1. In early spring apply a fertilizer with Halts in it. this will fertilize your lawn while preventing crab grass growth.
2. In early spring top your lawn (cut short dead growth) and rake up as much death grass as possible (this is the hardest part).
3. In early spring apply granulated or liquid Revive, which is a surfactant which allows the water to penetrate and green up your lawn.
4. Start watering your lawn if you live in a dry area such as Colorado. Folks, grass does not grow without water.
5. Fertilize about every three to four weeks.
6. Mow regularly, and don't mow too short!
7. When you mow, bag the clippings. Too much thatch smothers the lawn.
8. Apply weed and feed when necessary.
9. Apply and insecticide when necessary. (I only use spot weed killers)
10. Edge around your sidewalks.
Do you think this is a lot of work? It take me an average of 30 minutes a week to care for my lawn, and it looks great. Yes, I have a front yard and a back yard. The first yard cleanup in the spring takes the longest. After that, it's a breeze.
Oh, and notice I did not suggest aeration. I have never aerated and my lawn is the best in the subdivision.
Now, make a pot of coffee and sit on your deck or your porch and enjoy your yard.
