My friend gave me a very much dying Lucky Bamboo to plant sit, picture attached, can I salvage it? Watered once a week, lives in a windowsill, has been in the same pot/soil since September. Also, I killed mine instantly, so please explain as if I am an idiot. Windowsill previously North facing, will be temporarily in South facing, will likely be moving to South-Southwest facing window. Location is Wisconsin, if that impacts sun exposure.
