Time to trim and propagate
A well-lit stalk that's simply gotten tall and bare just needs cutting back to bush out.

Time to trim and propagate
What's happening
Lucky bamboo keeps extending from the top of each cane rather than branching on its own, so even a healthy plant grows leggy over time with a tuft of leaves stranded at the top. Topping the stalk redirects its energy into new side shoots lower down, which is how you get a fuller, shorter plant.
How to fix it
Cut the main stalk to the height you want, just above a node (one of the raised rings on the cane), using sterilized snips. New shoots will sprout from the node below the cut, making the plant bushier. Don't throw away the top you removed: seal the parent's cut with a dab of candle wax to block rot, then set the cutting in a couple of inches of clean water and it will root in a few weeks to grow as a new plant.
What fixes it
- Clean pruning snips — Clean, sharp snips cut just above a node so the cane branches instead of crushing and rotting.
If that doesn't fix it
This is general guidance based on common symptoms; individual plants vary.
