Help! I purchased my birds nest fern in the spring from a local nursery and it has been very happy until recently. We have very dry heat in our bedroom where this plant lives so I’m wondering if that’s the problem? I have put a humidifier beside it that runs on low for about 12 hours a day. It is still losing leaves but it’s also trying to make new ones. It has never been repotted but I’m not sure if putting it in a bigger pot while in distress will help? It lives in a west facing room, 4 inch pot, and is always watered from the bottom.
