You may need a few sporadic irrigation sessions in April, but wait until May or June to begin your routine watering schedule. <\/p>    <p class=\"wp-block-paragraph\">Allowing your lawn to stay dormant a couple extra weeks doesn\u2019t affect the quality of the grass; it simply saves water. In fact, keeping your lawn a little thirsty forces the roots to dig deep in search of moisture, which ultimately strengthens the grass.<\/p>    <p class=\"wp-block-paragraph\">Once fall rolls around and the temperature is down to the 30s at night, stop watering. When the ground gets too cold, it doesn\u2019t absorb the water well, and standing water could turn to ice, which will severely damage your grass.<\/p>    <p class=\"wp-block-paragraph\">You can plan to winterize your irrigation system in October, but similar to the springtime, you may need to hand water once or twice after that, but not regularly.&nbsp;<\/p>    <h2 class=\"wp-block-heading\" id=\"2-best-time-of-day-to-water-your-lawn-in-boulder\">Best Time of Day to Water Your Lawn in Boulder<\/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\/05\/Man-watering-lawn-with-hose.jpg\" alt=\"Man watering green lawn with a hose\" class=\"wp-image-114326\" srcset=\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/05\/Man-watering-lawn-with-hose.jpg 800w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/05\/Man-watering-lawn-with-hose-300x200.jpg 300w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/05\/Man-watering-lawn-with-hose-150x100.jpg 150w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/05\/Man-watering-lawn-with-hose-768x513.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Photo Credit: <a href=\"https:\/\/stock.adobe.com\/images\/man-watering-green-lawn-sprinkling-water-on-the-grass-with-water-pistol-close-up-with-no-face\/290201676?prev_url=detail&amp;asset_id=290201676\" target=\"_blank\" rel=\"noreferrer noopener\">rh2010<\/a> \/ Adobe Stock Free \/ <a href=\"https:\/\/stock.adobe.com\/license-terms\" target=\"_blank\" rel=\"noreferrer noopener\">License<\/a><\/figcaption><\/figure>    <p class=\"wp-block-paragraph\">We recommend watering your Boulder lawn at night or in the wee hours of the morning. This allows the water to absorb deep into the roots before the hot Colorado sun evaporates it. Evaporation is not only a waste of precious water, but it robs your grass of the water it should be getting.<\/p>    <p class=\"wp-block-paragraph\">You can set your sprinklers to turn on anytime between 10 p.m. and 6 a.m., ensuring the cycle is done before sunrise.&nbsp;<\/p>    <p class=\"wp-block-paragraph\">We also recommend deep, yet infrequent watering sessions. For example, instead of watering for 5 minutes every night, opt for 15 minutes twice a week. Furthermore, the City of Boulder suggests <a href=\"https:\/\/bouldercolorado.gov\/services\/water-conservation\" target=\"_blank\" rel=\"noreferrer noopener\">cycling your sprinkler system<\/a>. Instead of watering for 15 minutes straight, water for 5 minutes, then wait an hour and repeat for a total of three cycles. This is another way to ensure the water soaks deep into the roots and reduces any runoff. <\/p>    <p class=\"wp-block-paragraph\">Always check with and follow the current city or county guidelines.&nbsp;<\/p>    <h2 class=\"wp-block-heading\" id=\"3-look-for-signs-of-dehydration\">Look for Signs of Dehydration<\/h2>    <figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"800\" height=\"533\" src=\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/Lawn-in-bad-condition.jpg\" alt=\"Grass texture. grass background. patchy grass, lawn in bad condition and need maintaining, Pests and disease cause amount of damage to green lawns, lawn in bad condition\" class=\"wp-image-115040\" srcset=\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/Lawn-in-bad-condition.jpg 800w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/Lawn-in-bad-condition-300x200.jpg 300w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/Lawn-in-bad-condition-646x430.jpg 646w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/Lawn-in-bad-condition-150x100.jpg 150w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/Lawn-in-bad-condition-768x512.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Photo Credit: <a href=\"https:\/\/stock.adobe.com\/images\/grass-texture-grass-background-patchy-grass-lawn-in-bad-condition-and-need-maintaining-pests-and-disease-cause-amount-of-damage-to-green-lawns-lawn-in-bad-condition-and-need-maintaining\/373607185?prev_url=detail&amp;asset_id=373607185\" target=\"_blank\" rel=\"noreferrer noopener\">singjai<\/a> \/ Adobe Stock Free \/ <a href=\"https:\/\/stock.adobe.com\/license-terms\" target=\"_blank\" rel=\"noreferrer noopener\">License<\/a><\/figcaption><\/figure>    <p class=\"wp-block-paragraph\">Water your lawn only if it needs to be watered.

