Zoysia Lawn Care Program – Colleyville, TX

9 Applications Per Year

Built Specifically for Colleyville’s High-pH Clay Soils


Zoysia can look incredible in Colleyville—tight, dense, dark, and uniform—but only when it is managed correctly.


Most Zoysia problems here come from high-pH clay soils, improper mowing height, thatch buildup, overwatering, disease pressure, and programs designed for Bermuda instead of Zoysia.



Gro Lawn’s 9-round Zoysia program is built specifically for this grass type using real soil data, proper mowing standards, controlled nutrition, thatch management, selective weed decisions, and built-in disease prevention.


Zoysia Looks Great — But It Is Not Low Maintenance

Zoysia can look incredible in Colleyville—tight, dense, dark, and uniform—but only when it is managed correctly.


It is often marketed as “low maintenance,” but in Colleyville that mindset can slowly destroy Zoysia lawns.


Zoysia needs short mowing, controlled nutrition, aggressive thatch management, selective weed decisions, and timing that matches the season.



Gro Lawn does not treat Zoysia like Bermuda. We do not treat it like St. Augustine.

Zoysia Lawn Care in Colleyville Isn’t

One-Size-Fits-All

Every Zoysia lawn in Colleyville is dealing with a different mix of sun exposure, mowing habits, irrigation, drainage, thatch, soil conditions, and disease pressure.


That is why generic lawn programs fall short.


Zoysia needs a different strategy: shorter mowing, cleaner canopy management, restrained nutrition, selective weed control, and decisions based on the condition of the lawn—not a one-size-fits-all schedule.



This program is built specifically for how Zoysia behaves in North Texas, so your lawn can stay dense,

Things to Know About Zoysia in Colleyville

  • Zoysia builds thatch quickly when mowed too tall.
  • Taller mowing does not improve drought tolerance.
  • Excess height traps debris, moisture, and disease.
  • Zoysia responds best to short, clean, frequent mowing.
  • Spring and fall timing matter more than total fertilizer applied.


This program is designed to keep the canopy clean so Zoysia can perform in Colleyville’s high-pH clay soil and North Texas climate.

Recommended Mowing Standards

Zoysia performance depends heavily on mowing height and frequency.


Overall height:
1–2 inches


Thin-bladed Zoysia
Emerald, Trinity, Zeon, and similar varieties perform best with a reel mower at 1 inch or lower.


Rotary mower option
When a reel mower is not available, mow at 1.5–2 inches.


Wide-bladed Zoysia
Palisades, JaMur, and similar varieties should generally be maintained at 1.5–2 inches.


Mowing taller does not improve drought tolerance. It accelerates thatch buildup, traps moisture, and leads to long-term decline.

Power Raking & Thatch Management

Zoysia must be power raked.


For healthy Zoysia in Colleyville, we recommend power raking 1–2 times per year.


Spring power raking is especially important. Fall power raking may also be needed when thatch is heavy.

Power raking helps:


  • Remove trapped thatch and debris
  • Improve oxygen flow and soil contact
  • Reduce moisture buildup and disease pressure
  • Help water and fertilizer reach the root zone


Skipping this step is one of the most common reasons Zoysia lawns decline in Colleyville.


Zoysia performs best when the canopy is kept short, clean, and open.


New Zoysia Sod — Starter Strategy


New Zoysia sod is never treated like an established lawn.


Starter treatments depend on the time of year, growth stage, and how well the sod has rooted.


During the growing season, we begin with a Rescue Blend to support rooting and recovery.


We do not apply weed control until the lawn has been mowed 2–3 times. This helps prevent stress and protects immature roots and stolons.


During dormancy or the off-season, we begin with granular elemental sulfur and focus on soil conditioning and pH management—not top growth.



This approach helps protect new sod, improve establishment, and prevent setbacks caused by rushing herbicides too early.


What to Do Before Your Lawn Wakes Up in Spring

Early green-up does not come from early fertilizer.


It comes from proper preparation before the growing season starts.


