The Reasons for the Yellowing of Gardenia Leaves
Compared to the common knowledge about why the leaves of gardenias turn yellow for most people, the following will provide you with some insights.
1. Overwatering: Overwatering gardenias can lead to waterlogging and root rot, which affects the normal transport of nutrients. 2. Intense sunlight: Gardenias exposed to prolonged intense sunlight may lack water, causing the leaves to wither and turn yellow. 3. Insufficient nutrients: Not fertilizing gardenias for a long time. 4. Disease infection: Gardenias affected by leaf spot disease.
The Reasons for the Yellowing of Gardenia Leaves
1. -- Overwatering --
The yellowing of gardenia leaves may be caused by excessive watering. Gardenias have poor flood tolerance. If the soil is not allowed to dry out between waterings, it can lead to waterlogging and root rot, affecting the normal transport of nutrients and causing the leaves to turn yellow.
2. -- Intense Sunlight --
Gardenias need ample sunlight during their growing period to enhance photosynthesis in the leaves. However, it is important to avoid prolonged exposure to intense sunlight, as this can cause yellow spots on the leaves, affecting the healthy development of the plant.
3. -- Insufficient Nutrients --
Gardenias require a certain amount of nutrients for normal growth. If the plant is not supplied with nutrients for a long time, it can easily lead to yellowing and drying of the leaves. It is best to apply a nitrogen-phosphorus-potassium compound fertilizer once a month to the gardenias.
4. -- Disease Infection --
Gardenias are prone to leaf spot disease during their growing period. Once infected, yellow spots will appear on the branches and leaves. If not treated in time, the entire plant can become infected. It is important to promptly remove and destroy the diseased leaves and spray the plant with carbendazim to prevent further infection.
