Rosa foetida, commonly known as the Austrian Copper Rose or Persian Yellow Rose, is a species of rose native to the Caucasus Mountains and northern Iran. It is known for its vibrant yellow flowers and strong fragrance. This deciduous shrub typically goes dormant in the winter months.
Rosa foetida requires bright, direct sunlight for optimal growth. It thrives in moderate temperatures and prefers a moderate level of humidity. Regular watering is essential, but the soil should be allowed to dry out partially between waterings. This plant is best suited for outdoor growth.
土壌
Rosa foetida prefers well-draining loam soil with a slightly acidic to neutral pH. Good drainage is crucial to prevent root rot. A mix of garden soil with compost or well-rotted manure can provide the necessary nutrients.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-5. Fertilize the plant in early spring and again in mid-summer to promote healthy growth and flowering.
植え替え
Repotting is generally not required for Rosa foetida as it is typically grown outdoors. However, if grown in a container, repot every 2-3 years in early spring before new growth begins. Ensure the new pot has good drainage.
伝搬
Rosa foetida can be propagated through hardwood cuttings taken in late autumn or early winter. Plant the cuttings in a well-draining soil mix and keep them in a sheltered location until they root.
剪定
Pruning is essential for maintaining the shape and health of Rosa foetida. Prune in late winter or early spring before new growth starts. Remove dead or diseased wood and thin out crowded branches to improve air circulation.
毒性
Rosa foetida is not known to be toxic to pets or humans. However, the thorns can cause physical injury, so handle with care.
追加
Rosa foetida is known for its resistance to some common rose diseases, but it can be susceptible to black spot and powdery mildew. Regular monitoring and appropriate fungicide treatments can help manage these issues.
