Don't take Gardenia outdoors at will. The temperature changes a lot indoors and outdoors in winter. If you take the plant outdoors suddenly, the maintenance environment of Gardenia will suddenly change, which will cause the buds of the plant to fall, or even wither.
If excessive water is applied to the plant when it grows flower buds in winter, resulting in excessive soil moisture or insufficient fertilizer application, it may cause the plant flower buds to fall. In winter, it's best to use some acid nutrient solution to supplement nutrition for plants.
1. The plant should be placed in a place with good indoor sunshine for breeding. It's better to put it on the balcony for regular ventilation. The temperature can be kept slightly moist, and the temperature can't be too low
2. Although the temperature in winter is relatively low, the sunshine is soft and warm, so it can let the plants receive more sunlight on the balcony, which is helpful to eliminate diseases and insect pests, and also conducive to the opening of flowers in the next year.
