Can I cut it in half to make two trees?
It may be pruned to a more manageable and attractive size by making a clean cut just above the leaf bract. Smaller stalks will branch out just below the cut, resulting in a fuller, bushier plant. And yes, you can take the piece you have cut and root it in water to make another plant.
I have a 'Lucky Bamboo' plant that was so green and healthy until about 10 days ago when it started turning yellow all over quite rapidly. Today I smashed off the planter that it was given to me in and it smelled horrible. The roots are pinkish and I do not know what to do with it or if it can be saved. Any suggestions?
It is suffering from root rot. This article will help you:
im growing lucky bamboo in a large mason jar with water. I've had it for about 3-4 yrs. and it has started turning yellowish at the top of the stalks there is new growth under the water level close to the bottom of one stalk but i'm not sure what to do with the yellowing at the top of the stalks can you help
What kind of water are you using for the plant and/or how often do you fertilize? This yellowing can be an indication of too much salt, which comes from either watering with tap water or from fertilizing.
Switch to distilled water for a little while and hold off on fertilizing until the leaves stop turning yellow.
My cat likes to nibble on the leaves. Is it safe?
Although many resources hint that Lucky Bamboo is not poisonous, this plant (also known as Dragon plant--Dracaena sanderiana) belongs to the same family as lilies, which are widely known to be toxic in cats. My advice, keep it well away from your cat. It's not worth the chance. If your cat exhibits unusual behavior or excessive vomiting, call your vet immediately.
Planted in pot or pebbles. I put inside pot w/o holes and filled with water. It grew well, but now leaves turning yellow, and I need to clean pebbles and transplant in larger container.

Lucky Bamboo is actually a member of the dracaena family ( corn plants, marginata, etc). It's very adaptable, but not meant to grow in water permanently. Take it out of the water and stones, gently, and put it into a pot no more than 2" in diam bigger than the root ball. Plant in fast-draining soil (cactus soil) as you would any other plant (drainage holes in the pot, etc.etc). Keep it slightly moist in the beginning, because it has water roots, and gradually reduce the soil moisture until you are letting the soil get almost dry between waterings; this could take up to 6 months. Keep it in moderate light, fertilize no more than twice a year.
I have had this Lucky Bamboo, about 5 stalks in size, for 2 years. I left someone caring for it while I was away for about 2 weeks. Coming home I noticed she filled the container to the top with water, which I never do. Now one stalk is yellow. Do I need to remove it?
Yes, remove all that excess water, as this will lead to rotting of your plant. You may even need to let it dry out some.
I have an extremely healthy Lucky Bamboo that has grown very large. It is a bonsai styled plant that I would like to leave the pattern of the base Bamboo. What I need to know is how can I trim its height and make the trimmings root for new plants without killing or damaging the existing plants.
You can just cut those stems off at any point you like to make your plant have a pleasing shape. You can then place those stems into some type of container with water, just like the original plant came in, with some stones for support; or you can plant them in moist rooting mix: https://www.gardeningknowhow.com/garden-how-to/projects/rooting-plant-cuttings.htm
If you want to keep your lucky bamboo for the long haul, however, you should consider putting it into soil. These are not water plants by nature; they're marketed that way because they are so strong and adaptable they will grow in water for a long time, but not forever.
