But if your lawn feels spongy or you notice more than 1 inch of thatch, it\u2019s time to dethatch. In areas with heavy foot traffic or compacted soil, annual dethatching might be necessary.<\/p>    <p class=\"wp-block-paragraph\"><strong>Tip<\/strong>: <strong>Kentucky bluegrass and creeping red fescue<\/strong> are more prone to thatch buildup due to their rhizomes.
