Behind every healthy stretch of grass lies healthy soil \u2014 soil that breathes, absorbs water efficiently, and allows roots to spread deep. Lawn aeration is one of the most important, yet most commonly overlooked, maintenance practices that makes all of this possible. Whether your yard is showing signs of stress or you simply want to keep it thriving year after year, understanding what lawn aeration is and why it matters can transform the way you care for your outdoor space.<\/p>\n<p>The problems that aeration solves are often hiding in plain sight. You might notice water pooling after rain, patches of grass that refuse to fill in, or a lawn that feels unusually hard underfoot. These are all signals that the soil beneath your turf is struggling. Lawn aeration directly addresses the root causes of these issues \u2014 literally and figuratively \u2014 by opening up pathways for air, water, and nutrients to reach the grass roots where they are needed most.<\/p>\n<p>This article covers everything homeowners need to know about lawn aeration: what it means, why it matters, how to recognize when your lawn needs it, and how to get the best results from the process.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_81 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/plant.tipkerja.com\/info\/lawn-aeration-importance\/#What_Lawn_Aeration_Actually_Means\" >What Lawn Aeration Actually Means<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/plant.tipkerja.com\/info\/lawn-aeration-importance\/#Why_Lawns_Struggle_Without_Aeration\" >Why Lawns Struggle Without Aeration<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/plant.tipkerja.com\/info\/lawn-aeration-importance\/#The_Main_Benefits_of_Aerating_a_Lawn\" >The Main Benefits of Aerating a Lawn<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/plant.tipkerja.com\/info\/lawn-aeration-importance\/#Signs_Your_Lawn_May_Need_Aeration\" >Signs Your Lawn May Need Aeration<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/plant.tipkerja.com\/info\/lawn-aeration-importance\/#When_to_Aerate_for_the_Best_Results\" >When to Aerate for the Best Results<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/plant.tipkerja.com\/info\/lawn-aeration-importance\/#How_Lawn_Aeration_Is_Done\" >How Lawn Aeration Is Done<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/plant.tipkerja.com\/info\/lawn-aeration-importance\/#What_to_Do_After_Aerating\" >What to Do After Aerating<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/plant.tipkerja.com\/info\/lawn-aeration-importance\/#Common_Aeration_Mistakes_to_Avoid\" >Common Aeration Mistakes to Avoid<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/plant.tipkerja.com\/info\/lawn-aeration-importance\/#Conclusion\" >Conclusion<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-10\" href=\"https:\/\/plant.tipkerja.com\/info\/lawn-aeration-importance\/#References\" >References<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"What_Lawn_Aeration_Actually_Means\"><\/span>What Lawn Aeration Actually Means<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure><img decoding=\"async\" src=\"https:\/\/plant.tipkerja.com\/info\/wp-content\/uploads\/2026\/06\/img_1781419947706_2_x82rpnuf4qo.webp\" alt=\"What Lawn Aeration Actually Means What Is Lawn Aeration and Why Is It Important?\" width=\"600\" height=\"400\" loading=\"lazy\"><figcaption>What Lawn Aeration Actually Means What Is Lawn Aeration and Why Is It Important?. Image Source: pexels.com<\/figcaption><\/figure>\n<p>Lawn aeration is the process of creating small openings in the soil to relieve compaction and improve the movement of air, water, and nutrients into the root zone. The most effective and widely recommended method is <strong>core aeration<\/strong>, also called plug aeration or core aerification. A core aerator uses hollow tines to pull out small cylindrical plugs of soil \u2014 typically about 0.5 to 0.75 inches in diameter and 2 to 3 inches deep \u2014 at regular intervals across the lawn surface.<\/p>\n<p>These removed cores are left on the surface, where they break down naturally within one to two weeks. As they decompose, the soil microbes in the plugs help integrate organic matter back into the lawn, steadily improving soil structure over time.<\/p>\n<h3>Core Aeration vs. Spike Aeration<\/h3>\n<p>It is important to distinguish core aeration from spike aeration, which simply pokes holes into the ground without removing any soil. Spike tools \u2014 including handheld pitchfork-style aerators and spike-sandal attachments \u2014 do create holes, but they can actually increase compaction around the hole walls rather than relieving it. According to guidance from <strong>Clemson Cooperative Extension<\/strong>, core aeration is far more effective because it physically removes material, making room for the soil structure to open up and breathe properly.