Alright, what do you guys think about spot treating weeds on all visits to a lawn each year, as opposed to the big company approach of blanket weed control sprays in the spring and fall. Please comment on the effectiveness of keeping the weeds out when spot treating each time you fertilize, versus the blanket weed spray. Last year a did a blanket spray in the spring and fall and it handled the weeds good, but I'd like to try and introduce a little IPM and save on pesticide cost by spot spraying. To me it just doesn't make sense to spray a whole lawn that is in good shape, unless it's a new customer with a weedy lawn. I think this is a waste of product. Has anyone been burned not doing a blanket spray and spot treating weeds as necessary each round instead? Lets get a good thread going here.
