Jasmine serves as a delightful house plant, and in spite of its exotic appearance, it's easy to grow as long as it receives adequate water and light. In autumn, provide the jasmine plant with a few weeks of dark and cold, and snowy white, star-shaped blooms will burst out in mid-winter, accompanied by a heady, sweet scent.
Locate the jasmine plant where it will receive bright, filtered light at least six hours every day. Don't put the plant directly in a window.
Make a pebble tray for the jasmine plant. Put a few pebbles or stones in a shallow plate or tray and pour fresh water over the pebbles. Set the jasmine plant pot on the pebbles, but don't let the water level touch the bottom of the pot. This increases the humidity in the air around the jasmine plant. Keep the jasmine plant away from wood stoves, heat vents and radiators.
Water the jasmine plant when the top 1/2 inch of the soil feels dry. Don't let the soil get soggy, and never let the pot sit in water. Water the jasmine plant sparingly during the winter.
Feed jasmine twice a month between spring and early fall, using a water-soluble houseplant fertilizer mixed at half strength. Don't fertilize the jasmine plant during the winter months.
Prune the jasmine plant as needed to maintain the desired shape. Never prune the plant after August 1, as the plant will be preparing to bud.
Encourage the jasmine plant to bloom by putting it in a cool room at night for four to five weeks beginning in early September. The plant should get plenty of sunlight during the day, but during the night, move it to a pitch-dark room where the temperature is between 40 and 50 degrees F. After four to five weeks, leave the plant in its regular, daytime location. The plant should bloom in mid-winter.
