Don’t start performing funeral rights on your brown grass. It most likely is not dead, just dormant.
It’s normal for the grasses that are traditionally grown in Utah to struggle with the heat and drought we are experiencing now, says Kelly Kopp, Utah State University Extension water conservation and turf grass specialist. You may be seeing brown or golden patches forming in your lawn right now. Fortunately, these grasses have the capability to recover from these extreme weather conditions. Usually when the grass appears to be dead at this time of year, it is only dormant.
Dormancy is the physiological process that grasses use to protect themselves from heat and drought, Kopp says. This state is characterized by a complete cessation of growth along with brown or dead grass blades. The grass blades are not as much of a concern, however, as the crown of the grass plant.
By entering dormancy, grasses are really protecting their crowns for future recovery, she says. The crown is at the soil surface and it is the point from which the grass blades grow up and the roots grow down. As long as the crown remains alive, the grass has the capability to recover once temperature and moisture conditions improve.
Recognize that when heat and drought reach a certain level, there is no amount of water that is going to coax the grass out of dormancy, Kopp explains. However, as temperatures drop and moisture increases, the grass will recover naturally.
Completely giving up on grass irrigation is not recommended, she says. You may, however, cut back to a minimal amount that will help keep the crowns of the grass plants alive. This amount of irrigation is known as “survival watering” because while it will not keep the grass from entering dormancy, it will help the grass crowns survive and recover. For the coolseason grasses that are traditionally grown in Utah, this irrigation amount can be as little as one inch of water per month.
Dormancy is a protective process that grass plants use to survive harsh climatic conditions, Kopp says. It is not to be feared or avoided at all costs. Instead, be patient and recognize that the grass will recover in the fall.

Are you concerned about a bumpy, rough area in your lawn? Does a close inspection of your lawn reveal a miniature replica of the Wasatch Mountain Range? Such areas can be annoying, hard to mow, and even dangerous for anyone walking or running across them.
After a long, hot summer, your lawn can look pretty sad. The heat and drought conditions take a toll, because most of our turf grasses are adapted to cool weather. During the heat of the summer, they stop growing and often go dormant. If conditions become
Much like human beings, plants also have different ways of dealing with the heat, said Jerry Goodspeed, Utah State University Extension horticulturist.
Thatch is living and dead turfgrass stems, stolons, and rhizomes that occur just above the soil level. How can you manage it?
As a homeowner, you likely don’t think much about the grass in your lawn. You mow it, water it, and expect it to always be there But grass, like all living things, has a finite lifespan So how long does lawn grass actually live? The answer depends on several factors.
Annual vs. Perennial Grasses
There are two main categories of grass – annual and perennial.
Annual grasses, such as annual ryegrass, go through their entire lifecycle in one year. They germinate, grow, produce seeds, and die within a single growing season. Annuals produce many seeds to ensure new plants for the next year.
Perennial grasses live for multiple years. Cool season perennial grasses like fescue, Kentucky bluegrass, and ryegrass live for around 4-7 years on average with proper care. Warm season perennials like Bermuda grass and zoysia may live even longer – 10 years or more.
Perennials continue living year after year, producing new shoots and spreading via above ground stolons, below ground rhizomes, and sometimes seeds.
Factors That Determine Lifespan
Several key factors impact how long grass will live:
Growth Habit
Spreading grasses that propagate through stolons and rhizomes tend to have greater longevity. As existing plants die off, new shoots quickly fill the gaps. This maintains a lush, uniform lawn.
Clumping grasses like tall fescue grow in bunches. When one plant dies, it leaves an obvious bare spot. These require more reseeding to maintain thickness.
Water
Adequate moisture is critical for healthy grass. During drought dormancy, cool season grasses may survive 6+ weeks without water. Warm season grasses are even more drought tolerant. Too much water can also be detrimental, causing root rot. Proper irrigation optimizes lifespan.
Soil Fertility
Grasses need nitrogen, phosphorus, and potassium to thrive. Insufficient nutrients lead to stunted growth and earlier death. A soil test indicates which nutrients the lawn needs. Regular fertilization encourages deep roots and longevity.
Sunlight
Grasses grow best with at least 6 hours of direct sun daily. Too much shade causes thinning and die off. Selecting shade tolerant varieties or pruning trees can help sun-starved grass.
Traffic
Heavy foot traffic and activity accelerates wear and tear. Grass like Bermuda and hybrid Bermuda withstands frequent use well. More delicate grasses like fescue require rest and recovery periods.
Can Lawn Grass Live Forever?
Individual grass plants live around 3-5 years typically. However, a healthy lawn can theoretically continue indefinitely through proper maintenance. As existing plants expire, new ones fill the void via spreading or reseeding.
Natural prairies and pastures have flourished for centuries with no human intervention. Similarly, a well cared for home lawn can survive for decades. There are St. Augustine lawns in the southern U.S. still going strong after 60-80 years!
When to Start Fresh
Replacing an entire existing lawn should be rare. It is only necessary if you wish to change grass species or have severe issues like:
- Poor drainage
- Compacted soil
- Heavy thatch buildup
- Persistent disease/pests
- Large bare areas
Starting fresh gives you a blank slate to correct these underlying problems before replanting.
The Secret to Grass Longevity
The key to maximizing lawn grass lifespan is proper maintenance. Here are some best practices:
-
Mow at the ideal height for your grass type. Never remove more than 1/3 of blade height when cutting.
-
Water deeply and infrequently. 1-1.5 inches per week is typical.
-
Fertilize based on soil tests, using organic or synthetic fertilizers.
-
Dethatch and aerate to alleviate soil compaction.
-
Overseed to fill bare spots.
-
Control weeds which compete for space and nutrients.
-
Prevent and treat diseases.
With the right care, you can keep your lawn thick and lush for decades to come. Let your grass live long and prosper!
-
Annual grasses live one year while perennial grasses survive 4-10+ years typically.
-
Growth habit, water, sunlight, soil, and traffic impact lifespan.
-
Proper maintenance and care can extend the life of a lawn indefinitely.
-
Replacing an entire lawn should only be done to correct severe underlying issues.
-
Consistent best practices like mowing, fertilizing, aerating, and seeding are key for grass longevity.

FAQ
What is the lifespan of a grass?
When should you replace your lawn?
– Extensive Bare Spots or Thinning Grass: If your lawn has more dirt than grass and new growth struggles to take root, it’s likely a sign that the underlying issues are too far gone for simple patchwork solutions.
At what point does grass stop growing?
When Does Grass Stop Growing? If the weather is warm enough, grass keeps sprouting. Generally, the cutoff point comes when temperatures drop below 50°F during the day. Usually, that’s late October or early November, but some warm areas may push that date back to the beginning of December.Sep 28, 2022
Does watering your grass help it grow?
Yes, watering your grass is essential for healthy growth. Grass needs water to survive and thrive, but the key is to water deeply and less frequently, rather than shallow and often.
