What is the reason for the yellow leaves of gardenia?
About the reason for the yellow leaves of gardenia and the explanation of the green plants and flowers in terms of the causes and solutions, the following is a detailed introduction for you.
Gardenia is relatively difficult to cultivate, especially in the north, where it is prone to yellow leaves. There are several types of yellow leaves in gardenia, and today, Xiao Qi will tell you about several reasons for the yellow leaves of gardenia.
The first situation is the most common, where the new leaves of the gardenia we raise turn green in the veins, and the rest of the parts turn yellow. What is the reason for this? This is caused by the alkalinity of the water quality and soil, leading to the soil becoming alkaline. The gardenia lacks iron elements, and in alkaline soil, iron cannot be absorbed. Therefore, the new leaves of gardenia turn yellow. If you find this situation and it is severe, it is recommended to change the pot for it. If only a few leaves have just started to grow, you can water with ferrous sulfate. The concentration of ferrous sulfate should be 1:1000, directly watered into the potting soil, which will ensure that the new leaves gradually recover. Therefore, when raising gardenia at home, it is necessary to keep the soil acidic, and water with ferrous sulfate solution every 1-2 months to ensure the soil remains acidic and does not lack iron, so that gardenia will not have this type of yellow leaves.
The second situation is that the veins are yellow, and the rest of the parts are green, and gradually, the entire leaf turns yellow. This situation actually occurs most easily when we just repot the gardenia. The main reason for this situation is root damage, which causes the roots not to absorb nutrients. Nutrients are supplied from the roots to the trunk and then分散 to the leaves through the veins. Therefore, without nutrient supply, the veins have no nutrients, and they gradually turn yellow and spread to the surrounding leaves, leading to this situation. Either you have just repotted it and the root damage is severe, or you have been lacking in fertilization during the maintenance process, or you have watered too much and poor ventilation has caused root rot. Analyze according to your maintenance situation, and you can solve it well. If this situation occurs after repotting, you need to slow down the seedling growth and let it grow new roots, and this situation will be effectively alleviated later.
The third situation is that the lower leaves turn yellow in a large area. The main reason for the large area of yellowing of the lower leaves is the lack of water and fertilizer. For example, if we forget to water once, the entire plant will wilt, and after watering, the lower leaves will turn yellow and fall off in a large area. If we do not apply fertilizer for a long time, and the growth is relatively fast, the lower leaves will also have this situation. If you do not water for a long time, there will be a lack of water or fertilizer, and this situation will occur. Therefore, it is necessary to ensure sufficient watering when raising gardenia, generally water when the soil surface is dry, and supply fertilizers regularly and quantitatively. Use 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 fertilizer frequently, which will make it grow well and not have yellow leaves.
Usually, there are only these three situations of yellow leaves in gardenia. By analyzing your maintenance, you can figure out which situation it belongs to and solve it well. Usually, try to give gardenia more sunlight, as it is a sun-loving flower. 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 kept breathable. Regularly supplement with ferrous sulfate, and basically, there will be no problems in maintenance. Gardenia can grow very well in your home.
