Abstract: A rod like plant support is held in a plant pot adjacent the side wall of the latter. The holder is in the form of a flat discoid base plate, with an integral socket upstanding from a central portion thereof. A rod engages into and upstands from the socket. A number of integral fingers radially outwardly project from the discoid base plate generally within its plane. The length of each finger is adjustable to fit plant pots having varying internal diameters or varying configurations. Preferably, length adjustment of the fingers is made by cutting end portions thereof along transverse weak lines. In this way, not only is the plant support immobilized within the plant pot, but also, the relative position of the upstanding tie-rod is adjustable relative to plant foliage configuration.
