Crabgrass vs Goosegrass: How to Tell the Difference and How To Get Rid of Them

If you’ve got a low-growing grassy weed spreading across your lawn, most people immediately assume it’s crabgrass.

But there’s a crabgrass lookalike that may actually be the weed ruining your lawn’s aesthetic: goosegrass.

These two weeds look similar at first glance. They both grow low to the ground, spread outward, and show up when temperatures heat up. But crabgrass and goosegrass behave very differently, and using the wrong weed control strategy can waste an entire season.

In this guide, we’ll break down:

• What crabgrass looks like

• How to identify goosegrass

• The key differences between crabgrass vs goosegrass

• The best crabgrass killer and goosegrass control options

Need the quick answer?

• Crabgrass spreads outward in a loose, star-shaped pattern.

• Goosegrass grows in a tight rosette with a distinctive white or silver center.

• Crabgrass leaves are wider and lighter green.

• Goosegrass leaves are narrower and darker.

• Both weeds thrive in thin, stressed lawns and hot weather.

• Pre-emergent herbicides can prevent both, but timing is critical.

If your weed has a flat wagon-wheel shape with a white center, it’s probably goosegrass, not crabgrass.

Why Crabgrass and Goosegrass Get Confused

These two weeds show up at roughly the same time — late spring through summer — and both grow low to the ground.

They also tend to invade the same lawn conditions:

• Thin turf

• Compacted soil

• Bare patches

• Areas that get heavy foot traffic

Because of these similarities, many homeowners lump them together as just “crabgrass.” But knowing the difference makes weed control much easier.

What Does Crabgrass Look Like?

Crabgrass is one of the most common summer weeds in lawns across the United States. Botanically, it belongs to the Digitaria genus, most commonly Digitaria sanguinalis (large crabgrass) and Digitaria ischaemum (smooth crabgrass).

It’s a summer annual weed, which means it germinates from seed in spring, grows aggressively through the heat of summer, then dies after the first frost. The problem is that before it dies, it produces thousands of seeds, setting the stage for the next year’s invasion.

Because of its spreading growth habit, crabgrass often appears as low, sprawling patches that creep outward across the lawn.

Other Common Names for Crabgrass

Depending on the region, crabgrass may also be called:

• Finger grass

• Summer grass

• Crowfoot grass (sometimes shared with goosegrass)

• Crab grass (two words).

Most lawn guides simply refer to it as crabgrass, but the two main species found in lawns behave very similarly.

Crabgrass Identification

Here’s what to look for when identifying crabgrass.

Growth pattern:
Crabgrass spreads outward from a central crown in a loose, star-like shape, with stems that radiate along the ground.

Leaf color:
Usually light green or yellow-green, often noticeably lighter than surrounding turfgrass.

Leaf texture:
Leaves are wide, coarse, and slightly hairy, especially near the base of the leaf blade.

Height:
Crabgrass typically grows low and spreading, though mature plants can reach several inches tall.

Roots:
Crabgrass has shallow roots and spreads by sending out stems (called tillers) that root where they touch the soil.

Seed heads:
Later in summer, crabgrass produces finger-like seed heads that extend from a central point.

Where Crabgrass Appears

Crabgrass is an opportunistic weed, meaning it takes advantage of weak or thin turf.

It commonly appears in:

• Bare patches in lawns

• Thin or stressed turf

• Along sidewalks and driveways

• Areas that warm up quickly in spring

• Lawns mowed too short.

Young Crabgrass

Young crabgrass often starts as a small tuft of grass that rapidly spreads outward across the soil surface. At this early stage, the plant is easier to control, which is why early treatment with a crabgrass killer works best.

What Does Goosegrass Look Like?

Goosegrass is another common summer annual weed that shows up in lawns across much of the United States. Its scientific name is Eleusine indica, and it’s part of the same grass family as crabgrass but belongs to a completely different genus.

Like crabgrass, goosegrass germinates in late spring and thrives in hot weather, but it tends to appear slightly later in the season and prefers compacted soil conditions.

At a glance, goosegrass can resemble crabgrass. However, once you know the key characteristics, goosegrass identification becomes much easier.

Other Common Names for Goosegrass

Goosegrass goes by several other names, including:

• Silver crabgrass

• Crowfoot grass

• Wiregrass

• Yard grass

• Indian goosegrass.

The nickname silver crabgrass comes from one of its most recognizable features: the pale center at the base of the plant.

