According to the different seasons, the method of watering gardenia is also different. In spring, water it once every three days or so. In summer, it's best to water it once a day because of the hot weather. You can choose to water it in the afternoon. In autumn, it's best to water it once every two days. In winter, you need to control the watering, and wait until the soil is dry.
Because it likes acid soil, so it's best to use rainwater when watering. If it's watering with tap water, add a little white vinegar or citric acid to the water, which can make the soil more acidic and make it grow more healthy.
