How to grow Primula

1. Maintenance methods

1. Temperature: Primula prefers slightly lower temperatures, preferably between 12 and 22 degrees. This range is most suitable for its growth. Specifically, the temperature should be around 20 degrees during the day and slightly lower at night. In winter, just keep the temperature above five degrees. In summer, it is best not to exceed 30 degrees.

2. Light: The spring lettuce likes light, but it is also afraid of too strong light. In order to ensure its normal growth and flowering, it is best to place it in a location with good sunlight. However, try to avoid strong light in summer and autumn. Especially when the temperature is very high, more attention should be paid to shading.

3. Watering: When the lettuce is in the seedling stage, it does not need too much water. Watering too much will cause damage to the root system. During its growth period, just keep the substrate semi-moist. It should not be too humid, and there should be no accumulation of water.

4. Fertilization: Primula oleifera prefers fertilizer. During the growing period, fertilizer should be applied basically every week. However, do not get the fertilizer on the leaves and flowers.

After collecting the seeds, it is best to remove those that are too small or of poor quality. After preparing the substrate or choosing the sowing location, you can sow the seeds. After sowing, there should be no strong light and the temperature should not be too low.

2. Pruning: The pruning of Primula altissima mainly focuses on its leaves and flowers. Normally, there may be leaves that are dry or turn yellow due to various reasons, and they need to be cut off in time. Then after the flowers have bloomed, cut off the remaining flowers.

3. Problem diagnosis and treatment

1. Diseases: The seasons when diseases often occur are summer and autumn, especially when the temperature is high and the humidity is high. In order to prevent the disease from becoming more serious, it is necessary to spray pesticides in time and cut off the diseased parts.

2. Pests: The main types are aphids and so on. If you find pests, spray them promptly to prevent their numbers from increasing further.
