Plumeria obtusa, commonly known as the Singapore Graveyard Flower or Frangipani, is a species of flowering plant in the family Apocynaceae. Native to the Caribbean, it is widely cultivated in tropical and subtropical regions for its fragrant flowers. The plant can grow as a shrub or small tree and is known for its glossy, dark green leaves and white, fragrant flowers. It typically undergoes a dormancy period during the cooler months.
Plumeria obtusa thrives in bright, direct sunlight and prefers moderate temperatures. It should be watered when the soil is almost completely dry, and it benefits from high humidity. The plant can be grown both indoors and outdoors, but it requires a warm environment to flourish.
土壌
Plumeria obtusa prefers well-draining soil, such as a loam mix. Good drainage is essential to prevent root rot. The soil should be allowed to dry out almost completely between waterings to mimic its natural habitat.
肥料
Use a balanced fertilizer with a higher phosphorus content, such as 10-30-10, to promote flowering. Fertilize the plant every 2-4 weeks during the growing season. Reduce or stop fertilizing during the dormancy period.
植え替え
Repot Plumeria obtusa every 2-3 years or when it outgrows its current pot. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repotting is best done in the spring before the growing season begins.
伝搬
Plumeria obtusa can be propagated through cuttings. Take a cutting from a healthy branch, let it dry for a few days to form a callus, and then plant it in well-draining soil. Keep the soil slightly moist until roots develop.
剪定
Prune Plumeria obtusa to maintain its shape and remove any dead or diseased branches. Pruning is best done in late winter or early spring before new growth begins. Use clean, sharp tools to make clean cuts.
毒性
Plumeria obtusa is toxic to pets and humans if ingested. The sap can cause skin irritation, so it is advisable to wear gloves when handling the plant. All parts of the plant contain toxic compounds.
追加
Plumeria obtusa is known for its beautiful and fragrant flowers, which are often used in leis and other floral arrangements. The plant can be sensitive to cold temperatures, so it should be protected or brought indoors if temperatures drop below 10°C (50°F).
