Prepare a rooting container before taking cuttings from the Trachelospermum jasminoides vine. Fill an 8-inch planting container with a thoroughly combined mixture of equal parts garden soil and sharp river sand.
Run water over the soil until it trickles out the drainage holes. Let the pot drain for 10 to 15 minutes, then press the surface of the soil to expel the excess water. Poke a 4-inch-deep planting hole.
Take a cutting from the Trachelospermum jasminoides vine, using a pair of clean, sharp pruning shears. Measure 8 inches from the tip of a leafy, vigorous vine and make the cut at a slight angle.
Pinch off and discard the leaves from the lower 1/2 of the vine, cutting to expose the nodes. Coat the defoliated end of the cutting with 0.5-percent IBA rooting powder.
Insert the base of the Trachelospermum jasminoides cutting into the prepared planting hole. Press the soil around the cutting to ensure it makes complete contact with the flesh of the plant.
Set the planting container outdoors in a warm spot with bright light, but no more than two hours of direct sunlight each day. Water the Trachelospermum jasminoides cutting as needed to keep the soil from drying out.
Check for roots in 15 to 25 days by pulling on the base of the cutting very gently. Roots have formed if the cutting feels sturdy and resists the pulling motion.
Keep the Trachelospermum jasminoides plant in its rooting container for three months, or until it is well established, then plant it in a permanent bed or move it to a larger pot.
