Why Choosing the Right Grass Seed Matters – Especially in Minnesota

Posted on | by Organic Lawns by Lunseth

At Organic Lawns by LUNSETH we believe organic lawn care is about working with nature—not against it. And that starts with understanding the unique conditions of our state and selecting the right grass seed for the job. This month we review why the right seed matters, the best types of grass seed for Minnesota lawns, and red flags about generic seed mixes.

Minnesota’s Climate: A Lawn-Care Challenge and Opportunity

Minnesota lawns face a wide range of conditions throughout the year—icy winters, wet springs, humid summers, and dry spells in between. That means your grass seed needs to be hardy, adaptable, and suited for cool-season growth.

Unlike other parts of the country, Minnesota lawns do best with cool-season grasses—varieties that thrive in spring and fall, when temperatures are milder.

Why the Right Seed Matters in Organic Lawn Care

Organic lawn care relies on building long-term soil health and resilience. The wrong seed makes achieving those goals difficult by requiring more water, more fertilizers, or more pesticides—exactly what we’re trying to avoid.

Here’s why buying the right seed pays off:

  • Reduced Weed Pressure – High-quality, allelopathic, grass seed creates a thick, healthy lawn that naturally crowds out weeds..
  • Less Watering –  low-maintenance grass species require less irrigation.
  • Stronger Roots – The right grass seed means deeper roots, which equals better drought resistance and less stress.
  • Fewer Inputs – You won’t need to add synthetic fertilizers or harsh chemicals when your lawn is already thriving.

Top Grass Types for Minnesota Lawns

Our friends at the University of Minnesota Extension Service provide excellent guidance for choosing the right grass seed for your lawn.  Here are their recommendations.

Fine fescues

This species includes 5 fescues:

  • strong creeping red (most tolerant of tree shade)
  • slender creeping red
  • hard (the most drought-tolerant)
  • Chewings (most tolerant of tree shade)
  • Sheep (lowest maintenance)

Fine fescue is drought, shade, and salt-tolerant, but doesn’t do well in extreme heat. It has lower maintenance requirements, including less irrigation, mowing, and fertilizing. But, do not mow in the summer heat. Fertilize in the fall if needed.

A mix of strong creeping red, Chewings, and hard fescue is excellent for home lawns.

Tall fescue

Tall fescue is one of the most drought-tolerant turfgrasses for Minnesota due to deep, extensive roots. And it can be used in the shade. It also tolerates wear and traffic. Be patient, though, because it has a slow spring green-up.

Make sure to purchase turf-type tall fescues for lawns. Seeding in the spring helps the grass survive winter better in the first year. Do not plant in areas that hold ice in the winter.

Beware of Cheap or Generic Seed Mixes

Not all grass seed is created equal. Many big-box store brands contain:

  • Low germination rates
  • Invasive weed seeds
  • Species that don’t perform well in Minnesota’s climate

That’s why LUNSETH always recommend buying regionally appropriate, high-quality, and preferably certified organic grass seed from trusted suppliers. Our general rules include

  • When in doubt, buy the most expensive because it’s most likely to germinate
  • Don’t buy anything that includes unknown varieties
  • Try not to buy anything that says annual because it won’t overwinter
  • Look at the back of the seed bag and follow the below guidelines:

Purity > 85%
Germination > 85%
Weed seed < 0.3%
Other crop < 0.5%
Inert matter < 8%
Date tested = within the last 9-months

Hearty and Drought Tolerant Grasses

Posted on | by Organic Lawns by Lunseth

The Twin Cities has had consistent rainfall during the summer of 2025, with many of the storms being torrential.  Research shows that this is part of a new weather pattern created by climate change, and now we’re approaching the time of year when we can go for long stretches without significant rain. But you have options to help maintain your lawn during these extreme conditions.

