When Does Pre-Emergent Season Really Start in Kansas City?

Kansas City winters like to keep us guessing. One day there’s snow on the ground, the next day it feels like spring is knocking on the door. That’s when the big question always comes up:

“Is it time for pre-emergent yet?”

The honest answer?👉 We’re already planning — and that’s why Turf Geeks usually starts in mid-February.

Snow on the Ground Doesn’t Mean We’re Late ❄️

Snow in January or February doesn’t change our plan.

That’s because:

• Snow doesn’t stop soil from warming underneath

• Air temperature doesn’t control weed germination

• Soil temperature is what matters most

Weeds like crabgrass don’t follow calendars — they follow consistent soil warmth.

The Real Trigger: 50° Soil Temps (Not the Calendar) 🌡️

Here’s the key Turf Geeks mindset:

We don’t wait for soil temperatures to hit 50°F for 5 straight days.We want protection in place before that happens.

Why? Because once soil temps stay near 50°F for about 5 consecutive days, weed seeds begin to germinate. And once they germinate, pre-emergent can’t stop them.

Kansas City Timing: What the Last 10 Years Tell Us 📊

Looking at Kansas City’s weather and soil temperature trends over the past 10 years, we consistently see that:

• The 5-day stretch of 50°F soil temperatures

• Usually occurs in late March to the first week of April

That’s why waiting until “it feels warm” is risky — soil temps can rise fast once winter breaks.

Why Turf Geeks Usually Starts in Mid-February

Our strategy is intentional, not early for the sake of being early.

📅 We usually begin pre-emergent applications in mid-February so:

• The product has time to activate

• A protective barrier is already in place

• Your lawn is covered before that late-March / early-April soil temp spike

Some years spring shows up early. Some years it takes its time.

But being prepared ahead of the germination window is how you win.

Why We Use a Split Application Approach 🌱

One of the biggest differences with Turf Geeks?

👉 We apply pre-emergent in split applications.

Here’s why that matters:

• First application: Lays the initial protective barrier early

• Second application: Reinforces and extends protection later into spring

• Helps prevent early breakdown

• Covers a longer germination window

Kansas City doesn’t warm up all at once — and neither should your weed protection.

This split strategy is critical for long-lasting, season-long control, especially with unpredictable Midwest weather.

Why Waiting Too Long Can Cost You

If you wait until:

• Weeds are visible

• Neighbors start treating

• Soil temps are already consistently warm

You’re already behind.

Pre-emergent is about prevention, not reaction.

How Turf Geeks Gets the Timing Right 🤓

We don’t guess — we monitor.

Our team tracks:

• Local Kansas City soil temperatures

• Multi-day trends (not single warm days)

• Long-term weather patterns

That’s how we protect lawns before weeds ever get started.

What Homeowners Should Do Right Now

Even with snow on the ground, now is the smart move to:

✔ Get on the schedule

✔ Lock in your lawn program

✔ Let the timing be handled for you

Because once soil temps start moving, things happen fast.

Final Thought 🌱

Pre-emergent season in Kansas City doesn’t start when weeds appear. It starts before soil temperatures consistently reach 50°F.

That’s why Turf Geeks usually starts in mid-February — and why we use a split pre-emergent application to extend protection and keep your lawn covered through spring.
