I have a large lawn that has some broad-leaf weeds (e.g. dandelions) and
a few spots with thinning grass. At Walmart and Target I see bags of
lawn additives like Weed & Feed and Turf Builder. Will spreading one of
those products result in a more attractive lawn? Any better
alternatives? Do I have to spread lawn seed too? I live in Western
Washington state. Thanks for any advice. Mike