Weather Extremes – More Rain & More Drought

The University of Minnesota Climate Adaptation Partnership predicts that as climate change continues, “we expect more frequent and intense heavy rain events, with long dry periods in between.” They go on to say that “the length of consecutive dry days (CDD) is projected to increase more in the Midwest than in any region in the United States, up to 25% by 2100. This means that if we historically expected a dry period to last 8 days, we might expect it to last 10 days in the end of this century. We also expect a decrease in overall summer precipitation and a decrease in light rain events, but an increase in moderate and heavy rain events.

Turf Options

This is the time when our yards are getting a combination of the most intense sunlight and extreme heat of the season.  Many grasses will reach their wilting point and will go dormant under these conditions.  Luckily, grasses won’t start to die until they have 40 days of no moisture. But there are many varieties of grasses that can tolerate these environments better, leaving you with a green lawn even during drought.

The University of Minnesota Extension Service recommends tall fescue and fine fescue for Minnesota lawns.  They state that “these grasses can remain green for at least 28 days without water. Tall fescue is especially known for its heat and drought tolerance.

“Among the fine fescues, hard fescues have excellent drought tolerance. Chewings fescue and slender creeping red fescue have good to excellent drought tolerance. And strong creeping red fescues have good drought tolerance.”

Maintaining New Lawns

Posted on | by Organic Lawns by Lunseth

Last month we reviewed the process for a sustainable lawn renovation.  This month we provide tips to give your new yard its best chance of thriving. The University of Maryland Extension provides excellent guidance.

Watering

  • Once seed germination has begun do not let the seed dry out
  • A newly seeded lawn requires daily watering during dry periods. 
  • If there’s a stretch of windy and dry days, your grass may require several light waterings a day.
  • Sandy soils dry out quickly, require more watering, and using a light mist is best.
  • Mature grass seedlings require less frequent watering, but they should be watered longer when you do.
  • It’s best to water earlier in the day so the grass does not remain wet overnight.

Mowing

  • Mowing lawns too short or infrequently causes grass to become susceptible to drought injury, weed infestations (especially crabgrass), and foot traffic injury.
  • Mow new turf when it reaches a height one-third higher than your normal mowing height. Usually this is four to six weeks after seeding.
  • Remove only one-third of the grass’s height in each following mowing. Removing too much of the leaf blade at each cutting stresses the new lawn.
  • Soil should be dry enough so that ruts are not formed by the wheels of the lawnmower.
  • Mowing typically needs to be done on a weekly basis during the growing season.

Fertilizing

  • Follow-up applications of fertilizer are made as part of a regular maintenance program.  
  • Organic Lawns by LUNSETH’s organic fertilizer solution provides a proven alternative to chemically-based lawn care — delivering a number of benefits that aren’t possible when treating your lawn synthetically. Being 100% organic means our fertilizers contain a purely balanced food source and do not feature synthetic chemicals that can be detrimental to your health and harsh on your lawn. By hiring us to apply our 100% OMRI-certified organic fertilizer to your lawn, your grass won’t just look great, it’ll be healthy in a way that’s very environmentally advantageous.

Weeds

  • Weeds have been resting all winter and can’t wait to shoot through and start growing.  Thin or bare soil areas combined with sunlight and warm soil temperatures create a perfect opportunity for germination of many of our annual weeds. 
  • These weed seeds aren’t just perennials that lay dormant over the winter. They can be blown in by the wind or be carried in by our bird friends. Early spring is the time to start looking for these intruders and taking steps to reduce their spread. 
  • Read LUNSETH’s Blog Post, “Handle Spring Weeds Now or Pay the Price Later”, to learn about some of the most common weeds we see in Minnesota, along with our tips for getting them under control.

Traffic

  • Young seedlings are easily injured. Newly seeded areas should be restricted from foot traffic for a least a month after the seed has germinated or until the new lawn has been mowed at least a couple of times.

Identifying and Controlling Grub Damage

Posted on | by Organic Lawns by Lunseth

Grubs have become a real nuisance the past few years. LUNSETH addresses this issue in a number of communities throughout the Twin Cities. How do you know if you’ve got grubs or not?  Our friends at the University of Minnesota Extension Service have excellent information and suggestions for handling grubs..

