Wait 24-48 hours after rain or irrigation to prevent clumping and soil compaction.<\/li>    <li><strong>Mow at the highest setting:<\/strong> Set your blade to remove only the top one-third of grass length. Higher mowing encourages deeper root growth.<\/li>    <li><strong>Leave clippings on the lawn: <\/strong>Skip the grass catcher for the first few mows.

If you overseed KBG with ryegrass, you may be able to mow it as soon as <strong>2 weeks after overseeding<\/strong>, provided the new grass reaches 3 to 4 inches tall.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1767935870316\"><strong class=\"schema-faq-question\">Can I Walk on Grass After Overseeding?<\/strong> <p class=\"schema-faq-answer\">Minimize foot traffic for around 3-4 weeks after overseeding.
