Don’t Let “Fake Spring” in the Midwest Trick Your Lawn
If you live in the Midwest, you’ve probably experienced it: a stretch of warm days in late winter that makes it feel like spring has arrived. Lawns start to thaw, neighbors start talking about mowing, and it’s tempting to jump right into lawn care season. But chances are… it’s just fake spring.
Fake spring happens when a brief warm spell arrives before winter has truly ended. Air temperatures rise for a few days, but soil temperatures are still cold and winter weather often returns shortly after. For your lawn, acting too early with fertilizer, weed control, or seeding can lead to wasted applications and less effective results.
Here’s how to avoid the fake-spring trap and set your lawn up for success when the real growing season begins.
Why Fake Spring Happens
Fake spring is common across the Midwest between late February and early April. A temporary shift in weather patterns pushes warm air north, creating a few comfortable days before colder weather returns.
The key thing to remember is air temperatures warm up much faster than soil temperatures.
Your lawn responds to soil temperatures—not the weather outside your window. Even if the grass starts to look slightly greener during a warm stretch, it may still be largely dormant below the surface.
Why Timing Matters for Weed Prevention
One of the most important early-season lawn care steps is applying a pre-emergent herbicide to stop weeds like crabgrass before they germinate. Pre-emergents, like Barricade®, are designed to create a protective barrier in the soil that prevents weed seeds from sprouting in the first place.
The key is timing. Pre-emergent should be applied before soil temperatures consistently reach about 55°F, which is when many summer annual weeds begin to germinate. Applying too early during a fake spring can shorten the window of protection later in the season when weeds actually begin to emerge.
What You Should Do During Fake Spring
Instead of rushing into lawn treatments, use this time to prepare for the real start of the season.
1. Watch Soil Temperatures
Soil temperature is the most reliable indicator of when to begin spring lawn care. As a general guideline:
-
45–50°F soil temps: Begin planning your pre-emergent application
-
50–55°F soil temps: Apply pre-emergent for crabgrass prevention
-
55°F+ soil temps: Weed seeds begin to germinate
When temperatures approach this range, it’s time to apply a pre-emergent like Barricade or a combination product such as Barricade® Plus Lawn Food 18-0-4, which provides both weed prevention and early-season nutrition.
2. Hold Off on Early Fertilizing
It’s tempting to fertilize your lawn as soon as warm weather arrives, but applying nutrients too early can push top growth before the grass is ready. Instead, wait until your lawn shows consistent green-up and active growth.
Products that combine pre-emergent weed control with fertilizer—like Barricade Plus Lawn Food 18‑0‑4—can be a great option once the timing is right, helping your lawn thicken up while preventing weeds at the same time.
3. Don’t Rush the First Mow
If your lawn starts growing during a warm stretch, keep the first few mows conservative. Maintain a mowing height around 3 inches or higher (for cool-season grass types) to protect the grass crown and reduce stress if temperatures drop again.
4. Prepare Your Lawn Care Plan
Fake spring is actually the perfect time to prepare for the season ahead.
Check your spreader, plan your product applications, and make sure you have the right products ready—whether that’s a standalone pre-emergent like Barricade or a full seasonal program like The Andersons Lawn Program.
Having everything ready ensures you can act quickly once soil temperatures reach the right range.
Patience Leads to a Better Lawn
Midwest weather can be unpredictable, and fake spring is just part of the cycle. Acting too early often leads to less effective weed control and wasted applications.
By waiting for consistent soil temperatures and stable weather, you’ll give your lawn the best chance to green up strong and stay healthy all season long.
When the real spring arrives, your lawn will be ready—and so will you.
