We turned off the heat in our house when we went on vacation. Whether or not it was the smart thing to do, that's what we did. When we returned a month later the Wisconsin winter had made it freezing inside. Our "palm plants" (we're not sure of the species)now look pretty dead and their leaves hang lifelessly down. Now almost one month later they haven't changed. I told my wife that they'll probably get better when it gets warmer here. For now we've moved them to a modestly warmer and sunnier room. Anybody out there have any advice to help our plants out? Perhaps a type of spray or nurishment? Any advice is greatly appreciated.
