Cypripedium californicum, the California lady's slipper, is a member of the orchid genus Cypripedium, the lady's slipper orchids, native to the western United States.
California lady's slipper generally shows strong resistance to disease and is subject to relatively few insect pests. Its care is regarded as difficult because it needs a high-humidity but well-ventilated environment with minimal harmful pathogens. Excessive watering can cause root rot. Although anyone can grow California lady's slipper, keeping it healthy and getting it to flower again requires greater growing experience.
How to keep Cypripedium Californicum.
Water
The California Lady's Slipper needs sufficient moisture but can tolerate some drought conditions. To maintain the moisture in its substrate, water the plant weekly during the summer and once every 10 days in the fall and winter. In dry weather, it's beneficial to mist the plant. Always use water with a neutral pH. You can achieve this by allowing tap water or rainwater to sit for a while before using it.
Fertilizer
One fertilizer application in spring is typically enough for California lady's slipper, though multiple feedings can maximize growth. Feed every month to six weeks. Fertilizing improves leaf appearance and function, helping maintain even color and a healthy texture. It also encourages root growth and nutrient absorption for the plant's long-term health.
Pruning
Known for its distinct slipper-shaped flowers, the California lady's slipper benefits from early spring pruning. Trimming away dead stems during this time improves growth and airflow. Gentle, strategic pruning can enhance flowering and promote vigor while preserving the plant's natural shape. However, avoid heavy pruning, as the plant grows slowly.
