If caught early and you notice just a small amount of yellow, change the water (distilled water) and move to a place with a little less light. If it is worse than that, but there is still green up top, just cut off the bottom and place it in a new container with fresh water.

To save a dying indoor bamboo plant, you should do the following:

• Avoid using chlorinated tap water
• Watch your indoor temperatures
• Clean the bowl and change out the water often
• Track soil levels and make sure you’re not overwatering or underwatering
• Fertilize only once or twice a year
• Prune dying or dead leaves and stems
• Don’t give the plant too much or too little light
• Look for insects and get rid of them
