Gardenia mostly grows in the south, and the soil in the south is generally acid, so Gardenia likes acid soil. However, when Gardenia moved to the north where the soil acidity was not high, the soil conditions could not create a suitable growth environment for gardenia, so the growth trend would be weakened. And the south is rainy, the air humidity is high, the north air is dry, can't provide enough water vapor for it, so the Gardenia maintenance is not good
Many people choose to water plants directly with tap water, which is actually the direct reason why they can't keep them well. The nature of tap water belongs to hard water, in which there are more fluorine chloride compounds and calcium magnesium compounds. If it is directly used to water flowers, it will gradually deposit lime in the soil. After a long time, the basin soil will be alkaline, which makes the most taboo alkaline soil environment of gardenia, resulting in its growth at a disadvantage.
(1) the soil for cultivating it should be carefully selected. The best choice is to mix 70% of the slightly acid sandy red soil with 30% of the rotten leaves. For acid control, the pH of the soil should be within 4.0 to 6.5 at any time, and ferrous sulfate can be used every three weeks to improve the acidity.
(2) before watering the Gardenia with water, it is necessary to put the tap water in the sun for 2 to 3 days, and then use it after chlorine and other substances evaporate, or directly use rainwater to water the gardenia. In addition, to properly increase the humidity of the air, spray 2 or 3 times a day to the leaves, which can help plants cool down and increase humidity.
