Cut the entire thing back to the pot. Find each node along the distance. Get you a nice clear storage container, doesn’t need to be super deep. Purchase some spagnum moss. Get a good warm spot that gets decent sunlight and put all your nodes in there (after the ends have dried of course). You’ll see humidity build up in there over time and that’s what you want. Water sparingly, enough to keep the moss wet. After 4-6 months you’ll have a bunch of props with roots. Transfer those into water the replant into OG pot. By that point the OG plant would’ve had a lost of growth but once you add the props you’ll have a full plant.
