PROBLEM TO BE SOLVED: To provide a device for supporting the growth posture, etc., of a cultivated plant capable of providing a large and long range for making an amendment for correcting a flower stalk of the cultivated plant into an upward directed posture by pulling effective, usable for a long period according to the growth of the cultivated plant, simply and rapidly performing operations to amend the growth posture, etc., of the flower stalk and correct the growth posture, etc., into the upward directed posture. SOLUTION: This device for supporting the growth posture, etc., of a cultivated plant comprises one long slender wiry body 12 having an engaging part 14 for freely detachably engaging or disengaging a rope, etc., for hanging and supporting a flower stalk part of the cultivated plant on one end side thereof and further an elastic bent part 16 having a reactional force capable of bending the wiry body 12 into a two-folded state and returning the wiry body 12 into a nearly linear state in the intermediate position in the longitudinal direction of the wiry body 12 and supporting the other end side on a supporting pipe applied to a pot seedling of the cultivated plant. The device has a high freedom of a pulling up angle of the flower stalk to the upper side and is capable of surely elastically pulling up and pulling the flower stalk even if the flower stalk of the cultivated plant is downwardly directed or variously deformed.
