1、 Sowing method

1. Sowing time: sowing time is generally carried out in spring or autumn. The temperature in these two periods is appropriate and can promote the growth. The best time is in March, and the warmer temperature is beneficial to the seedlings

2. Seed selection and seed collection: since only single petal long-lived flowers will have seeds, there are few choices. In addition, because the seeds are small, it is not convenient to pick the seeds, which requires more careful selection

3. Substrate production: seeds have strict requirements for the growth environment. The slightly acidic soil is selected, and the pH is controlled between 6.0 and 6.5. Mix peat, sand and vermiculite according to 1:1:4, and then disinfect

4. Sowing process: Sprinkle the seeds of Changshou flower evenly on the surface of the substrate, and then gently press the substrate without covering it with soil. Then cover it with plastic film and place it where there is astigmatism. The temperature is controlled at about 17 ℃. It can germinate in about ten days. Remove the film after germination

2、 Seedling maintenance

The maintenance of young seedlings of long-lived flowers is particularly important. The first is the temperature control. Too high or too low temperature will cause the seedlings to stop growing or even die, so it needs to be kept warm. The second is the problem of light. Seedlings should not be exposed to direct sunlight to avoid water evaporation. In addition, do not water too much to make it wet, but do not accumulate water. Pay attention to these aspects and the seedlings will grow healthily
