Q.My lucky bamboo plant stinks!
We have had a lucky bamboo for several years. Recently, it has begun to stink and mildew. What can I do to help it not smell? We had it in the kitchen window and put up shades a couple of weeks ago. Will it live outdoors, in Phoenix (110• summers)? It smells too bad to keep inside right now, but we do not want to get rid of it. I changed the water out twice in the last week, but it still stinks! Please help us keep our plant alive.

Your bamboo may have developed root rot.
Keeping the water clean is very important.
You can try dipping the roots in a fungicide.
