PURPOSE: A multi-stage assembling flowerpot is provided to conveniently move by configuring to easily assemble and dismantle, to water the flowerpot conveniently, and to dismantle the flowerpot into the portable size of parts. CONSTITUTION: A multi-stage assembling flowerpot comprises support legs(10) supporting on the ground； vertical connection rods(20) connecting vertically by a certain height above the supporting legs； water saucer supports(30) mounted on the top of the support legs, in which a center insertion hole(31a) to be inserted into the vertical connection rod is formed； multiple flowerpot fixing devices(40) which are inserted to the outside of the vertical connection rod, arranged with a predetermined height interval and fixed； multiple flowerpots(50) consisting of a combined pair of a first side flowerpot(51) and a second side flowerpot(52), which have an inner space with predetermined depth respectively and are combined to the outside of the vertical connection rod in a detachable manner； and a horizontal supporting bar(60) with a branched connection hole which is inserted to the top end of the vertical connection rod and branched in the horizontal direction. The flowerpot is formed with sidewalls(51a) in order to form an inner space of the first side flowerpot and the second side flowerpot respectively, each insertion hole(51b,52b) which is inserted to the outside of the vertical connection rod, insertion projections(51c,52c) and fitting grooves(51d, 52d) corresponding to each other in the position where the sidewalls are adjacent to be assembled each other and dismantled. Multiple drain holes(51e, 52e) are formed on the bottom of the inner space of the first side flowerpot and the second side flowerpot, respectively. The support legs comprises distant standing parts(11) which are formed to be curved toward the center direction from the four directions, horizontal base parts(12) which are extended from the distant standing parts and are formed to be
