Growing Gardenias Indoors: A Guide to Success

Spirit Lake Garden Center: Growing Gardenias Indoors: A Guide to Success

One modest point to take away from cultivating gardenias inside is that you can’t please everyone. Gardenia category, often known as the flowering jasmine, is a beautiful plant with lush, green leaves and delicate, white or yellow flowers. Flowers hanging in a water bowl make a stunning decoration for a table in a conservatory or small apartment. Moreover, the aroma! Even though it may be snowing outside, those flowers emit a luscious aroma that will transport you to a tropical paradise. In this article, I will give some tips and warnings that will increase your chances of success when growing a gardenia species suited to growing in pots.

Indoor cultivation conditions suitability

Growing them indoors exclusively requires the same care as growing them outside, with a few modifications to enable them to thrive in the confines of planters and the drier air.


While lowering the heat at nighttime to let your plants sleep is recommended, you shouldn’t subject them to drastic thermal stress. Store the pots in a cool, dark place (about 60 ° F at nighttime and between 70 and 75 Fahrenheit during the day). If the warmth in a room fluctuates by more than a few degrees throughout the day, or if it is particularly drafty, you should try to find somewhere else to spend your time.


You’ll face this challenge when cultivating these stunning plants outside and inside. A minimum of 4 to 5 hours of direct sun per day is required. However, they wilt under intense sunlight. The best location enjoys early sun and midday shade. To do this indoors, position the flowers on or along a south- or west-facing ledge.

Hydrology and Topsoil

Indoor G. jasminoides cultivation relies heavily on adequate drainage. For optimal drain and hydration retention, choose a medium that has been amended with ample manure and a container with at minimum one vent hole in the bottom. Put a drainage-equipped planter inside a decorative one, with a shovel in between to collect runoff if necessary; this works in the same way if the decorative container lacks drainage holes. Soil pH between 5.0 and 6.0 is ideal for these acid-loving plants.


Indoor gardenias require much moisture, especially if you want them to flower. They like to keep it at a 50/50 ratio! You can spritz them with regular water, but putting a tray of damp pebbles or sand under each container is better. In the cold, whenever the heat is still on, the air in your household may become quite dry, so you might also want to use a dehumidifier. Although any unit you have had on hand will do the trick, it’s best to use one that includes a schedule and a moisture setting of at least 50% to ensure the most accurate results.

Conclusion: Gardenias are often considered aesthetically pleasing blooming shrubs due to their graceful, white blossoms and enticing fragrance.
