Although pink jasmine (Jasminum polyanthum) makes a lovely outdoor plant in warmer climates, it is especially well-suited as a container plant. Leave pink jasmine outdoors on a patio in warm weather, and bring it in before the weather turns cold, or enjoy its beauty indoors all year long. The vine will brighten up midwinter days with pink buds, followed by fragrant white flowers. The glossy foliage will stay bright green all year.
Put the pink jasmine in a cool room, with temperatures between 40 and 50 degrees F, in September, and leave it there until the plant develops buds, which usually takes four to six weeks. Water the pink jasmine sparingly during this time, and don't give it any fertilizer.
Bring the pink jasmine into regular room temperature when it has buds, and put it where it will be in bright light for a minimum of four hours every day. If you live in a climate with low light, or if you don't have sunny windows, supplement the available light with a grow light.
Provide a trellis or other support for the pink jasmine to climb on. Pink jasmine is a vigorous climber, so install the trellis when the plant is young to avoid damaging the plant's growing roots.
Water pink jasmine regularly using room-temperature water. Keep the potting mixture damp but not soggy, and never let the pot sit in water. Mist the plant often with a spray bottle during the winter months.
Fertilize pink jasmine every two to three weeks during spring and summer. Use a fertilizer formulated for tomatoes, which will have enough phosphorus to produce healthy blooms.
Prune pink jasmine after it's finished blooming in spring, using sharp, clean pruners. Pruning the jasmine down to one-third of its size will promote healthy, manageable growth. Remove any weak or damaged shoots and any that are growing inward instead of up and out.
Repot pink jasmine every two to three years. Move it into a container one size larger, filled with commercial potting soil. Be sure the container has good drainage in the bottom.
