I have a lucky bamboo planted in rocks and water instead of soil. I do not think I am taking proper care of it. Its leaves are brown on the tips and have definitely been yellowing more than they should. Also the water is filled with green algae and bacteria. We have another in the house that doesn't seem to be having any of these problems. Last summer I accidentally left it in direct sunlight for far to long and it got a sun burn. I found somewhere on the internet to cut all the dead leaves off so I did. It sits at a north facing window. If anyone has any advice, thank you!
