Why Are Peace Lily Leaves Turning Yellow? Latest Cause Analysis
Peace lily, also called Spathiphyllum, is a perennial herbaceous plant of the Araceae family, and it is cultivated very widely in our country. The ornamental value of the peace lily is very high, and it is a delight to the eye when in bloom. When not in bloom, it is also a foliage plant, and it is welcomed by many people. However, many people often see yellowing leaves when cultivating peace lilies. So what is going on with yellow peace lily leaves? Let's take a look together with the editor below!
1. Improper Watering
During the growth process, the peace lily has a certain demand for water. But when watering, we must pay attention to controlling the amount of water well. Do not water too much or too little. If watering too much, water accumulating in the soil will inhibit root respiration, leading to root rot and affecting nutrient absorption, thus causing malnutrition and yellow leaves. But if watering is insufficient, it will also cause yellow leaves in peace lilies. Therefore, we should adjust the watering frequency according to seasonal changes. In daily care, water about once every 5 days and just keep the soil moist. In summer, water once every day, while in winter it can be kept at once a week.
2. Too Much Fertilizer
The growth of the peace lily also needs a certain amount of nutrients, so fertilizing is also indispensable. But just like watering, we must likewise pay attention to controlling the amount of fertilizer. If too much fertilizer is applied, the peace lily plant is very prone to fertilizer damage, causing root burn and leaf burn, resulting in yellow leaves. So everyone must pay close attention: if too much fertilizer causes yellow leaves, then we should water promptly to flush out the fertilizer and dilute it. Then place it in the sun to dry. The fertilizing frequency for peace lilies should generally be kept at about once every half a month. Fertilizers are mainly cake fertilizer, compound fertilizer, etc. In winter, because the peace lily enters dormancy, fertilizing can be skipped.
3. Unsuitable Light
Although the peace lily likes to grow in an environment with sufficient light, the light intensity must not be too strong. If exposed to scorching sunlight, it can easily cause leaf scorch, and the leaves will yellow because of this. However, also note that the peace lily must not stay in a shady, low-light environment for a long time, otherwise yellow leaves are also likely to appear. Therefore, we should likewise control the light according to the seasons. In winter and spring, the peace lily plant can be given sunlight all day. But after summer arrives, because the sunlight is stronger, shading work should be done well to avoid the leaves being exposed to strong sunlight.
4. Temperature Too Low
The peace lily has relatively high temperature requirements and likes to grow in a warm environment. The suitable growth temperature is around 12-28 degrees, the lowest temperature must not be below 5 degrees, and the highest should also be kept below 35 degrees. If the temperature is too low, the peace lily plant will suffer cold damage, and after the leaves are frostbitten they easily turn yellow. If the temperature is too high, it will speed up water evaporation, and the leaves will lack water, causing them to wilt and turn yellow. Therefore, in winter we should do a good job of cold protection and heat preservation, and similarly in summer we should cool it down promptly to ensure the normal growth of the peace lily.
