Quote from this link: http://www.bamboo4luck.com/care.php Q: What do I do when the leaves or stems turn yellow? A: If the leaves turn yellow, pluck the yellow ones off or it will affect the rest of the plant. Then take out the bamboo arrangement out of the container and rinse the rocks, the container, and the roots of the bamboo and put everything back together, then add fresh water with a few drops of Green Green plant food. If the stems turn yellow, it is too late for that stalk. Please remove it and buy another stalk to replace it. On a more personal note, I found it a lot of trouble to keep the plants in water. It is easier to keep the plant in soil and just water regularly. My plant grew a lot and appears a lot healther than the ones in water only. There is a recipe in one of the links for the potting soil mix. I recall that I used moisture control potting soil and mixed it with orchid bark.

Congratulations on your new lucky bamboo plant. It looks like the yellow stalk has a green shoot on it. Is the stalk getting soft or rotting where it is yellow? It usually means that the stalk is dying when it turns yellow. If it starts to get soft or rot, you will need to cut it off. You may be able to leave the part of that stalk that is green and healthy and see if it is strong enough to form a shoot for you. Otherwise, throw that stalk out. You can attempt to root the healthy green shoot by dipping it in a rooting solution. You can also just put it in water to see if it forms roots. (This is if you have to cut off the yellow portion of the stalk.) The jelly stuff is a polymere gel that is reconstitued with water. The bamboos grow nicely in this base that holds water for the plant. You will have to add water to this gel as the water evaporates and as the plant takes moisture in from the gel. If the gel becomes discolored from algae growth or minerals from the water, you can remove it and plant your lucky bamboo in soil or just use water and pebbles. The leaves and shoots of the plants grow and continue to get taller. The stalks will stay the same where they are cut. Lucky bamboo like water. Be careful about using water that has chemicals in it. You may need to let the water sit overnight to allow the chemicals to escape. Do keep your plant watered to the level of the pebbles since you want to keep the gel moist.

I initially did a tester bowl with a betta and a few stalks of lucky bamboo a few months ago. The bamboo was in about 2 inches of gravel, with about 8 inches of water on top of the gravel leaving between 4 and 6 inches of exposes stalk above the water line (I had 3 stalks in there at the time). The betta seemed to really enjoy swimming around the bamboo. He went from hanging out around a favorite resting rock to swimming laps around the bowl and sitting on one of the leaves that dipped below the waters surface. A month or so later, he (the betta) asked me to upgrade his place. Yes, my fish can talk. So I bought a 10-gallon tank and transplanted everything. The water level was raised a bit higher leaving less bamboo exposed to the air so I was concerned. But after a few weeks, the bamboo still seemed to be doing well. Fast forward a couple more months: the betta and plants are doing extremely well and I still find the betta resting on some of the lower leaves. I have even slowly added a few tank mates and more live plants to the mix. I highly recomend doing this if you have a small aquarium and a fish that doesn't jump out of his/her home since you might not be able to put a top on the aquarium. The fish are happy, the bamboo is growing extremely well, and it makes a great conversation piece whenever anyone comes over. :)

This original post is old I know, but it has received some recent activity, I am sure Kevin who started this thread is long gone, and hopefully with a healthy plant, but I would look here if I had a sick LB, with the new activity. If I ran this website, I would have a disclaimer legally written up attached, there is so much incorrect information. Thankfully, most of it was written some time ago, and I will not be hauled out and publicly tarred and feathered. Sometimes you gotta speak up! First of all, Sans (above) is very knowledgeable, and gives good clear suggestions as to where to start when figuring out why a plant is sick. Listen to only her, in this post please. not that she is the only one with good tips, but you are just receiving so many well intentioned but totally lethal suggestions. I am sort of surprised. I am going to hurt some feelings and be attacked by others, both of which I hate. I just have to speak up, because this plant is not very unhealthy, and you have kept it in quite nice shape for a long time. Most LB's are tossed within a the first year, I would bet. Please.......Do not increase light to improve the yellowing of leaves. you will have yellow burnt leaves. The number one reason for yellowing leaves on most plant types is over watering. If you feel strongly you are not overwatering, trust that and look for the second reason most likely reason, TOO MUCH light. Can it be the summer sun has made the plant feel like it moved from Anchorage to the Sahara I would need more water if I was suddenly thrown into a desert, are you changing culture from winter needs to summer needsl .Does the room get Southern exposure Get it further from the window if it does. You say you have had this plant a couple of years Honestly, that is a long time for most to keep this plant looking so nice. Your Draceana is by far healthier than the 30 or more that I see every day at work, I have the only Lucky bamboo in the building that is happy. You have done well for two years. Of all the advice you can get, no one is better equipped to diagnose what adjustments will help your plant than you. Please listen to your own instincts, reread you original post. You had two guesses, and they are the best guesses to start with. I could tell you to change water on a schedule, , how to fert, but I don't know if you are already doing that or not. If I were to give specific advice, I would ask you google yellow dry leaves on Lucky bamboo, Lucky bamboo care, Native habitat for LB and so on. You don't have to become a plant nerd, but a little bit of this really helps. Pick some sights that are really reputable, no advice from sights with adds all over them, and no forums, if you are not sure you can spot good tips over bad ones. Just good research. Flower shops are not where I would start, and yet the best article I found for you is from a flower shop. After that, come back here. It is fun to learn what others did, There are so many posters here that are golden in being helpful and accurate with their suggestions. And some, not so much. Here is part of a page with very good advice below, with link The solution for too much sun is changing out the water and not fertilizing for a couple of months. Move the plant into a bright area without direct sunlight. Too much sun can cause yellowish leaves and splitting, which can be fixed with trimming them off at an angle. and the link: http://www.flowershopnetwork.com/blog/?s=lucky+bamboo You may have to copy and paste, Link would not insert. I looked at a lot of pages for you, just poke around. My best advice to you is trust your own instincts a bit more, I think you have a greener thumb than you realize.
