Reasons for Yellowing Leaves on Peace Lilies and How to Fix Them

The peace lily is one of the most common potted plants in the home, because its flowering period is extremely long and its flowers are quite beautiful. Even when it is not blooming, growing it indoors can provide an excellent visual delight and also help purify the air. But many friends find that their peace lily's leaves turn yellow during cultivation, seriously affecting 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 harmful to root growth. It also makes it difficult for water to seep down to the root system, and when the roots cannot absorb water, the leaves will gradually turn yellow.

Solution: Every year you need to 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 stem out of the pot, remove some 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

The peace lily has a great demand for water during its growth and development. If you do not water in time during drought, its leaves will turn yellow. Especially in summer, if you do not water for a long time, it is very likely to cause the whole plant to wither and die.

Solution: When drought occurs, you should water immediately. During the vigorous growth period of the peace lily, water more frequently, and you must ensure the growing medium stays moist, but also control the water flow so it is not too great, to prevent waterlogging from drowning the roots and harming their respiration.

3. Lack of Light

Although the peace lily is shade-tolerant, if it is kept in a cool place for a long time, this is not only unfavorable to its growth and development, but also causes yellow leaves due to insufficient light, preventing it from flowering normally.

Solution: In winter and spring, the peace lily should be given sufficient light, and can be kept in sunlight all day. In summer, because of high temperatures and strong light, appropriate shading is needed during care to avoid strong sunlight exposure that could harm 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 degrees, it is very easily frostbitten, and the leaves will turn yellow after frostbite. If it is below 10 degrees, 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 degrees. Because it is very afraid of cold, in winter it should be placed in a greenhouse, or a bag should be used to cover the upper part of the main stem for insulation, so that it can overwinter safely.
