Selenicereus grandiflorus, commonly known as the Queen of the Night, is a cactus species native to the tropical regions of Central America and the Caribbean. It is an epiphytic cactus that thrives in seasonally dry tropical climates. The plant is famous for its large, fragrant, night-blooming flowers that last only for a single night. It has a dormancy period during the cooler months.
To care for Selenicereus grandiflorus, provide it with bright, direct sunlight for several hours a day. Maintain moderate temperatures and ensure the plant is kept in a humid environment. Water the plant sparingly, allowing the soil to dry out almost completely between waterings. During its dormancy period, reduce watering significantly.
Soil
Selenicereus grandiflorus prefers well-draining soil, such as a loam-based mix. Ensure the soil has good drainage to prevent waterlogging, which can lead to root rot. A cactus or succulent soil mix can be ideal for this plant.
Fertilizer
Fertilize Selenicereus grandiflorus with a balanced 10-10-10 fertilizer during the growing season. Apply the fertilizer every 4-6 weeks to support healthy growth. Reduce or stop fertilizing during the plant's dormancy period.
Repotting
Repot Selenicereus grandiflorus every 2-3 years or when it outgrows its current pot. Choose a slightly larger pot with good drainage. Gently remove the plant from its old pot, shake off excess soil, and place it in the new pot with fresh soil mix.
Propagation
Propagate Selenicereus grandiflorus through stem cuttings. Take cuttings during the growing season, allow them to callous over for a few days, and then plant them in a well-draining soil mix. Keep the cuttings in a warm, bright location and water sparingly until they establish roots.
Pruning
Prune Selenicereus grandiflorus to control its size and shape. Prune during the growing season by cutting back any overgrown or damaged stems. Use clean, sharp tools to make clean cuts and avoid damaging the plant.
Toxicity
Selenicereus grandiflorus is not known to be toxic to pets or humans. However, it is always advisable to keep plants out of reach of pets and children to prevent any accidental ingestion.
Additional
Selenicereus grandiflorus is a stunning plant that can be a focal point in any garden or indoor space. Its night-blooming flowers are a spectacular sight, and the plant's epiphytic nature allows it to grow in unique and interesting ways. Ensure it has adequate support as it grows, as its stems can become quite long and sprawling.
