What part of your lucky bamboo is yellow, is it just the leaves or are the stocks also green? If the stocks are also yellow your
plant might be shot. If it's the leaves you may still be in business! Lucky bamboo is very sensitive to the chlorine in our water, it seems to preform better if you use bottled water and change the water less often. I hardly ever change the water in mine and only top it up with bottles of water that I haven't finished. Has the
plant undergone any changes lately? Have you moved it's location! Lucky bamboo dosn't like to be in sun and does well in low light.
Any more info that you can give me to help figure out your
plant would be appreciated!
