Why Are Peace Lily Leaves Turning Yellow? Full Analysis of Causes and Solutions
The peace lily is one of the most common potted plants in the home. Its blooming period is extremely long, and its flowers are quite beautiful. Even when it is not blooming, keeping it indoors still provides an excellent visual pleasure and also helps purify the air. But many friends find during cultivation that their peace lily leaves turn yellow, which seriously affects its ornamental value. So what causes yellow leaves on peace lilies? Let's take a look together.
1. Soil degradation
Long-term watering and fertilizing can easily cause the soil layer to harden and clump, which is extremely unfavorable for root growth. In addition, water struggles to seep down to the roots, and when the roots cannot absorb water, the leaves will gradually turn yellow.
Solution: Every year, divide and repot the peace lily. The growing medium should be leaf mold or peat soil, mixed with some sand to improve the drainage performance of the medium. To remove it from the pot, first take the main plant out of the pot, remove part of the old soil, then transplant it into new potting soil. After potting, water thoroughly, then place it in a cool place for care.
2. Insufficient watering
During growth and development, the peace lily has a very high demand for water. If it is not watered promptly during drought, its leaves will turn yellow. Especially in summer, if it is not watered for a long time, it is very likely to cause the whole plant to wither and die.
Solution: Water immediately during drought. During the vigorous growth period of the peace lily, water more frequently, and the growing medium must be kept moist. However, the water volume should also be controlled so it is not too large, to prevent water accumulation from drowning the roots and harming their breathing.
3. Lack of light
Although the peace lily is shade-tolerant, if it is kept in a shady place for a long time, this is not only unfavorable for its growth and development, but also causes yellow leaves due to insufficient light, and it will be unable to bloom normally.
Solution: In winter and spring, give the peace lily sufficient light and it can be kept in sunlight all day. In summer, because of high temperatures and strong light, proper shading is needed during care to avoid strong sunlight exposure and harm to the plant.
4. Temperature too low
The peace lily has a certain resistance to high temperatures, but no resistance at all to low temperatures. In winter, when the temperature is below 14°C, it is very easily frostbitten, and the leaves will turn yellow after frostbite. If it is below 10°C, it may freeze to death directly.
Solution: When caring for the peace lily, place it in a warm area with the temperature controlled at around 22-28°C. Because it is very afraid of cold, in winter it should be put into a greenhouse, or a bag should be used to cover the upper part of the main plant for insulation, so it can overwinter safely.
