Seed selection

Seed selection before sowing is the main step for successful sowing

Before sowing, the seeds collected in the current year should be selected. The selection standard of seeds is to have full particles, no deformities, no diseases and pests

After selecting the seeds, the seeds should be disinfected. Generally, they can be soaked and disinfected with hot water at about 60 ℃

Flower seed germination

Before sowing, it is conducive to the germination of blue stars

The method of germination is to soak the seeds in warm water for a period of time, about 12 ~ 24 hours, until the seeds absorb water and expand

Sow

Prepare the soil and put it into the flower pot. Put the seeds on the pot soil and arrange them one by one. Then put the seeded flowerpot into the water. The depth of the water is 1 / 2 ~ 2 / 3 of the height of the flowerpot. Let the water soak up slowly and soak the soil. After that, you can use sprays and sprinklers for watering. After seeding, watering is proper. Note that the intensity of watering should not be too large, so as not to rush the seeds that have not yet been properly rooted. p>

Manage

After sowing, we should wait for the blue star flower to grow slowly, but we should pay attention to the following points in daily management:

In late autumn, early spring or winter, when the temperature is low or encounter cold current and frost, you can wrap the flowerpot with plastic film, or put it in the greenhouse and indoor for heat preservation and moisture retention

After the seedlings are unearthed, the seedlings should be exposed to the sun, otherwise it will lead to poor growth of the seedlings

After most seeds are ready, the seed spacing needs to be managed

Pull out the diseased and unhealthy seedlings, leaving healthy and healthy seedlings

When most seedlings grow three or more leaves, they can be transplanted
