In August to October every year after the flower, you can harvest its mature seeds, harvest immediately after sowing
We said that seeds should be sown immediately after harvest, so the best planting time is in autumn. Sometimes seeds can be preserved until next spring.
When planting it, the first thing to do is to make sure that the plant distance is 45 to 60 cm, and the best depth is 7 to 8 cm. Of course, it can also promote cultivation. After the seeds are planted, cover them with vermiculite, keep a certain humidity, and keep the temperature between 18 and 21 degrees. After a period of time, they will give out buds.
When the bud grows, it can be moved to a place with more light and good ventilation. Then apply a small amount of nitrogen fertilizer to control the temperature of 21 ℃ in the daytime and about 10 ℃ in the evening, and this temperature must be maintained until it grows a fifth leaf.
Then the water supply and humidity should be about 70%. Soon it will grow leaves. When it grows two real leaves, it can be potted. After potting, the initial temperature should be between 15 and 18 degrees. After a week, the temperature can be reduced to 10 degrees, and then to 5 degrees. When spring comes, it can be raised with natural temperature. Protect it, and at this time can also normal fertilization
