Lawn Care Schedule for North Texas: A Complete Seasonal Guide

North Texas presents a unique set of challenges for homeowners who want a lush, green lawn. With scorching summers that routinely push past 100°F, unpredictable springs, and clay-heavy soil that compacts easily, maintaining healthy turf in the Dallas-Fort Worth metroplex and surrounding areas requires a strategic, season-by-season approach. Whether you are growing Bermuda grass, St. Augustine, Zoysia, or tall fescue, timing your lawn care tasks correctly is the single most important factor in achieving a thick, resilient lawn.

This comprehensive lawn care schedule for North Texas breaks down every essential task — from pre-emergent herbicide applications in late winter to core aeration in early summer — so you know exactly what to do and when to do it. Bookmark this guide and refer to it throughout the year to keep your lawn in peak condition no matter what the Texas weather throws your way.

Understanding the North Texas Lawn Care Calendar

North Texas falls primarily in USDA Hardiness Zones 7b through 8b, which means the region experiences hot, humid summers and relatively mild winters. Most lawns in the area are planted with warm-season grasses such as Bermuda, St. Augustine, Zoysia, or Buffalo grass. These grasses thrive when soil temperatures rise above 65°F in spring, go dormant and brown after the first hard frost in late fall, and green up again the following March or April.

A smaller number of homeowners — particularly those in the northern reaches of the metroplex and around the Red River — grow cool-season grasses like tall fescue. These grasses stay green through winter but struggle during the peak of summer heat. Your specific grass type will influence some details of the schedule below, so if you are unsure what you are growing, consult our grass identification guide before proceeding.

The North Texas lawn care year can be divided into five distinct phases: late winter preparation, spring green-up and growth, early summer maintenance, peak summer survival, and fall transition. Each phase has its own priorities, and getting the timing right prevents wasted money, damaged turf, and stubborn weed invasions.

Late Winter & Early Spring (February – March): Setting the Foundation

The work you do in late winter and early spring sets the tone for the entire growing season. Many homeowners in North Texas make the mistake of waiting until April to start thinking about their lawn, but the most critical tasks actually begin in February.

Apply Pre-Emergent Herbicide

The single most impactful thing you can do for your North Texas lawn in late winter is applying a pre-emergent herbicide. Crabgrass, dallisgrass, henbit, and annual bluegrass germinate when soil temperatures reach approximately 55°F for several consecutive days — which in North Texas typically happens between mid-February and early March. If you wait until you see weeds, it is already too late for a pre-emergent to work.

Recommended products: Prodiamine (brand names include Barricade) or dithiopyr (Dimension). Both provide long-lasting residual control. Apply at the label rate using a broadcast spreader and water in with approximately one-quarter inch of irrigation to activate the chemical barrier in the soil.

Timing tip: A reliable phenological indicator in North Texas is the blooming of forsythia bushes and Mexican plum trees. When you see these flowers opening, soil temperatures are approaching the germination threshold and it is time to spread your pre-emergent.

Soil Testing

Before you invest in fertilizers and amendments, get a soil test. Texas A&M AgriLife Extension offers affordable soil testing, and the results will tell you exactly what nutrients your lawn needs and whether your soil pH requires adjustment. North Texas soils are notoriously alkaline, with pH levels often between 7.5 and 8.5, which can lock up iron and cause chlorosis (yellowing) in turf. A soil test takes the guesswork out of your fertilization plan.

Sharp Mower Blades & Equipment Tune-Up

Use the late winter downtime to service your mower. Sharpen or replace the blades, change the oil, replace the air filter, and check the spark plug. Dull mower blades tear grass rather than cutting it cleanly, creating ragged tips that turn brown and invite disease. A sharp blade makes every mow throughout the season cleaner and healthier for your turf. For more details, see our lawn mower maintenance guide.

Spot-Treat Existing Weeds

Any cool-season weeds that survived the winter — such as henbit, chickweed, and clover — should be spot-treated with a post-emergent herbicide in late February or early March. Use a selective herbicide labeled for your specific grass type to avoid damaging the turf. For St. Augustine lawns, be especially careful with herbicides containing 2,4-D, as some formulations can injure this grass at higher rates.

Spring (April – May): Feeding, Growing, and Establishing

Once your warm-season grass breaks dormancy and begins greening up — usually by early to mid-April in North Texas — it is time to shift from preparation into active lawn care. This is the season of rapid growth, and your goal is to build a dense turf canopy that will crowd out weeds and withstand the brutal summer ahead.

First Fertilizer Application

Wait until your lawn has fully greened up and you have mowed it at least twice before applying fertilizer. Fertilizing too early feeds weeds and encourages lush, weak growth that is vulnerable to late-spring cold snaps. For most North Texas lawns, the ideal window for the first spring feeding is mid-to-late April.

