For cool-season grasses, the best time to fertilize is in the <strong>fall<\/strong>. For warm-season grasses, it\u2019s <strong>late<\/strong> <strong>spring through summer<\/strong>. <\/p>    <p class=\"wp-block-paragraph\">Fertilizing your lawn is not just about maintaining its lush appearance. It\u2019s also important for bolstering your grass against diseases and environmental stressors, such as drought conditions.&nbsp;<\/p>    <p class=\"wp-block-paragraph\">To ensure that you\u2019re not applying fertilizer blindly but nourishing your lawn with what it truly needs, consider conducting a <a href=\"https:\/\/lawnlove.com\/blog\/how-to-soil-test-your-lawn\/\">soil test<\/a> first. It will pinpoint any nutrient deficiencies and guide your schedule, giving information on whether your lawn would benefit more from a <strong>single annual treatment<\/strong> or needs <strong>more applications<\/strong> to look its best.<\/p>    <p class=\"wp-block-paragraph\">Let\u2019s dive into the specifics of this:<\/p>    <h3 class=\"wp-block-heading\" id=\"1-fertilizing-cool-season-grasses-in-colorado\"><span id=\"fertilizing-cool-season-grasses-in-colorado\">Fertilizing cool-season grasses in Colorado<\/span><\/h3>    <figure class=\"wp-block-image aligncenter size-full\"><img fetchpriority=\"high\" fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"450\" src=\"https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2019\/05\/cool-season-grass-1.jpg\" alt=\"growth of cool season grass\" class=\"wp-image-17693\" srcset=\"https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2019\/05\/cool-season-grass-1.jpg 800w, https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2019\/05\/cool-season-grass-1-300x169.jpg 300w, https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2019\/05\/cool-season-grass-1-768x432.jpg 768w, https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2019\/05\/cool-season-grass-1-610x343.jpg 610w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Infographic by Juan Rodriguez<\/figcaption><\/figure>    <p class=\"wp-block-paragraph\">Cool-season grasses like <a href=\"https:\/\/lawnlove.com\/blog\/kentucky-bluegrass-guide\/\">Kentucky bluegrass<\/a>, tall fescue, and perennial ryegrass are the most common grasses in Colorado. In fall, they\u2019re in their peak growth phase, which makes this season perfect for fertilizer application.<\/p>    <p class=\"wp-block-paragraph\">Here are a few tips regarding fertilizing in the fall:<\/p>    <ul class=\"wp-block-list\"> <li><strong>Single annual treatment:<\/strong> If a soil test indicates only one fertilizer application is needed annually, or if you choose to fertilize just once, schedule this in the fall.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li><strong>Timing by altitude:<\/strong> Fertilize from late September to early November if you live in lower altitudes. However, if you live in higher altitudes like Colorado Springs, apply fertilizer from mid-August to early September to ensure nutrients are absorbed before the ground freezes. Either way, make sure to fertilize two to three weeks before the ground begins to freeze.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li><strong>Spring fertilization: <\/strong>If you applied fertilizer in late fall, it might not be necessary to fertilize again in early spring. You can wait until late spring to early summer (May to mid-June).<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li><strong>Special considerations for sandy soils<\/strong>: Avoid fertilizing after late September if your soil is sandy, like along the Eastern Plains or in South Denver, as there is a risk of nutrients leaching into groundwater.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li><strong>Pro tip:<\/strong> Do not fertilize warm-season grasses during fall.<\/li> <\/ul>    <h3 class=\"wp-block-heading\" id=\"2-fertilizing-warm-season-grasses-in-colorado\"><span id=\"fertilizing-warm-season-grasses-in-colorado\">Fertilizing warm-season grasses in Colorado<\/span><\/h3>    <figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"800\" height=\"450\" src=\"https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2023\/09\/warm-season-grass.jpg\" alt=\"growth of warm season grass\" class=\"wp-image-17692\" srcset=\"https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2023\/09\/warm-season-grass.jpg 800w, https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2023\/09\/warm-season-grass-300x169.jpg 300w, https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2023\/09\/warm-season-grass-768x432.jpg 768w, https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2023\/09\/warm-season-grass-610x343.jpg 610w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Infographic by Juan Rodriguez<\/figcaption><\/figure>    <p class=\"wp-block-paragraph\">Native warm-season grasses like <a href=\"https:\/\/lawnlove.com\/blog\/buffalograss-guide\/\">buffalograss<\/a> and blue grama behave differently than their cool-season counterparts, with peak growth occurring during the warmer months.