Goosegrass Identification

Here’s how to spot goosegrass in your lawn.

Growth pattern:
Goosegrass forms a tight rosette or wagon-wheel pattern, with stems growing outward in a flattened circle.

White center:
The base of the plant often has a distinct white or silvery center, which is one of the easiest ways to tell it apart from crabgrass.

Leaf blades:
Leaves are narrower and darker green than crabgrass leaves.

Texture:
Goosegrass leaves are typically smooth and flattened, without the hairiness often seen on crabgrass.

Roots:
Goosegrass develops a tough central crown and fibrous root system, allowing it to tolerate heavy traffic and compacted soil.

Seed heads:
Mature goosegrass produces several finger-like seed spikes that extend from the top of the plant.

Where Goosegrass Appears

Goosegrass thrives in hard, compacted soil where turfgrass struggles to grow.

You’ll often find it in:

• Driveway edges

• Walkways and paths

• High-traffic lawn areas

• Sports fields

• Compact soil zones in the yard.

While crabgrass tends to invade thin lawns, goosegrass is more likely to show up where soil compaction limits turf growth.

Early Goosegrass Growth

Young goosegrass plants start as small rosettes close to the ground. As they mature, they form dense, flattened clumps that can tolerate heavy traffic and extreme summer heat.

Because goosegrass becomes tougher as it matures, early identification and treatment are important for effective control.

Crabgrass vs Goosegrass: Key Differences

Here’s a simple side-by-side comparison.

Feature	Crabgrass	Goosegrass
Growth shape	Loose spreading	Tight wagon wheel
Center color	Green	White or silver
Leaf width	Wide	Narrow
Leaf color	Light green	Darker green
Soil preference	Thin turf	Compacted soil

The white center is the quickest visual clue that you’re dealing with goosegrass.

Crabgrass vs Goosegrass Seed Heads

One of the easiest ways to confirm identification later in the season is by looking at the seed heads.

Crabgrass seed heads

• Several thin spikes that spread outward from a central point

• Often described as looking like fingers on a hand.

Goosegrass seed heads

• Multiple spikes arranged along a single upright stem

• Often resemble a crow’s foot or zipper pattern.

Once these seed heads appear, both weeds are already mature and may have begun dropping seeds.

Why Crabgrass and Goosegrass Take Over Lawns

Crabgrass and goosegrass are opportunistic weeds.

They don’t usually invade healthy turf. Instead, they take advantage of lawns that are struggling. Common conditions that invite crabgrass and goosegrass include:

• Compacted soil

• Low mowing height

• Thin grass coverage

• Poor fertility

• Drought stress

A dense lawn is your best defense against both weeds.

When Do Crabgrass and Goosegrass Germinate?

Crabgrass and goosegrass germinate at slightly different soil temperatures, which affects herbicide timing.

• Crabgrass begins germinating when soil temperatures reach about 55°F for several days.
  

• Goosegrass usually germinates later, when soil temperatures reach 60–65°F.

This is why a properly timed pre-emergent herbicide application in spring is critical for preventing both weeds.

How to Kill Crabgrass

Crabgrass control is all about timing and prevention. Because crabgrass grows from seed every year, stopping it early is the most effective strategy.

Step 1: Use a Pre-Emergent Herbicide

Pre-emergent herbicides prevent crabgrass seeds from germinating. They create a barrier in the soil that stops seedlings before they can establish.

For best results, apply a pre-emergent when soil temperatures reach about 55°F in spring, which is typically when forsythia bushes begin to bloom in many regions.

Proper application is important. The herbicide barrier needs to remain intact, so avoid disturbing the soil after applying it. Watering the product in lightly helps activate it and move it into the upper soil layer where weed seeds germinate.

Step 2: Treat Existing Crabgrass

If crabgrass is already growing, you’ll need a post-emergent crabgrass killer.

These herbicides target grassy weeds while leaving established turfgrass unharmed. The key is to treat the weed while it is still young and actively growing. Small crabgrass plants are much easier to control than mature ones.

Once crabgrass begins producing seed heads, control becomes more difficult and the plant may have already released seeds that will germinate next season.

How to Get Rid of Goosegrass

Goosegrass control works similarly to crabgrass control, but it can be a little trickier. This weed tolerates heat, compacted soil, and heavy traffic, which allows it to survive in places where turfgrass struggles.

