Just starting out this year (was only planning on mowing) and called for my business insurance (Illinois). The guy told me the price for mowing only and was shocked to find out that it was the same price for "Landscaper" catagory (fertilizing and spraying). I used a 200 gal. skid mount in iowa and covered the "whole yard" before. I would like to go to a back pack unit and more or less treat weeds only where they are growing. My questions are: 1: Who has a similar setup where they do not spray @ 2 gal per 1000/sf? out of a larger tank 2: Do you move a majority of problems (fungus, grubs, etc) to a broadcast granular applications? I would like to have a couple of 4 gal tanks (backpack) on the truck and a 30 gallon water supply. fertilize the yard and then only spot spray the problem areas with the right pesticide. I was planning on using the Justmowit philosophy and thrive on volume (most LOT sizes are 6,000 to 8,000 SF), but this throws a wrench into that plan. Thanks for any advice/tips. Gotta study for my test now!
