What to do if the water-grown Spathiphyllum turns black

1. Change water in time

If the water of Spathiphyllum grown in water is not changed for a long time, the water quality will be polluted, causing bacteria to grow inside, which may cause it to turn black. You can cut off the blackened roots and leaves, then clean the container, dry the tap water and put it back into the container, and then continue to put it in for maintenance. After that, pay attention to the frequency of water changes. When the temperature is high, you can change the water every 5-10 days. When the weather turns cooler, you can change the water every 15-20 days to ensure a clean water environment.

2. Adjust the temperature

It cannot withstand cold climates, especially the Spathiphyllum grown in water. When the temperature in winter is below 5 degrees Celsius, the plant will find it difficult to grow normally and will suffer from frost damage, causing the Spathiphyllum grown in water to turn black. The temperature needs to be adjusted in time, and the plants should be moved indoors for maintenance in winter. It is best to maintain the temperature above 10 degrees Celsius.

3. Lower the water level

When growing Spathiphyllum in water, if too much water is added, causing the water level to rise, too much water will enter the rhizome, which may cause it to rot and turn black. Take the plant out, trim the blackened parts appropriately, and then add water and maintain it again.
