What to Do When a Potted Peace Lily's Leaves Turn Black?
The peace lily, also known as Spathiphyllum or white sail, is a foliage and flowering plant with a unique flower shape. Its flowers are white, and its flowering period is from May to August; from a distance it looks like a statue of Guanyin. Many people grow it as a potted plant at home, both to decorate the environment and to purify the air. When caring for peace lilies, the phenomenon of leaves turning black often occurs. What should you do? Let's take a look together below.
1. What should you do when a potted peace lily's leaves turn black?
1. Light that is too intense
The peace lily is fairly shade-tolerant. If it is kept outdoors, it is very easy for direct sunlight to scorch the leaves, causing them to turn yellow and black. This phenomenon easily occurs during hot summer weather. This is especially true for plants that have been kept in a shady spot for a long time; placing them suddenly in blazing sun will cause this phenomenon.
Solution: During normal care, place it in an indoor spot with scattered light, such as on a dining table or coffee table. In spring and winter, when there is sunlight, it can be moved outdoors appropriately; in summer, it generally should not be kept in a sunny position on a balcony or windowsill.
2. Overwatering
During normal care of the peace lily, if it is watered too much, the leaves very easily turn black. This is because water accumulates in the potting soil and it is not breathable, so the roots cannot breathe, and the whole plant cannot absorb nutrients and water. In severe cases, the entire peace lily will die.
Solution: If too much water is accidentally given, measures can be taken immediately to rescue it. Take the peace lily out of the potting soil and check whether the roots have already begun to rot. If the rot is severe, prune, disinfect, and then replant it. For the first few days after changing the potting soil, place it in a cool, ventilated place. During normal watering, decide based on the moisture level of the potting soil and the plant's growth stage. Do not water too much or leave it unwatered for a long time; both will affect the plant's growth.
3. A growing environment without ventilation
If you want the peace lily to grow well, have emerald-green leaves, and bloom on schedule, it must be kept in a ventilated place for care. Otherwise, the leaves are easily infected by bacteria or fungi and turn black.
Solution: During normal care, be careful to place it in a ventilated spot with scattered light, and keep the leaves clean without letting too much dust accumulate. Once pests or diseases occur, treat them promptly with the right remedy, so as not to affect the whole plant.
2. Can the peace lily remove formaldehyde?
The peace lily can absorb exhaust gases from the air, which is also why everyone likes to grow it. Not only that, the peace lily can also remove part of formaldehyde, but wanting to rely on it to absorb all the formaldehyde brought by an entire newly renovated house and new furniture is actually not very realistic. Unless dozens or hundreds of pots are placed, it may have a certain effect.
In addition, the peace lily can also be kept in a ventilated spot in the kitchen, which can effectively absorb cooking fumes and the smell of cooking. However, be sure to pay attention to keeping the leaves clean, otherwise it is very easy for pests to develop and for the plant to die.
Through the introduction in this article, I believe everyone already has their own answer to the question of what to do when a peace lily's leaves turn yellow. Compare with it and solve the problem reasonably.
