Question 1

When should pre-emergent be applied in DFW?

Accepted Answer

Pre-emergent herbicide should be applied in February to early March in the DFW area, before soil temperatures consistently reach 55 degrees Fahrenheit. This is the critical window — apply too late and crabgrass and other summer annuals will already be germinating. A second pre-emergent application in September or October prevents winter annual weeds like henbit and chickweed.

Question 2

What are the most common weeds in Fort Worth lawns?

Accepted Answer

The most problematic weeds in DFW lawns include crabgrass, dallisgrass, nutsedge (nutgrass), dandelions, clover, henbit, chickweed, and spurge. Nutsedge is especially persistent in North Texas because it thrives in the heat and reproduces through underground tubers that survive herbicide treatment of the visible plant. See our North Texas weed identification guide for photos and treatment strategies for each species.

Question 3

How many weed control treatments do I need per year?

Accepted Answer

Most DFW lawns need 3 to 4 weed control applications per year for effective management. This typically includes a pre-emergent in February-March, a post-emergent spot treatment in late spring, a summer nutsedge treatment as needed, and a fall pre-emergent in September-October. Lawns with severe weed pressure may need additional treatments.

Question 4

Is weed control safe for pets and children?

Accepted Answer

Modern professional-grade herbicides are formulated to target specific weed types while being safe for established turf. We recommend keeping pets and children off treated areas until the product dries completely, which typically takes 1 to 2 hours. We use granular products when possible, which adhere to leaf surfaces rather than leaving residue on the soil.

Question 5

How Much Does Weed Control Cost?

Accepted Answer

1,000-5,000 sq ft: $30 – $80 | 5,000-10,000 sq ft: $65 – $125

Question 6

When Should You Apply Pre-Emergent Weed Control?

Accepted Answer

Pre-emergent herbicide creates a chemical barrier in the top layer of soil that prevents weed seeds from germinating. In the DFW area, the critical spring application window is February to early March — before soil temperatures consistently reach 55 degrees Fahrenheit. Miss this window by even two weeks, and crabgrass, dallisgrass, and other warm-season annuals will already be sprouting. Once you can see the weed, pre-emergent is useless against it. A second pre-emergent application in September

Question 7

What Common DFW Weeds Does CARE Treat and How?

Accepted Answer

North Texas has year-round weed pressure thanks to mild winters. Crabgrass is the most common summer annual — prevented by properly timed pre-emergent and treated post-emergently with selective herbicides when breakthrough occurs. Dallisgrass is a perennial grassy weed that forms clumps and is notoriously difficult to control; it requires targeted post-emergent applications and sometimes spot removal. Nutsedge (commonly called nutgrass) thrives in DFW summer heat and reproduces through undergrou

Question 8

How Does Post-Emergent Spot Treatment Work?

Accepted Answer

Even with perfect pre-emergent timing, some weeds will break through. Post-emergent herbicides kill actively growing weeds while leaving your established turf unharmed. We use selective herbicides matched to both the weed type and your grass type — this matters because products safe for Bermuda can damage St. Augustine, and vice versa. Spot treatment targets individual weeds or weed patches rather than broadcasting across the entire lawn, which reduces chemical usage and cost.

Question 9

What Weed Control and Fertilization Programs Does CARE Offer?

Accepted Answer

Weed control and fertilization work together. A thick, healthy lawn is the best weed defense because dense turf physically blocks sunlight from reaching weed seeds in the soil. Our combined weed and feed programs bundle pre-emergent with the first spring fertilization round, delivering two critical treatments in a single visit. Paired with proper mowing at the correct height and annual aeration to reduce compaction, a well-executed weed control program can reduce weed populations by 80 to 90 per

Accepted Answer

North Texas has year-round weed pressure. Identifying each species correctly determines which treatment approach works and which wastes money.

Question 12

What Makes Crabgrass the Most Common Summer Weed in DFW?

Accepted Answer

Crabgrass is a summer annual that germinates from seed when soil temperatures consistently reach 55 degrees Fahrenheit, which in DFW occurs in late February to March depending on the year. It grows aggressively through spring and summer, produces thousands of seeds before dying with the first frost, and those seeds germinate the following year. Crabgrass is most damaging in thin or bare areas of the lawn where it can establish and spread laterally before the turf closes in. Pre-emergent herbicid

Question 13

Why Is Dallisgrass Harder to Control Than Crabgrass?

Accepted Answer

Dallisgrass is a perennial grassy weed that forms persistent clumps in lawn turf and does not die with the first frost like annual weeds. It spreads through both seeds and rhizomes (underground runners), which means killing the visible portion does not prevent regrowth from root structures in the soil. Dallisgrass clumps are visually distinct — coarser, lighter-colored, and faster-growing than surrounding turf, creating an uneven, unkempt appearance even in otherwise well-maintained lawns. Effec

Question 14

What Makes Nutsedge So Difficult to Eliminate in DFW?

