Q.Peace Lilly Has yellowing/brown leaves
I transplanted it 2 months after I got it. I may have put it in a pot that is too large. But I’ve always tried to water regularly, not letting it droop, and just checking soil. The light is indirect. Can you help? I’m sorry there is no picture. I tried to send, but I cannot.
You may have determined the cause yourself for the yellowing leaves on your Peace Lily.
Peace Lily prefer to be tighter in a pot. To large of a container can lead to root rot.
I would reduce the size of the container on your plant. Trim away the dead plant material and give the plant time to adjust.
Do not over water. Only water when the top inch or so dry out.
