I have a Pachira plant and it is loosing it's leaves and one of the stems have no leaves and lookes dried out... How can I save it and remove the dead stem that is inter-twined with the other stems without hurting the plant. I water it every 14 days but the dirt seems so dried out bt then... am I doing it right? how can I fix the problem and save my plant? How do I know if it needs to be repotted. Thanks, Lourdes
