Morning star jasmine, also called star jasmine or confederate jasmine, is a flowering woody vine with evergreen leaves. The star jasmine is a popular perennial due to its showy, fragrant white flowers that are about ¾ inches wide and emerge in early spring. The star jasmine is grown outdoors in warmer climates or indoors in colder climates. If you’re growing the plant outdoors, you can plant it next to a trellis, wall or fence to allow it to climb.
Plant your star jasmine in an outdoor location that has moist but well-draining soil and receives full sunlight. If you’re planting the star jasmine in a container, select a 10-inch planter pot with drainage holes in the bottom and fill it with all-purpose potting soil.
Dig a planting hole that is 1 ½ times the width of and the same depth as the nursery container. Work into the soil a dose of slow-release 10-10-10 NPK (Nitrogen-Phosphorous-Potassium) fertilizer. You can also add some organic compost or aged manure to the planting hole.
Remove the root ball from the nursery container gently and carefully loosen the outer roots. Place the star jasmine standing upright in the planting hole, backfill the hole with soil and water the soil to remove any air pockets around the roots.
Water your star jasmine once every two weeks to supplement rainfall, or once or twice each week if the plant is growing indoors. Feed your star jasmine a 10-10-10 NPK fertilizer once per month during early spring through fall, following the application instructions on the package.
Place a drip tray filled with pea gravel and water beneath the planter pot to create humidity for the container-grown star jasmine. Ensure that the pot is resting on top of the gravel and not in the water.
Reduce watering frequency in the fall. Stop watering the plant in winter, unless you’re keeping it indoors in a pot.
Trim and pinch back the stem tips on your star jasmine to control its vigorous growth and to induce a bush shape for a container-grown plant. Prune away all tangled or dead stems after the plant is finished blooming. Snip back the new growth on the stems and head back the vine for a bushier form.
