You can use a core aerator that removes soil plugs, a manual aerator for small yards, or hire a professional service.<\/p>    <p class=\"wp-block-paragraph\">The process takes 1 to 3 hours, depending on lawn size and method, and works best when your grass is actively growing. That means late spring or early summer for warm-season grasses and late summer to early fall for cool-season grasses.<\/p>    <p class=\"wp-block-paragraph\">This guide walks you through the whole aeration process, from choosing the right equipment to the post-aeration care that makes your effort pay off.<\/p>    <figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Need professional help?<\/strong> LawnStarter&#8217;s experts handle <a href=\"https:\/\/signup-web.lawnstarter.com\/cart\/contact-info?intent=aeration\">aeration<\/a>, or you can bundle <a href=\"https:\/\/signup-web.lawnstarter.com\/cart\/contact-info?intent=aerationOverseedingPackage\">aeration with overseeding services<\/a>.<\/td><\/tr><\/tbody><\/table><\/figure>    <figure class=\"wp-block-table is-style-stripes has-medium-font-size\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>Key Takeaways<\/strong><\/th><\/tr><\/thead><tbody><tr><td>\u2022 Core aerators work best, pulling 2-3 inch soil plugs that relieve compaction.<br>\u2022 Aerate in late spring for warm-season grass or early fall for cool-season grass.<br>\u2022 Keep soil moist but not muddy, leave the plugs to break down, then fertilize and overseed.<\/td><\/tr><\/tbody><\/table><\/figure>   <div class=\"wp-block-ub-table-of-contents-block ub_table-of-contents\" id=\"ub_table-of-contents-f49fa9ed-4508-4e63-9ea4-eb216fa6f7f1\" data-linktodivider=\"false\" data-showtext=\"show\" data-hidetext=\"hide\" data-scrolltype=\"auto\" data-enablesmoothscroll=\"false\" data-initiallyhideonmobile=\"false\" data-initiallyshow=\"true\"><div class=\"ub_table-of-contents-header-container\" style=\"\"> \t\t\t<div class=\"ub_table-of-contents-header\" style=\"text-align: left; \"> \t\t\t\t<div class=\"ub_table-of-contents-title\" style=\"\">In this article:<\/div> \t\t\t\t \t\t\t<\/div> \t\t<\/div><div class=\"ub_table-of-contents-extra-container\" style=\"\"> \t\t\t<div class=\"ub_table-of-contents-container ub_table-of-contents-1-column\"> \t\t\t\t<ul style=\"\"><li style=\"\"><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-aerate-lawn\/#0-choosing-your-aeration-method\" style=\"\">Choosing Your Aeration Method<\/a><\/li><li style=\"\"><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-aerate-lawn\/#2-preparing-your-lawn-for-aeration\" style=\"\">Preparing Your Lawn for Aeration<\/a><\/li><li style=\"\"><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-aerate-lawn\/#3-how-to-aerate-your-lawn-step-by-step\" style=\"\">How to Aerate Your Lawn: Step-by-Step<\/a><\/li><li style=\"\"><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-aerate-lawn\/#8-after-aeration-next-steps\" style=\"\">After Aeration: Next Steps<\/a><\/li><li style=\"\"><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-aerate-lawn\/#11-troubleshooting-common-problems\" style=\"\">Troubleshooting Common Problems<\/a><\/li><li style=\"\"><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-aerate-lawn\/#15-signs-your-lawn-needs-aeration\" style=\"\">Signs Your Lawn Needs Aeration<\/a><\/li><li style=\"\"><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-aerate-lawn\/#16-when-should-you-aerate-your-lawn\" style=\"\">When Should You Aerate Your Lawn?<\/a><\/li><li style=\"\"><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-aerate-lawn\/#17-when-to-hire-a-professional\" style=\"\">When to Hire a Professional<\/a><\/li><li style=\"\"><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-aerate-lawn\/#18-faqs\" style=\"\">FAQs<\/a><\/li><\/ul> \t\t\t<\/div> \t\t<\/div><\/div>   <figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Project Difficulty:<\/strong> Easy to intermediate<br><strong>Estimated Time to Complete:<\/strong> Manual aeration can take up to 60 minutes per 1,000 sq. ft., while core aeration can take 30 minutes to 1.5 hours for lawns up to 1\/4 acre.<br><strong>Project Cost:<\/strong> Renting aeration equipment costs around $100 per day.
