Let's start with the seeds. The early seeds must be well cultivated, or the sowing will not go on. The seeds of Spiraea Ma Ye usually bloom in 2-3 days, and then they will be able to bear after four days. It has little dormancy. It is the characteristic that flowers bloom in all seasons. The seeds can be soaked in warm water (temperature is 30 ℃) for one day and one night, then taken out and put in a dish (General specification is OK) lined with a wet filter paper, waiting for 8 days to 10 days in the room with temperature of 18-20 ℃ to germinate.
The time of sowing is generally in early summer. You can choose to sow in the courtyard or in the indoor potted plant. However, the autumn sowing in the southern suburbs can sprout quickly and overwinter in the form of seedlings. And Beijing suburb can sow in early April, and Nanjing suburb can sow in early March.
After sowing, the soil will be covered with 0.5-1.0 cm, and plastic film will be covered. It can be excavated in 7-10 days, and the primary leaves will grow in 7 days. The height of this year can reach thirty or forty centimeters. It will bloom in about three years.
If Spiraea directly bell in the tree, can play a shade effect. In this way, the seeds can grow faster in the germination stage, and can let the little seedlings come out more.
The above may be complicated. There is also a simple saying that the so-called sowing and propagation technology is to sow or dry store the chrysanthemum to spring next year. Before sowing, the soil should be soaked with water, then sown, and then covered with a layer of soil, which can germinate in a week or so.
