I have to imagine there was a time long before Target, Wal-Mart, Lowe’s, Home Depot and all of these mega-retailer stores that if you wanted something like grass seed, you walked into the local store and there were two choices; a 20 lb. bag and a 50 lb. bag. Make your selection and go home. And it probably worked fine for covering up those bares spots on the lawn where your dog keeps peeing and killing the grass. My lawn has more yellow spots than a salamander. When we go to one of the previously mentioned mega-retailer stores they have more grass seed choices than I can stand. They don’t, however, have the one kind of grass seed I would buy without hesitation.