Identifying Grub Damage

There are several indications that white grubs are damaging your lawn. These include:

  • Irregular patches of dead or dying grass that resemble drought stress.

  • Early signs of a white grub infestation are apparent when an irrigation system has been running or we have had regular rainfall and the drought symptoms are still present.

  • Moderate grub damage involves observing dead or dying turf with little to no roots when pulling on the turf.

  • More severe white grub damage is sometimes not caused by the grubs themselves, but by animals like racoons and skunks turning over the turf to feed on the grubs.

Controlling Grubs

What can you do about grubs? The good news is there are very effective organic solutions to get them under control. The Turfgrass newsletter references a biological insecticide, GrubGone (Baccilus thuringiensis galleriae), as the only known biological insecticide to work effectively. It works as a preventative treatment and needs to be applied in advance of a white grub infestation.

Preparing Your Lawn for Spring Topic #1: Snow Mold

Posted on | by Organic Lawns by Lunseth

It seems odd to think about taking care of your yard during February in Minnesota. But now is a great time to start planning your lawn care for the upcoming spring, especially if you’re focused on organic lawn care. 

For the next few months, LUNSETH will provide details (with information from the University of Minnesota Extension Service) about common challenges for Minnesota yards, and the recommended organic solutions to deal with them.

What is Snow Mold

When the snowmelt is on and we start to see our lawns appear in Minnesota, most yards have some, or a lot, of snow mold. It’s typically circular patches of matted, greyish grass up to 3 feet in diameter. 

U of M Extension describes snow mold as “…a fungal disease that can be caused by 3 different pathogens (Typhula spp. and Microdochium nivale). All Minnesota lawn grasses can be affected, although fine fescue grasses are less susceptible. Snow mold disease damages grass leaves but usually will not kill the entire plant.” 

Repairing Grass with Snow Mold

Snow mold might look bad, but it shouldn’t permanently damage the lawn. To promote recovery, lightly rake these areas to loosen the matted leaves. Make sure to lift the matted grass completely to let air circulate in that part of the lawn. No chemicals – just a little effort. It doesn’t get any more organic than that.

Timing is important, too. You need to stay off of the lawn until it has a chance to dry out.  Foot traffic on wet, damaged grass can cause even more damage. And, you especially DO NOT want to rake up the snow mold when it’s wet because you’ll end up pulling out your grass plants. Then you’ll have to seed the lawn if you want grass to return.  

Preventing Snow Mold Next year

There are a couple of simple steps to take at the end of the growing season to try and prevent snow mold next spring. First, continue to mow your turf well into the fall.  Second, when snow does come, avoid creating large, long-lasting snowbanks on your grass when shoveling snow from your sidewalks and driveways.

Conclusion

February might feel like the dead of winter in Minnesota, but it’s the perfect time to start planning for a healthy, organic lawn this spring. By planning and scheduling your organic lawn care treatments today, you’ll be ahead of the game when the warm weather finally arrives.

Remember, organic lawn care is all about nurturing the health of your lawn and the environment. By taking small steps now, you’re not only preparing your lawn for a successful year but also creating a sustainable, eco-friendly outdoor space for your family to enjoy. Let’s make this year’s lawn care routine as green and healthy as possible!

Rake or Mulch in the Fall?

Posted on | by Organic Lawns by Lunseth

Many people are obsessed with raking their yards to look like freshly vacuumed carpets. This approach can be stressful and time-consuming. While it’s important to make sure your grass isn’t covered with leaves going into the winter, the good news is there are benefits to not leaving your yard spotless.

A little leaf coverage is good, but not too much

The University of Minnesota’s Turfgrass Science Program provides helpful guidelines for dealing with your fall leaves.  They say the most important point with fall cleanup is that the tree leaves are not covering a significant portion of your yard. Too many leaves on your lawn going into winter is harmful.  Leaves smother the grass and inhibit growth in the spring.  Leaves covering your grass also promote snow mold diseases.  And, a layer of leaves makes an attractive habitat for voles and mice and they can cause turf damage over the winter. They recommend leaving 10-20% coverage of your lawn.

