A friend of mine was sold some dracaena sanderiana, also known as "lucky bamboo" by our LFS a few months ago. As most of you probably know, this plant is often sold as an aquatic plant, but in fact isn't, and hers is starting to rot. I know the obvious answer is to remove it from the tank, but she seems to like it and I was wondering if this was a feasible idea for keeping it.
The research I've done seems to say that its okay for the roots to be under water, as long as part of the plant is in contact with the air. Does this mean that its able to survive planted in a 55 gallon fish tank as long as the stalks have grown tall enough to be out of the water? That would still mean that most of the plant is underwater, but will just a few inches at the top be enough in contact with the air to keep the underwater bits from rotting? I've read that it grows pretty fast, so does it make sense to plant it in a regular pot for a while and let it get like two feet tall, then put it back into the tank?
