Why Does My Peace Lily Have Black Leaves?
I have tried placing my peace lily in different spots around the house, and it still gets black on the tips of the leaves. Am I watering it too much or little?

Black leaf tips are more likely to be caused by underwatering than overwatering. (Yellowing of leaves is more likely with overwatering.) However, the black tips are more likely an indication of low humidity than underwatering. If possible, try grouping the peace lily with other houseplants to raise the humidity in the area around the plants. The blackened leaf tips could also be due to excess salts in the soil, either from too much fertilizer or fluoride/chlorine in the water.
