1 <br /> Whether in landscape or right -of -way situations, cultural needs of <br /> the desirable plant materials (drainage, soil fertility, mowing, mulching, <br /> pruning, etc.) also must be adequately met if weed and pest - control <br /> intervention is to be minimized. Healthy, vigorous well- adapted plants are <br /> 1 better able to out - compete undesirable vegetation such as invasive noxious <br /> 1 species. <br /> You may know of a turfgrass area or roadside backslope, for <br /> 1 example, that receives only sporadic mowing (at best), little or no fertilizer, <br /> and almost no other attention, but is sprayed annually (or every few years) <br /> to control brush or reduce broadleaf weed populations. Experience has <br /> proven that diligent attention to the neglected cultural measures and timely <br /> low- volume spot treatments can easily hold invasive woody plants and <br /> broadleaf weeds below "threshold" levels, eliminating the need for <br /> 1 comprehensive herbicide applications. <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> 10 <br /> 1 <br />
