Hello, looking for a little help. What could be the problem when the leaves of an orchid fail to open up? What I mean is, the leaf normally has a "crease" running lengthwise, but the leaf unfolds, so to speak, as it grows. I have an orchid where a leaf is staying folded. I hope the attached picture illustrates the problem. It's the newest leaf on the left. This orchid has a long and troubled history. I bought it from a grocery store many years ago, re-potted using orchid mix and a holey pot, watered once a week, kept near a north-facing window, and the orchid did great. Bloomed once a year for a few years. But then one winter the heat went out while we were out for town for the week, and the leaves wilted. Eventually it did produce two new very small leaves. I re-potted again, using a smaller pot (there were very few viable roots left), and the plant made a few more leaves - but now the latest one seems to be stuck in the "folded" position. I've looked at a lot of orchid guides and pictures of problem leaves, but haven't been able to find this particular problem. Help?
