Care Instructions
Cypripedium calceolus requires bright, indirect light and moderate temperatures. It thrives in high humidity and should be kept evenly moist. Avoid direct sunlight as it can scorch the leaves. Ensure good air circulation to prevent fungal diseases.Soil
This orchid prefers well-draining loamy soil that retains moisture without becoming waterlogged. A mix of loam with organic matter such as leaf mold or compost is ideal. Ensure the soil is slightly acidic to neutral.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize during the growing season, typically every 2-4 weeks. Reduce or stop fertilizing during the dormancy period.Repotting
Repot Cypripedium calceolus every 2-3 years or when the plant outgrows its pot. Repot in early spring before new growth starts. Use fresh, well-draining soil and ensure the rhizomes are just below the soil surface.Propagation
Propagate by division in early spring. Carefully separate the rhizomes, ensuring each division has at least one growth bud. Plant the divisions in fresh soil and water thoroughly.Pruning
Pruning is generally not required for Cypripedium calceolus. Remove any dead or yellowing leaves to maintain plant health and appearance.Toxicity
Cypripedium calceolus is not known to be toxic to pets or humans. However, as with all plants, it is best to avoid ingestion.Additional
Ensure the plant has a cool period during winter to mimic its natural dormancy. This helps promote healthy growth and flowering in the following season.REVOLUTIONIZE YOUR PLANT CARE
