1、 Sowing time

There is no clear boundary between sowing time and four seasons. Manufacturers cultivated in large quantities in the south usually choose to plant seeds from November to August, so that the time of blooming flowers coincides with may day. Usually the north will choose spring sowing. In fact, the sowing time is mainly determined by the temperature, which can be higher than 15 degrees

2、 Sowing method

1, prepare a foam box with a culture medium, preferably using soft soil and good fertility. After sterilization, seed can be sowed. p>

2. After the seeds are sown, moisten the soil with a watering can and slightly moisten it. Excessive humidity will affect the germination rate. It is covered with a thin layer of soil and vermiculite. The temperature is maintained at about 24 ° C at room temperature

3、 Emergence management

1. Seeds do not need light for budding. Radicle will be produced in about three or four days, and budding will be almost successful in about a week

2. After the radicle comes out for about a week, the leaves of the seedling will also come out. At this time, the temperature should be reduced. After the substrate is dry, it is necessary to supplement water to provide nutrition for the extension of the root pair. When the leaves are about to appear, you can apply a little liquid fertilizer to help

3. For a long time, you will find that the seedlings grow very fast and enter the growth period. At this time, you should control the humidity and spray water after the soil is dry. This degree should be controlled by yourself. Don't be too dry and lack of water. The ambient temperature can also be appropriately reduced to about 18 degrees and continue fertilization

4. In the second half of the fast-growing period, the growth is basically stable, and the root system has been formed. When the seedlings grow to 34 cm and grow six leaves, they can be cooled down to a minimum of 15 degrees. They can receive sunlight properly and be ventilated regularly. After a while, it can be transplanted in pots. The watering must be well controlled, and the second water supply can be carried out after the substrate is dry
