Choose a hanging basket. Basket options include wire or wooden open baskets and fiber or plastic closed baskets.
Select a hanging site that features a support structure with a hook for the basket. Locate an area with partial shade indoors or indirect sunlight indoors. The ideal temperature for Madagascar jasmine is 70 degrees Fahrenheit during the summer and between 55 and 60 degrees in the winter.
Add 1 inch of gravel to the base of a plastic basket to help with drainage. For wire, wooden or fiber baskets, instead add a basket liner made from fiber or foam. Sphagnum moss is also an option if it includes a polythene lining to prevent dripping.
Fill the basket with a rich, well-drained potting compost. Press the compost down by hand.
Plant the young Madagascar jasmine vine in the center of the basket, at its original depth.
Water the plant thoroughly. Continue watering one to two times per day if not using a basket liner, and half as often if a basket liner is present.
Fertilize the plant six weeks after planting with 1/4 cup of high-potassium liquid fertilizer.
Prune away any weak growth in the late winter with pruning shears. To control the size, cut shoots no shorter than 3 inches in length.
