There is only two good reasons to dethatch a lawn.<br>1- If the leaves were not cleaned up at all last fall, especially in a weak lawn, you may save time on spring cleanup by running a powerrake over the lawn, then cleaning it.<br>2- In a lawn with very excessive thatch, you can aerate in 3 to 4 directions. Since this would have 8-10% of the actual thatch sitting on thr surface, a powerraking would enable you th remove this quantity of thatch, while leaving the soil from the plugs on the lawn.<p>Dethatching, or powerraking is generally done as a spring cash generator. You churn up and haul away a tremendous amount of material, so the customer just knows you are doing something great. And since it is so impressive, you can charge a pretty penny for it. Lazer stated it simply above.<p>"Dethatching" is not removing thatch. It is mostly pulling up a lot of dead grass that would decay in the next 6 weeks on its own.<p>----------<br>Jim<br>North central Indiana