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_Lawns_Struggle_Without_Aeration\"><\/span>Why Lawns Struggle Without Aeration<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure><img decoding=\"async\" src=\"https:\/\/plant.tipkerja.com\/info\/wp-content\/uploads\/2026\/06\/img_1781419966876_1_d17yf13gfl8.webp\" alt=\"Why Lawns Struggle Without Aeration What Is Lawn Aeration and Why Is It Important?\" width=\"600\" height=\"400\" loading=\"lazy\"><figcaption>Why Lawns Struggle Without Aeration What Is Lawn Aeration and Why Is It Important?. Image Source: unsplash.com<\/figcaption><\/figure>\n<p>Soil compaction is the primary reason most lawns benefit from regular aeration. Compaction occurs when soil particles are pressed tightly together, leaving little room for the air pockets and pore spaces that roots, water, and gas exchange depend on. This is a gradual process that can happen even in well-maintained yards that receive regular watering and fertilization.<\/p>\n<h3>Common Causes of Soil Compaction<\/h3>\n<p>Several everyday factors cause soil to become compacted over time:<\/p>\n<ul>\n<li><strong>Heavy foot traffic<\/strong> \u2014 children, pets, and regular lawn use compact the top layer of soil with repeated pressure, especially in frequently traveled areas of the yard.<\/li>\n<li><strong>Clay-heavy soils<\/strong> \u2014 clay particles pack densely and drain poorly, making compaction significantly worse in these soil types compared to sandy loam or well-amended garden beds.<\/li>\n<li><strong>Heavy lawn equipment<\/strong> \u2014 riding mowers and other machinery press down on the soil surface repeatedly throughout each growing season.<\/li>\n<li><strong>Natural settling<\/strong> \u2014 even without significant traffic, soil compacts gradually as rain and gravity press particles closer together year after year.<\/li>\n<\/ul>\n<h3>The Problem of Thatch Buildup<\/h3>\n<p>Closely related to compaction is <em>thatch<\/em> \u2014 the dense layer of decomposing grass stems, roots, and organic debris that accumulates between the green grass blades and the soil surface. A thin thatch layer under half an inch is normal and even beneficial, acting as a light mulch. When it exceeds that threshold, it begins to block water, air, and fertilizer from reaching the soil below.<\/p>\n<p>According to the <strong>University of Missouri Extension<\/strong>, core aerification helps manage thatch by introducing soil microbes from the extracted cores into the thatch layer, speeding up its natural breakdown. Without periodic aeration, thatch can accumulate into a substantial barrier that fertilizers, rainfall, and irrigation cannot reliably penetrate, no matter how faithfully you apply them.<\/p>\n<h3>Shallow Root Systems<\/h3>\n<p>When soil is compacted and thatch is thick, grass roots are forced to remain shallow rather than growing down into the deeper soil profile. Shallow roots mean the lawn is far more vulnerable to heat stress, drought, and disease. A lawn with shallow roots cannot access the water and nutrients stored deeper in the soil, and it is the first to show brown, stressed patches during a hot or dry stretch of weather.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Main_Benefits_of_Aerating_a_Lawn\"><\/span>The Main Benefits of Aerating a Lawn<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When done correctly and at the right time, lawn aeration delivers a range of improvements that touch nearly every aspect of grass health. The benefits compound significantly when aeration is paired with complementary practices like overseeding and fertilizing.<\/p>\n<ul>\n<li><strong>Improved air exchange<\/strong> \u2014 oxygen-starved soil opens up, allowing carbon dioxide produced by roots and soil organisms to escape and fresh oxygen to enter the root zone where it supports biological activity.<\/li>\n<li><strong>Better water infiltration<\/strong> \u2014 water moves through aerated soil more efficiently, reducing surface runoff and the risk of puddling after rainfall or irrigation cycles.<\/li>\n<li><strong>Enhanced nutrient uptake<\/strong> \u2014 fertilizers and soil amendments applied after aeration reach the root zone directly through the open channels, making them significantly more effective per application.