It is easy to choose shallow flowerpots with strong air permeability and good water permeability. The soil matrix is required to be loose and fertile. Generally speaking, the soil is the most suitable. After the sun exposure or high-temperature disinfection, the thickness of loam can be distinguished through layers of screening.
The containers selected by Tong sihaitang must be cleaned or even disinfected, and the drain holes at the bottom of the basin must be padded with tiles to ensure the smooth drainage of the basin soil when watering.
The thick matrix is placed in the lower part of the basin, and the fine particles are added in the upper part. However, the matrix in the basin cannot be placed too much, and the best distance from the basin mouth is 2cm.
After that, spray it in the water, expose the basin surface, make the water penetrate from the bottom of the basin hole from bottom to top, wait for the basin soil to be wetted, and then sow.
The planting time of Begonia should be April to May and August to September.
First mix the seeds with the fine garden soil, and then evenly spread them to the surface of the basin soil, without covering the soil, use thin glass or plastic film for moisture preservation, place them in a cool and ventilated place, if put them in the greenhouse, shade them. The temperature of 15-22 ℃ is suitable for rooting and germination, about 1 week.
