About two months ago I acquired a large bird of paradise plant. I keep it indoors, about 15 feet away from a north facing window.
Its leaves have been browning and curling, which I believe is either a sign of under or overwatering. I worried the soil might not be well-draining enough so I watered it relatively infrequently, about once a week.
I live in a small apartment, so it's difficult for me to de-pot the plant to see if it has root rot. How can I figure out what the problem is and save my plant?