<\/li>\n<li><strong>Deeper root development<\/strong> \u2014 roots no longer blocked by compacted soil can grow downward into the profile, creating a stronger, more drought-resistant lawn that recovers quickly from stress periods.<\/li>\n<li><strong>Improved turf density<\/strong> \u2014 when paired with overseeding, aeration provides excellent seed-to-soil contact, improving germination rates and filling in thin or bare patches across the lawn.<\/li>\n<li><strong>Greater stress tolerance<\/strong> \u2014 a well-aerated lawn with deep roots handles temperature extremes, concentrated foot traffic, and seasonal drought far better than a compacted, shallow-rooted counterpart.<\/li>\n<\/ul>\n<p>Research from <strong>NC State Extension&#8217;s Carolina Lawns<\/strong> guide notes that core aeration is particularly effective ahead of overseeding, as the open holes dramatically improve seed-to-soil contact \u2014 the single most important factor in germination success for both cool-season and warm-season grass varieties.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Signs_Your_Lawn_May_Need_Aeration\"><\/span>Signs Your Lawn May Need Aeration<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Not every lawn needs to be aerated every single year, but certain signs clearly point to the need. Recognizing these indicators early allows you to address compaction before it causes lasting damage to your grass and soil structure.<\/p>\n<h3>Physical and Visual Clues<\/h3>\n<ul>\n<li><strong>Water puddles after rain<\/strong> \u2014 if water sits on the lawn surface for more than a few minutes rather than soaking in, compaction may be preventing proper infiltration.<\/li>\n<li><strong>Hard soil underfoot<\/strong> \u2014 try pressing a screwdriver or pencil into the soil. If it is difficult to push in more than two inches, the soil is very likely compacted and overdue for aeration.<\/li>\n<li><strong>Thinning or bare patches<\/strong> \u2014 areas where grass refuses to grow or looks persistently patchy despite regular watering and fertilizing often signal compacted or thatch-blocked soil just beneath the surface.<\/li>\n<li><strong>Spongy or bouncy surface<\/strong> \u2014 a lawn that feels unusually cushiony underfoot may have excessive thatch, which acts like a thick sponge separating grass blades from the soil below.<\/li>\n<li><strong>Poor recovery after heat or drought<\/strong> \u2014 grass that stays brown or struggles to green up after a dry period may have shallow roots caused by long-term soil compaction limiting downward root growth.<\/li>\n<\/ul>\n<h3>High-Traffic Problem Areas<\/h3>\n<p>Lawns that see regular, concentrated foot traffic \u2014 paths to a garden gate, children&#8217;s play areas, or routes that pets run daily \u2014 are especially prone to localized compaction. These zones often benefit from more frequent aeration than the rest of the lawn, and sometimes warrant targeted spot treatment between full lawn aeration cycles to keep those areas open and healthy.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"When_to_Aerate_for_the_Best_Results\"><\/span>When to Aerate for the Best Results<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Timing is one of the most critical factors in getting aeration right. The guiding principle is to aerate during the grass&#8217;s period of <strong>active growth<\/strong>, when the turf can recover quickly, fill in the holes left by the aerator tines, and take full advantage of the improved soil conditions below.<\/p>\n<h3>Cool-Season Grasses<\/h3>\n<p>Cool-season grasses such as Kentucky bluegrass, tall fescue, and perennial ryegrass grow most vigorously in spring and fall. <strong>Early fall<\/strong> \u2014 typically late August through October depending on your climate zone \u2014 is considered the optimal window for aerating cool-season lawns. The soil is still warm enough to support active root growth, and the cooler air temperatures promote grass recovery while discouraging weed seeds from germinating in the freshly opened cores. Early spring is a workable secondary window, though fall is generally preferred for the combination of recovery conditions it provides.<\/p>\n<h3>Warm-Season Grasses<\/h3>\n<p>Warm-season grasses such as Bermuda, zoysia, St. Augustine, and centipede grow actively from late spring through summer. <strong>Late spring to early summer<\/strong> is the recommended aeration window for these varieties \u2014 after the grass has fully emerged from winter dormancy but before the intensity of midsummer heat sets in. Aerating too early while the grass is still dormant means the turf cannot recover effectively, and the open soil is left vulnerable.