Step 1: Prevent Germination

Pre-emergent herbicides can prevent goosegrass, but timing is important. Goosegrass typically germinates slightly later than crabgrass, when soil temperatures reach about 60–65°F.

Step 2: Use Post-Emergent Control

Once goosegrass appears, selective herbicides designed for grassy weeds are the most effective control option. Because goosegrass plants grow in dense clumps and develop tough crowns, multiple applications may sometimes be necessary for full control.

Step 3: Reduce Soil Compaction

Because goosegrass thrives in hard, compacted soil, improving soil conditions can make a big difference in long-term control.

Aerating compacted areas allows air, water, and nutrients to reach the roots of turfgrass, helping it grow thicker and compete more effectively against weeds.

Recommended Herbicides for Crabgrass and Goosegrass Control

Crabgrass (L) Goosegrass (R)

 

The most important thing to understand about crabgrass and goosegrass control is that prevention is usually easier than cure. Goosegrass in particular can be stubborn once it’s mature, so a strong pre-emergent program is often the best strategy.

Here are some of the most effective herbicides available at Golf Course Lawn and how they fit into a smart weed control plan.

Pre-Emergent Herbicides (Best for Prevention)

If you want to stop crabgrass and goosegrass before they even start, pre-emergent herbicides are the gold standard. These products create a barrier in the soil that prevents weed seeds from germinating.

One of the most powerful options available is Specticle® FLO Pre-Emergent Herbicide, a professional-grade pre-emergent that provides long-lasting control of many annual grassy weeds, including crabgrass and goosegrass. It’s often used by turf professionals when they want season-long prevention with fewer applications.

 

specticle-flo-pre-emergent-herbicide

 

Another popular choice is Prodiamine 65 WDG (Brand Alternative Barricade® 65WDG), one of the most widely used pre-emergent herbicides in lawn care. Prodiamine creates a durable barrier in the soil that prevents crabgrass and goosegrass seeds from establishing in the first place.

 

prodiamine-65-wdg-brand-alternative-barricade%C2%AE-65wdg

 

For homeowners who prefer a granular option that also feeds the lawn, Dimension .15% Pre-Emergent Herbicide with Fertilizer 0-0-7 combines fertilizer with a pre-emergent herbicide to block weeds while helping turfgrass green up in spring.

 

dimension-15-pre-emergent-herbicide-with-fertilizer-0-0-7

 

Timing matters with pre-emergents. Apply them when soil temperatures reach about 50–55°F in spring, before summer annual weeds begin germinating.

Post-Emergent Options for Goosegrass

Once goosegrass appears, control becomes more limited depending on your turfgrass type.

For cool-season lawns and certain warm-season grasses, Tenacity Herbicide can suppress or control young goosegrass plants. Tenacity is labeled for cool-season turf and also for Buffalograss, Centipedegrass, and St. Augustinegrass, making it a versatile option for some lawns.

 

tenacity-herbicide

 

Another option is Fusilade II Herbicide, which controls crabgrass and goosegrass in Zoysiagrass, Tall fescue, and Fine fescue lawns. This product targets grassy weeds selectively while leaving labeled turf species unharmed.

 

fusilade-ii-herbicide-annual-and-grassy-weed-control

 

For Bermuda lawns, your best bet is a herbicide with the active ingredient Foramsulfuron, such as Revolver. This can also combat crabgrass. 

Because goosegrass becomes harder to kill as it matures, early treatment is key.

Post-Emergent Crabgrass Killers

If crabgrass has already appeared, targeted post-emergent herbicides can eliminate it while leaving turfgrass intact.

Two reliable options include Quintessential Herbicide and Drive XLR8 Herbicide. Both products contain quinclorac, a widely used active ingredient for controlling crabgrass in established lawns.

These herbicides are most effective when applied to young crabgrass plants before they mature and produce seed heads.

The Best Defense Against Crabgrass and Goosegrass: A Thick, Healthy Lawn

When it comes to crabgrass and goosegrass control, prevention is always easier than cure. Goosegrass in particular can be stubborn once it’s established, which is why most successful lawn care programs focus on stopping these weeds before they germinate and maintaining strong turf that crowds them out.

Pre-emergent herbicides play a big role in this strategy. Applied in early spring, they create a barrier in the soil that prevents weed seeds from sprouting. If a few weeds still sneak through, treating them early while they’re small gives you the best chance of successful control.

