Abstract: An expandable framework, with attachable plant-support trays, is provided for installation within an interior window frame. One embodiment of the framework is expandable to a fixable height in a vertical direction and expandable in a horizontal direction via upper and lower telescoping tube pairs to accommodate a range of common window sizes. A pair of spacer sticks are provided, which can be cut to appropriate lengths so that one spacer stick and an associated coil spring can be inserted within each telescoping tube pair so that the frame assembly can be biased against opposed vertical portions of the window frame in the interior of a building. A plurality of tray support arms, each of which has a square aperture or receptacle, can be rotationally locked onto each telescoping tube pair for the support of a plant support tray.
