Hello all... I was given a Lucky Bamboo as a gift last Christmas. It has 8 stalks and is actually Dracaena sandera. When it came to me it was in a glazed pot of soil with rocks or pebbles glued to the top. I've tried to break the rocks apart but am unsuccessful because I'm afraid I'll damage the stalks.

So I just pay attention to it as I cannot even tell what kind of soil or how moist it is under all those pebbles. Surprisingly enough the plant has grown so much new foliage on top and does look pretty happy... until yesterday! I noticed that one stalk is turning yellow :( I do love this plant and would love to keep it happy and alive..

Any suggestions and advice would be very welcome, and I don't want to lose a stalk because I want to have all 8 together.

Oh, btw, I water it about once every week-week and a half and it sits about 5 feet from an East window.. Don't really fertilize this one.
