A collapsible and height-adjustable plant shade is an apparatus that readily extends and retracts around a plant or multiple plants in order to protect the plant or multiple plants from extreme weather. The apparatus includes a scaffolding and a mesh covering. The scaffolding includes a plurality of length-adjustable legs, a collapsible lateral frame, and a roofing frame. Each of the plurality of length-adjustable legs may vary in height in order to accommodate uneven terrain. The collapsible lateral frame connects the plurality of length-adjustable legs with each other and mounts the roofing frame onto the plurality of length-adjustable legs. The mesh covering encloses the scaffolding and shields the plant or multiple plants. The apparatus further includes a plurality of extension lateral panels in order to account for any distance between the mesh frame and the ground due to varying heights of each of the plurality of length-adjustable legs.