Recommended products: A slow-release, nitrogen-rich fertilizer with a ratio such as 29-3-4 or 30-0-4 works well for warm-season grasses. Look for products that contain methylene urea or sulfur-coated urea for gradual nutrient release over eight to ten weeks. Avoid high-phosphorus fertilizers unless your soil test specifically indicates a deficiency.

Apply at the label rate using a rotary spreader for even coverage, and water the lawn lightly afterward to wash granules off the grass blades and into the soil.

Mowing Frequency & Height

Spring growth in North Texas can be explosive, especially after rain events. You may need to mow every five to seven days during peak spring growth. Follow the one-third rule: never remove more than one-third of the grass blade in a single mowing. Removing too much at once shocks the plant and exposes the soil to weed seeds and sunlight.

Ideal mowing heights for North Texas grasses in spring:

• Bermuda grass: 1 to 1.5 inches (common Bermuda) or 0.5 to 1 inch (hybrid Bermuda)
• St. Augustine: 2.5 to 3.5 inches
• Zoysia: 1 to 2 inches depending on variety
• Buffalo grass: 2 to 3 inches
• Tall fescue (cool-season): 3 to 4 inches

Irrigation Begins

North Texas springs can be generous with rainfall, but they can also be surprisingly dry. Begin supplementing with irrigation once weekly rainfall drops below one inch. The goal in spring is to encourage deep root growth by watering deeply and infrequently rather than giving the lawn a light sprinkle every day.

Run your sprinkler system long enough to deliver approximately one inch of water per application. You can measure this by placing empty tuna cans or rain gauges around your yard and timing how long it takes to fill them to the one-inch mark. For more on efficient watering, read our complete lawn watering guide.

Second Pre-Emergent Application

If you used prodiamine in February, a second application in late April or early May can extend your weed-free window through the summer. This is especially important for lawns with a history of crabgrass or dallisgrass pressure. Check the product label for the maximum annual application rate and do not exceed it.

Early Summer (June – Early July): Building Resilience

By June, North Texas lawns are in full growth mode and temperatures are climbing rapidly. This is the window for cultural practices that strengthen your turf before the most stressful part of the year arrives.

Core Aeration

North Texas is famous for its heavy clay soils, particularly the expansive blackland prairie clay found throughout the Dallas-Fort Worth area. This soil type compacts easily under foot traffic, mowing, and irrigation, creating a dense layer that restricts root growth, water infiltration, and nutrient uptake. Core aeration is the best remedy.

Rent a core aerator or hire a professional lawn service to pull small plugs of soil from your lawn. The ideal time for core aeration of warm-season grasses in North Texas is June, when the grass is actively growing and can recover quickly. Leave the soil cores on the lawn — they will break down naturally and return beneficial microorganisms to the thatch layer.

Tool recommendation: A walk-behind gas-powered core aerator from a local equipment rental shop works far better than the spike-type aerators or aerator shoes sold at garden centers. Spike aerators actually increase compaction around the holes rather than relieving it. For more on dealing with compacted soil, see our compacted soil guide.

Topdressing & Compost

Immediately after aeration is the perfect time to topdress your lawn with a thin layer (approximately one-quarter inch) of compost or a sand-compost blend. The material will fall into the aeration holes, improving soil structure, drainage, and microbial activity at the root zone. Screened compost with a fine texture works best — avoid anything with large chunks or high salt content.

Summer Fertilizer Application

A light application of slow-release nitrogen fertilizer in early June keeps warm-season grasses feeding steadily through the summer. Use a lower rate than your spring application — approximately 0.5 to 0.75 pounds of nitrogen per 1,000 square feet. Avoid fast-release nitrogen sources during peak summer heat, as they can burn the lawn if temperatures spike unexpectedly.

If your soil test indicated an iron deficiency (common in alkaline North Texas soils), a chelated iron supplement applied in June can correct yellowing without pushing excessive top growth.

Grub Prevention

White grubs — the larvae of June beetles and other scarab beetles — are a common problem in North Texas lawns. They feed on grass roots just below the soil surface and can cause large, irregular brown patches by late summer. Apply a preventive grub control product containing imidacloprid or chlorantraniliprole in June. These products need to be watered into the soil and will protect your lawn through the peak grub-feeding period in August and September.

Peak Summer (Mid-July – August): Survival Mode

This is the most stressful period for North Texas lawns. Daytime temperatures regularly exceed 95°F, rainfall becomes scarce, and water restrictions from local municipalities may limit irrigation days. Your primary goal during peak summer is keeping your lawn alive and minimizing stress — not pushing aggressive growth.

Adjust Mowing Height

Raise your mower deck by approximately half an inch during the hottest months. Taller grass shades the soil, reducing evaporation and keeping root zones cooler. For Bermuda grass, raise to 1.5 to 2 inches. For St. Augustine, raise to 3.5 to 4 inches. The extra leaf surface area also helps the plant photosynthesize more efficiently under heat stress.

