Stalk rot

A yellowing stalk is the serious one — it usually means the stem is rotting from within.

Diagnosis

Stalk rot

What's happening

When a lucky bamboo stalk turns yellow and soft, the tissue is dying, most often from sitting in stale water, being kept too deep, or rot spreading up from the base. Unlike a yellow leaf, a yellow stalk does not recover, and the rot can travel up the cane and spread to healthy stalks sharing the same water.

How to fix it

Remove the yellowing stalk right away so it doesn't infect the rest. If only the top is yellow, cut back to firm green tissue with sterilized snips and seal the cut with a little candle wax to keep rot out. If the whole cane is yellow and mushy, discard it. Rinse the vessel and stones, refill with fresh clean water, and keep the level at about an inch or two — deep water encourages this kind of rot.

What fixes it

  • Clean pruning snips — Clean, sharp snips give a precise cut back to healthy tissue without crushing the soft stem.

If that doesn't fix it

This is general guidance based on common symptoms; individual plants vary.
