Wyoming’s cooler night temperatures suit this popular turfgrass across the state. Kentucky bluegrass likes full sun, is very cold tolerant, and will hold up to kids and pets romping in the yard. If you live in eastern Wyoming, be aware that some Kentucky bluegrass cultivars need more fertilizer and water than others. 

Classification: Cool-season grass

Spreads by: Rhizomes

Shade tolerance: Low

Drought tolerance: Moderate

Foot traffic tolerance: Moderate

Maintenance needs: Moderate mowing frequency and high fertilization needs. 

Mowing height: Set mowing height between 2.5 and 3 inches.

Potential for disease: Moderate to high; prone to several diseases, such as dollar spot, leaf spot, necrotic ring spot, summer patch, and stripe smut. 

Soil pH: 6-7.5

Soil type: Performs best in well-drained, heavy soils with high fertility. 

Other notes: For a more water-thrifty Kentucky bluegrass, consider Park, North Dakota Common, and Kenblue varieties.

Fine fescue is a good drought-tolerant grass for eastern Wyoming. It’s also a good choice for a low-maintenance yard wherever you live. However, the fine fescues don’t stand up to foot traffic, so they aren’t a good choice if your lawn gets heavy use. 

Fine fescue lawns can be manicured (mowed regularly) or left to grow long and create a meadow-like lawn that is mowed one to two times per year. Manicured fine fescue lawns need from 0.5 to 1 inch of water each week, but meadow-like lawns need as little as 1 inch of water each month.

Classification: Cool-season grass

Spreads by: Creeping red fescue spreads by rhizomes, while other fine fescues are bunch-type grasses, such as Chewings, hard, and sheep fescues. 

Shade tolerance: Moderate to High, depending on species

Drought tolerance: Moderate to High, depending on species

Foot traffic tolerance: Low to Moderate, depending on species

Maintenance needs: Low fertilizer and mowing needs  

Mowing height: Set mowing height between 2.5 and 3 inches, depending on grass species. 

Potential for disease: Moderate. Common diseases include red thread, leaf spot, dollar spot, summer patch, and powdery mildew. 

Soil pH: 6-6.5

Soil type: Will not perform well in wet soil conditions. Prefers drier soils and tolerates a wide range of soil types and fertility. 

Other notes: Fine fescue grasses can grow in full sun in Wyoming. If you’re selecting turfgrass for a shaded lawn, consider creeping red, slender red, hard, Chewings, or sheep fescue.

Tall Fescue

This bunchgrass produces a mostly low-maintenance lawn that stands up to moderate foot traffic. Turf-type tall fescue’s strong, deep root system makes it heat and drought-tolerant, and thus a good choice for the semi-arid portions of the state. 

If you’re concerned about growing grass in the shade, tall fescue may be a good fit, as it will grow under partial shade conditions. However, if it thins out due to excessive shade or foot traffic, plan to get out the spreader to overseed each fall. Tall fescue is a bunch-type grass and won’t repair on its own.

Classification: Cool-season grass

Spreads by: Produces short rhizomes but has a bunch-type growth habit

Shade tolerance: Moderate

Drought tolerance: Moderate to High

Foot traffic tolerance: Moderate

Maintenance needs: Frequent mowing. Does not produce significant thatch. 

Mowing height: Set mowing height to 2.5 to 3 inches.

Potential for disease: Tolerant of most diseases when properly maintained. 

Soil pH: 5.5-6.5

Soil type: Adapted to a wide range of soil conditions, but prefers fertile clay soils with good drainage. 

Other notes: Don’t mix tall fescues with other turfgrasses. If you’re putting in a new lawn, you can buy seed mixtures of several different tall fescue cultivars.

This bunchgrass is usually found in a seed mix with Kentucky bluegrass. It germinates and greens up quickly to give your lawn a head start. It’s also used on sloping areas to prevent erosion. Ryegrass stands up to foot traffic but doesn’t care for shady areas. It also doesn’t do well with the cold, especially in windy conditions.

Classification: Cool-season grass

Spreads by: Has a bunch-type growth habit

Shade tolerance: Low

Drought tolerance: Low

Foot traffic tolerance: High

Maintenance needs: Moderate mowing and fertilization requirements. Thatch is not significant. 

Mowing height: Set mowing height to 1.5 to 2.5 inches

Potential for disease: High. Common diseases include gray leaf spot, red thread, and leaf spot/melting-out. 

Soil pH: Can grow in soils with a pH between 5 and 8, but prefers between 6 and 7. 

