Selenicereus megalanthus, commonly known as Yellow Pitahaya or Dragon Fruit, is a cactus species native to tropical regions. It is known for its large, fragrant, night-blooming flowers and edible fruit. The plant thrives in wet tropical climates and is often grown for its unique and nutritious fruit.
Selenicereus megalanthus requires bright, indirect light and moderate temperatures. It thrives in high humidity and should be watered when the soil partially dries out. The plant can be grown both indoors and outdoors, provided it receives adequate light and warmth.
收成
Selenicereus megalanthus, commonly known as yellow pitaya or yellow dragon fruit, is typically ready for harvest about 180 days after planting. The fruit should be harvested when the skin turns a bright yellow color and the scales on the fruit start to separate slightly. To harvest, use a sharp knife or pruning shears to cut the fruit from the plant, taking care not to damage the stem or the fruit itself. It is important to handle the fruit gently to avoid bruising. Harvesting is usually done in the early morning or late afternoon to avoid the heat of the day, which can stress the plant.
土壤
The plant prefers well-draining loam soil with a slightly acidic to neutral pH. Ensure the soil mix allows for good drainage to prevent root rot. A cactus or succulent mix can be used for optimal growth.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to support healthy growth and fruit production.
换盆
Repot the plant 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.
传播
Propagate Selenicereus megalanthus through stem cuttings. Take cuttings from healthy stems, let them dry for a few days to form calluses, and then plant them in well-draining soil. Keep the soil slightly moist until roots develop.
修剪
Prune the plant to remove dead or damaged stems and to shape it as desired. Pruning can be done during the growing season to encourage new growth and maintain a manageable size.
毒性
Selenicereus megalanthus is not toxic to pets or humans. The fruit is edible and highly nutritious, but always ensure it is properly cleaned before consumption.
额外的
Ensure the plant is protected from frost and extreme cold, as it is not frost-tolerant. Regularly check for pests such as mealybugs and spider mites, and treat them promptly to prevent infestations.
