Fertilizer provides your lawn with the nutrients it needs to grow healthy.&nbsp;<\/p>    <p class=\"wp-block-paragraph\">A fertilizer consists of three nutrients: nitrogen, phosphorus, and potassium.&nbsp;<\/p>    <ul class=\"wp-block-list\"> <li><strong>Nitrogen <\/strong>helps your grass grow and gives it a dark green appearance.

After applying the fertilizer, water your turf again to ensure the nutrients reach the soil.&nbsp;<\/li>    <li><strong>Use a spreader: <\/strong>Drop and broadcast are two types of lawn spreaders. Drop spreaders distribute fertilizer exactly where you want it. Overlap each pass to cover the entire lawn. Broadcast spreaders distribute fertilizer widely in all directions.&nbsp;<\/li>    <li><strong>Fertilize at the right time: <\/strong>Early fertilization promotes rapid leaf growth without proper root development. Late fertilization is ineffective.&nbsp;<\/li>    <li><strong>Fertilize when it\u2019s dry: <\/strong>Fertilizing during rain will cause runoff, reducing the effectiveness of the fertilizer.&nbsp;<\/li>    <li><strong>Avoid fertilizing during drought: <\/strong>Fertilizing promotes new growth, but these leaves can&#8217;t withstand drought as mature grass blades.&nbsp;<\/li>    <li><strong>Use both organic and synthetic fertilizers: <\/strong>Organic fertilizers like grass clipping are more eco-friendly but can\u2019t provide your grass the nutrients it needs. We recommend combining organic and synthetic fertilizers for the best results.&nbsp;<\/li>    <li><strong>Choose between dry and liquid fertilizers: <\/strong>Dry fertilizers come in granular form and are usually slow-release. Liquid fertilizers are quick-release, so mix them with irrigation water before applying.&nbsp;<\/li> <\/ul>    <h3 class=\"wp-block-heading\" id=\"6-slow-release-vs-quick-release-fertilizers\">Slow-Release vs. Quick-Release Fertilizers<\/h3>    <p class=\"wp-block-paragraph\"><strong>Slow-release fertilizers<\/strong> are water-insoluble and release nutrients over an extended period of time. It simulates even grass growth, and you don\u2019t have to fertilize your lawn as often. They are more eco-friendly.&nbsp;<\/p>    <p class=\"wp-block-paragraph\"><strong>Quick-release fertilizers <\/strong>are water-soluble and release nutrients quickly into the soil. You can start seeing some grass immediately after using this fertilizer, but it can burn your grass if you don\u2019t apply it correctly. We recommend using <strong>quick-release fertilizers only on new lawns<\/strong>.&nbsp;<\/p>    <h2 class=\"wp-block-heading\" id=\"7-how-often-should-you-fertilize-\">How Often Should You Fertilize?&nbsp;<\/h2>    <p class=\"wp-block-paragraph\">Dumping all your fertilizer at once will cause <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/what-is-fertilizer-burn\/\">nitrogen burn<\/a> (grass turns yellow, brown, or tan after applying fertilizer).&nbsp;<\/p>    <p class=\"wp-block-paragraph\">The frequency of fertilizer applications depends on the <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-choose-lawn-fertilizer\/\">type of fertilizer<\/a> you use.

You can do that with a DIY kit available at any garden center or on Amazon, or you can send a sample to your local Extension Office. For more details, see our article: &#8220;<a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-use-soil-test-kit\/\">How to Use a Soil Test Kit on the Lawn<\/a>.&#8221;<\/li>    <li>Calculate your lawn area to know the amount of fertilizer needed. The general rule is to apply 1 pound of fertilizer per 1,000 square feet of lawn. <\/li>    <li>Water your grass two days before fertilizing, but don\u2019t overwater because the grass shouldn\u2019t be too wet or dry. Also, mow and remove debris from your lawn to make it easier for the soil to absorb fertilizer.<\/li>    <li>Use a lawn spreader to apply fertilizer evenly. A drop spreader distributes fertilizer exactly where you want it and is great for smaller yards.&nbsp;Broadcast spreaders distribute fertilizer widely in all directions, making them ideal for large yards. You can use a handheld spreader for tight spots.&nbsp;<\/li>    <li>After fertilizing, water your lawn to wash off any fertilizer from the grass blades into the soil.