Soil type: Prefers good drainage and fertility, but can tolerate some poor drainage. 

Other notes: Generally, perennial ryegrass isn’t very drought tolerant. But University of Wyoming research has found that perennial ryegrass can do well in dryland as a low-maintenance grass

This warm-season grass, a native of the Great Plains, is a good choice for the state’s dryland areas as it needs little water and likes heat  — it’s happiest at lower elevations with hot temperatures. It also has a high cold tolerance and doesn’t need frequent mowing. However, it doesn’t tolerate shade or high foot traffic. 

Classification: Warm-season grass

Spreads by: Stolons

Shade tolerance: Low

Drought tolerance: High 

Foot traffic tolerance: Low 

Maintenance needs: Low fertilizer and mowing needs. Requires weed control. 

Mowing height: Set the mowing height at 2.5 to 2 inches.

Potential for disease: Good tolerance against diseases and insects

Soil pH: 6.5-7.5

Soil type: Native clay soils, not sandy soils

Other notes: Compared with other turf in Wyoming, buffalograss has a long dormancy period. It browns out at first frost and won’t green up until June, at the earliest.

Grass Seed Options:

Blue grama is another warm-season native grass of the Great Plains. It is slow-growing, but once established, it is very drought-resistant and heat tolerant, making it a good choice for dryland areas. It’s also cold-tolerant and doesn’t need to be mowed often. However, it doesn’t do well with heavy foot traffic or shade. 

Classification: Warm-season

Spreads by: Rhizomes

Shade Tolerance: Low

Drought Tolerance: High

Foot Traffic Tolerance: Low

Maintenance Needs: Low maintenance requirements

Mowing Height: Set mowing height at 2.5 to 3 inches.

Potential for Disease: Low to Moderate. Its most prevalent disease is fungal rust.   

Soil pH: 6.6-8.4

Soil Type: Tolerates a wide range of soil textures, including clays and sandy or gravelly loams. Does not perform well in wet, poorly drained soils. 

Other notes: For lawns, blue grama is usually mixed with buffalograss. Both have a long dormancy season and will go brown at first frost.

Choosing the Best Grass Type for Your Wyoming Lawn

So, what’s the best grass for the place you call home?  Where you live in Wyoming makes a difference, as does the way you use your lawn.  Ask yourself a few questions, then compare your answers to these lawn characteristics.

Best Grass Types for Western Wyoming

  • Kentucky bluegrass 
  • Fine fescues (Usually blended with Kentucky bluegrass, but a mix of the varieties can stand alone for a low-maintenance lawn.)
  • Perennial Ryegrass (Usually mixed with Kentucky bluegrass)

Best Grass Types for Eastern Wyoming

  • Kentucky bluegrass (Park, North Dakota Common, or Kenblue varieties.)
  • Fine fescues
  • Tall Fescues
  • Buffalograss
  • Blue grama

High-, Moderate-, or Low-Maintenance Grasses

Do you enjoy spending weekends and evenings on lawn-care chores?  Then consider a high- or moderate-maintenance grass. Prefer to do other things during the spring and summer? Go with low-maintenance grass. 

Moderate-maintenance grasses: Perennial ryegrass and Kentucky bluegrass, though bluegrass needs more fertilizing.  

Low-maintenance grasses: Fine fescues, blue grama, and buffalograss, though the latter needs more fertilizer. If you’re really mowing-adverse, be aware: Tall fescues need less fertilizer and water but more frequent mowing. 

Drought Tolerance

Wyoming, with its semi-arid areas, is the 5th driest state in the U.S. If you live in areas that are low on rainfall, plant grass seed from a variety that can thrive with less water. Check the U.S. Drought Monitor for current drought conditions in your area.

High drought tolerance:  Fine and tall fescues, depending on the cultivar; buffalograss, blue grama.

Moderate drought tolerance: Kentucky bluegrass (some cultivars are more water-thrifty than others) and fine and tall fescues, depending on the cultivar.

Low drought tolerance: Perennial ryegrass.

Traffic Tolerance

How much time do you spend on your lawn? Do you have family badminton or soccer games? Do you set up chairs to enjoy the evening in the backyard? Then consider  grass with high or moderate traffic tolerance.  Or are the kids grown, and you prefer to spend evenings on the deck? Go for grass with low traffic tolerance.

High traffic tolerance: Perennial ryegrass.

Moderate traffic tolerance: Kentucky bluegrass, tall fescue, and fine fescues, depending on the variety.

Low traffic tolerance: Fine fescues, depending on the variety; buffalograss, and blue grama.
