My mum has had this dragon tree for 20 years. I live in the uk and the most recent winter was colder than usual so I'm not sure whether that had an impact. unfortunately, I have always neglected it, And didn't water Frequently – sometimes left it six weeks or more, a few years ago. In September 2023, I replaced the compost that hadn't been replaced for quite a long time with coco coir, but still watered in frequently. I only started watering every two or three weeks, a few months ago (with tap water, like i always have done). However, for the past few months at least, it has been looking like it was in the pictures and possibly dying. I don't know how to save it. It seems to get enough light though. Any help would be appreciated. There's only one green crown,which is the top stem that has a crown with green leaves inside it whereas the rest either fell off after turning brown and wilting.
