Having problem with coverage on rain bird's spray heads. The areas that are effected are not getting enough water (I believe) due to the arc of the spray. What I am try to say is there are areas, not in shade, (we are in a drought so this could influence the areas) that are not getting water. The areas are near the heads so i think the spray is going over them not reaching those close areas. Any suggestions for different spray types or does the soil need to be treated in those dry areas? I believe it is just sun damaged because of the drought and the areas soil needs to be treated... What do you think?