Watering Strategy Under Restrictions

Most North Texas cities enforce twice-per-week watering schedules during summer. Make those sessions count by watering deeply in the early morning hours, ideally between 4 AM and 8 AM. Early morning watering minimizes evaporation losses and allows grass blades to dry before evening, which reduces the risk of fungal diseases like brown patch.

If your lawn shows signs of wilting — footprints that remain visible in the grass, a bluish-gray color, or folded leaf blades — it needs water immediately, even if it is not your scheduled irrigation day. Most municipalities allow hand-watering with a hose on off-days for spot treatment. Learn more about recognizing heat stress in our heat stress protection guide.

Avoid Fertilizer & Herbicides During Extreme Heat

Do not apply granular or liquid fertilizer when temperatures exceed 95°F. The salts in fertilizer can dehydrate grass roots and cause severe burn under extreme heat. Similarly, many post-emergent herbicides can volatilize and drift onto desirable plants when applied in high temperatures. If weeds are a problem during peak summer, hand-pull them or wait for a cooler window to spot-treat.

Watch for Chinch Bugs

Chinch bugs are a significant pest of St. Augustine grass in North Texas, particularly during hot, dry summers. They congregate at the edges of damaged areas and suck sap from grass stems, causing yellowing and browning that is often mistaken for drought stress. Part the grass at the border of a damaged area and look for tiny black insects with white wings. If you find more than 20 to 25 per square foot, treat with a labeled insecticide such as bifenthrin or carbaryl.

Fall (September – November): Recovery and Preparation

Fall is arguably the most underrated season for lawn care in North Texas. As temperatures moderate and warm-season grasses begin their slow transition toward dormancy, you have a window to repair summer damage, strengthen root systems, and prepare the lawn for a strong start the following spring.

Early Fall Fertilization

Apply a balanced, slow-release fertilizer in mid-September to help your lawn recover from summer stress and store energy in its root system before dormancy. A formulation such as 18-6-12 or a similar ratio with moderate potassium content is ideal — potassium strengthens cell walls and improves cold tolerance. This is sometimes called a "winterizer" application, though the term is somewhat misleading since the primary benefit comes in fall root development rather than winter protection.

For tall fescue and other cool-season grasses in North Texas, fall is the most important fertilization window of the entire year. Apply a heavier rate in September and a follow-up application in late October or early November for best results.

Overseeding Warm-Season Lawns with Ryegrass (Optional)

Some North Texas homeowners choose to overseed their dormant Bermuda or Zoysia lawns with annual or perennial ryegrass in October to maintain a green lawn through the winter. This is a personal preference — it requires additional mowing, watering, and fertilizing through the cool months, and the ryegrass must be managed carefully in spring so it does not compete with your warm-season grass as it greens up.

If you decide to overseed, mow the existing lawn slightly shorter than normal, spread ryegrass seed at 5 to 10 pounds per 1,000 square feet, and keep the seed consistently moist until germination occurs in seven to ten days. For those who prefer a low-maintenance approach, simply allow your warm-season lawn to go dormant and brown — it is perfectly healthy and will return in spring.

Fall Weed Control & Pre-Emergent

Apply a fall pre-emergent herbicide in late August or early September to prevent cool-season annual weeds such as annual bluegrass (Poa annua), henbit, and chickweed from germinating. This is just as important as the spring pre-emergent application, and many lawn care professionals in North Texas consider it the more impactful of the two.

Existing broadleaf weeds can be spot-treated with a post-emergent herbicide in September and October while temperatures are moderate and the herbicides can work effectively without heat-related turf injury.

Leaf Management

If your property has deciduous trees, fallen leaves can smother your lawn and block sunlight during a critical recovery period. Mulch leaves with your mower as they fall — a thin layer of finely chopped leaves adds organic matter to the soil. If leaf accumulation is heavy, rake or blow them off to prevent matting and fungal issues. For more tips, read our leaf management guide.

Final Mow and Winterization

Continue mowing as needed through October and early November until the grass stops growing. For the last mow of the season, lower the cutting height slightly — about half an inch below your normal height — to reduce the amount of leaf tissue that can harbor snow mold or other winter diseases. Drain and winterize your irrigation system before the first hard freeze, typically in late November or early December in North Texas, to prevent cracked pipes and damaged valves.

