1、 Curing method

1. Temperature: it can also be seen from its main distribution range that where primrose flowers like to be warm, generally speaking, it can be maintained between 18 and 25 degrees. It has certain cold resistance, but it also needs to be cold proof if it is cultured near the cold zone

2. Light: primrose likes light, but the most suitable light is moderate light. In other words, its growth environment should not be too dark, but it should not have too strong light. Generally speaking, it is more suitable for its growth in the astigmatic environment. But in winter, there is no need to adjust, because the sunshine itself will not be too strong

3. Watering: in the growing season, primrose flowers have a large demand for water. They can't wait for the substrate to dry for a long time before watering. They need to be supplemented when it is semi dry. It is best to let the substrate be wetted without ponding. In winter, it may sleep and can't water too much at this time

4. Fertilization: primrose does not need much fertilizer, but it can only be fertilized in spring and autumn, usually once a month

2、 Breeding skills

1. Reproduction: the method of seed collection and sowing can be used. When the color of the fruit turns yellow, the seeds can be collected. After drying in the shade, the shell outside the fruit can be removed, and then the seeds can be stored. The method of "pot sowing" can be adopted. Directly sprinkle the seeds into the basin, and then it is very important to keep warm and moisturize. When the surrounding conditions are suitable, it can germinate after five or six days

2. Changing basin: there are some restrictions on the quality of soil. The two main requirements are its drainage and air permeability. Therefore, it is best to replace the matrix every one or two years. After replacing the basin soil, first put it in a semi shady place and wait for it to adapt to maintenance for a period of time

3、 Problem diagnosis and treatment

1. Disease: a frequently occurring disease is "brown spot", which will occur from top to bottom, which will lead to yellowing of leaves and affect flowering. This part of the infected areas can be cut off, and then reduce the application of nitrogen fertilizer

2. Pests: "aphid" and "red spider" are the two most common pests, which often gather in leaves and flowers. It can be controlled with insecticides, and pay attention to cleaning up the eggs

4、 Other issues

1. Toxicity: it's non-toxic. Don't worry

2. Whether it can be raised at home: it is a kind of better ornamental plants, which can be raised at home< a>
