Cereus jamacaru, commonly known as the Mandacaru or Cardeiro, is a cactus species native to Brazil. It is a succulent tree that can grow up to 10 meters tall and is well-adapted to seasonally dry tropical climates. The plant has a distinctive columnar shape and produces large, white, night-blooming flowers. It is often used as a natural fence in its native habitat.
Cereus jamacaru thrives in bright, direct sunlight and prefers warm temperatures. It can tolerate low humidity and requires minimal watering, making it ideal for dry climates. Ensure the plant is placed in a well-ventilated area to prevent fungal infections.
土壤
This cactus prefers sandy soil with excellent drainage. A cactus or succulent potting mix is ideal. Avoid using heavy soils that retain moisture, as this can lead to root rot.
肥料
Fertilize Cereus jamacaru with a balanced cactus fertilizer, such as a 5-10-10 formula, during the growing season. Apply the fertilizer sparingly, about once a month, to avoid over-fertilization.
换盆
Repot the plant every 2-3 years or when it outgrows its current pot. Use a pot with drainage holes and fresh cactus soil. Handle the plant carefully to avoid damaging its roots and spines.
传播
Cereus jamacaru can be propagated through stem cuttings. Take cuttings during the growing season, allow them to callous over for a few days, 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 control its size. Pruning is best done during the growing season. Use clean, sharp tools to make clean cuts and avoid introducing infections.
毒性
Cereus jamacaru is not known to be toxic to pets or humans. However, its spines can cause physical injury, so handle with care.
额外的
Cereus jamacaru is a resilient plant that can withstand harsh conditions. It is an excellent choice for xeriscaping and can be used as a natural barrier or ornamental plant in gardens.
