Abstract: A folding support stand is used to hold up growing plants. The stand has a pair of matching support frames each having a pair of legs interconnected by at least one beam member. The support frames are connected for pivotal movement between and open position for use and a closed position for storing, and a catch is provided to prevent this pivotal motion. Here the legs on each frame may form a scissor assembly with a leg on the other frame. At least one trellis piece is disposed on and supported by each support frame. In the embodiments, two beams and a plurality of trellis pieces are associated with each support frame. The trellis pieces can be slats or serpentine wire members. The catch can be variable so that the acute angle between the support frames can be changed, as desired.
