The jasmine houseplant will thrive and blossom as long as it is cared for properly. The plant produces small white flowers in the shape of a star, but only if it has the correct light, watering schedule, fertilizer and pruning to keep it healthy. This type of plant does very well indoors, but the temperature must be correct. Keeping the jasmine in an area where the temperatures are too warm or cold will affect the plant's ability to flower.
Place the plant in a room with a temperature of 65 degrees F or less. If the room temperature is any warmer, the plant will not flower.
Place the jasmine where it will have enough light, but no direct sunlight. Place the plant in a north window or in an east window with filtered light. Once the plant flowers, it needs six hours of sunlight a day at normal room temperatures. Set the plant outside during the summer, alternating between shade and full sun.
Water the jasmine when the soil is dry to the touch, but not completely dry to the bottom of the pot. Stick your finger 1 inch down in the soil and water when the soil feels dry. The plant does not tolerate soggy soil. If the watering is done correctly, the plant will flower in January or early in February. Keep gravel in the drainage tray to catch runoff water, which helps humidify the plant.
Prune as desired. Pruning is done to keep the houseplant manageable or shaped, but is not necessary otherwise. However, plants cannot be pruned after August 1.
Fertilize the plant only after it blooms. The plant needs fertilizer every two to four weeks during the growing season, which is early spring until fall. During the winter and fall months, do not give the plant fertilizer. Note: When you use a houseplant fertilizer, only use half of the amount recommended on the package.
Keep the plant in a cool room with temperatures between 40 and 50 degrees F for four to six weeks during autumn with sunlight. During the winter, keep the plant in the cooler temperatures, but no direct sunlight until the plant blooms toward the end of winter.
