Gardenia breeding skills:
First, the soil: Gardenia is an indicator plant of acidic soil, so the slightly acidic environment of the soil is the key to determine the growth of gardenia. The cultivated soil is made up of 70% of sandy soil red soil and 10% of humus leafy. It is preferred to control the pH of the soil between 4.0 and 6.5.
Second, the temperature : Gardenia optimal growth temperature is 16 ° C -18 ° C. The temperature is too low and the direct sunlight is extremely unfavorable for its growth. Therefore, in summer, the gardenia should be placed under the sparse forest or under the shed where the ventilation is good, the air humidity is high and the light is transmitted. In the winter, the environment where the sun is shining and the temperature is not lower than 0 °C is allowed to sleep. If the temperature is too high, it will affect the flowering in the coming year.
Third, moisture : Gardenia flowers like air humid, the growth period should increase the amount of watering. Usually the potting soil is white and can be watered and poured once. It is hot in summer and must be sprayed 2 times to 3 times a day to increase the humidity of the air and help the plants cool down. However, after the flower is bud, the watering should not be too much, so as not to cause the falling bud. Watering in winter is better to prevent dryness.
4. Fertilizer : Gardenia is a plant that prefers fertilizer. In order to meet the demand for fertilizer in the growing season and maintain the slightly acidic environment of the soil, the ferrous sulfate can be mixed into the fertilizer solution for fermentation. After entering the growing season in April, you can topdress once every half month (it is better to use more water when fertilizing to prevent burning). This can not only meet the demand of fertilizer for gardenia, but also maintain the soil environment in a relatively balanced micro-acid environment to prevent the occurrence of yellowing disease, while avoiding the assault of ferrous sulfate, local peracid on gardenia hurt.
