Abstract
Abstract A mulch comprises a paper sheet covered substantially completely on one side thereof with a water-impervious material and treated at marginal regions only of the opposite side thereof with a water-insoluble fungicide. The marginal regions of the mulch may be treated as the mulch is fed from a supply roll and laid upon the ground, with the water-impervious side facing downward. The treated marginal regions are covered with soil to anchor the mulch and to provide a long-term mulch without substantial deterioration.
