Propagating Euonymus Radicans Sieb. Ex Miq.
Euonymus Radicans Sieb. ex Miq. is a popular plant that can be propagated by several methods. The plant, also known as creeping Euonymus, can be propagated by cuttings, layering, and division.
Cuttings
Propagation by cuttings is the most common method for Euonymus Radicans Sieb. ex Miq. To propagate the plant, take the stem cuttings from a healthy and mature plant during the summer months. The cutting should be about 10 cm long and have at least two leaf nodes. Remove any leaves that are 2 cm from the base of the cutting, dip the end in rooting hormone and plant it in a well-draining potting soil. Keep the soil moist, and the cutting should root in about 2-3 weeks. Once the roots are established, the cutting can be transplanted into a larger pot or into the ground.
Layering
Propagation by layering is an easy method to propagate Euonymus Radicans Sieb. ex Miq. To propagate by layering, select a long and flexible stem that is touching the ground or can be bent to the ground. Use a sharp knife to make a small cut on the stem's underside where it touches the ground, dust the wound with rooting hormone, and cover the area with soil. Make sure the soil is well-draining and moist. After a few months, roots will develop from the wound, and you can cut the new plant off from the parent plant and transplant it in a pot or in the ground.
Division
Propagation by division is also possible but should be done in the spring or early autumn when the plant is not actively growing. To propagate by division, dig up the entire plant and carefully separate the root ball into smaller sections. Each section should have at least one stem and a few roots. Plant each new section in well-draining soil, water well, and keep the soil moist until the new plants are established.
