A garden protection system includes a frame operable to suspend a shade cloth over a garden bed to protect underlying plants in the garden bed from inclement weather, and a housing mounted to the frame and comprising a moisture detector, a roller system, circuitry, a motor, a pulley system, a power supply, and a solar panel. The shade cloth is wrapped about the roller system, and the roller system is rotatably coupled to the pulley system. The moisture detector is operable to detect said inclement weather, and to automatically direct the motor to rotate the pulley system. And, the pulley system is operable to rotate the roller system to roll the shade cloth along a side of the garden protection system via roller brackets that are slidably affixed to the frame.
