When aerating your lawn, it is best to aerate on a day where the temperatures are milder and the soil in a moist condition, which will make the aerating process much easier. Aerating wet soil can be a real nuisance due to the fact that the plugs will get stuck in the hollow tines and can further compact you soil.
Once you determine that you need to dethatch your lawn, the next step is to figure out how. As previously stated in the section on aerating, aerating can be a better alternative to dethatching if your lawn does not have excessive amounts of thatch (usually 1 inch or less). Once you are finished, be sure to remove all thatch and debris from your lawn. 2  Unlike aerating, dethatching is almost strictly for the removal of thatch and debris. 3  Removal can usually be done with a simple leaf rake. 4  Once your lawn is dethatched, it is usually a great time to fertilize your lawn and/or reseed it.
