Primula auricula, commonly known as auricula or bear's ear, is a perennial plant in the family Primulaceae. It is native to the mountains of central Europe, where it thrives in subalpine and subarctic climates. The plant is known for its attractive rosettes of leaves and clusters of colorful flowers. It has a dormancy period during the winter months.
Primula auricula requires moderate temperatures and indirect bright light for optimal growth. It prefers a humid environment and should be watered when the soil partially dries out. The plant can be grown both indoors and outdoors, making it versatile for different settings.
土壤
Primula auricula prefers well-draining loam soil with a slightly acidic to neutral pH. The soil should retain some moisture but not become waterlogged. Good drainage is essential to prevent root rot.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize the plant during the growing season, typically every 4-6 weeks, to support healthy growth and flowering.
换盆
Repot Primula auricula every 1-2 years or when the plant outgrows its current pot. Choose a slightly larger pot with good drainage. Repotting is best done in the spring before the growing season begins.
传播
Primula auricula can be propagated by division or from seed. Division is best done in the spring or early autumn. Carefully separate the rosettes and replant them in suitable soil. Seeds can be sown in a well-draining seed mix and kept moist until germination.
修剪
Pruning is necessary to remove dead or damaged leaves and spent flower stalks. This helps maintain the plant's appearance and encourages new growth. Prune as needed throughout the growing season.
毒性
Primula auricula is not toxic to pets or humans. However, some individuals may experience skin irritation from handling the plant, so it is advisable to wear gloves when pruning or repotting.
额外的
To ensure healthy growth, avoid overwatering and provide good air circulation around the plant. Protect the plant from extreme heat and direct sunlight, which can cause leaf scorch. Regularly check for pests such as aphids and treat them promptly if found.
