Hello, the stem has gone brown. But there's been a new leaf! And she's continued to grow as the stem got more brown and dry. Is this just what happens when it's wintertime? Does it need more water? I water it around once a week. Is she dying? Can I do anything? I've attached photos. She's flowered this year and the brown stem started happening about a week after the flowers fell. If that gives you any more information. She's usually in filtered light. But I do give her full sun occasionally.
