Q.What’s Up With My Lucky Bamboo??
Had my lucky bamboo for a year now and in that time it’s grown considerably and has been very healthy. I’ve had no problems with it till now but recently I noticed leaves yellowing and it was so much a whole shoot yellowed so I cut it off and now the stalk of one of them is yellowing. It’s not a pest infestation I keep it next to my other plants and they are all growing just fine and I’ve inspected it. There aren’t spots on the leaves they just lighten in colour till they turn yellow. I don’t think it’s root rot, it doesn’t smell bad it smells like freshwater and the roots aren’t black. I’ve taken it out of its pot and cleaned it and put it back and still yellowing. I left it for 2 days and I thought it might be nutrient deficiency so I filled it with water I left it outside for a few days after I added 2 drops of liquid fertilizer to the water and the yellowing still continued. I think it might be a temperature problem because my window has some problems and I’ve had to use a heater because it’s cold but my sister’s bamboo is healthy when her room is colder than mine and she’s been using a bigger heater in hers for longer.

That Dracaena only has a couple of roots! That is all it has to take up nutrients, so until the roots fill out, this is what you will expect from the plant.
Unfortunately, without proper nutrients and care, constantly, this will be a very slow process.
If you would like to speed things up, you can plant it into soil to grow as it is intended to do. In water, such as this, it is not really designed to grow, or to live very long at that.
Here are some articles that will help you to care for the plant:
