Abstract/Contents:"Weed control is an essential component of any ornamental production system. Much data exists to document the impact that weeds have on agronomic, vegetable and fruit corps. Less information is available on the influence that weeds have on woody ornamental species. Although the tools are now available to nurserymen to produce many ornamental species in an essentially bareground, weed-free environment, there are possible benefits to maintaining a permanent or semipermanent ground cover of weeds and/or cover corps. A field study was established in 1986 at the Long Island Horticultural Research Lab to examine the effect that several weed and ground cover management systems have on the growth and development of woody ornamental species. The treatments examined the competitive effect of annual broadleaf weeds, grassy weeds and tall fescue (Festuca arundinacea 'K31') as influenced by mowing, cultivation and percent ground cover. Directed applications of paraquat, within a one meter strip in the row, were used to establish a 50% ground cover regime in the plots. The weedy grass and broadleaf treatments were maintained by periodic directed applications of the selective herbicides bentazon and sethoxydim. Taxus (Taxus media), Green ash (Fraxinus pennsylvannica) and White Pine (Pinus strobus) were the three species which were the most successfully established of the six planted. Of these, Green Ash exhibited the greatest response to the treatments. Plant height was significantly reduced where vegetation was allowed to completely cover the ground, regardless of the type (grasses, broadleaf, tall fescue) and maintained weedfree within the row. The growth of the two evergreen species was slower and treatment effects were less evident although it appears that they were less adversely affected by weed competition than was Green Ash."
