The palm we recieved was green and beautiful and we have been watering the palms regularly, once a week and then went to twice a week and the leaves are turning brown. I have read everything there is about the christmas palm, the palm sits in the front office reception area and we think someone poured soda into it and now its turning brown, how do we remove the soda from the root system, or is this possible? Thanks, my order #100096301.