But herbicides are only part of the equation. The real long-term solution is a thick, healthy lawn. When turfgrass is dense and vigorous, weeds struggle to find the space and sunlight they need to grow.

To keep your lawn competitive against weeds, focus on the fundamentals:

• Apply pre-emergent herbicides in early spring

• Spot treat weeds early if they appear

• Maintain the correct mowing height

• Follow a consistent fertilization program

• Aerate compacted soil, especially in high-traffic areas

• Improve overall soil health.

When your lawn is healthy and full, weeds like crabgrass and goosegrass have a much harder time gaining a foothold.

FAQs: Goosegrass vs Crabgrass

Is goosegrass harder to kill than crabgrass?

Yes, goosegrass is often harder to control once it becomes established. Crabgrass spreads aggressively but usually responds well to post-emergent herbicides. Goosegrass, on the other hand, tolerates heat, heavy traffic, and compacted soil, which can make it more stubborn to eliminate.

When do crabgrass and goosegrass germinate?

Crabgrass typically germinates when soil temperatures reach about 55°F for several consecutive days, which is usually early to mid-spring. Goosegrass usually germinates a little later, when soil temperatures reach around 60–65°F. This timing difference is one reason pre-emergent herbicide applications sometimes miss goosegrass if applied too early.

Can crabgrass or goosegrass survive the winter?

No. Both crabgrass and goosegrass are summer annual weeds, which means the plants die after the first hard frost. However, each plant can produce thousands of seeds before dying, allowing the weeds to return the following year if those seeds germinate.

Does mowing help control crabgrass or goosegrass?

Proper mowing can reduce weed pressure but won’t eliminate established weeds. Maintaining the correct mowing height for your turfgrass helps shade the soil surface and prevent weed seeds from germinating. Scalping the lawn, on the other hand, creates ideal conditions for both crabgrass and goosegrass to invade.

Can crabgrass or goosegrass grow in healthy lawns?

They can, but they are much less likely to establish in thick turf. These weeds usually appear where turfgrass is weak or stressed, such as bare patches, compacted soil, or areas with poor fertility.

How many seeds can crabgrass or goosegrass produce?

A single crabgrass plant can produce thousands of seeds during one growing season, which is why infestations can spread so quickly if left untreated. Goosegrass also produces a large number of seeds, allowing it to reappear year after year if preventive measures are not used.

Will watering affect crabgrass or goosegrass growth?

Yes. Frequent shallow watering can encourage weed seed germination near the soil surface. Watering deeply but less often encourages deeper turf roots and helps strengthen the lawn, making it more competitive against weeds.

Can crabgrass and goosegrass grow together?

Yes. It’s actually very common to find crabgrass and goosegrass growing in the same lawn, especially in areas where turf is thin, stressed, or damaged. Both weeds are summer annual grasses that germinate in warm soil, so their growing seasons often overlap.

However, they tend to dominate slightly different problem areas within the same yard. Crabgrass usually appears in bare or thinning turf, where sunlight easily reaches the soil surface and seeds can germinate. Goosegrass, on the other hand, thrives in compacted soil and high-traffic zones, such as along sidewalks, near driveways, or in areas where people and pets frequently walk.

Because of this, you might see crabgrass spreading across open patches of lawn while goosegrass forms tight clumps in compacted spots nearby. When both conditions exist in a yard — thin grass and compacted soil — it’s not unusual for homeowners to battle both weeds at the same time.

Crabgrass vs Goosegrass: Keep the Crabs at the Beach and the Geese at the Lake

Crabgrass and goosegrass may look similar at first glance, but knowing the difference makes it much easier to choose the right control strategy.

The simplest visual clue is their growth pattern. Crabgrass spreads outward in a loose, star-like shape, while goosegrass forms a tighter wagon-wheel pattern with a distinctive white or silvery center at the base of the plant.

Once you identify the weed correctly, you can choose the right treatment approach — whether that means applying a targeted post-emergent herbicide or focusing on prevention with a well-timed pre-emergent application.

But remember, herbicides are only part of the solution. A thick, healthy lawn is still the best long-term defense against weeds. When turfgrass is dense and well maintained, weeds like crabgrass and goosegrass have far fewer opportunities to take hold.

If crabgrass or goosegrass is invading your lawn, the right products make all the difference. Explore our lineup of professional-grade crabgrass killers, pre-emergent herbicides, and lawn care solutions designed to keep your turf thick, healthy, and weed-free all season long.
