The technical solution refers to forestry, and more specifically to manual devices for planting seedlings of forest cultures with a closed root system grown in containers. The device for planting seedlings with a closed root system includes a vertical guide tube with a funnel and handle at the top, a working member for forming a pit seat in the lower part comprising two blades, one of which has a hinge pin and is fixedly attached to the lower end pipes, and the other is movably pivotable about the hinge axis, a spring for returning the movable blade to the closed position, a pedal for rotating the movable blade, and a mechanism for fixing the movable blade in the open floor an insert containing a rod, a spring, and a fixing element. At the same time, the working element for forming the seat is provided with a closed oval frame with openings on the sides for hinging connection with the axis of the hinge of the fixed blade and an additional pedal for insertion of the working element into the soil, the pedal of insertion into the soil and the pedal of the swivel blade are welded to an oval closed frame from the outside on opposite sides of the hinge hole in the plane passing through the axis of the vertical pipe, and the swivel blade to the enclosing y a part of a closed frame. And the fixing element of the mechanism of fixing the movable blade in the open position is made in the form of an arcuate plate with a radial hole located above the hinge and welded to the upper edge of the frame side frame, and the movable blade fixing mechanism is provided with brackets with guide holes for the rod that is spring loaded by a compression spring relative to one of the brackets with the possibility of interacting the lower end with the radial hole of the plate and moving up and down which is mounted on the pipe surface such that the shaft axes, compression springs, holes of the brackets, the axis of the opening of the fixing element in the extreme open position of the swivel bla