Accepted Answer

Nutsedge (commonly called nutgrass) is technically a sedge rather than a true grass, and it thrives specifically in the wet conditions and summer heat that characterize DFW spring-summer weather. Its persistence comes from underground tubers called nutlets that can remain viable in the soil for years. Standard herbicides kill the visible plant but not the nutlets, and each tuber can produce multiple new plants the following season. Specialty sedge herbicides targeting the tuber system are requir

Question 15

Which Broadleaf Weeds Are Most Common in DFW Turf?

Accepted Answer

Dandelions, white clover, spurge, and oxalis are the most common broadleaf weeds in North Fort Worth lawns. Dandelions emerge in cool weather (October through April) and are controlled by post-emergent broadleaf herbicides. White clover indicates nitrogen deficiency in the lawn — it fixes its own nitrogen from the air and outcompetes nitrogen-hungry grass in underfertilized turf, making improved fertilization the underlying fix. Spurge is a low-growing summer annual that spreads aggressively in

Question 16

What Are Henbit and Chickweed and When Do They Appear?

Accepted Answer

Henbit and chickweed are winter annual weeds that germinate in fall from seeds deposited the previous spring, grow through the winter, flower and set seed in early spring, then die as temperatures rise. They are the primary targets of the fall pre-emergent application in September-October. Without fall pre-emergent, these weeds can carpet DFW lawns during winter months, creating a maintenance challenge and a large seed bank that carries forward into subsequent years. Both are easy to control wit

Question 17

Why Does Lawn Density Prevent Weed Establishment?

Accepted Answer

A dense, healthy lawn is the most durable long-term weed barrier available. Dense turf physically blocks sunlight from reaching soil-level weed seeds, preventing germination. Thick canopy roots also compete aggressively for soil moisture and nutrients, disadvantaging shallow-rooted weed seedlings that emerge in the brief windows between mowing cycles. Lawns with severe weed pressure almost always have an underlying problem — compaction, improper mowing height, inadequate fertilization, or irriga

Question 18

What Is Annual Bluegrass and When Does It Invade DFW Turf?

Accepted Answer

Annual bluegrass (Poa annua) is a cool-season annual weed that germinates in early fall when soil temperatures drop below 70 degrees Fahrenheit, grows through winter as a light-green, fine-textured patch, and dies in spring as temperatures rise. It is particularly visible in dormant Bermuda lawns where the contrast between the green annual bluegrass and the brown dormant turf makes infestations stand out. The fall pre-emergent application in September-October is the primary control tool, timed t

Question 19

How Does Clover Indicate a Soil Fertility Problem?

Accepted Answer

White clover in a lawn is often a symptom rather than just a weed. Clover fixes atmospheric nitrogen through root nodules, giving it a competitive advantage over grass that depends entirely on applied fertilizer in nitrogen-deficient soil. Lawns with widespread clover infestation almost always have inadequate nitrogen fertility levels. Applying broadleaf herbicide eliminates the visible clover but does not address the nitrogen deficiency, which means the clover will return within a single growin

Question 20

How Does Pre-Emergent Herbicide Work in DFW Clay Soil?

Accepted Answer

Pre-emergent is the most cost-effective weed control tool available — but only when timed precisely to the DFW soil temperature calendar.

Question 21

What Is the 55-Degree Soil Temperature Trigger?

Accepted Answer

Pre-emergent herbicide is most effective when applied before soil temperatures reach 55 degrees Fahrenheit at a 2-inch depth. This is the threshold at which most warm-season annual weeds, particularly crabgrass, begin germinating. In the DFW area, this threshold is typically crossed between mid-February and early March, though the exact date varies by 1 to 3 weeks from year to year depending on the winter weather pattern. We monitor local soil temperature data from the Texas A&M AgriLife weather

Question 22

How Does Clay Soil Hold Pre-Emergent Herbicide Longer Than Sandy Soil?

Accepted Answer

Clay soil has a high cation exchange capacity that binds pre-emergent herbicide molecules to soil particles more effectively than sandy soil. This means pre-emergent applied to DFW clay soil maintains its barrier effectiveness for a longer period — typically 6 to 12 weeks depending on the specific product and application rate — compared to sandy soils where leaching reduces effectiveness more quickly. This characteristic actually works in our favor in DFW: a well-timed spring application maintai

Question 23

Why Is the Fall Pre-Emergent Application Equally Important?

Accepted Answer

Many homeowners focus on spring pre-emergent and overlook the fall application, but North Texas has significant cool-season weed pressure from September through March. Henbit, chickweed, annual bluegrass, and rescuegrass all germinate when soil temperatures drop below 70 degrees in fall. The September-October pre-emergent application window prevents these weeds from establishing during Bermuda and St. Augustine's winter dormancy period when the turf cannot compete. A lawn with visible winter wee

Question 24

Does Pre-Emergent Need to Be Watered In After Application?

