Not moss but algae. I would 'guess' that the algae is using up all of the oxygen in the water. The bubbles are the carbon dioxide it produces during respiration.

Plants need oxygen at the roots just as much as they need water. Plant forced to grow in water must be able to access oxygen from the water. Algae can be a real oxygen glutton.

I would thoroughly clean and bleach the vase. Gently clean the dracaena ('bamboo')and give the roots a trim before placing it back into fresh water.

Keep all of the algae out of the water from now on. Using something besides glass would help, and the roots might even be happier in the dark.

They are very sensitive to water with chemicals in it. Do you use bottled water or tap water? If you are using city water, that they may have changed the chemicals they are using. I agree you have a algae problem but it might be that the plant's bad health is causing the algae to grow.

p.s. They get big and happy if you grow them in soil!

Thanks for the reply.

I took my bamboo plant outside to clean the vase. I left it outside for some time- thinking the fresh air and sun would do it good. However, the following day - after the plant had been brought in- the leaves started to turn yellow. There is no algae in vase - clean water. Plant is about 5 years old. Did I burn my plant when it was outside?? Can I revive this beauty?? Should I cut back all the yellow leaves?

I have two bamboo plants in the same clear glass vase. They have been together ever since I bought them. About a week ago one of them's leaves has started to turn yellow and is starting to wilt. And the other i startign to show signs of it at the tips. I have tried cleaning the vase and even gently washing their roots alittle bit but it seems to be getting worse. I live in Texas and it could be that it is too hot outside but what do i do? Any advice will be appreciated. Thanks so much!

My wife went on vacation for a month and I really messed her bamboo up-I think I under watered it. What is the best way to revive a bamboo with many dead branches? For some dumb reason I thought I was over watering it. By the way, it's about 5 feet tall. Is there a way to make it bushier/grow new branches??

Thanks for your help.

Sincerely,
Fred

Hi, so one of my three stalks has turned yellow, but only on one side...the other side of it is green. Also, the leaves on this stalk are VERY green. Is it hopeless, or is there something I can do to fix this?

Thanks in advance,
Jess
