Pink jasmine is an evergreen vine that produces pink-white fragrant flowers. The flowers bloom in the late winter through early spring and occasionally at other times of the year. Pink jasmine, Jasminum polyanthum, is also know as winter jasmine or Chinese evergreen jasmine as it is native to China. The woody trailer vine will climb up to 20 feet in height, if given support. You can also train pink jasmine into a bushy shrub, with proper care and pruning.
Plant the pink jasmine plant outdoors in an area that receives at least four hours of direct sunlight and has well-drained soil. Indoors, the plant will thrive in a quality potting soil that retains moisture yet drains well.
Dig a hole that is slightly larger than the pot. Fill the bottom of the hole with compost, remove the plant from the pot, and place in the hole. Fill the hole the remaining soil and compost and gently pack in place.
Water the plant immediately after planting and continue to keep the soil moist but not wet. Be careful if using rainwater, as it may be acidic. Use warm water when possible. Water the plant only when the soil dries in the winter months, as less water is needed.
Mist indoor and outdoor jasmine plants with warm, lime-free water to increase humidity around the plants. Lime in water will form spots on the leaves.
Fertilize the plants every two weeks with a high phosphorous fertilizer such as 15-30-15. This will encourage the plant to bloom.
Bring outdoor jasmine plants inside when the night temperature reaches 40 degrees F. The buds should be set at this time and will bloom when placed in a sunny but cool location.
Prune jasmine plants by cutting back the plant after blooming and in the summer months when the growth becomes vigorous.
Repot jasmine plants every two to three years in a pot that is 1 to 2 times larger in size. The best time to repot is in the spring, after flowering.
Propagate new plants by taking stem cuttings in the spring. Place the cutting in an even mixture of perlite and moist peat. Secure a plastic bag over the pot and bind with string or a rubber band to prevent moisture escape. Set the pot under grow lights or indirect sunlight to start root growth.
