I've had a lucky bamboo for a number of years and it has grown a lot. Now the leaves are turning yellow and dying. I have separated the three stalks and put them in two separate vases and they are growing new roots but I'm still losing leaves. Do they eventually grow too much and die, or is there something I can do to save them?
Make sure you are changing the water every 2 to 4 weeks.
Tap water that contains salts can cause leaf yellowing. Use distilled water for your Bamboo.
Make sure they are not in to bright of a light, indirect light is best.
