1. Time: the seeds of this kind of plants mature before winter. After harvest, the fruits will be preserved until the next year when spring comes, about between January and February. At this point, the peel and pulp will be washed out, only the seeds.
2. Flowerpot: choose how large flowerpot to use according to how many seeds you harvest. If you have more seeds, you can use a wooden box. If you have fewer seeds, you need to choose a small flowerpot.
3. Soil: fine sand soil with good drainage performance and permeability can be used, and then a little water can be sprayed on the soil to make the soil layer a little wetter.
4. Sowing: spread the seeds on the basin soil, pay attention to the distribution density of the seeds, not too concentrated. Then cover the seeds with a little soil, not too much. Put the flowerpot in the water to soak the soil, and then cover it with a plastic film. The film can be removed after the seeds germinate. When the leaves grow 4 - 5, they can be transplanted.
The germination rate of this kind of plant is relatively low, so it is necessary to plant some seeds so that it is possible to cultivate seedlings.
