1、 Soil

Gardenia is an acidic plant. Acidic soil is more suitable for its growth. Therefore, when raising it, we should often test the pH value of the soil. If the value is greater than 7, it is alkaline. If the soil is acidic, you can change it into alkaline soil. If there is alkaline soil, you can also change it into alkaline soil

2、 Illumination

Gardenia is a semi shade plant, which needs some light. It is necessary to ensure astigmatism irradiation for six hours every day to avoid direct strong light. Direct sunlight will cause its leaves to turn yellow and flower buds to fall, so we must pay attention

3、 Temperature

The temperature suitable for the growth of gardenia is more than 15 degrees and less than 25 degrees. When the temperature is high, move the Gardenia to a cool place, or spray water to cool it. When the temperature is low, pay attention to help it keep warm. If it is potted, you can move it to a warm place. If it is planted outdoors, you can cover the Gardenia with straw and wrap fresh-keeping film to help it keep out the cold

4、 Watering

Gardenia likes wet or waterlogging, so it should be watered more, but the amount of watering should not be too much. It's best to water twice or three times a week. Each watering can't let there be ponding in the basin. Its root system is a meat root. Ponding will affect the root's absorption of nutrients and growth. In addition to watering, spray water on the branches and leaves of Gardenia every morning and evening. The finer the water droplets, the better, which is easy to absorb
