How to Grow Jasmine Indoors

Jasmine are tender perennials with fragrant flowers that are grown as potted plants. They are one of the easiest flowering plants to grow, and encourage to flower, indoors. Your jasmine plant will continue to thrive and produce flowers much better if you move it outdoors during the summer growing season.

Maintain proper temperatures. During fall and winter, grow jasmine indoors in a room where temperatures remain below 65 degrees Fahrenheit. Exposure to warmer temperatures inhibits the formation of flowers, although the plant will continue to grow leaves. After the plant finishes flowering in late winter, move to a location at normal room temperatures.

Place indoor jasmine plants in bright, indirect light during fall and winter. Place in a window that receives little or no direct sunlight--a north-facing window is best or an east-facing window that receives some shade from outdoor trees or buildings. After your jasmine plant finishes flowering in late winter, move it to a sunny window that gets at least 6 hours of direct sun per day.

Provide high humidity. Run a humidifier in the room where your jasmine is growing. Another way to increase humidity is to place your jasmine plant on a saucer filled with rocks. Add water to the level just below the tops of the rocks, so the pot of jasmine does not sit directly in the water. As the water evaporates it adds humidity to the air around the plant. Continue to provide high humidity during the entire indoor growing season.

Water jasmine when the potting soil feels dry to the touch ½ inch below the surface. Do not over-water; jasmine will not tolerate soggy soil.

Move your jasmine plant outdoors in spring after all danger of frost has past. Put it in the shade and gradually move to a location that gets full sun by putting it in the sun for a longer period each day until it is in full sun all the time.

Fertilize jasmine weekly during the outdoor growing season. Use water soluble fertilizer mixed at half the rate recommended by the manufacturer. Do not fertilize when the potting soil is dry; an ideal time to apply water soluble fertilizer is the day after the plant has been thoroughly watered. Stop fertilizing in early fall and do not begin fertilizing again until the plant is moved outdoors in spring.

Prune jasmine as necessary to shape it or maintain it at a manageable size. Do not prune after August 1; flower buds form in late summer.

Move your jasmine plant indoors before freezing temperatures arrive in your location. Leave it outdoors as long as temperatures remain in the 40s and 50s, as these cooler temperatures are necessary for flower buds to form.
