The reasons why most plants do not grow well are related to the environment. Gardenias generally grow in the south and like acidic soil. The south has more rain and high humidity, so when gardenias come to the north, the humidity suddenly drops. , the pH of the cultivated pot soil cannot reach between 4 and 6.5, which will cause it to grow poorly. In addition, water quality is also an important reason. If tap water is used for irrigation for a long time, the content of fluorochloride and calcium and magnesium compounds in the water will be high. , naturally it will not be possible to grow gardenias well.

1. Reasons

(1) Unsuitable maintenance conditions

Gardenias mostly grow in the south. The soil in the south is generally acidic, so gardenias like acidic soil. soil. When gardenias are moved to the north where the soil acidity is not high, the soil conditions cannot create a suitable growth environment for gardenias, so their growth will gradually weaken. Moreover, it is rainy in the south and the air humidity is high, while the air in the north is dry and cannot provide sufficient water vapor, so gardenias cannot be maintained well.

(2) Water quality

Many people choose to water their plants directly with tap water. In fact, this is the direct reason why they cannot grow them well. Tap water is hard water and contains a lot of fluorochlorine compounds and calcium and magnesium compounds. If it is used directly to water flowers, lime will gradually be deposited in the soil. After a long time, the pot soil will become alkaline, which creates the appearance of gardenias. The most taboo alkaline soil environment causes its growth to be at a disadvantage.

2. Solutions

(1) The soil for cultivating it must be carefully selected. It is best to use slightly acidic sandy red soil mixed with 70% and 30% leaf humus. To control the acidity, the pH of the soil should be within 4.0 to 6.5 at all times. Use ferrous sulfate every three weeks to increase acidity.

(2) Before watering gardenias, you need to put the tap water in the sun for 2 to 3 days and wait for chlorine and other substances to evaporate before using it, or use rainwater to water the flowers directly. In addition, to appropriately increase the humidity of the air, you can spray the leaves 2 or 3 times a day, which can not only help the plants cool down, but also increase the humidity.
