If winter blooms and sweet, nighttime fragrance appeal to your senses, consider growing jasmine indoors. Not all jasmine flowers are fragrant, but Jasminum polyanthum, the variety commonly used when growing jasmine indoors, has a sweet aroma that is particularly fragrant at night. Let’s learn more about the care of indoor jasmine.
How to Care for a Jasmine Houseplant
Indoor jasmine plants actually benefit from spending time outdoors. In summer, locate indoor jasmine plants in a partly sunny spot to encourage robust growth.
Jasmine flowers are set during another outdoor stretch of six weeks in the cool of autumn. This encourages buds to form for the typical February bloom of jasmine flowers. If indoor jasmine plants don’t bloom, it may be they’ve not been exposed to cool enough temperatures.
Back inside, place near a south window when growing jasmine indoors. Indoor jasmine plants are vigorous climbers and need an indoor trellis or support for their vigorous growth.
Care of Indoor Jasmine
Cool temperatures and the right location in a well lit room or sunny window is important for this plant. Good air circulation helps promote showy white, winter blooms of the J. polyanthum when growing jasmine indoors. The plant can tolerate as much as 4 hours per day of direct sunlight, from late spring through fall. Decrease direct sunlight in winter.
Soil for indoor jasmine plants should be porous and may be modified with bark, coir or other organic materials. The soil mixture should remain moist throughout the year, but not soggy. Less water is needed during the resting period following bloom decline.
Care of indoor jasmine includes fertilization with a weakened houseplant food throughout the growing season. High phosphorus fertilizer prolongs the length of bloom time.
White, cottony masses under leaves and on stems may indicate that mealybugs have taken up residence on your plant. Remove as many as possible when pruning. Use a cotton swab dipped in alcohol to remove any masses left when pruning is finished.
Pruning is necessary when growing jasmine indoors. As you’re learning how to care for a jasmine houseplant, you may find it getting out of hand if you don’t prune regularly to keep it under control. Prune heavily at the beginning of the spring growing season while training the twining vine to a support.
Indoor jasmine plants have a long lifespan when cared for properly. Repot in spring. Prune the roots when moving to fresh soil, as needed.
If you have a different type of jasmine and want to try growing it indoors, follow the above guidelines. Other types may not need as much sun, but often grow equally well and bloom when grown as indoor plants.
