Many friends think that gardenias like sunshine. Once winter is over, they will move it outside to put it in full contact with the sun. Although this is correct, it needs to be covered properly when the temperature is rising and the sun is getting hotter. The flowering period of this plant is from May to July, just in time for summer, so it's best to put it in a semi shaded place at this time, to block the sunshine around noon, otherwise the newly opened flowers are easy to be early withered by the strong summer light.
Do not over water during the flowering period, let alone water in the basin. Before watering, you can observe the soil. If the surface layer is dry, you can water it. Otherwise, you can't.
Temperature is also one of the factors to prolong flowering. Most suitable for its temperature is 16 degrees to 18 degrees, so the flower period to choose the appropriate temperature of the place to place, if the temperature is too high, you can also artificially cool.
Do not spray water on the plant during the flowering period. Once water drops are produced in the flower center, it is very easy to rot and cause early thanks. But at this time, you can spray more water around the plant. First, you can reduce the temperature. Second, you can improve the humidity of the environment, which is conducive to the growth of flowers and the extension of flower time.
Nutrients are also more important. In its growth period, it should be fertilized every half a month. When the flower bud appears, it should add another one to two times of P and K fertilizer. But it should be noted that if the nitrogen fertilizer is applied too much, it will easily lead to bud falling.
