In the spring, the thatcher is the first thing to use…….or hand rake….. ………you want to pick all the dead stuff left over from fall and winter.
Aeration is usually done in the fall. And it all depends on how much traffic your lawn gets…..if it shows signs of compaction, then by all means, give it a conditioning with the aerator.
As far as the roller……..some lawns don’t need it, others do, and probably only once a year to once every other year. If you have big dips in the lawn. you want to mix up some peat moss and topsoil, mix it together and fill in the dips, about 1 -2 inches at a time, maybe have to hit an area more that once to level it…….but the roller is good for mole runs, or just a lumpy feeling lawn. But be careful and don’t overdo it, or you will compact it…..and then you can aerate The best time to run a roller is a day after a rain, when the ground is soft, but not too wet. (again….compaction is not a good thing)..
Not an expert by any means……..but little brother is a Master Gardner, and I go to him for any words of wisdom, and he has helped me get my lawn in better shape.
