Best Grass for a Twin Cities Lawn, and When to Plant It

Quick answer

Most sunny Twin Cities lawns do well with Kentucky bluegrass, often blended with perennial ryegrass. Fine fescues are the best choice for shade and low-input lawns, and turf-type tall fescue suits lower-maintenance sunny areas. University of Minnesota Extension says the best time to seed is mid-August to mid-September; sod can go down any time in the growing season if it can be watered.

Every lawn in Minneapolis, St. Paul and the surrounding suburbs is a cool-season lawn. The grasses that do well here grow most in spring and fall, slow down in midsummer heat, and survive months under snow. Within that group there are real choices, and picking the right grass for your sun, use and patience makes more difference than any fertilizer program. This guide walks through the options, the timing and the Minnesota rules that affect a new or renovated lawn.

Three questions before you pick a grass

How much sun does the area get? Watch it on a summer day. Dappled light under a maple counts for much less than open sun, and lawns that lost an ash tree may now get far more sun than they used to.
How will the lawn be used? Kids, dogs and a path to the garage need a grass that recovers from wear.
How much water and care will you give it? Some grasses need regular watering and feeding to look good; others are built to get by on less, which matters when your city limits watering days.

Before planting anything, get a soil test through the University of Minnesota Soil Testing Lab. It tells you pH and nutrient levels and is the only way you can legally justify phosphorus fertilizer on an established Minnesota lawn.

The main grasses for Twin Cities lawns

Kentucky bluegrass

Kentucky bluegrass is the classic Minnesota lawn and the grass in most sod grown in the state. It spreads by underground stems, so it fills in thin spots and recovers from wear. It looks its best in full sun with regular water and fertilizer. In a dry spell it goes dormant and turns tan, then greens up again when rain returns, which is normal rather than a sign the lawn has died. Its weaknesses are shade and low-input care.

Fine fescues

Fine fescues, a group that includes hard fescue, chewings fescue, creeping red fescue and sheep fescue, are the go-to grasses for shade and for lawns that get little water or fertilizer. University of Minnesota Extension publishes guidance on planting and maintaining fine fescue lawns, and university research has made them a focus for low-maintenance turf. They don't love heavy traffic or rich, overwatered conditions. For a shady lot under mature trees, a fescue-heavy mix with some shade-tolerant bluegrass is what Extension suggests.

Turf-type tall fescue

Tall fescue has a deep root system, handles wear and is a good option for sunny, lower-maintenance lawns. It grows in clumps rather than spreading much, so bare spots need overseeding. Extension lists turf-type tall fescue alongside fine fescue as a lower-maintenance option.

Perennial ryegrass

Perennial ryegrass germinates quickly and is common in seed mixes to give a fast cover. It handles traffic, but it can be less winter hardy in Minnesota, so it works best as part of a blend rather than on its own.

Pollinator or bee lawns

Some homeowners mix low-growing flowering plants, such as white clover, into a fine fescue lawn to support pollinators. The state's Lawns to Legumes program has offered grants and coaching for pollinator lawns and plantings in past funding rounds. Program terms change, so check with the Board of Water and Soil Resources for the current round.

Quick comparison

Full sun, regular care, family use: Kentucky bluegrass, or a bluegrass and ryegrass blend.
Shade or low water: fine fescue mix with some shade-tolerant bluegrass.
Sunny, lower maintenance, deep roots: turf-type tall fescue.
Dense shade: beds, mulch and groundcovers instead of turf.

When to seed

University of Minnesota Extension says the best time to seed a lawn is late summer, roughly mid-August to mid-September. Soil is still warm enough for fast germination, air temperatures are cooling, fall rain is more dependable, and weeds are slowing down. Young grass then has two cool seasons, fall and the following spring, to establish before its first summer.

Spring seeding works but is harder, because seedlings have little time to root before summer heat and crabgrass arrive. Dormant seeding is another option: Extension notes you can sow seed any time soil temperatures are below 40 degrees F, which for most of the state runs from early November to about mid-March. The seed sits in the soil over winter and germinates when conditions are right in spring.

When to lay sod

Extension notes that sod can be laid virtually any time during the growing season, as long as it can be watered. Late spring and late summer into early fall are the easiest windows. Midsummer installs need more water, which can run into your city's watering limits, and sod laid very late in fall has little time to root before the ground freezes. Most sod available here is Kentucky bluegrass, so it is a poor fit for heavy shade.

Preparing the soil

Remove existing weeds and old turf, or kill and remove them, before seeding or sodding.
Test the soil and add amendments based on the results, not guesswork.
Loosen compacted soil, common on new-construction lots in the suburbs, and work in organic matter where practical.
Grade so water flows away from the house and doesn't pond. Low spots turn into ice sheets in spring.
Firm the surface lightly with a roller before seeding or sodding.
Contact Gopher State One Call (811) at least 48 hours before tilling or grading, not counting the day of the request, weekends and holidays.

Fertilizer rules for new and existing lawns

Minnesota prohibits phosphorus fertilizer on lawns except in specific cases, and establishing a new lawn by seed or sod is one of them. That makes a new lawn the time to correct a phosphorus shortage if your soil test shows one. After that, phosphorus is only allowed when a soil or plant tissue test shows a need. Fertilizer that lands on driveways, sidewalks or streets must be cleaned up right away.

For established lawns, Extension's fertilizer schedules center on late summer and early fall, with an optional late spring application for higher-maintenance lawns. A low-maintenance lawn with clippings returned may need only a single September feeding.

Mowing and watering

Mow at 3 inches or higher. Extension notes taller mowing improves lawn quality and reduces watering needs. Remove no more than a third of the blade at once and leave clippings on the lawn. Water deeply and infrequently in the morning, and only when the lawn shows signs of drought. Follow your city's watering days, which differ around the metro. Extended droughts rarely kill an established lawn; dormancy is the grass protecting itself.

Bottom line

For most sunny Twin Cities yards, Kentucky bluegrass or a bluegrass blend is the standard choice. For shade and low-water lawns, fine fescue usually wins. Seed in late summer, test your soil first and respect the phosphorus law. If you'd rather have a pro evaluate the site and handle prep, request a landscaping company, or learn more about sod installation and lawn care in the Twin Cities.

Frequently asked questions

What grass grows best in shade in Minnesota?

Fine fescues are the most shade-tolerant common lawn grasses for Minnesota. University of Minnesota Extension suggests fescue mixes with shade-tolerant Kentucky bluegrass. In dense shade, beds or groundcovers usually work better than any grass.

Is spring or fall better for seeding a Twin Cities lawn?

Late summer to early fall, roughly mid-August to mid-September, is best according to University of Minnesota Extension. Spring seeding gives young grass little time before summer heat and crabgrass.

My bluegrass lawn turned brown in July. Is it dead?

Probably not. Kentucky bluegrass goes dormant during dry spells and greens up when rain returns. Extension notes that extended droughts rarely kill a lawn.
