Sounds like you had a very nice blooming period. As Janet said, some phals will just keep it up. I have one that bloomed for 11 months. Now that it's done blooming, you can cut the flowering stem back and you may want to check the roots and see if it's necessary to repot. Check out the cultural sheet below and then fire away with your questions. Oh, and welcome to the forum.
