Weed Control in the Landscape

Abstract

Weeds typically found in the landscape are classified as either annuals or perennials. Annual weeds such as crabgrass or purslane are relative- ly easy to keep under control by either mulching, cultivation, hand pulling, pre-emergence her- bicides or a combination of two or more of these methods. Perennial weeds such as bindweed or nutsedge are much more difficult, if not almost im- possible, to control by the above methods due principally to their extensive root systems. Weeds can be controlled prior to or after planting, however, many landscape operators fail to recognize the importance of eliminating weeds, especially perennials, prior to planting