<\/p>\n<p><strong>Kansas State Research and Extension<\/strong> recommends consulting local cooperative extension resources for region-specific timing guidance, as climate conditions and local grass variety performance can shift the ideal aeration window by several weeks in either direction depending on where you live.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Lawn_Aeration_Is_Done\"><\/span>How Lawn Aeration Is Done<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The equipment and effort involved in aeration depend on the size of your lawn and the severity of compaction you need to address. Most homeowners find that renting equipment makes core aeration practical and cost-effective without requiring a large equipment investment.<\/p>\n<h3>Choosing the Right Equipment<\/h3>\n<p>For most residential lawns, a <strong>walk-behind core aerator<\/strong> is the appropriate tool. These machines resemble a large, heavy lawn mower and are widely available at home improvement stores and equipment rental shops, typically rented for a half-day or full-day fee. Tow-behind core aerator attachments suit larger properties or those with a riding mower. For small areas or targeted spot treatments, manual core aerators \u2014 a stepped frame with hollow tines you press into the soil with your foot \u2014 are available, though they require considerably more physical effort per square foot covered.<\/p>\n<h3>The Aeration Process Step by Step<\/h3>\n<ol>\n<li><strong>Water the lawn one to two days beforehand<\/strong> \u2014 moist soil allows the tines to penetrate more easily and produces cleaner, deeper cores. Avoid aerating immediately after heavy rain, as saturated soil can compact further under machine weight during the pass.<\/li>\n<li><strong>Mark any hidden features<\/strong> \u2014 flag irrigation heads, shallow utility lines, or in-ground sprinkler system components to prevent damage during operation.<\/li>\n<li><strong>Make at least two passes in perpendicular directions<\/strong> \u2014 running the aerator across the lawn in two directions ensures adequate coverage and distributes holes more evenly across the turf surface for consistent results.<\/li>\n<li><strong>Leave the soil plugs on the surface<\/strong> \u2014 resist the urge to rake them up immediately. They will break down naturally within one to two weeks, returning nutrients and beneficial microbes directly back to the lawn.<\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"What_to_Do_After_Aerating\"><\/span>What to Do After Aerating<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Aeration opens a valuable window of opportunity for broader lawn improvement. What you do in the days immediately following aeration can significantly multiply the long-term benefits of the process and determine how much your lawn visibly improves by the following season.<\/p>\n<h3>Overseed for Thicker, Denser Turf<\/h3>\n<p>Immediately after aeration is the best possible time to overseed, because grass seeds fall directly into the open cores and achieve excellent contact with moist soil beneath. Broadcast seed evenly over the entire lawn using a spreader, concentrating extra seed on thin or bare patches. Germination rates from overseeding combined with fresh core aeration are substantially higher than overseeding onto an unaerated surface.<\/p>\n<h3>Topdress with Compost<\/h3>\n<p>A light application of screened compost or topsoil brushed across the lawn surface after aeration helps fill the cores and introduces organic matter directly into the soil profile. <strong>Ohio State University Extension<\/strong> highlights compost topdressing as a particularly effective complement to core aeration for improving long-term soil health, moisture retention, and microbial activity across the root zone.<\/p>\n<h3>Fertilize and Water Consistently<\/h3>\n<p>Apply a balanced fertilizer after aeration to take advantage of the improved nutrient access pathways that the open cores provide. Keep the lawn consistently moist \u2014 particularly if you have overseeded \u2014 until new grass seedlings are well established. Avoid heavy foot traffic on the aerated area during the recovery period, which typically lasts two to four weeks depending on the grass type and growing conditions.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Common_Aeration_Mistakes_to_Avoid\"><\/span>Common Aeration Mistakes to Avoid<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Even a genuinely beneficial maintenance practice can produce poor results \u2014 or cause harm \u2014 when applied incorrectly. Here are the most important mistakes to sidestep when planning and executing your lawn aeration.