Accepted Answer

Granular pre-emergent products require 0.5 to 1 inch of water within 24 to 48 hours of application to activate the herbicide barrier in the top layer of soil. Without irrigation or rainfall to move the granules off plant material and into the soil surface, pre-emergent does not form an effective barrier and its effectiveness is dramatically reduced. We apply pre-emergent immediately before forecast rainfall when possible. When no rain is expected within 48 hours, we recommend running your irriga

Question 25

What Happens to Pre-Emergent Effectiveness After Aeration?

Accepted Answer

Core aeration disrupts the pre-emergent barrier by pulling holes through the chemical layer in the top inch of soil. Aerating after pre-emergent has been applied creates channels where weed seeds can germinate unimpeded. Ideally, time your spring aeration before the pre-emergent application: aerate in late March, then apply pre-emergent immediately after. If you aerate after pre-emergent was already applied, a targeted re-application of pre-emergent over the aeration holes is advisable for lawns

Question 26

What Causes Pre-Emergent to Fail Despite Correct Timing?

Accepted Answer

Even correctly timed pre-emergent applications can fail to prevent all weed germination due to several conditions specific to DFW. Heavy spring rainfall exceeding 2 inches within 7 days of application can leach granular pre-emergent below the germination zone before it forms an effective barrier. Disturbed soil areas from construction, utility work, or pet digging bypass the undisturbed surface barrier entirely. Mulched bed areas adjacent to turf have different soil chemistry and often require s

Question 27

When Does Post-Emergent Spot Treatment Outperform Blanket Applications?

Accepted Answer

Targeted treatment is safer for the lawn, uses less herbicide, and delivers better results than broad-scale application for most DFW weed situations.

Question 28

Why Is Selective Herbicide Matching Critical for St. Augustine Lawns?

Accepted Answer

Post-emergent herbicide selection in DFW is complicated by the fact that Bermuda and St. Augustine grass respond very differently to the same products. Several herbicides used routinely on Bermuda — including atrazine-based products and some broadleaf control formulations — cause severe injury or death to St. Augustine grass. This means the grass type must be confirmed before any post-emergent application. Properties with transitional zones where both grass types occur within close proximity req

Question 29

What Is the Best Way to Control Nutsedge After It Has Emerged?

Accepted Answer

Established nutsedge requires specialty post-emergent treatments using sedge-specific products such as halosulfuron (Sedgehammer) or sulfentrazone, which target the sedge family without harming Bermuda or most St. Augustine varieties. Application timing matters: nutsedge is most susceptible when plants are young and actively growing, typically 2 to 4 inches tall. Treating mature, seeding nutsedge is significantly less effective. Multiple applications spaced 4 to 6 weeks apart are necessary becau

Question 30

When Should You Use Spot Treatment versus Blanket Application?

Accepted Answer

Spot treatment — applying herbicide only to individual weed plants or distinct weed patches — is the correct approach when weed coverage is below 30 to 40 percent of the lawn area. Spot treatment uses significantly less herbicide, reduces cost, minimizes risk to turf from over-application, and is highly effective when weeds are accurately identified and treated with the correct product. Blanket application across the entire lawn is warranted when weed coverage exceeds 40 percent of the surface,

Question 31

How Long After Post-Emergent Treatment Should You Wait to Mow?

Accepted Answer

Most post-emergent herbicides require 24 to 48 hours of contact time on the weed foliage before mowing. Mowing immediately after application removes leaf surface before the herbicide has been absorbed and translocated to the root system, reducing effectiveness. For systemic herbicides targeting perennial weeds like dallisgrass or nutsedge, waiting 72 to 96 hours before mowing maximizes translocation to the root zone and improves control of the underground portions. Watering after treatment is ge

Question 32

Why Is Weed Control Most Effective as Part of a Comprehensive Program?

Accepted Answer

Herbicide applications alone — without addressing the underlying conditions that favor weed establishment — produce temporary results that require continual retreatment. Weed pressure decreases most durably when chemical control is paired with: correct mowing height that maintains turf density, annual core aeration to reduce compaction and improve root depth, consistent fertilization programs that build thick competitive turf, and proper irrigation management. A lawn receiving a complete agronom

Question 33

What Is the Re-Entry Interval After Herbicide Application?

Accepted Answer

The re-entry interval is the period after herbicide application during which treated areas should not be accessed by people or animals. For most granular pre-emergent products used in DFW lawn care, the re-entry interval is 24 hours or until the product has been watered in and the treated area has dried. Liquid post-emergent products typically require 1 to 2 hours of dry time before re-entry. We communicate re-entry intervals for every product applied and leave a treatment record with product na

Question 34
