1、 Seed taking

1. Yulu itself will not bear seeds, so it should be pollinated manually. When pollinating, it is best to choose two flowering varieties with good growth as parents in windless and sunny weather. The leaves are compact, round and full, and the artificial pollination can be carried out

2. Remove the petals of two flowering plants, dip the pollen with a brush and point it on another plant. You can also save the pollen and operate it the next morning, so that the success rate is higher. After pollination, the flowers will bear seeds, which can be picked when the seeds are mature

2、 Sowing time

Generally, seeds can be sown after picking, with strong vitality. Seeds can also be dried and put into the refrigerator for refrigeration. Seeds can also survive in summer

3、 Operation method

1. Vermiculite, rotten leaf soil and peat soil are mixed in the ratio of 3:2:2, and heated with hot water or microwave oven for high-temperature sterilization, which can reduce the probability of disease

2. The method of sowing seeds at a certain distance and sowing them casually can also produce seedlings, but they may overlap and compete for nutrients. Spray some water with a watering can and cover it with plastic film or glass to reduce water loss. Seedlings will appear in about half a month to 20 days

3. After the emergence of seedlings, remove the glass, put it in a ventilated place, and spray a little water. Don't make the culture substrate too dry

4、 Post management

1. In the later stage, when the seedlings enter the growth period, the sick seedlings and weak seedlings will be cleared out. The over dense planting will affect the overall growth momentum and be transplanted to other pots in time

2. The soil quality after transplanting is not specified, but it must not be too thick soil. The selection principle should follow the principle of good ventilation and drainage. Vermiculite and charcoal can be used and other mixtures can be added

3. The plants planted by seeds are uncertain and may mutate. If there are other good-looking healthy varieties, they can stay
