The answer is yes<\/strong>, and skipping this step is one of the biggest mistakes you can make.<\/p>    <p class=\"wp-block-paragraph\">If you don&#8217;t water after a fertilizer application, the fertilizer will sit on the grass blades and be of no help to your lawn. It needs to get into the soil to be of use. Additionally, you risk fertilizer burn if you don&#8217;t water after fertilizing. Granular fertilizer sitting on grass blades in the hot sun can scorch your lawn within hours.<\/p>    <p class=\"wp-block-paragraph\"><strong>What To Do Instead:<\/strong><\/p>    <ul class=\"wp-block-list\"> <li><strong>For granular fertilizer: <\/strong>Apply 1\/4 inch of water<strong> <\/strong>(15-20 minutes with most sprinklers) immediately after application. This washes fertilizer from grass blades into the soil, activating the product.<\/li>    <li><strong>For liquid fertilizer: <\/strong>Wait 2-4 hours before watering. This allows the product to absorb through grass blades. Always check your product label for specific timing<\/li> <\/ul>    <p class=\"wp-block-paragraph\"><strong>Important:<\/strong> Don&#8217;t overwater after fertilizing. Too much water washes nutrients away before grass roots can absorb them and can contaminate local groundwater. One light watering session is sufficient.<\/p>    <p class=\"wp-block-paragraph\"><strong>See Related:<\/strong> <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/liquid-vs-granular-fertilizer\/\">Liquid vs. Granular Fertilizer<\/a><\/p>    <h2 class=\"wp-block-heading\" id=\"1-mistake-2-applying-the-wrong-nutrients\">Mistake 2: Applying the Wrong Nutrients<\/h2>    <figure class=\"wp-block-image aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"534\" src=\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/04\/Fertilizer.jpg\" alt=\"Hand in glove holding nitrogen fertilizer\" class=\"wp-image-112445\" srcset=\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/04\/Fertilizer.jpg 800w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/04\/Fertilizer-300x200.jpg 300w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/04\/Fertilizer-646x431.jpg 646w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/04\/Fertilizer-150x100.jpg 150w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/04\/Fertilizer-768x513.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Fertilizer in hand.

Many people reach for all-in-one fertilizers because they&#8217;re convenient, but these products aren&#8217;t always the best fit for a lawn&#8217;s needs.<\/p>    <p class=\"wp-block-paragraph\">According to Hayden Bock, assistant professor of landscape sustainability at Penn State, \u201cHomeowners should recognize that big-box store all-in-one fertilizers are typically formulated to achieve a very high aesthetic, which research shows is significantly higher than most people\u2019s expectations.\u201d<\/p>    <p class=\"wp-block-paragraph\">In other words, these products are often designed to push lawns to look greener and denser than necessary, which can lead to excess growth, wasted fertilizer, and unnecessary nutrient runoff.<\/p>    <p class=\"wp-block-paragraph\"><strong>What To Do Instead:<\/strong><\/p>    <ol class=\"wp-block-list\"> <li><strong>Get a soil test<\/strong> from your local Extension office or a reputable lab before buying fertilizer.<\/li>    <li><strong>Review the results<\/strong> to see what nutrients your soil has and what it&#8217;s missing.<\/li>    <li><strong>Match your fertilizer to your needs<\/strong> using the <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/fertilizer-numbers-what-they-mean\/\">fertilizer number (NPK) ratio<\/a> on the bag.<\/li> <\/ol>    <p class=\"wp-block-paragraph\"><strong>See Related:<\/strong><\/p>    <p class=\"wp-block-paragraph\">\u2013 <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-choose-lawn-fertilizer\/\">How to Choose the Right Lawn Fertilizer<br><\/a>\u2013 <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-read-soil-test-report\/\">How to Read a Soil Test Report<\/a><\/p>    <h2 class=\"wp-block-heading\" id=\"2-mistake-3-over-fertilizing\">Mistake 3: Over-Fertilizing<\/h2>    <p class=\"wp-block-paragraph\"><strong>Can too much fertilizer kill grass?<\/strong> Absolutely. Too many nutrients at once can cause fertilizer burn, thinning turf, brown patches, or even dead sections of lawn. It also increases the risk of nutrient runoff.<\/p>    <p class=\"wp-block-paragraph\">As Bock explains, &#8220;Research conducted by my colleagues and I shows that more fertilizer doesn\u2019t automatically enhance aesthetics. Fertilizer promotes grass growth and improves aesthetics to a point, but doubling the amount doesn\u2019t make the grass twice as green.\u201d<\/p>    <p class=\"wp-block-paragraph\">\u201cThis means homeowners can often reduce fertilizer applications and still achieve an aesthetic that meets their expectations,\u201d he adds.<br><br><strong>What To Do Instead:<\/strong><\/p>    <ul class=\"wp-block-list\"> <li>Calculate your lawn&#8217;s square footage and follow label instructions.<\/li>    <li>Get a soil test to know exactly how much fertilizer your lawn needs.<\/li>    <li>Apply no more than 1 pound of nitrogen per 1,000 square feet per application.<\/li>    <li>Wait 6-8 weeks between applications.<\/li> <\/ul>    <p class=\"wp-block-paragraph\"><strong>See Related: <\/strong><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-fix-overfertilized-lawn\/\">How to Fix an Over-Fertilized Lawn<\/a><\/p>    <h2 class=\"wp-block-heading\" id=\"3-mistake-4-fertilizing-new-grass-too-soon\">Mistake 4: Fertilizing New Grass Too Soon<\/h2>    <figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"800\" height=\"443\" src=\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/AdobeStock_434623879-1-1.jpeg\" alt=\"Low-angle view of new grass shoots emerging from dark soil, backlit by bright morning sun with blurred garden background trees. \" class=\"wp-image-115510\" style=\"object-fit:cover\" srcset=\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/AdobeStock_434623879-1-1.jpeg 800w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/AdobeStock_434623879-1-1-300x166.jpeg 300w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/AdobeStock_434623879-1-1-150x83.jpeg 150w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/AdobeStock_434623879-1-1-768x425.jpeg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">New grass shoots in soil.

