Got this Boston Fern from an old couple on marketplace. They have been growing this for 10 years. Its huge. It was much larger and fuller. I added a humidifier and consistently water. But it has excessive shedding and leaves are brittle. The pot is huge. I do not want to repot it. Could I fix this and not let it die? I feel horrible. I will be moving it to my balcony come late April when temperatures are better.
