Seed selection

This is the first step, which is directly related to the success rate of subsequent sowing, so we must be careful. We'd better choose the seeds collected in that year, which are plump and free of deformities or diseases and pests

Disinfect

There are two things we need to disinfect. The first is to test the seeds. We can soak them in water at about 60 degrees Celsius and wait for about 15 minutes. The second is the disinfection of substrates. They can be directly heated in a pot, which can scald the pests. These two kinds of disinfection are relatively simple to implement

Germination treatment

Prepare warm water and soak the seeds treated in the previous step for half a day to a day until we observe that the seeds have absorbed enough water and swell. This work is not necessary, and it can also be omitted for seeds that are easy to germinate

Sow

Next is the formal sowing. Put the seeds on the substrate one by one. If it is not easy to pick them up, you can also use small tools such as toothpicks. After sowing, cover it with a layer of substrate, about one centimeter. Then, put the container into the water so that the depth of the water is about half of its height, and let the water come up slowly

Post management

If it is sown in the cold time such as the late autumn or early spring, in order to maintain the temperature, the container can be wrapped with plastic film. However, after the seeds germinate, the film should be removed in time so that the plants can receive sunlight

After the emergence of plants, there may be some unhealthy seedlings. We should pull them out in time
