TruGreen had my lawn looking lush and green in just a season or two, and that was starting from a lawn that was patchy, weed-ridden, and being taken over by moss and violets. Even though they could not guarantee complete control of the moss and violets without special attention, the moss and violets disappeared almost entirely by the 2nd season of regular lawn treatments. My lawn is now like an outdoor carpet..... lush, green, and no weeds. They also call a day or two ahead of time, so that you have time to get the lawn cleared of toys, etc. The annual price is reasonable for all of this.
