1、 Wrong water and fertilizer

The normal growth and smooth flowering of Gardenia are inseparable from the application of water and fertilizer. If it only grows leaves without flowering, it may be because this aspect is wrong.

Normal fertilization can be carried out before and after flowering to reduce nitrogen and increase phosphorus and potassium

2、 The temperature is too high

During winter maintenance, the indoor temperature is too high, which will make it germinate early. In this way, it is difficult to form flower buds, grow flower buds and bloom. If the indoor temperature is too high, you can put it on the balcony

Flowering has a lot to do with the supplement of sunlight. If the light is insufficient, it will be difficult for plants to bloom. According to the changes of seasons, appropriate sunshine can be given. Pay attention to shade in summer and avoid sunshine. In winter, sunshine can be supplemented and exposed to full-time sunshine

4、 No pruning
