Selecting the proper segment of the plant is vital for successful propagation. Ideally, the cutting should be taken in the late summer or early fall. This is after the fastest plant growth during the spring and early summer. Cut a 6- to 8-inch section at the end of a stem of this year's growth. Look for a segment of the plant that shows full sized leaves and clip off any flower buds present.
Roots develop best in a high humidity environment. Rooting a few cuttings requires a flower pot filled with coarse sand. Place the cutting about one-third of the way into the sand. Place a plastic bag or other covering over the pot to retain humidity. Build a wood frame, filled with potting soil and covered with plastic, for larger numbers of cuttings. Temperature and humidity control are necessary during the rooting process. Jasmine prefers temperatures between 50 and 55 degrees Fahrenheit at night, and between 68 and 72 F during the day.
Cuttings taken in the late summer and early fall can be transplanted into pots after they establish roots. Replant the jasmine into the landscape, if desired, in the spring. This allows the plant to gain some size before planting into the yard or garden.
Container grown jasmine can be planted outside in the fall, as soon as it has developed roots. Plant the rooted jasmine in an area that will receive at least partial if not full sunshine. The plant prefers a warm area such as the south sides of fences or buildings. Plant the jasmine about 8 feet apart to create borders or hedges.
