How to reproduce Primula oleracea

1. Seed propagation

1. Collection

Although all plants have seeds, some plants' seeds are very fragile and need to be collected at the right time. The seeds of this plant are like this, tiny and short-lived. If left for a long time, they may easily fail to germinate. The seeds of this plant usually germinate within 20 days after being obtained.

2. Planting seeds

It starts to germinate about a week after planting, and a large number of seeds can germinate in the first three days. In order to ensure quantity and quality, sowing is generally carried out in June. If you sow in autumn, it will not be very conducive to germination, and even if it germinates, the plants will be very short and the flowers that grow will not look good, so try not to sow in autumn.

3. Notes

The size and weight of seeds are also very important. Larger seeds germinate better, while small seeds will be much worse. This may be related to the amount of nutrients inside the seeds, so it is also worth noting. After the seeds are planted, they need a certain amount of light to germinate, because the substances inside the plant need sunlight to be activated, but they must not be exposed to direct sunlight, otherwise it will affect the germination rate of the plant.

2. Cutting propagation

1. Methods

During the period from the end of August to the beginning of September each year, choose healthy plants, take a branch of appropriate size, leave buds at the bottom of the cut, and have a few leaves on the branch, and quickly dip it in indolebutyric acid for cuttings.

2. Notes

The soil for cuttings should be moist sand. Pay attention to the distance between the plants, leaving appropriate space for growth, and let the leaves hang down in the same direction without overlapping or touching the ground. After planting, you need to water it thoroughly and cover it with plastic film. Appropriate shading should also be carried out.

After making sure that the plant has survived, that is, after the roots begin to develop, it is necessary to remove weeds and apply fertilizer according to a certain cycle. After the cultivation reaches maturity, the plants can be transplanted, which is usually done before flowering so as not to affect flowering.
