ABSTRACT:
The present invention relates to a dual-ply fumigation and plant bed cover including an imperforated plastic type cover that acts to effectively seal a plant bed during fumigation and a cloth type cover for providing basic plant protection during the early growth of plants within the covered plant bed. The plastic type cover is stitched to the cloth type cover about a tear seam in order that at a selected time the plastic type cover can be torn or stripped away from the cloth type cover, leaving the cloth type cover stretched over the plant bed. To form the tear seam, a tape cloth strip is secured over the plastic layer about each side, and stitches are sewn through the tape cloth, plastic, and cloth layers. As a part of the method of the present invention, as disclosed herein, after seeding, the plastic type cover may remain intact with said cloth type cover until seed germination, so as to effectively expedite seed germination because of a greenhouse effect realized by the plastic type cover.
