Everything it needs
9 essentials at a glance
Watering
Jasminum sambac prefers consistently moist soil but should not be waterlogged.
Water when the top inch of soil feels dry, typically every 5-7 days in warmer months and every 10-14 days in cooler months. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in full sun to partial shade, ideally receiving 6-8 hours of direct sunlight daily.
It can tolerate some shade but may produce fewer flowers. For optimal growth, place it in a south or west-facing location where it can soak up the sun.
Soil
Jasminum sambac prefers well-draining, loamy soil with a pH range of 6.0 to 7.0.
A recommended potting mix includes a blend of potting soil, perlite, and peat moss to ensure good drainage and aeration.
Humidity
This plant enjoys high humidity levels of 50-70%.
To increase humidity, mist the leaves regularly or place a humidifier nearby. Signs of low humidity stress include browning leaf tips and leaf drop.
Temperature
Ideal temperature range for Jasminum sambac is between 65-80°F (18-27°C).
It is hardy in USDA zones 9-11. Protect it from temperatures below 50°F (10°C) and avoid extreme heat above 90°F (32°C) to prevent stress.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or 20-20-20.
Fertilize every 4-6 weeks during the growing season (spring and summer) and reduce frequency in fall and winter. Signs of nutrient deficiency include yellowing leaves and poor growth.
Pruning
Prune Jasminum sambac in late winter or early spring to encourage bushy growth and flowering.
Use clean, sharp pruning shears to remove dead or weak stems and shape the plant. Deadheading spent flowers can promote further blooming.
Repotting
Repot every 2-3 years or when the roots outgrow the pot, indicated by roots growing out of the drainage holes.
Choose a pot 1-2 inches larger in diameter. Carefully remove the plant, loosen the roots, and place it in fresh potting mix, ensuring the root ball is at the same depth as before.
Propagation
Jasminum sambac can be propagated through stem cuttings or layering.
For stem cuttings, take 4-6 inch cuttings from healthy stems in spring or early summer, remove lower leaves, dip in rooting hormone, and plant in moist potting mix. Keep the soil moist and place in indirect light until roots develop, usually within 4-6 weeks.
