Getting a bigger pot will allow your Gardenia the space it needs to grow.
Don’t stand your pot in a trough or saucer as doing this can retain water, which makes the roots remain wet.
Alternately, get a shallow tray that is wider than the pot. Put some stones or gravel in the tray and add water. The water should not reach the top of the stones and should not touch the plant pot. Stand the Gardenia pot on the stones. The bottom of the pot must not touch water. Keep the water topped up as the moisture will evaporate providing some humidity for the plant above.
Move the pot indoors in zone 7 (where temperatures reach 0- or 5-degrees Fahrenheit, or -17. 8 to -15 degrees Celsius).
If the house is below 60 degrees Fahrenheit (15. 5 degrees Celsius), Gardenias can tolerate some shade or darkness. They’ll stand temperatures that drop down to about 35 degrees F (1. 6 degrees C) in the shade but won’t enjoy going below 20 degrees F (-6. 6 degrees C).
For example, when moving a plant outdoors, put it outside during the day but move it back indoors at night for two to three weeks before leaving it out all day and night.
Try to water with rainwater rather than tap water, if possible. Usually, you should water your gardenias once or twice a week, especially when it’s hot. [6] X Expert Source Andi XochPlant Specialist Expert Interview. 4 August 2021.
Try to use a fertilizer for acid-loving plants, which you can purchase at your local supply store.
If you are really struggling to grow Gardenias the local climate may not be right for them, either indoors or out.
If the plant has too little water, you’ll see the leaves turn brown at the tips.
Mist your plant several times a day until the plant recovers.
Light materials include plastic (you can put the ugly plastic pot inside a more attractive pot). You could also put your pot on a pot trolley to make heavier pots easier to move.
Zone 6 temperatures can drop down to -10 degrees Fahrenheit (-23. 3 degrees Celsius). [9] X Research source
