What to do if the gardenia leaves turn yellow
This article's core guide: How to deal with yellowing leaves of gardenias and the reasons and solutions for yellowing leaves, follow the editor to see the specific content!
Change the soil: If yellowing is caused by soil stickiness or excessive alkalinity, it is necessary to change to a loose, breathable, slightly acidic soil as soon as possible.
Water properly: If yellowing is caused by prolonged drought due to lack of watering, it is necessary to replenish water immediately, making sure to water thoroughly.
Shield from light promptly: If the leaves are sunburned by strong sunlight, it is necessary to shield from light or move to a shady place as soon as possible.
Control temperature promptly: If the leaves are frostbitten due to low temperatures, it is necessary to keep warm and control the temperature above 10°C to ensure safe overwintering and promote quick recovery.
I. Change the soil
Gardenias have high requirements for soil, and yellowing leaves are likely caused by unsuitable soil, such as excessive soil stickiness or alkalinity, which can affect growth and lead to yellowing or even drying of leaves. If this is the cause, it is best to change the soil to ensure it is loose, breathable, fertile, and slightly acidic, which can promote vigorous growth of gardenias. Note that the soil should be changed every year.
II. Water properly
Gardenias prefer a humid environment and have poor drought resistance, especially during the growing season. If not watered for a long time, soil drought can easily lead to yellowing. In such cases, it is necessary to replenish water as soon as possible, preferably watering thoroughly to allow the gardenias to absorb enough water, and also ensure the soil remains slightly moist later on to promote gradual recovery. Note that they are not tolerant of waterlogging, and watering should be controlled to prevent积水.
III. Shield from light promptly
Gardenias enjoy sunlight but are not tolerant of direct exposure, especially during the summer. If not shielded from light in time during summer, prolonged exposure can easily lead to leaf sunburn and yellowing. If this is the cause, shielding from light is necessary, moving potted plants indoors quickly and setting up shade nets for outdoor cultivation to prevent sunburn and ensure timely treatment for gradual recovery.
IV. Control temperature promptly
Gardenias are southern flowers that prefer warm environments and have poor cold resistance. If not properly controlling the temperature after entering winter, prolonged exposure to cold environments can easily lead to frostbite and yellowing of the leaves, even affecting the germination in the following spring. In such cases, it is necessary to take prompt measures to control temperature and keep warm, maintaining the temperature around 10°C, allowing the gardenias to stop freezing and safely overwinter. Note that in northern regions, where winter temperatures are low, it is necessary to grow them in pots, otherwise it is difficult to control the temperature and they may freeze to death.
