Is Your Lawn Ready for Spring? It’s All About Soil Temperature! 
Kansas City weather is unpredictable, but when it comes to lawn care, soil temperature is what really matters—not just the air temperature. Whether you’re applying pre-emergent, fertilizing, or waiting for your lawn to green up, the right timing depends on soil temps.
In this guide, we’ll break down:
✅ What soil temperature means for your lawn
✅ How to check Kansas City soil temps in real-time
✅ The best timing for pre-emergents, fertilization, and weed control
✅ Why your lawn may be slow to green up in spring
​
🌡️ What Is Soil Temperature & Why Does It Matter?
Soil temperature is the actual temperature of the ground, measured a few inches below the surface. It determines when:
✔ Grass starts growing in spring
✔ Weeds like crabgrass germinate
✔ Fertilizer is absorbed properly
✔ Aeration & seeding are most effective
📌 Kansas City’s spring weather fluctuates, but soil temperatures change more slowly than air temps. That’s why a few warm days in March don’t mean your lawn is ready!

 What to Look For:
✔ If soil temps are 50-55°F, apply pre-emergent ASAP.
✔ If temps are 55-60°F, fertilize your lawn for a stronger spring green-up.
✔ If it’s 65°F+, summer weeds will start popping up—act fast!

Why Is My Lawn Greening Up Slowly?
If your lawn looks dull and patchy in early spring, don’t panic! It’s likely due to:
🔹 Soil temps being too low (grass won’t grow until the ground warms up)
🔹 Cool-season vs. warm-season grass differences (fescue greens up before zoysia)
🔹 Lawn stress from winter (compacted soil, snow mold, or drought damage)
​
What You Can Do:
✔ Check soil temps before applying fertilizer
✔ Avoid overwatering—wet, cold soil can cause root rot
✔ Aerate & overseed in fall to promote a thicker, healthier lawn
