Evaluation of Landscape Fabrics in Suppressing Growth of Weed Species

Abstract

Two tests were conducted to evaluate weed penetration up through landscape fabrics. The degree of weed suppression varied depending on the specific landscape fabric. No landscape fabric gave total suppression of weeds tested. Sicklepod ( Cassia obtusifolia L.) and smallflower morningglory ( Jacquemontia tamnifolia ( L. ) Grisebach .) were inhibited by all landscape fabrics. Growth of pigweed ( Aranthus sp.), bermudagrass ( Cynodon datylon ( L .) Persoon .), yellow nutsedge ( Cyperus esculentus L .), and johnsongrass ( Sorghum halepense ( L .) Persoon .) was suppressed by certain landscape fabrics.
