A plant support apparatus and related method for supporting a plant are disclosed. The plant support apparatus includes a first support layer including a first plurality of support arms having first ends and second ends. The first ends are coupled at a corresponding plurality of first support junctions and the second ends are coupled at a corresponding plurality of second support junctions. A second support layer includes a second plurality of support arms having first ends and second ends. The first ends are coupled at a corresponding plurality of third support junctions and the second ends are coupled at a corresponding plurality of fourth support junctions. The second and third support junctions are selectively coupled for concurrent movement. Subsequent layers of support are sequentially added to accommodate and support the plant as it grows.