Depending on your specific lawn needs and conditions, fertilization can range from <strong>one to four times a year.<\/strong><\/p>    <p class=\"wp-block-paragraph\">Here are some general guidelines based on grass type and recommendations from Colorado State University:<\/p>    <p class=\"wp-block-paragraph\"><strong>Cool-season grasses<\/strong><\/p>    <ul class=\"wp-block-list\"> <li><strong>First application: <\/strong>1\/2 to 1 pound of nitrogen per 1,000 square feet in <strong>early spring.<\/strong><\/li>    <li><strong>Second application:<\/strong> 1 pound of nitrogen per 1,000 square feet in<strong> late spring.<\/strong><\/li>    <li><strong>Third application:<\/strong> 1 pound of nitrogen per 1,000 square feet in <strong>early fall.<\/strong><\/li>    <li><strong>Fourth application (optional):<\/strong> 1 pound of nitrogen per 1,000 square feet in<strong> late fall.<\/strong><\/li> <\/ul>    <p class=\"wp-block-paragraph\">However, that doesn\u2019t mean you\u2019ll have to fertilize your lawn four times a year. A soil test will give a more accurate recommendation, but in general, fall applications are the most beneficial. In addition, if you fertilized in late fall, it might not be necessary to fertilize in early spring.<\/p>    <p class=\"wp-block-paragraph\"><strong>Warm-season grasses<\/strong><\/p>    <ul class=\"wp-block-list\"> <li><strong>First application:<\/strong> 1\/2 to 1 pound of nitrogen per 1,000 square feet in late spring.<\/li>    <li><strong>Second application: <\/strong>1\/2 to 1 pound of nitrogen per 1,000 square feet in July to August.<\/li> <\/ul>    <p class=\"wp-block-paragraph\">For all grass types, <a href=\"https:\/\/lawnlove.com\/blog\/bagging-vs-mulching-grass-clippings\/\">leaving grass clippings<\/a> after mowing can naturally reduce nitrogen needs by about 1\/4 to 1\/3, as they decompose and return nutrients to the soil.&nbsp;<\/p>    <h2 class=\"wp-block-heading\" id=\"5-how-to-choose-a-fertilizer-for-your-colorado-lawn\"><span id=\"how-to-choose-a-fertilizer-for-your-colorado-lawn\">How to choose a fertilizer for your Colorado lawn<\/span><\/h2>    <figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"534\" src=\"https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2024\/05\/Fertilizer.jpg\" alt=\"Hand in glove holding nitrogen fertilizer\" class=\"wp-image-23194\" srcset=\"https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2024\/05\/Fertilizer.jpg 800w, https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2024\/05\/Fertilizer-300x200.jpg 300w, https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2024\/05\/Fertilizer-768x513.jpg 768w, https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2024\/05\/Fertilizer-610x407.jpg 610w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\"><a href=\"https:\/\/stock.adobe.com\/images\/hand-in-glove-holding-nitrogen-fertilizer-concept-of-fertilizing-grass\/507995686\" target=\"_blank\" rel=\"noreferrer noopener\">Adobe Stock<\/a><\/figcaption><\/figure>    <p class=\"wp-block-paragraph\">Choosing the right fertilizer for your Colorado lawn involves understanding the various types available and selecting the one that best suits your lawn\u2019s specific needs. Here are some considerations when picking a fertilizer:<\/p>    <ul class=\"wp-block-list\"> <li><strong>Nutrient composition:<\/strong> Base your choice primarily on the results of a soil test. This will tell you exactly which nutrients your lawn is lacking and which it has in abundance. Most Colorado lawns, for instance, usually need more nitrogen and less (or no) phosphorus and potassium.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li><strong>Convenience: <\/strong>Decide whether you prefer the ease of applying <a href=\"https:\/\/lawnlove.com\/blog\/liquid-vs-granular-fertilizers\/\">liquid fertilizers<\/a> or if you\u2019re fine with using granular types, which are usually more cost-effective and have longer-lasting effects. Some products also include weed control (the so-called \u201cweed and feed\u201d), which might be beneficial if you\u2019re dealing with an infestation.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li><strong>Price: <\/strong>Fertilizers come in a wide range of prices, and the best choice often balances cost with effectiveness. Consider how much you\u2019re willing to spend.<\/li> <\/ul>    <p class=\"wp-block-paragraph\"><strong>Pro tip:<\/strong> <a href=\"https:\/\/extension.colostate.edu\/docs\/pubs\/garden\/xcm222.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Colorado State University<\/a> recommends using slow-release fertilizers.

Options such as sulfur-coated or natural, organic fertilizers can reduce the risk of leaching.<\/p>    <p class=\"wp-block-paragraph\">If you\u2019d rather leave this decision to a professional, consider hiring a <a href=\"https:\/\/lawnlove.com\/colorado\/denver-lawn-care\">Denver lawn care pro<\/a>.<\/p>    <h3 class=\"wp-block-heading\" id=\"10-when-do-i-fertilize-my-lawn-in-colorado-springs\"><span id=\"when-do-i-fertilize-my-lawn-in-colorado-springs\">When do I fertilize my lawn in Colorado Springs?<\/span><\/h3>    <p class=\"wp-block-paragraph\">Due to its high altitude (over 6,000 feet), Colorado Springs lawns experience an early onset of winter compared to lower-altitude regions. As such, aim to apply fertilizer from mid-August to early September as soon as the weather begins to cool.<\/p>    <p class=\"wp-block-paragraph\">You can also apply fertilizer in the spring, as the snow melts and the soil begins to warm up, to help kickstart your lawn\u2019s growth after winter.
