What Should You Be Doing for Your Lawn in April in Lincoln, Nebraska? | Yard Boss

Yard Boss • April 2026 • Lincoln, NE

If you are standing in your yard right now looking at brown, matted grass and wondering whether this thing is even alive, take a breath. That is completely normal for a Lincoln lawn in early April.

After months of freezing temperatures, dry winter winds, and the occasional ice storm, cool-season grasses like tall fescue and Kentucky bluegrass are just starting to wake up. They look rough right now. But what you do in the next few weeks will determine whether your lawn bounces back strong or struggles all the way through summer.

Here is what we would recommend focusing on this month.

Your Pre-Emergent Window Is Open (But Closing Fast)

This is the big one. If there is only one thing you take away from this article, let it be this: get your pre-emergent weed control down before soil temperatures consistently reach 55 degrees Fahrenheit.

In Lincoln, that window typically falls somewhere in late March through mid-April, depending on the year. Once soil hits that temperature, crabgrass seeds start germinating. And once they germinate, pre-emergent cannot stop them. You have missed the window.

Think of pre-emergent like an invisible barrier just below the soil surface. It prevents weed seeds from establishing roots. But it has to be in place before those seeds start growing. Timing is everything.

If you are handling this yourself, a soil thermometer is a worthwhile investment. Check your soil temperature at a depth of about two inches in a few different spots around your yard, ideally in the morning. If you are consistently seeing readings in the low 50s, it is time.

If you are working with a lawn care company, this should be part of your first application of the season. A good program will combine pre-emergent with a slow-release fertilizer and a spray for any weeds that are already actively growing, all in one visit.

First Fertilizer Application: Feeding the Wake-Up

Your lawn has been living off stored energy all winter. April is when it starts actively growing again, and it needs fuel.

A balanced, slow-release fertilizer applied in early to mid-April gives your grass the nutrients it needs to green up, fill in, and start building the root system that will carry it through summer heat.

Here is what we have found works best for Lincoln lawns: a slow-release formula that feeds over about 60 days. This avoids the “surge and crash” you get from quick-release fertilizers, where the lawn looks great for two weeks and then fades. Slow-release keeps things steady and promotes healthier growth over time.

One thing to keep in mind with Lincoln’s alkaline soil (our pH typically runs 7.5 to 8.5): iron supplementation matters. High pH locks up the iron that is already in the soil, which means your grass cannot access it even though it is technically there. That is why so many lawns in Lincoln turn yellow even when they are being fertilized. If your fertilizer program includes iron, you are in much better shape.

Assess the Winter Damage

Take a walk around your property and really look at what winter left behind.

Snow mold is a common one. You will see circular patches of matted, grayish or pinkish grass, usually in areas where snow sat the longest. The good news is that snow mold is mostly cosmetic for cool-season grasses. Rake those areas gently to break up the matted grass, improve airflow, and let new growth come through.

Bare or thin spots from desiccation are also common. Lincoln’s dry winter winds can pull moisture right out of exposed grass, especially on south-facing slopes and areas without snow cover. Mark these areas mentally. They are candidates for overseeding in the fall when conditions are ideal for seed establishment.

Also look for areas where water pooled or drained heavily during snowmelt. These spots may have compacted soil or eroded turf that will need attention later in the season.

Start Thinking About Pest Control

April is when the pest clock starts ticking. While you probably will not see heavy mosquito, tick, or flea activity yet, the populations are beginning to build.

If perimeter pest control is something you are interested in, mid-April is when most programs begin. A perimeter treatment (what we call Home Guard at Yard Boss) creates a barrier around your home’s foundation, entry points, windows, and doors that keeps ants, spiders, boxelder bugs, earwigs, and other crawling pests from getting inside. Home Guard runs $59 per monthly treatment from April through October.

For comprehensive outdoor pest control covering mosquitoes, ticks, fleas, and chiggers (what we call Yard Guard), most programs start in late April or early May, depending on temperatures. Yard Guard runs $79 per month and includes everything in Home Guard plus full yard coverage. If you have kids or pets who spend a lot of time in the yard, this is worth getting on the schedule sooner rather than later since spots can fill up fast in spring.

Mowing: Do Not Jump the Gun

We get it. The sun comes out, the grass starts greening up, and the urge to fire up the mower is strong. But here is a word of caution: do not mow too early if the ground is still soft and soggy.

Mowing on wet, soft soil causes compaction and ruts, both of which damage root systems and create long-term problems. Wait until the soil has firmed up and the grass has actually grown to the point where it needs cutting, typically when it reaches about 4 to 5 inches.

When you do start mowing, keep your blade height at 3.5 to 4 inches for both fescue and bluegrass. Taller grass means deeper roots, better drought tolerance, and natural shade that helps suppress weeds. It is one of the simplest things you can do for your lawn, and it costs nothing.

Emerald Ash Borer: Now Is the Time

If you have ash trees on your property, April opens the treatment window for Emerald Ash Borer (EAB). This invasive beetle has been confirmed throughout Lincoln and Lancaster County, and it kills 99% of untreated ash trees within two to four years.

The critical thing to understand about EAB is that treatment has to be preventive. By the time you see obvious symptoms like canopy thinning, D-shaped exit holes in the bark, or heavy woodpecker activity, the infestation is often too advanced to reverse.

Professional trunk injection is 95% or more effective when applied to healthy trees, and it protects for two full years. Compared to the cost of removing a large dead ash tree (often $2,000 to $5,000 or more), treatment is a fraction of the investment.

If you have been putting this off, April is your sign to get it scheduled.

What to Skip in April

Just as important as knowing what to do is knowing what not to do.

Do not overseed in spring. We know it is tempting when you see bare spots, but spring seeding in Lincoln competes with crabgrass germination, faces unpredictable late freezes, and forces new grass to survive its first summer with an immature root system. Fall (August 15 through September 30) is dramatically more effective. We have seen the difference hundreds of times, and it is not even close.

Do not aerate in April either, unless you have severe compaction that cannot wait. Spring aeration disturbs the soil right when pre-emergent needs an undisturbed barrier to work. Fall aeration gives you far better results for cool-season grasses.

What to Do Next

April sets the tone for everything that follows. A strong start with pre-emergent, fertilizer, and smart mowing practices builds a foundation your lawn can build on all season. A late or missed start often means playing catch-up through the summer.