<\/p>\n<ul>\n<li><strong>Aerating soil that is too wet or too dry<\/strong> \u2014 extremely wet soil compacts further under machinery weight during the pass, while bone-dry, rock-hard soil resists tine penetration and produces incomplete or crumbling cores that deliver little benefit.<\/li>\n<li><strong>Relying solely on spike aeration<\/strong> \u2014 spike tools do not remove soil material and can actually worsen compaction around hole walls over time. Always use hollow-tine core aeration for meaningful, lasting improvement to the soil structure.<\/li>\n<li><strong>Aerating at the wrong time of year<\/strong> \u2014 aerating during full dormancy or at the peak of summer heat stress prevents effective turf recovery and wastes the effort along with any seed or fertilizer applied in the follow-up window.<\/li>\n<li><strong>Skipping aftercare entirely<\/strong> \u2014 aeration alone produces limited results if overseeding, topdressing, and consistent watering are not carried out promptly in the days when the soil is most open and receptive to improvement.<\/li>\n<li><strong>Aerating too infrequently on problem soils<\/strong> \u2014 clay-heavy soils, high-traffic lawns, and yards with visible compaction often benefit from aeration once or twice per year, not once every several years as some homeowners assume based on general advice.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Lawn aeration is one of the most effective and underutilized tools in residential lawn care. By physically removing small soil cores, aeration relieves compaction, helps break down accumulated thatch, opens direct pathways for water and nutrients, and creates the conditions for deep, resilient root growth. The results \u2014 a denser, greener, more stress-tolerant lawn \u2014 are often visible within a single growing season when aeration is paired with proper overseeding, targeted fertilizing, and consistent watering in the days that follow.<\/p>\n<p>The practice is not complicated, but timing and technique matter enormously. Whether you rent a core aerator for a Saturday morning project or bring in a lawn care professional to handle it on your behalf, understanding why aeration works and when to use it puts you well ahead of most homeowners. For lawn problems that have not responded to fertilizer adjustments or improved irrigation, compacted soil is frequently the hidden culprit \u2014 and core aeration remains the most direct, proven solution available to fix it at the root level.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"References\"><\/span>References<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><a href=\"https:\/\/hgic.clemson.edu\/factsheet\/aerating-lawns\/\" rel=\"nofollow noopener\" target=\"_blank\">Clemson Cooperative Extension Home &amp; Garden Information Center &#8211; Aerating Lawns<\/a> &#8211; Dedicated extension fact sheet explaining soil compaction, core aeration benefits, timing by grass type, frequency, and practical aeration methods.<\/li>\n<li><a href=\"https:\/\/bookstore.ksre.ksu.edu\/pubs\/MF2130.pdf\" rel=\"nofollow noopener\" target=\"_blank\">Kansas State Research and Extension &#8211; Aerating Your Lawn<\/a> &#8211; University extension PDF focused on lawn aeration basics, timing, and practical recommendations for effective core aeration.<\/li>\n<li><a href=\"https:\/\/ohioline.osu.edu\/factsheet\/hyg-4031\" rel=\"nofollow noopener\" target=\"_blank\">Ohio State University Extension &#8211; Natural Organic Lawn Care<\/a> &#8211; Includes a clear core aeration and thatch management section explaining why removing soil cores is more effective than simply punching holes.<\/li>\n<li><a href=\"https:\/\/content.ces.ncsu.edu\/carolina-lawns\" rel=\"nofollow noopener\" target=\"_blank\">NC State Extension &#8211; Carolina Lawns<\/a> &#8211; Comprehensive university lawn-care guide with references to coring, soil compaction, thatch, lawn renovation, and seed-to-soil contact.<\/li>\n<li><a href=\"https:\/\/extension.missouri.edu\/publications\/g6708\" rel=\"nofollow noopener\" target=\"_blank\">University of Missouri Extension &#8211; Managing Thatch in Home Lawns<\/a> &#8211; Useful supporting source for explaining thatch, why it harms lawns, and how core aerification helps improve air, water, fertilizer penetration, and soil microbe activity.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>A thick, green lawn doesn&#8217;t happen by accident.
