Phaseolus coccineus, commonly known as the scarlet runner bean, is a climbing plant native to the mountains of Central America. It is known for its vibrant red flowers and edible beans. The plant is a perennial in its native habitat but is often grown as an annual in temperate climates.
Scarlet runner beans thrive in full sun and require moderate temperatures. They prefer consistently moist soil and benefit from regular watering. The plant enjoys high humidity and should be protected from frost. Provide a trellis or support for the climbing vines.
收成
Phaseolus coccineus, commonly known as runner beans, should be harvested when the pods are young and tender, typically around 85 days after planting. To harvest, gently pull the pods from the vine, taking care not to damage the plant. Regular harvesting encourages more pod production. For dry beans, allow the pods to mature and dry on the plant before picking. Ensure the beans are fully dry before storing to prevent mold and spoilage.
土壤
Phaseolus coccineus prefers well-draining loamy soil that is rich in organic matter. The soil should be kept evenly moist but not waterlogged. Good drainage is essential to prevent root rot.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize the plant every few weeks during the growing season to promote healthy growth and flowering.
换盆
Repotting is generally not necessary for this plant as it is often grown as an annual. However, if grown in containers, repotting may be needed if the plant outgrows its pot. Repot in the early growing season.
传播
Scarlet runner beans can be easily propagated from seeds. Sow seeds directly in the garden after the last frost date. Seeds can also be started indoors a few weeks before the last frost and transplanted outside.
修剪
Pruning is beneficial to encourage bushier growth and to remove any dead or damaged parts. Prune the plant during the growing season as needed to maintain its shape and health.
毒性
Phaseolus coccineus is not toxic to pets or humans. However, the raw beans contain lectins, which can be harmful if consumed in large quantities. Cooking the beans thoroughly neutralizes the lectins.
额外的
Scarlet runner beans are not only ornamental but also edible. The young pods can be eaten whole, and the mature beans can be dried and stored for later use. The flowers are also edible and can be used in salads.
