Yesterday was our 7th and final visit from Spring-Green to fertilize our lawn. They applied the 21-0-0 "Winterizer." The note says, "This will provide your lawn with the nutrients it needs to say healthy over winter."
I do have to say that I am pleased with the decision to hire my lawn fertilization out. Yes, it was more expensive than doing it myself, but it looks waaaaaay better than when I tried to do it myself. Plus I never really knew what I was doing, and I couldn't be depended on to do it when it needed it. So I'm glad we opted to go this route. I would imagine we will have them service our lawn next year too. No complaints.