Rake, bag or mulch? Mulch!

The three options to take care of leaves are raking, bagging, or mulching. The Turfgrass Science program explains why mulching is the most beneficial for your yard.  Mulching the leaves with a mower incorporates beneficial nutrients and organic matter into the lawn and soil.  Some leaf types, like maples, have even been shown to reduce weed seed germination when mulched into a lawn.  The leaves of honey locusts may add a significant amount of nitrogen to lawns. Their leaves fix nitrogen from the atmosphere just like soybeans, so higher leaf nitrogen contents in these leaves transferred to the soil is possible. 

Successful mulching requires chopping leaves into small pieces. This requires more frequent mowing in the fall, and you may need to do multiple passes with the mower to mulch the leaves sufficiently. 

If you do choose to rake or bag your leaves, make sure to compost them.

Aerate & Overseed Now!

Posted on | by Organic Lawns by Lunseth

Aerating and overseeding your lawn now is an important way to give your grass a jumpstart on next year’s growing season.


Aeration

All yards become compacted, and a yard that’s used a lot gets compacted a lot more! That’s one of the reasons why aeration is one of the most important services you can do for your lawn. The University of Minnesota Extension Service says that between late August and early October is the best time to aerate – so now is the time! Fall is an ideal time to aerate because the grass is still actively growing, but there’s less danger of spreading seeds from weeds during the process. 

There are several benefits of aeration. It improves the lawn’s health and relieves soil compaction, resulting in better water drainage and nutrient absorption by the roots.  Strong roots are essential for healthy grass. Also, plugs of soil from the ground are created during aeration. This allows air, water, and nutrients to penetrate the soil and reach the lawn’s root system.

Compacted soils and soils with poor drainage accumulate thatch faster than well-drained soils. Aerification stimulates the microbial activity involved in decomposing the thatch layer. Aeration plugs sit on the surface of the lawn and crumble apart over time. This top-dresses the grass with soil containing desired microorganisms that will work at decomposing thatch.


Overseeding

Fall is on the best time to overseed. Establishing grass now means it has less competition with weeds, and the cooler nights and sunny days allow for the successful germination of our cool-season grasses. In addition, immature grass does better over the winter than it does dealing with the stresses of summer. So getting it started in the fall optimizes its ability to establish in the spring.

Overseeding after aeration is great timing.  The holes created by the aeration process become great places to catch and protect the seed. And, the lawn is less compacted after aeration, giving the grass a better chance of rooting into the soil.

If you have a question about aeration and overseeding, or would like a quote for having your yard aerated, contact the experts at Organic Lawns by LUNSETH.

Winter Love for Untidy Lawns & Gardens

Posted on | by Organic Lawns by Lunseth

A yard without leaves and a garden without dead stalks sticking up all winter long brings a sense of satisfaction. But at Organic Bob we promote a love of untidy lawns and gardens. These organic materials serve to nurture the soil and also provide shelter for pollinators.

Our friends at the Pollinator Friendly Alliance explain that most pollinators stay over winter, looking for shelter in both plants and the ground. “During cold months, dead plant stems, old bark, cane, leaves, and undisturbed soil are the secret winter homes of pollinators. Leaving piles of leaves, compost or wood help all manner of creatures including salamanders, beneficial insects, and pollinators. Many solitary bees like mason bees burrow under tree bark or wood piles. Some have gorged like bears to make it through the winter; others wait in suspended animation as larvae, pupae, or eggs.

“Something you should be aware of as you begin to tidy up your garden for winter – especially burning or removing the plant stems, you may be destroying hibernating bees or bee nurseries. So, it’s important to leave plants standing until late spring when temperatures rise and nectar and pollen is available.”

If you have a question about keeping a pollinator friendly yard, contact the experts.
