Propagating honeysuckle plants is the act of cutting a branch from an established honeysuckle and attempting to grow a new plant from the branch. When choosing a branch from which to take your cutting, select one that is one year old or younger. The best time to take a cutting is in the late fall or early winter, when the plant is in its dormant stage.
Cut a branch from the upper portion of a healthy honeysuckle plant with a sharp knife. Choose a branch 1/4 to 1 inch in diameter and cut so it is 8 to 10 inches in length.
Place the cutting in a plastic bag. This prevents the cutting from wilting before planting.
Remove the cutting from the plastic bag and immerse the cut end of the cutting into a rooting hormone. You will find this at most gardening centers.
Establishing a Root System
Fill a large 8- to 10-inch pot with a rooting medium. Recommended rooting mediums include coarse, construction-grade sand, grade 2 vermiculite or equal parts of vermiculite and peat moss.
Remove the cutting from the rooting hormone and insert it into the rooting medium, up to the first set of leaves. Water the rooting medium thoroughly to ensure optimum contact between the cutting and rooting medium.
Water the rooting medium often to keep it moist. Place a plastic bag over the cutting and top of the pot to keep the humidity around the cutting high. This acts as a miniature greenhouse.
Pull the cutting out of the rooting medium and inspect the root length after several weeks in the rooting medium. When the cutting has grown roots 1 inch or longer, it is time to transplant the cutting.
Transplanting the Cutting
Fill another 8- to 10-inch pot with equal parts sand, peat moss and topsoil. Add 1 cup of 12-12-12 fertilizer and 2 cups ground limestone to the topsoil mixture and blend all components thoroughly.
Plant the cutting into the growing medium, up to the first set of leaves, and place the pot outside. Place a shade covering over the cutting for the first growing season. Burlap or snow fencing works well.
Place a 2- to 3-inch layer of straw around the base of the cutting, before the first frost, to protect the cutting's roots from cold damage.
Transplant the cutting into its permanent location after the end of the second growing season.
