It is also less cold-hardy than other cool-season grasses and dislikes temperatures below 30 degrees for long periods.<\/p>    <p class=\"wp-block-paragraph\">There are 3 different ways to grow it, which sets it apart from many other grasses:<\/p>    <ul class=\"wp-block-list\"> <li><strong>As a permanent lawn<\/strong> in cooler northern climates and the <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/guide-to-growing-grass-in-the-transition-zone\/\" data-type=\"link\" data-id=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/guide-to-growing-grass-in-the-transition-zone\/\">transition zone<\/a>.

Unlike in the North, ryegrass is not expected to survive the summer: As heat returns, it dies out rather than going dormant, and the warm-season grass resumes growth. This is why Southern lawns need to be overseeded with new ryegrass every fall.<\/li>    <li><p><strong>As a temporary grass<\/strong>, thanks to quick germination.

That speed can be valuable, but it doesn\u2019t necessarily make perennial ryegrass the best long-term choice, especially in regions with hot, dry summers.<\/p>    <p class=\"wp-block-paragraph\">According to McKernan, faster germination may be beneficial \u201cif heavy rains are forecasted, if the site is large and has undergone significant construction, if it is a sports turf field that will be used soon, or if you are planting outside the normal planting window.\u201d<\/p>    <p class=\"wp-block-paragraph\">It may also make sense when establishing a new lawn after regrading. In these situations, getting grass growing quickly can help cover bare soil, reduce erosion, and make the area usable sooner.<\/p>    <p class=\"wp-block-paragraph\">However, homeowners should weigh those short-term benefits against perennial ryegrass\u2019s limited heat and drought tolerance. \u201c[For] most home lawns, these benefits don\u2019t outweigh the drawbacks of planting a ryegrass that will not be able to survive the heat and drought of Kansas summers,\u201d McKernan says.<\/p>    <p class=\"wp-block-paragraph\"><strong>The takeaway:<\/strong> Perennial ryegrass can be useful when rapid establishment is especially important, but it may not be a lasting solution in Kansas and other areas with similarly hot summers. In those climates, a more heat- and drought-tolerant grass, such as tall fescue, is generally a better choice for a permanent home lawn.<\/p>    <h2 id=\"7-how-do-you-establish-perennial-ryegrass\" class=\"wp-block-heading\">How Do You Establish Perennial Ryegrass?<\/h2>    <figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" src=\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2022\/09\/7185124265_3a41e44912_k-1.jpg\" alt=\"Perennial Ryegrass\"\/><figcaption class=\"wp-element-caption\">Perennial ryegrass.

It is rarely started from sod, and in many places sod is not even available. The reason is speed: seeds germinate in as little as 5 days, versus up to 30 days for Kentucky bluegrass. That fast start crowds out weeds and establishes the lawn quickly, so sod is rarely needed.<\/p>    <h3 id=\"8-the-cost-of-starting-perennial-ryegrass\" class=\"wp-block-heading\">The Cost of Starting Perennial Ryegrass<\/h3>    <p class=\"wp-block-paragraph\"><strong>Perennial ryegrass seed:<\/strong> Seed is the affordable, do-it-yourself route.

Time seeding to the cooler temps of spring and fall, when the grass grows most. The <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/best-time-plant-grass-seed\/\">best time to plant a new lawn<\/a> is early fall, followed by late spring, so the grass establishes before summer heat.<\/p>    <p class=\"wp-block-paragraph\">&#8220;<span style=\"color: #222222;\">The warmer the soil temperature, the faster the seeds will germinate, however, the more supplemental irrigation that is often required too,&#8221; McKernan says.<\/span><\/p>    <p class=\"wp-block-paragraph\">In northern areas, sow seed from mid-August to mid-September. In the transition zone, sow from mid-September through early or mid-October. <\/p>    <p class=\"wp-block-paragraph\">In the South, when growing ryegrass as a temporary winter cover, sow once soil temperatures cool in fall (typically mid-October to November), and at least a few weeks before the warm-season grass goes fully dormant.<\/p>    <h3 id=\"10-choosing-between-100-perennial-ryegrass-and-a-mixed-grass-lawn\" class=\"wp-block-heading\">Choosing Between 100% Perennial Ryegrass and a Mixed Grass Lawn<\/h3>    <p class=\"wp-block-paragraph\">Despite its strengths, perennial ryegrass is not grown as a monostand (single-grass lawn) as often as other cool-season grasses. It is usually mixed with other species and may not even be the primary grass in the seed mix.<\/p>    <p class=\"wp-block-paragraph\">Because it germinates quickly, perennial ryegrass can serve as a nurse grass, establishing early cover while slower-germinating grasses take hold. In a mixture with Kentucky bluegrass, for example, ryegrass helps provide quicker coverage and greater traffic tolerance, while Kentucky bluegrass offers better cold tolerance and can spread to repair thin or damaged areas.<\/p>    <p class=\"wp-block-paragraph\">You can still grow a 100% perennial ryegrass lawn, ideally where winters and summers are mild, such as Oregon, Washington, or the Carolinas. Because the grass does not spread through rhizomes or stolons, expect to reseed bare patches to maintain even coverage. Before buying seed for a monostand:<\/p>    <ol class=\"wp-block-list\"> <li><p><strong>Buy only improved turf-type varieties.<\/strong> Common or forage-type seed will not produce a high-quality lawn.<\/p><\/li>    <li><p><strong>Talk to a local Cooperative Extension specialist<em>.<\/em><\/strong> Ask whether a monostand suits your climate, since it is prone to winterkill in the cold and disease pressure in hot, humid weather.<\/p><\/li> <\/ol>    <h2 id=\"11-how-to-care-for-an-established-perennial-ryegrass-lawn\" class=\"wp-block-heading\">How to Care for an Established Perennial Ryegrass Lawn<\/h2>    <comment data-content=\" Removed this photo.

