Seed Propagation
Cotoneaster acutifolius Turcz. can be propagated from seeds. The ripe seeds should be collected from the plant and sown in a well-draining, nutrient-rich soil. The seeds should be sown in the spring or early summer.
The seeds should be covered with a thin layer of soil and kept moist until germination. Germination usually occurs within 3-4 weeks. Once the seedlings have grown to 2-3 inches tall, they can be transplanted into individual pots or containers.
Cuttings Propagation
Cotoneaster acutifolius Turcz. can also be propagated from cuttings. The cuttings should be taken from a healthy plant in the early summer or late fall. The cuttings should be 6-8 inches long and should be taken from the current year's growth.
The cuttings should be dipped in rooting hormone and planted in a well-draining, nutrient-rich soil. The cuttings should be kept moist and provided with partial shade until they have rooted. Once the cuttings have rooted, they can be transplanted into individual pots or containers.
Layering Propagation
Cotoneaster acutifolius Turcz. can also be propagated using layering. This method involves bending a low-growing branch of the plant to the ground and covering it with soil, leaving the tip of the branch exposed.
The branch should be kept moist and provided with partial shade until roots have developed. Once roots have developed, the branch can be cut away from the parent plant and transplanted into individual pots or containers.
Regardless of the propagation method used, the young plants should be kept in a well-lit, protected area until they have become established.