Fertilizing outside your grass growth season can do more harm than good.<\/p>    <p class=\"wp-block-paragraph\">If you apply too early, your grass will grow too quickly, resulting in a weaker root system and increased susceptibility to pests and disease. Conversely, if you fertilize too late, your lawn won&#8217;t have the vital nutrients it needs during the growing season, which will weaken it.<\/p>    <p class=\"wp-block-paragraph\"><strong>What To Do Instead:<\/strong><\/p>    <p class=\"wp-block-paragraph\">Follow the table below:<\/p>    <figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Grass Type<\/strong><\/td><td><strong>Primary Application<\/strong><\/td><td><strong>Secondary Application<\/strong><\/td><\/tr><tr><td><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/cool-season-grass-growing-guide\/\">Cool-season<\/a> (fescue, bluegrass, ryegrass)<\/td><td>Early fall (Sept.-Oct.)<\/td><td>Early spring (April-May)<\/td><\/tr><tr><td><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/warm-season-grass-growing-guide\/\">Warm-season<\/a> (Bermuda, St. Augustine, Zoysia)<\/td><td>Mid-spring\/early summer (April-June)<\/td><td>Late summer (July-August)<\/td><\/tr><\/tbody><\/table><\/figure>    <p class=\"wp-block-paragraph\"><strong>See Related:<\/strong> <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/when-to-fertilize-lawn\/\">When to Fertilize Your Lawn<\/a><\/p>    <h2 class=\"wp-block-heading\" id=\"5-mistake-6-not-fertilizing-often-enough-or-too-often\">Mistake 6: Not Fertilizing Often Enough (Or Too Often)<\/h2>    <p class=\"wp-block-paragraph\"><strong>How often should you fertilize your lawn?<\/strong> That depends on your grass type and climate.

For Bock, \u201cIt is useful for homeowners to grab a shovel, get their hands dirty, and take a look at the soil in their lawn every so often to build an intuition about what &#8216;soil health&#8217; actually is.\u201d<\/p>    <p class=\"wp-block-paragraph\">Healthy soil should show signs of life, feel moist and crumbly rather than compacted, and allow grass roots to grow deeper than just the top few inches. Over time, Bock notes that repeated chemical inputs can subtly alter these conditions.<\/p>    <p class=\"wp-block-paragraph\">\u201cOne application of fertilizer isn\u2019t going to cause all these changes,\u201d Bock says, \u201cbut over time, the chemical inputs associated with intense lawn management (pesticides, herbicides, fertilizer) can degrade the physical, chemical, and biological properties of soil.\u201d<\/p>    <p class=\"wp-block-paragraph\">Checking your soil periodically gives you a baseline. If you notice increasing compaction, fewer organisms, or shallower roots, it may be time to reduce fertilizer inputs or rethink your approach.<\/p>    <h2 class=\"wp-block-heading\" id=\"9-faq\">FAQ<\/h2>    <div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1768577912178\"><strong class=\"schema-faq-question\">How Do I Fix Fertilizer Burn?<\/strong> <p class=\"schema-faq-answer\">To fix fertilizer burn, you need to remove the damaged grass as well as the leftover fertilizer.
