2026 Spring Homeland | Reseeding Right

Across the High Plains and the mountain West, thinning lawns are a common frustration. Homeowners often respond with more fertilizer, more water, or both — but those inputs alone don’t always solve the problem.

“Oftentimes when we start seeing yards thin in our region, they’re basically wore out,” said Michael Hays, owner of Buffalo Brand Seed located in Greeley, CO. “Most lawn grasses will not thicken back up with fertilizer and water. Overseeding those yards will actually help in that process of thickening, getting a greener yard.”

In the semi-arid West — where annual precipitation may range from 12 to 16 inches — reseeding is often the most effective long-term solution for struggling turf.

When Water isn’t Enough

In many Western communities, nearly every residential lawn relies on irrigation. But more water doesn’t automatically equate to healthier grass.

“Most homeowners are on a sprinkler system here,” Hays explains. “People will install sod, set the water to run three times a day, and then never change it. The grass sits there, anticipating being watered. It never roots down.”

Overwatering, especially in heavy clay soils, can weaken turf and increase compaction. Drought, soil compaction, and improper watering practices are among the most common causes of lawn decline. Winterkill can also be a factor when snow cover is limited, and plants lack moisture going into spring.

“When we see winterkill, it usually goes back to drought,” Hays said. “Without moisture, there’s nothing to support the roots. You lose trees, your yard — all of it — because of the lack of moisture.”

Reseeding allows homeowners to reintroduce vigorous varieties better suited to their climate and management practices, while also correcting soil issues that limit growth.

Timing Reseeding Correctly

In most Western regions, spring is prime time for reseeding anywhere from mid-March to mid-May. Ideal soil temperatures range from 45 to 60 degrees.

Those cooler soil temperatures allow the grass seed to germinate efficiently before the summer heat arrives. Seeding too late into warm weather increases water demands and reduces establishment success.

Soil Preparation: The Step You Can’t Skip

Ask Hays about the biggest mistake homeowners make, and his answer is immediate.

“The biggest key to overseeding or seeding a yard is seed-to-soil contact,” he said. “Without it, that seed just has nothing to latch on to, nothing to root into.”

Simply broadcasting seed over existing turf rarely works. Grass seed needs direct contact with soil — and should not be buried deeply. A quarter inch or less is ideal.

In compacted Western soils, core aeration is often the first step. Aerators punch into the soil and remove plugs, improving airflow, and creating openings for seed.

“With our soils being as heavy as they are, aeration is key,” Hays explains. “It punches the ground, pulls a plug out, gets air back into the soil, and gives you some seed-to-soil contact.”

For lawns with heavy thatch, power raking may be necessary before overseeding. Slit seeders — available through many rental outlets — can further improve germination by slicing into the soil and depositing seed directly.

“If we take our time and prepare the soil and work on getting that seed-to-soil contact, we’re going to have a greater chance of success,” Hays said.

Choosing the Right Seed for Success

Selecting the right species depends on elevation, water availability, traffic, and expectations.

“I always tell people you can start with the Cadillac, which is Kentucky bluegrass,” Hays said. “It’s the greenest, the finest blade, and the softest to walk on.”

Kentucky bluegrass offers an extended green window but requires higher water and maintenance inputs.

Tall fescue, increasingly popular in Western lawns, offers deeper roots and improved drought tolerance. Fine fescue blends reduce maintenance and water use even further, though they may not provide the same bright green appearance.

“Once you train your yard, you can have any grass you want,” Hays said. “You just have to train it to how much water you want to use and how much maintenance you want to give it.”

For homeowners seeking low-water alternatives, warm-season natives such as buffalo grass and blue grama are gaining ground.

“Buffalo grass can be watered maybe once a week if we’re dry — maybe once a month if we get moisture,” Hays said. “You’re going to mow it once or twice a month because it just doesn’t get very tall.”

The tradeoff is a shorter green season, as warm-season grasses green up later and go dormant earlier.

“Human nature, we always want the greenest,” Hays said. “But we can get there with other grasses and still use less water.”

Managing High-Traffic and Shaded Areas

Problem spots require realistic expectations and species adjustments.

“Bluegrass, for instance, does not do well in shade,” Hays notes. Shaded lawns may require specific shade-tolerant blends.

High-traffic areas often struggle due to compaction.

“To reseed, you’d have to get the traffic off of it,” Hays said. “Be honest about species that are wear-tolerant.”

Aeration combined with more durable varieties can help, but reducing traffic pressure is equally important.

Premium Seed vs. Bargain Blends

Not all grass seed is created equal. “Be sure to check the back of the bag,” Hays advises. “Make sure the seed in the bag is 100% what you want to purchase, not a mix of different species.”

Lower-cost seed may include fillers or varieties poorly adapted to local conditions. Blends formulated for your region often produce better long-term results.

“You get what you pay for,” he adds.

Long-Term Success for your Lawn

Reseeding doesn’t end once seedlings emerge. Establishment requires consistent moisture, balanced fertility, and patience.

“Fertilizer helps, but patience is key,” Hays said. “Take the right steps and don’t try to shortcut anything.”

Once grass has been mowed a few times, homeowners should gradually reduce irrigation frequency to encourage deeper roots.

“Don’t be afraid to turn off the water for a couple of days,” Hays said. “It won’t die. If anything, it will help the roots establish. Train the yard to match the watering schedule you desire.”

With proper preparation, thoughtful species selection, and disciplined management, reseeding can restore a lawn to health — even in the dry, demanding conditions of the West.
