Looking to give the gift of good luck? Money trees are traditionally given to others to wish them good luck in a new endeavour or business venture. They are easy to maintain. Light: They are looking for the part sun part shade space. So no direct south-facing windows, but it will die in that dark corner. Water: Water when dry on the surface this could be as littleas every other week in the winter and as often as weekly in the summer, of course, this depends on how much light it gets. Humidity: They like normal humidity but will suffer directly in front of a vent.
