Erythrina caffra, commonly known as the Coast Coral Tree, is a species of flowering tree in the family Fabaceae. It is native to South Africa and is known for its striking red flowers and thorny branches. The tree can grow up to 30 feet tall and is often used as an ornamental plant in gardens and parks. It has a dormancy period during the winter months.
Erythrina caffra requires bright, direct sunlight for optimal growth. It thrives in moderate temperatures and prefers a humid environment. Water the plant when the soil is almost completely dry, but avoid waterlogging. The plant can tolerate some drought but performs best with regular watering.
土壤
The Coast Coral Tree prefers well-draining loamy soil. Ensure the soil mix allows for good drainage to prevent root rot. A slightly acidic to neutral pH is ideal for this plant.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season, typically in spring and summer, to promote healthy growth and flowering.
换盆
Repot the plant when it outgrows its current container, usually every 2-3 years. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repotting is best done in the spring.
传播
Erythrina caffra can be propagated from seeds or cuttings. For seed propagation, soak the seeds in water for 24 hours before planting. For cuttings, take a healthy branch and plant it in well-draining soil. Propagation is best done in the spring or early summer.
修剪
Pruning is required to maintain the shape and health of the plant. Prune the tree in late winter or early spring before new growth begins. Remove any dead or diseased branches and shape the tree as desired.
毒性
Erythrina caffra is toxic to pets and humans. All parts of the plant contain toxic compounds that can cause symptoms such as nausea, vomiting, and diarrhea if ingested. Handle the plant with care and keep it out of reach of children and pets.
