My lawns have been the best on the block as a result of Gary's Lawn Service, and his use of polymer crystals! I didn't use him, one year, and sorely regretted it! If you research the cost of polymer crystals, they are VERY expensive; thus the cost.I asked my lawn people if they could add them and the cost was exhorbitant because they don't stock them, or buy in bulk, like Gary does. Personal choice, of course. But only if you want a fabulous lawn! The reviews found here seem to be based on cost; my lawn is worth every dime with Gary!
