1. Select container

It may grow taller, up to about two meters. Therefore, we have to choose a larger container, but we don't need to be very large at the beginning, because we may change pots and other treatments during maintenance. Another thing to pay attention to is the drainage of the basin. Flowerpots with particularly poor drainage cannot be used

2. Collection and treatment of seeds

The time of seed collection is usually in early August. After collection, it should be stored indoors in a cool place, not in the sun, otherwise the seeds will not germinate easily. Before sowing, in order to break its dormancy, it needs to be soaked in warm water of about 50 degrees

3. Choice of time

The interval between collection and sowing should not be too long. Sowing should be carried out immediately after collection and treatment, and must be carried out before October at the latest

4. Sowing

First, disinfect the prepared soil and mix some base fertilizer, so that the survival rate of seeds will be higher. After treating the soil, put it into a container and sprinkle the seeds

5. Later management

First of all, in order to prevent the excessive evaporation of soil moisture and block the strong sunlight, we can cover some plastic films. In addition, do not water too much, otherwise the soil will harden. If the sowing time is late, that is to say, the temperature is very low, appropriate cold prevention measures must be taken, such as covering some straw, leaves and so on
