What to do if the leaves of the gardenia turn yellow
Summary: This article discusses how to deal with the yellowing of gardenia leaves and provides knowledge about remedies for yellowing leaves in green plants and flowers. Let's explore this topic together.
Caring for gardenias often results in yellow leaves, but using this "water" can make the leaves lush and green
Gardenias are one of the flowers we often cultivate. When they bloom, they are pure and elegant, with a strong fragrance that is deeply loved by people. During the cultivation process, yellowing leaves often occur. There are usually many reasons for the yellowing of gardenia leaves, such as lack of fertilizer, lack of water, iron deficiency, or excessive fertilization. It is important to carefully observe the real cause of the yellowing leaves and take different measures in a timely manner for prevention and treatment.
The symptoms of iron deficiency usually cause interveinal yellowing of young leaves, eventually leading to the entire plant's leaves turning yellow, and in severe cases, plant death. For iron deficiency yellowing, you can spray a 0.2% to 0.5% ferrous sulfate solution every two weeks or water the roots for prevention and treatment.
Besides iron deficiency, magnesium deficiency can also cause yellowing of gardenia leaves. Magnesium deficiency starts from old leaves and gradually spreads to new leaves, with the veins remaining green. In severe cases, leaf drop can lead to plant death. For this type of magnesium deficiency yellowing, you can spray a 0.7% to 0.8% boron magnesium fertilizer for prevention and treatment.
It is also important to consider whether the yellowing is caused by a bacterial infection. When the roots of gardenias are attacked by bacteria in the soil, it can spread to the leaves, leading to yellowing. In such cases, fungicides such as carbendazim, thiophanate-methyl, or mancozeb can be used to water the plants for prevention and treatment.
What to do if the leaves of the gardenia turn yellow
Gardenias require ample sunlight during the cultivation process. Long-term care in a dark place is not conducive to healthy growth, so it is important to ensure sufficient sunlight, but also to provide shading during the hot summer months to prevent leaf burn. In winter, they should be moved indoors and ventilation should be enhanced to prevent frost damage.
Gardenias prefer a warm and humid environment. Therefore, during the growing period, there is a high demand for water and humidity. It is necessary to ensure adequate water supply and to increase the amount of watering appropriately. It is also important to spray water on the leaves of gardenias to effectively increase the humidity and promote healthy growth.
During the growing period, gardenias consume a large amount of nutrients, increasing their demand for fertilizer. Therefore, during the peak growing season, it is best to apply decomposed soybean cake or hemp seed meal as organic fertilizer every two weeks to promote growth and flowering.