For Zoysia, that means keeping the canopy short, clean, and open so sunlight, oxygen, water, and nutrients can reach the soil and roots.



This spring-prep approach helps reduce thatch problems, improve soil warming, lower disease pressure, and prepare the lawn to respond properly once growth begins.

This is the same approach we use to prepare Zoysia lawns for the growing season in Colleyville.

Our 9-Round Zoysia Program

Gro Lawn’s Zoysia program is designed around short mowing, thatch control, restrained nutrition, selective weed decisions, disease prevention, and long-term soil health.


Each round has a specific purpose. Some focus on weed prevention, some on careful nutrition, and others on soil correction or seasonal protection.



We do not treat Zoysia like Bermuda, and we do not run a one-tank, one-schedule program.

Important Zoysia Difference — Spring Weed Control

We do not blanket-spray post-emergent herbicides on established Zoysia lawns in the spring.


Zoysia gains an advantage when it is not unnecessarily stressed.


Our equipment allows Zoysia lawns to be treated with or without visible weeds, instead of forcing every lawn to receive the same tank mix.


This restraint is intentional—not an oversight.

  • Round 1 – Winter Weed Prevention

    This dormant-season application focuses on winter weed prevention and soil support—not growth.


    Specticle® pre-emergent helps prevent winter weeds before they emerge, while sulfate of potash supports stress tolerance.


    No nitrogen or micronutrients are applied during this stage because Zoysia is dormant.

  • Round 2 – Extended Pre-Emergent Protection

    A second Specticle® application combined with:


    • Nitrogen
    • Potassium
    • North Texas MicroPak (iron, manganese, zinc, and key micronutrients)

    Most companies skip feeding here—we don’t.

    Early nutrition produces a thicker, more even green-up and improves early weed suppression.



  • Round 3 – Spring Density & Color

    Once Zoysia is actively growing, the program shifts into measured spring nutrition.


    A 12-3-6 proprietary Zoysia blend, humic acid, and Colleyville MicroPak™ support density, color, and nutrient availability in high-pH clay soils.


    Best results occur when this round is paired with spring power raking and proper mowing.

  • Round 4 – Early Summer Support

    This round provides steady nutrition as Zoysia moves into early-summer growth.


    A 12-3-6 proprietary blend, humic acid, and Colleyville MicroPak™ help support density without overfeeding or increasing thatch.


    The goal is controlled growth, not excessive top growth.

  • Round 5 – Summer Stability

    Another application of our proprietary 12-3-6 blend with humic acid and micronutrients.


    Helps Zoysia handle:


    • Heat
    • Irrigation stress
    • Wear and traffic

    Maintains color and density through peak summer.

  • Round 6 – Late-Summer Support

    A continued application of our proprietary 12-3-6 blend with humic acid and micronutrients.


    Plus preventative fungicide targeting:


    • Brown Patch / Large Patch

    This reinforces root strength and prepares the lawn before fall disease pressure begins.

  • Round 7 – Fall Pre-Emergent + Disease & Nutsedge Control

    A liquid Specticle® pre-emergent plus Avenue South for broadleaf weeds, combined with:


    • AMS
    • SOP
    • North Texas MicroPak
    • Propiconazole (disease control)

    Prevents fall weeds while protecting against Large Patch as conditions cool.

  • Round 8 & 9 – Winter Weed Prevention + Long-Term Soil Health

    Rounds 8 and 9 are applied together.


    Specticle® pre-emergent provides strong winter weed prevention, while granular elemental sulfur supports long-term soil pH management in Colleyville’s high-pH clay soils.


    No nitrogen is applied during this stage.


    The purpose is winter weed prevention, soil correction, and long-term lawn health—not color or growth.

The Truth About Zoysia in Colleyville

Zoysia is a full sun grass.


It can tolerate some shade—but not heavy shade long-term.


In shaded areas, it will thin out and often get overtaken by Bermuda.


If your lawn has:

  • Dense tree cover
  • Poor drainage
  • Constant moisture



Those issues need to be addressed alongside any treatment program.


We believe in being upfront so you know what to expect and can make the right decision for your lawn.