This grass has a short root system and is not very drought-tolerant, so it needs at least 1 inch of water a week from rain or irrigation. If it goes summer dormant, it recovers slowly and becomes more prone to insects, diseases, and weeds.<\/p>    <p class=\"wp-block-paragraph\">This applies to permanent ryegrass lawns in the North and transition zone, where the goal is to keep the grass alive through summer. It does not apply to Southern winter overseeding, which is expected to die out in late spring regardless of watering.<\/p>    <p class=\"wp-block-paragraph\">If you&#8217;re seeding ryegrass for the first time, you need to pay extra attention. &#8220;<span style=\"color: #222222;\">If a lawn has an irrigation system, or can be easily watered lightly a couple of times per day during germination, grass seed will germinate very quickly in late August. Once germinated, however, grass seed cannot be allowed to dry out, as this will kill the newly emerging plants,&#8221; McKernan says.<\/span><\/p>    <p class=\"wp-block-paragraph\"><strong>See Related: <\/strong><\/p>    <ul class=\"wp-block-list\"> <li><p><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-often-water-grass-summer\/\">How Often to Water Grass in Summer<\/a><\/p><\/li>    <li><p><a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-long-to-water-lawn-summer\/\">How Long to Water Your Lawn in Summer<\/a><\/p><\/li> <\/ul>    <h3 id=\"13-fertilize-to-keep-it-looking-nice\" class=\"wp-block-heading\">Fertilize to Keep It Looking Nice<\/h3>    <p class=\"wp-block-paragraph\">Fertilize with 4 pounds of nitrogen (N) per 1,000 square feet each year while the grass is actively growing.

Planting a mix of perennial ryegrass and disease-resistant turf-type tall fescue also helps.<\/p>    <h2 id=\"18-faqs\" class=\"wp-block-heading\">FAQs<\/h2>    <div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-17879406916054518\"><strong class=\"schema-faq-question\">Does Perennial Ryegrass Die in the Summer?<\/strong> <p class=\"schema-faq-answer\">It depends on the climate. In the North and transition zone, a stretch of heat around 87 degrees sends ryegrass into dormancy rather than killing it. In the South, though, spring and early summer heat kills ryegrass, which is why it has to be reseeded again each fall.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-17879406916051929\"><strong class=\"schema-faq-question\">What Is the Difference Between Perennial and Annual Ryegrass?<\/strong> <p class=\"schema-faq-answer\">Perennial ryegrass returns year after year when cared for, as long as temperatures are not too extreme. Annual ryegrass grows for a single season, or occasionally two as a biennial, if the winter is mild enough for it to keep growing.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-17879406916056338\"><strong class=\"schema-faq-question\">Do You Need to Reseed Perennial Ryegrass?<\/strong> <p class=\"schema-faq-answer\">Yes. Because it is a bunch-type grass that cannot fill in on its own, you will need to reseed when you see bare patches or thin spots. It is best to seed in early fall, at least 60 days before the first expected fall frost.<\/p> <\/div> <\/div>    <h2 id=\"19-get-help-with-your-lawn-care\" class=\"wp-block-heading\">Get Help With Your Lawn Care<\/h2>    <p class=\"wp-block-paragraph\">Perennial ryegrass is a great choice if you need a lawn that stands up to kids and pets.
