Why Is My Grass Patchy? A Guide to Reviving Sherman Lawns

You take immense pride in your yard, investing time and effort into mowing and watering—yet frustratingly, large brown or thin spots still dominate the turf. Why is this happening?

When your grass is thin and not doing well, it undercuts the pride you feel in your home and leaves you feeling stuck, wondering what more you can possibly do. This is often the moment homeowners realize that effective Lawn management goes far beyond basic mowing and watering.

The simple truth is this: patchy grass is not a surface problem. It’s a symptom of deeper, structural issues that mowing alone cannot fix. These issues often include chronic nutrient deficiencies, aggressive weed competition, and localized pest or disease damage.

At North Texas Turf and Lighting (DBA NTX Turf Management), we are state-licensed experts equipped to diagnose the real causes of patchy lawns and apply professional, proven solutions. Our Lawn management approach uses products and techniques that are wider and better than anything available in a store.

In this guide, we’ll:

Diagnose the three primary causes of patchy grass in Sherman
Explain why DIY efforts often fail
Present the professional solution that restores a thick, uniform, green lawn

III. Diagnosis: What Causes Thin & Patchy Grass?

Patchy turf happens when grass loses its competitive edge against one or more destructive forces. In the Sherman area, the most common causes are nutrient imbalance, weed pressure, and undetected pests or disease—issues professional Lawn management is designed to solve.

A. Why does my grass look thin and not green, even if I fertilize it myself?

If your grass looks thin and lacks color even after fertilizing, it’s usually due to chronic nutrient deficiency combined with inferior products or improper application.

To truly correct thin turf, professional-grade fertilization is required.

Here’s the difference:

Store-Bought Products

Generic fertilizers (often ~$60 per bag)
Lack precise, slow-release nutrient ratios
Easy to misapply, causing uneven feeding or burned patches

Professional, Licensed-Grade Products

Accessible only to licensed professionals
Contain optimized macro- and micronutrients
Designed specifically for North Texas soil and grass types

Because Michael is licensed through the state, our Lawn management programs use custom-formulated products that feed roots deeply and restore rich green color—systematically fixing the root cause of patchiness.

B. Can excessive weeds cause bare spots and patches in my lawn?

Yes—excessive weeds are one of the leading causes of patchy and bare lawns.

Aggressive weeds act as silent invaders, stealing:

Sunlight
Water
Essential nutrients

When homeowners say they “have a ton of weeds,” it usually means weeds are actively killing the grass in those areas. The result is turf that looks weak, thin, and unable to recover on its own.

The professional solution requires two steps:

Elimination
Aggressive post-emergent weed control removes existing weeds.

Prevention
Timely pre-emergent applications stop new weeds from germinating in exposed soil.

If weeds are overwhelming your lawn, you can Get started now with a program that combines weed control and fertilization for long-term recovery.

C. Are pests or diseases responsible for the dead brown spots in my turf?

Yes—pests and diseases are often responsible for dead brown patches, and homeowners frequently don’t realize it.

Many patches that don’t respond to water or fertilizer are caused by localized damage below the surface—another reason professional Lawn management is critical.

Common issues we treat include:

Fire ants, which damage turf structure
Grubs & root-feeding insects, which destroy roots and cause turf to lift
Fungal diseases like brown patch and dollar spot

DIY products often miss or misdiagnose these problems. Professional care allows for accurate diagnosis and immediate treatment, preventing the damage from spreading.

IV. Solution: Reviving Your Lawn with Professional Care

Once the root cause—nutrients, weeds, or pests—is identified, the solution becomes clear: replace guessing with a structured, phased plan.

D. What is the plan for reviving a lawn that is already patchy and thin?

Reviving a patchy lawn requires a dual-focus strategy: remove destructive elements and rebuild turf health with consistent nourishment.

Our proven revival plan includes:

Soil & grass type assessment
Immediate weed elimination
Professional-grade fertilization
Long-term weed prevention

This entire process is built into our 7-Step Lawn Care Program. Homeowners ready for a real turnaround can Get started now with a proven, licensed solution.

E. How do professional fertilization products fix nutrient-deficient patches?

Professional fertilization works because it is:

Precisely applied
Custom-blended
Designed for North Texas clay soil

These treatments encourage healthy surrounding grass to spread and fill thin areas naturally. With proper timing and application, professional Lawn management delivers faster recovery, deeper roots, and a dense, uniform lawn.