Recommended Tools & Products for North Texas Lawn Care

Having the right equipment on hand makes following this schedule far easier. Here is a consolidated list of the tools and products referenced throughout this guide:

• Broadcast/rotary spreader: Essential for even application of fertilizer, pre-emergent, and grass seed. A quality spreader with pneumatic tires and a hopper capacity of at least 50 pounds will last for years.
• Core aerator: Available for rent at most equipment rental stores in the Dallas-Fort Worth area. Plan to share the rental cost with a neighbor — one machine can aerate multiple lawns in a single day.
• Soil test kit: Available through Texas A&M AgriLife Extension or private labs. Test your soil at least once every two to three years.
• Pre-emergent herbicide: Prodiamine (Barricade) or dithiopyr (Dimension) for season-long weed prevention.
• Slow-release fertilizer: Choose a product formulated for warm-season grasses with at least 50 percent slow-release nitrogen.
• Rain gauge or soil moisture sensor: Takes the guesswork out of irrigation scheduling and helps you comply with local watering restrictions.
• Sharp mower blades: Keep a spare set on hand so you can rotate them and always have a sharp blade ready.
• Grub preventer: Products containing imidacloprid applied in June provide reliable protection through the grub season.

Frequently Asked Questions

When should I start mowing my North Texas lawn in spring?

Begin mowing when your warm-season grass has greened up and reached approximately one-third higher than your target mowing height. For most North Texas lawns, this happens in early to mid-April. Your first mow of the season — sometimes called a "scalp" for Bermuda grass — can be set slightly lower than normal to remove dead, brown material from winter dormancy and allow sunlight to warm the soil. Bag the clippings from this first mow to remove thatch debris. After the initial scalp, raise the deck to your normal height and begin a regular mowing schedule.

How often should I water my lawn during a North Texas summer?

During peak summer, aim to deliver one to one-and-a-half inches of water per week, split across two or three deep watering sessions. Most North Texas municipalities restrict irrigation to two days per week during summer, so plan your schedule accordingly. Water in the early morning hours between 4 AM and 8 AM to minimize evaporation and reduce disease risk. If you see wilting, footprints remaining in the grass, or a bluish-gray tint between scheduled watering days, supplement with hand-watering. Sandy soils may require more frequent watering, while heavy clay soils hold moisture longer and can go slightly longer between sessions.

What is the best grass type for North Texas?

The best grass for your North Texas lawn depends on your specific conditions. Bermuda grass is the most drought-tolerant and traffic-resistant option, making it ideal for full-sun lawns and active families. St. Augustine is the best choice for shady yards, as it tolerates more shade than any other warm-season grass commonly grown in the region. Zoysia offers a beautiful, dense turf with moderate shade tolerance and excellent weed resistance, though it establishes slowly and is more expensive to install. For cool-season options, tall fescue stays green through winter but requires significant irrigation during summer. Consult our best grass types for North Texas guide for a detailed comparison.

How do I fix brown patches in my North Texas lawn during summer?

Brown patches in summer can have several causes, and correct diagnosis is essential before treatment. The most common culprits include drought stress (the entire lawn turns dull and footprints remain visible), chinch bug damage (irregular patches at the edges of sunny areas, particularly in St. Augustine), grub damage (sod that lifts easily from the soil because roots have been eaten), and fungal diseases like brown patch or take-all root rot (circular or irregular patches with a distinct border). Inspect the affected area closely, check for insects at the soil line, tug on the grass to test root attachment, and consider sending a sample to the Texas A&M Plant Disease Diagnostic Laboratory if you suspect a fungal issue. Treatment varies dramatically depending on the cause, so accurate identification saves time and money.

Should I hire a professional lawn care service or do it myself?

This depends on your budget, available time, and comfort level with lawn care products. A do-it-yourself approach following the schedule in this guide can produce excellent results and typically costs between $500 and $1,000 per year for an average-sized North Texas lawn, including products and equipment rental. Professional lawn care services in the Dallas-Fort Worth area typically charge between $50 and $150 per visit for a standard-sized lawn, with most programs including six to eight visits per year. The advantage of professional service is access to commercial-grade products, calibrated equipment, and trained technicians who can identify problems early. If you choose the DIY route, start with our beginner's guide to lawn care to build your confidence before tackling advanced tasks like aeration and chemical weed control.

When is the best time to aerate a North Texas lawn?

The best time to core aerate warm-season grasses in North Texas is June through early July, when the grass is in its most vigorous growth phase and can recover rapidly from the procedure. Avoid aerating during peak summer heat in August, as the additional stress can weaken the lawn. For cool-season grasses like tall fescue, early fall (September) is the ideal aeration window, often combined with overseeding. Aeration should be performed at least once per year on lawns growing in heavy clay soil, which is prevalent throughout most of North Texas. Lawns with heavy foot traffic or those that receive regular equipment use may benefit from aeration twice per year.

By following this seasonal lawn care schedule, you can maintain a thick, healthy lawn that enhances your property and stands up to the unique challenges of the North Texas climate. Consistency and timing are everything — a small investment of effort at the right moment prevents far larger problems down the road.
