The lovely, aromatic fragrance of Chinese jasmine (Jasminum polyanthum) isn't restricted to fancy perfumes only. The white flowers of this winter-blooming climber exude the same delicious scent in decorative indoor pots and in gardens in U.S. Department of Agriculture cold hardiness zones 8 to 11. A vigorous native of Southeast Asia and one of the few jasmine varieties suitable for a houseplant environment, Chinese jasmine grows up to 20 feet in height, taking over garden walls, fences, arbors and trellises.
1. Indoor Chinese Jasmine
1 Expose jasmine plants to at least 4 hours of sunlight each day during the growing season. In the summer, place the plants outdoors during the day.
2. Indoor Chinese Jasmine
2 Supply jasmine plants with 2 inches of water each week in the spring and summer. In the winter, water the plants only when the soil is dry.

3 Fertilize plants once every two weeks in the spring and summer. Use a high-phosphorus fertilizer at half strength, or a rate of 1/2 tablespoon per gallon of water.

4 Pinch back branch tips in spring to encourage new flowers. After flowering, prune plants aggressively to encourage new growth. Avoid pruning in the late summer or fall.
5. Indoor Chinese Jasmine
5 Repot each plant that outgrows its pot in the spring. Water the plant deeply, then move it to a new, slightly larger pot filled with potting soil. Jasmine does well when slightly rootbound, so too much space can be detrimental. Replant the jasmine at its original depth.
6. Outdoor Chinese Jasmine
1 Keep jasmine plants in garden corners that receive full sun or light shade.
7. Outdoor Chinese Jasmine
2 Water outdoor jasmine moderately, providing 2 inches of water each week if rainfall is insufficient. Increase watering if the plant's leaves begin to wilt. If the plant produces small leaves or shows signs of dieback, water less frequently or improve the soil's drainage with 2 to 3 inches of mulch.
8. Outdoor Chinese Jasmine
3 Prune jasmine regularly throughout the year to prevent overgrowth and tangling vines. Take off dead or diseased branches and leggy growth. Hard-prune to the ground after flowering to rejuvenate the plant.
Items you will need
- High-phosphorus fertilizer
- Pruning shears
- Planting pot (optional)
- Potting soil (optional)
- Mulch (optional)
- Outdoor jasmine does not require regular fertilizing if properly watered, as nutrient deficiency is typically a result of disease and underdeveloped roots from waterlogged soil.
- Always clean your pruning shears with rubbing alcohol or bleach before use on each separate plant to prevent the spread of disease.
- Never water established plants near the trunk, as root rot can set in.
