How to Start a Star Jasmine Hedge

Prepare a planting location in sun or partial shade with well-drained and moist soil. Incorporate leaf mold to improve and enrich the soil. If you're growing the plant indoors, choose a spot with bright or partly-filtered light. Star jasmine grows best in temperatures in the 68 to 72 F range during the day, or 50 to 55 F at night.

Dig holes about twice the size of the root balls of your plants, spaced about 20 feet apart. Vines can grow quite extensively, up to 20 feet or more, so they truly need plenty of space.

Provide water to keep the soil evenly moist, especially after transplanting. You can water less often once plants are established, as they're relatively drought-tolerant.

Apply a balanced fertilizer in spring. Yellowing leaves indicate that the plant needs nutrients. An addition of fertilizer will encourage fast growth into a hedge, although star jasmine will grow quickly without any help.

Prune the plant to control and shape its growth by cutting vines back with pruning shears. You can encourage a round, mounding shape with persistent pruning. Cut off any trailing vines that stick out wildly from the intended shape. Pinch the tips of the vines to encourage fuller growth. The ideal time to prune is after the blooms have appeared, which usually occurs in summer, to avoid cutting off potential blossoms.

Provide support to encourage a taller or climbing hedge, if desired. Star jasmine will not climb up a brick wall, but requires some kind of trellis for twining. Providing this structure will result in taller growth and a screening habit.
