In moderate climates, that usually starts around mid-November.<\/p>    <p class=\"wp-block-paragraph\">Warm-season grasses handle heat well, but they can also stall out when summer temperatures rise above 90 degrees Fahrenheit.<\/p>    <figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Grass type<\/strong><\/td><td><strong>Stops growing below this temperature (Fahrenheit)<\/strong><\/td><td><strong>Stops growing above this temperature (Fahrenheit)<\/strong><\/td><\/tr><tr><td><a href=\"https:\/\/lawnlove.com\/blog\/bahiagrass-guide\/\">Bahiagrass<\/a><\/td><td>50\u00b0<\/td><td>86\u00b0<\/td><\/tr><tr><td>Bermudagrass<\/td><td>50\u00b0<\/td><td>100\u00b0<\/td><\/tr><tr><td><a href=\"https:\/\/lawnlove.com\/blog\/buffalograss-guide\/\">Buffalograss<\/a><\/td><td>50\u00b0<\/td><td>90\u00b0<\/td><\/tr><tr><td><a href=\"https:\/\/lawnlove.com\/blog\/carpetgrass-guide\/\">Carpetgrass<\/a><\/td><td>60\u00b0<\/td><td>90\u00b0<\/td><\/tr><tr><td><a href=\"https:\/\/lawnlove.com\/blog\/centipedegrass-guide\/\">Centipedegrass<\/a><\/td><td>55\u00b0<\/td><td>95\u00b0<\/td><\/tr><tr><td>St. Augustinegrass<\/td><td>55\u00b0<\/td><td>95\u00b0<\/td><\/tr><tr><td><a href=\"https:\/\/lawnlove.com\/blog\/zoysiagrass-guide\/\">Zoysiagrass<\/a><\/td><td>50\u00b0<\/td><td>95\u00b0<\/td><\/tr><\/tbody><\/table><\/figure>    <h2 id=\"10-how-do-i-take-care-of-dormant-grass-so-it-doesnt-die-\" class=\"wp-block-heading\"><span id=\"how-do-i-take-care-of-dormant-grass-so-it-doesnt-die\"><span id=\"how-do-i-take-care-of-dormant-grass\">How do I take care of dormant grass so it doesn&#8217;t die?<\/span><\/span><\/h2>    <p class=\"wp-block-paragraph\">Caring for dormant grass means doing less: stop <a href=\"https:\/\/lawnlove.com\/lawn-mowing\">mowing<\/a>, cut back watering, skip fertilizer, hold off on aeration, and keep foot traffic low. Ease off the stress and let the lawn green back up on its own once the weather turns.<\/p>    <ul class=\"wp-block-list\"> <li><strong>Stop mowing.<\/strong> Cutting grass that isn&#8217;t growing only stresses it out. Give it, and yourself, a break.<\/li>    <li><strong>Scale back on watering.<\/strong> Dormant grass still needs some moisture, just far less than when it&#8217;s growing. If the ground isn&#8217;t frozen, water enough to keep the top inch or two of soil moist.<\/li>    <li><strong>Skip fertilizer outside the growing season.<\/strong> The grass either won&#8217;t use it or will push tender new growth that&#8217;s too vulnerable to heat, cold, and drought.<\/li>    <li><strong>Wait to <a href=\"https:\/\/lawnlove.com\/blog\/how-to-aerate-lawn\/\">aerate<\/a>.<\/strong> Aeration is invasive, so the <a href=\"https:\/\/lawnlove.com\/blog\/when-to-aerate-lawn\/\">best time to aerate<\/a> is when grass is actively growing and can recover fast.

Common culprits behind dead turf include excessive thatch that blocks water and nutrients, drought stress, compacted soil, poor mowing practices, improper watering, summer pests like grubs, and lawn diseases.<\/p>    <figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><thead><tr><th>Repair method<\/th><th>Typical cost<\/th><th>Speed to fill in<\/th><\/tr><\/thead><tbody><tr><td>Grass seeding cost<\/td><td>$0.07 to $0.23 per sq. ft.<\/td><td>Slower<\/td><\/tr><tr><td>Sod installation cost<\/td><td>$1.70 to $2.60 per sq. ft.<\/td><td>Instant grass<\/td><\/tr><\/tbody><\/table><\/figure>    <h2 id=\"12-faqs\" class=\"wp-block-heading\"><span id=\"faqs\">FAQs<\/span><\/h2>    <div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-0\"><strong class=\"schema-faq-question\">What temperature actually kills grass?<\/strong> <p class=\"schema-faq-answer\">It depends on tissue temperature, not air temperature, so well-insulated grass can survive extremes. According to Turfax, the <a href=\"https:\/\/turf.unl.edu\/news\/high-temps-are-hard-cool-season-grasses\/\" target=\"_blank\" rel=\"noreferrer noopener\">lethal threshold<\/a> is roughly 110 to 120 degrees Fahrenheit or below 20 to 31 degrees for warm-season grasses, and 104 to 112 degrees or as low as -20 degrees for cool-season grasses.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1\"><strong class=\"schema-faq-question\">How long can grass stay dormant before dying?<\/strong> <p class=\"schema-faq-answer\">Most lawns tolerate about 3 to 4 weeks of <a href=\"https:\/\/www.auroragov.org\/residents\/water\/drought\/grass_dormancy\" target=\"_blank\" rel=\"noreferrer noopener\">drought dormancy<\/a> without harm, and cold dormancy lasts an entire season. Beyond roughly a month of severe drought, give the lawn a <a href=\"https:\/\/extension.illinois.edu\/lawns\/managing-lawns-during-drought\" target=\"_blank\" rel=\"noreferrer noopener\">half-inch of water<\/a> every 2 to 3 weeks to keep the crowns alive.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-2\"><strong class=\"schema-faq-question\">Can I overseed a dormant lawn to speed up green-up in spring?<\/strong> <p class=\"schema-faq-answer\">Dormant seeding works best in late fall for cool-season grasses, where seed sits in the soil and sprouts once temperatures rise, but it won&#8217;t make already-dormant blades green up any faster. For warm-season lawns, wait until soil warms in spring since dormant-seeded warm-season grass usually rots before germinating.<\/p> <\/div> <\/div>    <h2 id=\"13-hire-a-local-lawn-care-pro-\" class=\"wp-block-heading\"><span id=\"hire-a-local-lawn-care-pro\"><span id=\"need-help-with-your-lawn\">Hire a local lawn care pro<\/span><\/span><\/h2>    <p class=\"wp-block-paragraph\">Not sure whether your lawn is napping or gone for good?
