To provide a method for arranging raising seedling vessels left and right continuously mechanically, easily and stably in improved operating efficiency.

This method for arranging raising seedling vessels comprises the following practice: raising seedling vessels A are successively fed on the whole surface of a conveying means 5 capable of moving such vessels from higher one side to the lower other side by the aid of their own weight with no driving force and stopped at a blockage 15, and on pushing the vessel A in the rearmost position with a specified force, the vessel A lying in the forefront of the row goes across the blockage 15 and descends, and by making use of the reaction force in placing the thus descended vessels A on a table, the machine body is moved.
