Following is the empirical care for all Jasminum sambac varieties :
Temperature: Thrive well between roughly 18 to 25 C . In Canada whenever lowest temperature falls below 15 C this plant need to be brought indoor
Light: Jasminum sambac thrives in bright indirect light to full sun. It is not suited for low light conditions. South or West windows are ideal. East windows may work but lack of direct sunlight can inhibit flowering. Consider addiing artificial light / grow lights if your home doesn’t provide enough sunlight. When kept outdoor during late spring / summer please watch if plant leaves are getting burnt as UV index in Canada is high. If required can cut off light to required proportion with help of shade cloths.
Water: Water every 1-2 weeks allowing potting mix or soil to dry out about halfway down between watering. Expect to water more often in brighter light conditions.
Humidity in the Air: Jasminum sambac can tolerate normal room humidity but will benefit from high humidity and produce more flowers. If the air in your home is usually dry and arid, which happens often in Canadian indoor due to furnace / AC run, consider boosting humidity in the air by running humidifier or any innovative way.
Soil: Allow your Jasmine Sambac to acclimate for about two weeks before you consider potting or repotting. Any good quality, well draining potting mix can be used. For Canadian indoor use mixing proper level of Perlite works better. Contact Sikdar Gardens for ready best quality soil.
Fertilization: During its rapid growth phase eg in summer can be fertilized with Sustained release fertilizer to suppliment soil nutritional value for the plant. Contact Sikdar Gardens for SRF.
