Why do the leaves of Chlorophytum grow yellow? What should I do if I get yellow? Let's deal with this problem!
First of all, let's analyze the living habits of Chlorophytum:
1. Chlorophytum like warm, humid and semi overcast environment. It has strong adaptability and is more drought resistant, but not very cold resistant. The suitable temperature for growth is 15-25 ℃, and the overwintering temperature is 5 ℃. When the temperature is 20-24 ℃, the growth is the fastest, and the growth stops above 30 ℃. Chlorophytum has requirements for temperature, we should pay more attention to the cultivation process.
2. Chlorophytum does not select soil, and grows well in sandy soil with good drainage and loose and fertile soil. The requirement of Chlorophytum on soil is not high.
3. The requirements of Chlorophytum on light are not strict. It is generally suitable to grow in medium light conditions and also resistant to weak light. Of course, it can't be exposed to the sun often. The reason and treatment of Chlorophytum leaf yellowing: 1. Improper fertilization: excessive fertilization causes the leaf yellowing, fertilization exceeds the demand of the plant, at the beginning, the leaf is bright and uneven, then the root system is rotted, and the leaf is yellow.
Treatment method: stop applying fertilizer, pour more water, or turn the basin to clean the root and replace with new soil.
2. Nutrient loss: various nutrient elements in the basin soil have been exhausted, the three elements of nitrogen, phosphorus and potassium have not been supplemented in time, the plant lacks nutrients, and the leaves appear yellow and thin.
Treatment method: the fertile loam and alum water should be replaced in time.
3. Lack of sunlight: Although Chlorophytum is a semi negative flower, at least four hours of astigmatism should be seen every day, otherwise, the chlorophyll will decrease and the leaves will turn yellow.
How to deal with it: spare time every day to bathe the Chlorophytum in the sun for a few hours, but not too much exposure to the sun.
4. Poor permeability and water permeability of basin soil: the basin soil is stagnant for a long time, and the root system is hard to breathe, resulting in yellow leaves.
Treatment method: loosen soil and control water content in time. Fifth, water it for a long time. The root of Chlorophytum lost water and the lower old leaves turned yellow. The basin soil should be watered to keep warm and moist.
Illumination
The Chlorophytum prefers a semi overcast environment. In spring and autumn, it should avoid the direct sunlight. In summer, the sunlight is particularly strong. It can only see some oblique sunlight sooner or later. During the day, it needs to cover 50% - 70% of the sunlight. Otherwise, it will dry the leaf tips, especially the varieties of flowers and leaves. It is more afraid of strong sunlight. Chlorophytum Phnom Penh will grow more beautiful where the light is weak. The yellow one is more obvious and the leaves are more bright. But in winter, we should make it more sunny to keep the leaves tender and fresh green. The family pot raised Chlorophytum should be placed in front of the south window, otherwise the leaves will lose luster or even wither. When conditions permit, it is better to rotate the flowerpot about 15 ° to the fixed direction every week to ensure the same drooping degree of the Chlorophytum.
watering
Chlorophytum like humid environment, basin soil is easy to keep moist. In summer, water should be sufficient. Spray water on the branches and leaves around noon and in the evening, and clean the dust on the leaves in time to prevent the leaves from drying up. However, the fleshy root of Chlorophytum can store a lot of water, so it has a strong drought resistance ability and will not die without watering for several days. In winter, when the temperature is below 5 ℃, water less, and do not over wet the basin soil, or the leaves will turn yellow easily.
Apply fertilizer
Chlorophytum is a kind of foliage plant which is more resistant to fertilizer. If the fertilizer and water are insufficient, it is easy to scorch and age, and the leaves turn yellow, so it loses its ornamental value. From the end of spring to the beginning of autumn, organic fertilizer can be applied every 7-10 days. However, for the varieties of flowers and leaves such as Phnom Penh and Jinxin, less nitrogen should be applied to prevent the color of flowers and leaves from fading or even disappearing, affecting the beauty. The organic fertilizer retting from bone meal and eggshell can be applied properly. After full fermentation, take appropriate diluent and water it every 10-15 days to make the flowers and leaves bright.
Liquid fertilizer is applied every two weeks during the growing season. Less nitrogen should be applied to flower and leaf varieties, otherwise the white or yellow stripes on the leaves will become less obvious when the ambient temperature is lower than 4 ℃.
trim
Cut off the yellow leaves at any time. In March of each year, the basin can be turned over once to cut off old roots, rotten roots and redundant fibrous roots. In the first and middle of May, cutting off some old leaves of Chlorophytum will promote germination of more new leaves and small Chlorophytum The root system of Chlorophytum is quite developed. After cultivation for a period of time, the flowerpot should be replaced in time to avoid root accumulation, causing Chlorophytum yellow leaves, wilting and other phenomena Chlorophytum not only can be used for viewing, but also can absorb harmful gases such as carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxide, etc. in the room, playing the role of air filter, hoping that everyone can grow a healthy and good plant.
