Gardenia in hydroponics is the same as Gardenia in soil culture. It has a high demand for light. It needs to be able to receive a certain amount of natural light every day, because it doesn't like strong light, so in addition to shading it at noon when the sun is big, it doesn't need to do special treatment at other times, so it can be irradiated normally.
The plants in hydroponic culture need to change water frequently, so as to ensure its vigorous vitality. When changing water, it is necessary to add nutrient solution to its water, because gardenia is a fertilizer loving plant, it is difficult to meet the needs of Gardenia only by the nutrients in water. The water for Gardenia also pays attention to. There is chlorine in the tap water, which will affect the growth of plants. Therefore, the water for Gardenia can't be fresh tap water. It's better to air the water for three or four days naturally. When the water is in the air, the chlorine in it is released, which is not harmful to plants.
Water culture Gardenia does not need to add water to the culture vessel, just need to spray water on its branches and leaves every morning and night, in order to give it a warm growing environment.
Gardenia in hydroponics is also to be pruned. The purpose of pruning is the same as that of Gardenia in soil culture, which is to make nutrients more concentrated and help it produce more flowers with good quality. When pruning, you only need to cut off the dead branches and rotten leaves to make room for the healthy branches to blossom in the future.
