Winter Planter Protection Kit for Small Gardeners

Many urban or small-space gardeners want to extend their growing season but lack space or knowledge for greenhouses. A compact, easy-to-assemble kit for insulating and covering small above-ground planters would solve this. It could include insulated sides/bottom, a mini-hoop frame with clear plastic sheeting, and instructions for cold-weather crop selection. This targets a specific need for small-scale winter gardening in colder climates.
