What to do if the leaves of gardenia turn yellow
The editor will answer how to deal with the yellowing leaves of gardenia and share the related experience of flower planting for补救 measures of yellowing leaves of gardenia. Detailed content will be shared next.
Change the soil: If the yellowing leaves are caused by the stickiness or excessive alkalinity of the soil, it should be replaced with loose, breathable, and slightly acidic soil as soon as possible.
Water properly: If the 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 light, 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 warm up and control the temperature above 10°C to ensure safe overwintering and promote rapid recovery.
I. Change the soil
Gardenia has high requirements for soil, and yellowing leaves are likely caused by unsuitable soil, such as excessive 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 to promote vigorous growth of gardenia. Note that it is necessary to change the soil every year.
II. Water properly
Gardenia prefers a humid environment and has poor drought resistance, especially during the growing season. If not watered for a long time, the soil dries out and can easily cause yellowing. In such cases, it is necessary to replenish water immediately, preferably by watering thoroughly to allow the gardenia to absorb enough water. It is also important to keep the soil slightly moist later on to promote recovery. Note that gardenia is not tolerant of waterlogging, so watering should be controlled to avoid waterlogging.
III. Shield from light promptly
Gardenia enjoys light but is not tolerant of direct sunlight, especially during the summer. If not shielded from light in time during summer, prolonged exposure to strong sunlight can easily sunburn the leaves, causing yellowing. In such cases, it is necessary to shield from light, moving potted plants indoors and using a shade net to shield from light for outdoor cultivation to avoid sunburn and promote recovery over time.
IV. Control temperature promptly
Gardenia is a flower of the south, preferring warm environments and having poor cold resistance. If unable to control the temperature well after winter, and if the plant remains in a cold environment for a long time, the leaves can easily freeze and become frostbitten, leading to yellowing and even affecting the germination in the following spring. In such cases, it is necessary to take measures to control temperature and keep warm, maintaining the temperature around 10°C, allowing the gardenia to stop freezing and safely overwinter. Note that in northern regions, the winter temperatures are low, and it is necessary to grow gardenia in pots to control the temperature, otherwise, it may freeze to death.
