How to grow primrose well

1. Maintenance methods

1. Temperature: As can be seen from its main distribution range, primrose likes warm places, which can generally be kept between 18 and 25 degrees. It has a certain degree of cold resistance, but if it is raised in an area close to the frigid zone, it also needs to be protected from the cold.

2. Light: Primrose likes light, but the most suitable light for it is moderate light. That is to say, its growth environment cannot be too dark, but it cannot have too much light either. Generally speaking, it grows better in an environment with diffuse light. But in winter, there is no need to adjust it because the sunlight itself is not too strong.

3. Watering: Primroses have a relatively large demand for water during the growing season. You cannot wait until the substrate has dried out for a long time before watering it. You need to replenish water when it is half dry. It is best to keep the substrate moist but not waterlogged. In winter, it may go dormant and you should not water it too much at this time.

4. Fertilization: Primrose does not require much fertilizer and can be fertilized only in spring and autumn, usually once a month.

2. Breeding techniques

1. Reproduction: You can use the seed collection and sowing method. When the color of the fruit turns yellow, you can collect the seeds. After drying in the shade, you can remove the outer shell of the fruit and store the seeds. You can adopt the "pot sowing" method. Sow the seeds directly into the pot, and it is very important to keep them warm and moist. If the surrounding conditions are relatively suitable, they will generally germinate after five or six days.

2. Repotting: There are some restrictions on the quality of the soil. The two main requirements are its drainage and air permeability. Therefore, it is best to replace the substrate every one or two years. After changing the potting soil, place it in a semi-shaded place first and wait for it to adapt to the environment for a period of time.

3. Problem diagnosis and treatment

1. Disease: A common disease is "brown spot disease", which can occur from top to bottom, causing the leaves to turn yellow and affecting flowering. You can cut off the diseased areas and reduce the application of nitrogen fertilizer.

2. Pests: "Aphids" and "red spiders" are the two most common pests, which often gather on leaves and flowers. It can be controlled with insecticides, and be careful to remove all insect eggs.

IV. Other issues

1. Toxicity: It is non-toxic, no need to worry.

2. Can it be grown at home? It is a good ornamental plant and can be grown at home.
