack naturally. At this time, we can take a stick and start beating until the seeds come out. Then we can mix them with some river sand and store them. When storing, try to choose some cool and ventilated places, and the sand can't be too thick. During the storage, turn it over several times appropriately, and add additional water in time to maintain humidity. Then you can wait to plant

2. Preparation of soil

When preparing the soil, we should choose some loose, thick and breathable sandy loam, and then carefully sort it out, and add some base fertilizer to facilitate the full nutrition in the early stage. After the base fertilizer is added, we have to detoxify the soil, so that the seeds are not vulnerable to diseases and pests

3. Start sowing

We usually choose to sow in late winter or early spring. First, we take out the seeds hidden in the sand, and then sprinkle them on the prepared soil one after another. Then we can cover it with a layer of soil, and then start watering to make the soil contain a certain amount of water. After watering, we also need to cover it with a layer of straw, which can maintain the temperature. Basically, after 40 days, the seeds will begin to sprout and be unearthed

4. Post management

After the seeds are unearthed, we should timely remove the straw on it and cover it with arched plastic film. Almost 50 days later, these seedlings will begin to grow real leaves. In late March, the seedlings are basically all out. At this time, we should give it proper shade according to the weather conditions. In this way, the seedlings can be transplanted as soon as possible
