I've had my lucky bamboo for over 2 years. It has done extremely well and has outgrown its pot. It's not planted in dirt but submerged in water. I decided to put it in a larger pot a week ago. However, it was stuck in its old pot because there are a lot of roots packed into a small space. I had to firmly and slowly nudged it out. Now, in its new and larger pot, almost all the leaves have turned yellow. Also, two of the stems have turned yellow too. The water has also begun to smell even after changing it. I think that I may have traumatized it and killed it. Is it salvageable? I've given it plant food but it is not helping. More leaves are turning yellow.
