ABSTRACT:
A plant protection system which is economical, and quickly installed and removed and which can be used on row crops such as strawberries to protect against frost, freezing, and insects. The system includes a series of frames placed along a crop row wherein each frame has at least one twine engaging loop on the upper portion of the frame. Twine is tensioned along the upper sides of the frames by drawing the twine into an open end of the loop, looping the twine completely around the loop and proceeding to the next frame with the twine held in tension at the loop. A protective cover is draped over the frames and tensioned twine and anchored in the crop furrows. The tension of the twine between the frames prevents the cover from sagging and touching the crops.
