In Southwest China, there is a kind of mysterious flower, which is chicory leaf Primula. This plant has blue and purple flowers, often growing in mountains and canyons, giving people a feeling of being tall outdoors. But this kind of flower is very common, and now there are many plants, so how should this kind of flower breed? Let's study now.

I. seed propagation

1. collect

Although all plants have seeds, some of them are very fragile, so they need to be collected at the right time. The seeds of this kind of plant are just like this. They are small and their life span is very short. If the time is long, they will not germinate easily. The seeds of this plant usually germinate within 20 days after being obtained.

2. sowing

After planting, germination begins about one week, and a large number of seeds can be germinated in the first three days. In order to ensure the quantity and quality, the seeds are usually planted in June. If it's autumn sowing, it's not very conducive to germination, and even if it's germination, the plant is very small, and the flowers are not beautiful, so try not to sow in autumn.

3. Precautions

The particle size and weight of seeds are also very important. Larger seeds germinate better, while smaller seeds are much worse. This may be related to the amount of nutrients in the seeds, so it is also noteworthy. After the seeds are planted, they need a certain amount of light to germinate, because the materials inside the plant need sunlight to activate, but they can never receive direct sunlight, otherwise they will affect the germination rate of the plant.

2. Cuttage Propagation

1. method

In the period from the end of August to the beginning of September every year, select healthy plants, take off a branch of appropriate size, the lower incision needs to leave buds, and there are several leaves on the branch, quickly dip in indobutyric acid for cutting.

The small flowers of the Primula.

2. Precautions

After inserting, it needs to be watered and covered with plastic film. Proper shading should also be done