You can determine your sprinkler system\u2019s output by placing shallow dishes or tuna cans around your lawn while the sprinklers are running. After 30 minutes, measure how much water you\u2019ve collected \u2013\u2013 it should be about a half-inch. Now, you can adjust your watering schedule to ensure your grass gets the proper amount of water each week.<\/p>    <p class=\"wp-block-paragraph\"><strong>Grass Type<\/strong><\/p>    <p class=\"wp-block-paragraph\">Not all grasses thrive in Colorado. The <a href=\"https:\/\/www.lawnstarter.com\/blog\/colorado\/boulder-co\/best-grass-boulder\/\">best grasses for Boulder<\/a> are generally cool-season varieties, which need more water in the hot summer months than warm-season grasses do.\u00a0<\/p>    <p class=\"wp-block-paragraph\"><strong>Sun Exposure<\/strong><\/p>    <p class=\"wp-block-paragraph\">A lawn that gets a lot of sun will need more water than one that\u2019s mostly shaded because the hot sun will dry out the soil.&nbsp;<\/p>    <p class=\"wp-block-paragraph\"><strong>Elevation<\/strong><\/p>    <p class=\"wp-block-paragraph\">If your lawn is not flat, but has areas with higher elevation, the higher areas may need more water because any excess water will flow to the lower areas and not absorb into the hills.<\/p>    <p class=\"wp-block-paragraph\"><strong>Grass Height<\/strong><\/p>    <p class=\"wp-block-paragraph\">The taller the grass, the deeper the roots, and the deeper the roots, the better water absorption it has. Therefore, taller grass needs less water than shorter grass.&nbsp;<\/p>    <p class=\"wp-block-paragraph\"><strong>Soil Type<\/strong><\/p>    <p class=\"wp-block-paragraph\">Sandy soils quickly soak up water while clay does not. If your lawn has clay, water with very low pressure at a very slow pace. This gives the water sufficient time to soak in without puddling or running off.&nbsp;<\/p>    <h2 class=\"wp-block-heading\" id=\"5-water-wise-lawn-care-tips\">Water-Wise Lawn Care Tips<\/h2>    <figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"530\" src=\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2023\/04\/xeriscaping.jpg\" alt=\"Xeriscaping picture Outside the Nevada State Museum\" class=\"wp-image-88137\" srcset=\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2023\/04\/xeriscaping.jpg 800w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2023\/04\/xeriscaping-300x199.jpg 300w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2023\/04\/xeriscaping-646x428.jpg 646w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2023\/04\/xeriscaping-150x99.jpg 150w, https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2023\/04\/xeriscaping-768x509.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Photo Credit: <a href=\"https:\/\/www.flickr.com\/photos\/tomhilton\/14929011953\/in\/photolist-oKe68P-AbFEpy-2dWLGf-8zE8GZ-NZZdt3-TvWE5-TvFbJ-TvFcd-dRH9Wi-2gjRZ5n-TvFd7-2gjSqYx-2dWEfy-GUjZY6-TvQwm-TvFcu-2jqwS6Y-TvWFw-HgcSxc-TvWF1-TvWG7-TvFfd-4BA6MQ-E354uE-TvQwG-2kJ7NyZ-TvQyo-4BA6c3-8zE1Z8-TvQy5-TvWEE-6PSFTv-TvQAL-TvQxE-caQgK-2zytwo-6CrRic-eHvin-pXJBqf-q1WDh-caQnx-37Dw4x-g2FBG-2o6Ynwx-2kgdRVP-2gHz4J9-2hdaFMm-2hddeLM-2iHba3F-XyULEa\" target=\"_blank\" rel=\"noreferrer noopener\">Tom Hilton<\/a> \/ Flickr \/ <a href=\"https:\/\/creativecommons.org\/licenses\/by\/2.0\/\" target=\"_blank\" rel=\"noreferrer noopener\">CC BY 2.0<\/a><\/figcaption><\/figure>    <p class=\"wp-block-paragraph\">Here in the high desert, drought always seems to be a concern.
