ABSTRACT:
This invention permits a gardener to establish garden borders and to trim lawn edges simply with use of chemical herbicides thereby eliminating the need for edge trimmers or edge trimming spades. Thus, a hood accessory is provided for attachment to a hand held sprayer to conform spray from its spray head to a desired variable line width, Thus, for example, the sidewalk edge of a lawn need not be mechanically cut, but can be controlled by confining a herbicide flow pattern to a narrow line alongside the sidewalk. Similarly trimming the edges of flower or shrub gardens is feasible without the danger of killing the flowers or shrubs with herbicide. A low-price flexible walled plastic hood is thus fashioned for fitting onto the spray head. An adjustable mechanism then flexes the walls to produce a spray line width of the dimensions desired. All herbicide is thus prevented by the hood from being carried by the spray head or the wind into adjacent grass, shrubbery or flowers.
