Why do newly bought gardenias turn yellow before they finish blooming?

It's gardening season now, and the first choice for flower lovers buying plants at the flower market is the gardenia. But many flower lovers report that the gardenias they just brought home either turn yellow or drop their buds. What exactly is the problem? Let's analyze it for you.
Newly bought gardenias often show drooping leaves, especially large-leaf gardenias. This is because after coming home, the growing environment has changed. Gardenias are all cultivated in greenhouses, where the air humidity is very high. The home environment is different, with lower temperatures and dry air, so this situation occurs.
Because most gardenias are greenhouse seedlings, they naturally react this way without having experienced wind and rain. So the gardenias we newly buy need proper conditioning, otherwise yellow leaves will appear and that's not good. We can use a professional root-promoting nutrient solution to condition the gardenia. This can prevent yellow leaves.
In addition, newly bought gardenias have leaves, new leaves and flower buds that demand a lot of water. The low air humidity at home means the gardenia can only get water from its root system, which increases the burden on the roots, and the new leaves and tender leaves will also wilt and turn yellow.
The solution is: for a newly bought gardenia, water it thoroughly, then use a plastic bag to cover the whole gardenia, and place it in a spot with light. When the temperature is high at noon, open the plastic bag to let it breathe. Once the leaves return to their original state, the bag can be removed.
If you find this troublesome, you can also simply move the gardenia pot to the bathroom, prop it up on something, and sprinkle water around the pot to increase air humidity, but do not let the flower buds get wet. After about 1 week, the gardenia will recover and adapt to the home environment.
If you want to thoroughly solve the yellow leaves of gardenias, there is actually a way. That is to improve the soil, and it must be slightly acidic nutrient soil. Good aeration and high organic matter. Combined with a root-promoting nutrient solution, this can completely solve the yellow leaves.
After the gardenia recovers, its growth process will also need nutrients. A special liquid flower fertilizer for gardenias is very good. After use, the gardenia's new leaves and new shoots grow quickly, and flower buds keep emerging.
