Vinca major, commonly known as greater periwinkle, is a flowering plant in the family Apocynaceae. It is native to the Mediterranean region and is known for its glossy green leaves and violet-blue flowers. It is often used as ground cover due to its vigorous growth and ability to spread quickly.
Vinca major is relatively easy to care for. It prefers bright, indirect light but can tolerate some shade. It thrives in moderate temperatures and average humidity levels. Water the plant when the top layer of soil feels dry, but avoid waterlogging.
土壌
Vinca major prefers well-draining loamy soil. It can tolerate a range of soil types but performs best in soil that retains some moisture without becoming waterlogged. Ensure good drainage to prevent root rot.
肥料
Feed Vinca major with a balanced fertilizer, such as 10-10-10, during the growing season. Fertilize every 4-6 weeks to promote healthy growth and flowering.
植え替え
Repot Vinca major when it outgrows its current container, typically every 1-2 years. Choose a slightly larger pot with good drainage. Gently remove the plant from its old pot, loosen the roots, and place it in the new pot with fresh soil.
伝搬
Vinca major can be propagated through stem cuttings or division. Take cuttings in spring or early summer, dip them in rooting hormone, and plant them in a well-draining soil mix. Keep the soil moist until roots develop.
剪定
Prune Vinca major to control its growth and shape. Trim back any overgrown or leggy stems in early spring. Regular pruning encourages bushier growth and more flowers.
毒性
Vinca major is toxic to pets and humans if ingested. All parts of the plant contain alkaloids that can cause symptoms such as vomiting, diarrhea, and low blood pressure. Keep it out of reach of children and pets.
