Dethatch & aerate
Thatch is a layer of dead organic matter, such as stems, roots and clippings, that are between the soil's surface and the grass. A little thatch will not harm your lawn, but if it excedes a half inch, it is time to take some action. Sometimes, before we de-thatch a lawn with a power rake, we recommend to apply moss and/or weed control, depending on the lawn conditions. After we rake off all the thatch and/or dead moss, we reseed, using the appropiate mix of seeds (mainly Perennial Ryegrass, Kentucky Bluegrass and Fescue) recommended for the Pacific Northwest zone and finally, we add the proper fertilizer and top dress to the lawn with certified organic compost.
Due to the amount of rain in the Pacific Northewest, is highly recommended to aerate or core your lawn at least once a year (some of my customers have it done twice a year and the results are noticeable). We use a power aerator to punch holes in the ground and pull out small cores of lawn and soil (a small fingerlike core). Aerating your lawn reduces ground compaction and minimizes thatch, helping the roots to better reach water and oxygen.
