How to treat dry and withered leaves on a potted Peace Lily tree? Detailed solutions

The potted Peace Lily tree has very high practical value: it can be enjoyed, beautify the environment, and eliminate harmful gases, but only with good care and management can it have these functions and show its application value. The Peace Lily tree is very suitable for foliage viewing. To give full play to the application value of the potted plant, the leaves must maintain a good growth state; once the leaves develop problems, all application value is lost. This is especially true when the leaves of a potted Peace Lily tree become dry and withered, so what then?

The Peace Lily tree likes a warm, humid growing environment and is characterized by being intolerant of drought, cold, and waterlogging, and its root system consists mostly of fibrous roots, so its absorption capacity is limited and it is also underdeveloped. Because its root system is relatively weak, it is often easily affected by water and fertilizer, especially excessive watering and overly high fertilizer concentration, which tend to damage the roots. The dry and withered leaves of the Peace Lily tree are mainly caused by improper water and fertilizer management. Of course, exposure to the scorching summer sun cannot be ruled out either.

1. Excessive light

The growing environment of the Peace Lily tree requires ample light, but it also has a certain tolerance for shade. Even though it likes light, it also fears scorching sun exposure, because under the scorching summer sun the leaves accelerate transpiration, while its root system consists mostly of fibrous roots and its absorption capacity is often limited. When evaporation exceeds the roots' water uptake, the balance of water supply and demand is often broken, resulting in dry and withered leaves. In fact, this is also a form of self-protection by the Peace Lily tree, mainly by sacrificing leaves in an effort to achieve a balance between water supply and demand. Therefore, in summer it is essential to avoid scorching sun exposure and better to place it indoors in a ventilated, sunny spot, while increasing watering and misting to retain moisture and lower the temperature.

2. Improper watering

Since the root system of the Peace Lily tree consists mostly of fibrous roots, its natural water absorption capacity is limited, so once it is overwatered, the water cannot be consumed in time, which easily causes water accumulation in the pot or overly moist potting soil. In a high-temperature, unventilated environment, this very easily causes root suffocation and root rot, and in severe cases it may directly cause rotten roots. Since the root system of the Peace Lily tree is damaged, it naturally cannot absorb and transport water smoothly, and the tree body cannot receive timely water replenishment, thus showing dry and withered branches and leaves. But if the pot remains in a water-deficient state for a long time, the plant will often also develop dehydration, leading to dry and withered branches and leaves. Therefore, watering must not only be timely but also appropriate in amount. When water is lacking, water promptly; when there is too much water, promptly find a way to drain it off.

3. Excessive fertilizing

The Peace Lily tree relatively likes fertilizer, but it also fears concentrated fertilizer and raw fertilizer. If the pot lacks nutrients, the plant sometimes shows yellowing and withered branches and leaves, but dry and withered leaves are mostly caused by excessive fertilizing. This is the same principle as overwatering: overwatering or overfertilizing often causes root rot, which in turn leads to dry and withered leaves. Therefore, in normal fertilizing, always focus on low concentration and dilution, applying thin fertilizer frequently, especially during the growing season. If too much fertilizer is applied, promptly water heavily to dilute the fertilizer, and at the same time let the excess fertilizer drain out through the drainage hole at the bottom of the pot. But if the root system is severely damaged, promptly take the Peace Lily tree out of the pot, trim the roots, sterilize them, and then repot it.
