Why do gardenia leaves turn yellow?
This article provides a detailed explanation for netizens who are concerned about why gardenia leaves turn yellow and offers tips on how to solve the yellowing leaf problem, as follows:
Gardenias are one of the most common plants in homes, with broad leaves, dark green and glossy foliage, graceful flowers, and pure white petals, giving off a fresh and natural feeling. However, it is easy for the leaves to turn yellow during the cultivation of gardenias. What exactly is the reason?
Soil is too alkaline
Gardenias prefer to grow in acidic soil. If the soil is alkaline, the leaves of the gardenia will turn yellow, which is very detrimental to its growth. You can mix vinegar with water in a 1:20 ratio, stir well, and pour it directly into the soil. By watering once every 10 days or so, you can effectively adjust the soil's pH, making the leaves greener and more glossy.
Too much sunlight
Gardenias enjoy sunlight but can also tolerate some shade. They are usually kept in sunny locations during cultivation. However, with high temperatures in summer and strong sunlight, they can easily get sunburned, leading to yellowing and falling leaves. Therefore, during the strong sunlight in summer, it's best to provide some shade.
Overwatering
Gardenias do not require a lot of sunlight. If watered too frequently, it can easily cause the roots to rot, leading to yellowing leaves. You will need to move it to a well-ventilated area to allow the water to evaporate quickly, which will gradually restore its vitality. When watering in the future, you can wait until the soil is slightly dry before watering thoroughly.
Over-fertilization
If the fertilizer concentration is too high during the cultivation of gardenias, it can also cause older leaves to turn yellow and fall, while new leaves become thick and lack luster. You will need to move it to a well-ventilated area and water until it flows out, which can reduce the nutrients in the soil and gradually restore its vitality.
