Gardenias are relatively difficult to cultivate, especially in the north, where they easily develop yellow leaves. There are several types of yellowing leaves in gardenias, and today, Xiaoqi will talk about several reasons for the yellowing leaves of gardenias.
The first situation is the most common, where the new leaves of the gardenias we grow turn green in the veins, but the rest of the leaf turns yellow. What is the reason for this? It is caused by the alkaline water quality and soil, which leads to the soil being alkaline. The gardenias lack iron elements, and in alkaline soil, iron cannot be absorbed. Therefore, the new leaves of gardenias turn yellow. If this situation is discovered and is severe, it is recommended to repot the plant. If only a few leaves have just started to grow, you can water the plant with ferrous sulfate, which should be diluted at a ratio of 1:1000, directly poured into the potting soil, allowing the new leaves to gradually recover. Therefore, when growing gardenias at home, it is essential to keep the soil acidic, and periodically, every 1-2 months, water with a solution of ferrous sulfate to ensure the soil remains acidic and does not lack iron, preventing the yellowing of leaves.
The second situation involves yellow veins with the rest of the leaf being green, eventually leading to the entire leaf turning yellow. This situation often occurs after repotting gardenias. The main reason is root damage, which prevents the absorption of nutrients. As nutrients are supplied from the roots to the trunk and then distributed to the leaves through the veins, the lack of nutrient supply to the veins causes them to turn yellow and gradually spread to the rest of the leaf. This could be due to severe root damage during repotting, a lack of fertilizer during care, or overwatering and poor ventilation leading to root rot. Analyzing your care situation accordingly can help solve this issue. If it occurs after repotting, you should allow the plant to recover and grow new roots, which will effectively alleviate the situation.
The third situation is when the lower leaves turn yellow in large areas, which is mainly caused by a lack of water and fertilizer. For example, if you forget to water the plant one time and the whole plant wilts, the lower leaves will turn yellow and fall off after watering. If you do not fertilize for a long time and the plant grows rapidly, the lower leaves will also show this condition. If there is a lack of watering or fertilizer, this situation can occur. Therefore, when growing gardenias, ensure adequate watering, and when the soil surface is dry, water thoroughly. Provide fertilizers regularly and in the right amount, using multi-element fertilizers during the growing season and fertilizers high in phosphorus during the flowering season, about 2-3 times a month, following the principle of applying thin and frequent fertilization, which will help the plant grow well without yellow leaves.
Generally, there are only these three situations for gardenia leaf yellowing. By analyzing your care routine, you can determine which situation applies and solve the problem accordingly.平常养栀子花尽可能多给它见光照，它是强阳性的花卉，特别的喜光，浇水的原则就是土表干了，及时的给它浇透水就行了，盆不需要用太大的，土壤保证着透气透水性，定期的给他补充一下硫酸亚铁，这样我们去养护基本上就不会出现问题，栀子花在您的家里也能够长得非常的好。
Yellowing gardenias usually have these three situations. By analyzing your care routine, you can determine which situation applies and solve the problem accordingly. Gardenias should be exposed to as much sunlight as possible since they are sun-loving plants. The watering principle is to water thoroughly when the soil surface is dry. The pot does not need to be too large, and the soil should be well-draining and ventilated. Regularly supplementing with ferrous sulfate will ensure that there are no problems in caring for the plant, and gardenias can grow very well in your home.
