Jasmine (Jasminum polyanthum) is an evergreen vine that is treasured for its fragrant, white flowers. This species of jasmine is often trained on trellises and arbors and is a fast-growing flowering vine, reaching heights of up to 20 feet tall. The flowers are star-shaped and are produced in abundance in midsummer. Its dark green foliage provides a nice backdrop to the fragrant blooms which are attractive to bees and butterflies.

Care Instructions:
Jasminum Polyanthum, commonly known as Jasmine, is a highly fragrant, fast-growing vine known for its clusters of delicate, star-shaped white or pink flowers. This plant is popular for its sweet scent, which fills the air when it blooms, typically in late winter or early spring. With proper care, Jasmine will thrive and bring a delightful aroma and visual appeal to your garden or indoor space.
Light
Jasmine thrives in bright, indirect light to full sun. For optimal flowering, place it in a location where it can receive at least 4-6 hours of sunlight each day. If grown indoors, a bright, south or west-facing window is ideal. While Jasmine can tolerate some shade, too little light may reduce flowering and lead to leggy growth. Ensure the plant receives enough light to maintain its vigorous growth and abundant blooms.
Water
Water your Jasmine regularly, keeping the soil consistently moist but not waterlogged. During the growing season (spring and summer), water more frequently, ensuring the soil remains evenly moist. In the fall and winter, reduce watering slightly, allowing the top inch of soil to dry out between waterings. Jasmine prefers well-draining soil and can suffer from root rot if the soil is too wet.
Soil
Jasmine prefers a well-draining, fertile soil mix. A mix that includes loam, peat moss, and some sand works well, providing the right balance of moisture retention and drainage. If planting in containers, ensure the pot has drainage holes to prevent water from accumulating at the bottom, which can lead to root rot.
Temperature
The optimal temperature range for Jasmine is between 60°F and 75°F (16°C to 24°C). It prefers moderate temperatures and should be protected from cold drafts and temperatures below 40°F (4°C). If grown outdoors in cooler climates, consider bringing the plant indoors or providing frost protection when temperatures drop. Jasmine is typically hardy in USDA zones 8-11.
Humidity
Jasmine enjoys moderate to high humidity levels, ideally around 50-60%. If grown indoors in a dry environment, consider misting the plant occasionally or placing it on a humidity tray. Higher humidity levels help maintain the vibrancy of the foliage and encourage healthy growth and flowering.
Fertilizer
Feed your Jasmine with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season (spring through early fall). Regular feeding encourages healthy growth and abundant blooms. Reduce feeding in the fall and winter when the plant’s growth naturally slows down. Avoid over-fertilizing, as it can lead to lush foliage at the expense of flowers.
Best Placement Ideas
- Trellises and Arbors: Jasmine is perfect for training on trellises, arbors, or pergolas, where its climbing vines and fragrant flowers can create a stunning vertical display. Place them in a sunny location with well-draining soil.
- Fences and Walls: Jasmine can be grown along fences or walls, providing a lush, flowering screen. Ensure they receive enough sunlight and have a sturdy support structure to climb.
- Containers: Jasmine can also be grown in large containers, making them suitable for patios, balconies, or indoor spaces. Use a well-draining potting mix and provide a trellis or support for the vines to climb.
Common Issues
Pests: Jasmine can attract pests such as aphids, spider mites, and whiteflies. Regularly inspect the leaves for any signs of pests, such as sticky residue, webbing, or small insects. Treat infestations promptly with insecticidal soap or neem oil to prevent them from spreading.
Diseases: Overwatering or poor air circulation can lead to fungal diseases, such as powdery mildew or root rot. Ensure the soil is well-draining and avoid letting the plant sit in water. If you notice discolored leaves or a fuzzy growth on the leaves, it may indicate a fungal issue. Improve air circulation and avoid overhead watering to reduce the risk of fungal infections.
Things to Watch Out For
Watch for signs of stress, such as yellowing or wilting leaves, which may indicate improper watering, low humidity, or inadequate light. If the plant’s growth slows or the flowers start to fade, consider adjusting its care routine to better meet its needs. Regularly check the plant’s environment to ensure it remains healthy and vibrant.
Propagation Tips
Propagation Method: Jasmine can be propagated through stem cuttings or layering. For stem cuttings, take a cutting about 4-6 inches long from a healthy stem, remove the lower leaves, and place the cutting in water or directly into moist, well-draining soil. If propagating by layering, bend a healthy stem to the ground and cover a portion with soil, allowing it to root while still attached to the parent plant.
Best Time to Propagate: The best time to propagate Jasmine is in the spring or early summer when the plant is actively growing. This timing allows the new plants to establish roots and grow during the active growing season.
Maintenance Tips
Pruning: Pruning your Jasmine involves removing any dead, yellowing, or damaged leaves and spent flowers to maintain its appearance and encourage continuous blooming. Regular pruning also helps control the plant’s size and shape, especially if grown on a trellis or other support structure. Use clean, sharp scissors or pruning shears to avoid damaging the plant.
Repotting: Jasmine grown in containers should be repotted every 1-2 years or when it outgrows its current pot. Choose a slightly larger pot with fresh, well-draining soil. Repotting is best done in early spring to give the plant time to adjust before the growing season.
