Abstract
A fill tube for a water filled plant protector is formed by folding the top edge of the outer wall of the protector between the inner and outer walls and capturing the edge with the welds that create the vertical columns. The protector is filled through a port in the tube. Air is vented as the columns fill with water through the open top of each column.
