Abstract: A tomato cage is provided which can be quickly and easily assembled with no tools at all, or merely a pair of pliers. When disassembled it can be stored in a minimum space, and since there are very few different components, it can be manufactured in a simple manner. A plurality of vertical support posts are disposed at the corners of a polygon; e.g. four support posts are disposed at the corners of a square. Rods interconnect the support posts, apertures being formed in the support posts for receiving a first end of a rod. Only one type of rod need be utilized, having a generally straight first end and having a hook at a second end, each rod extending from an aperture in one post to a position wherein the hook engages another rod adjacent the second post, and so that each rod makes an angle in the range of about 5.degree.-10.degree. with respect to the horizontal.
