Cats Ear Weed Control Services
If you’ve spotted flat, hairy rosettes spreading across your lawn with yellow dandelion-like flowers sitting on tall, branching stems , you’re most likely dealing with Cat’s Ear weed. One of the most common and persistent broadleaf weeds found in Australian lawns, Cat’s Ear is frequently mistaken for dandelion, treated with the wrong products, and ends up worse than before. At Coochie HydroGreen, our professional weed control services are built to accurately identify, target, and eliminate Cat’s Ear , protecting your lawn and keeping it weed-free for the long term.
What Is Cats Ear Weed? How to Identify It in Your Lawn
Cat’s Ear (Hypochaeris radicata) is a perennial broadleaf weed native to Europe that has naturalised extensively across Australia. It thrives in lawns that are stressed, compacted, or under-nourished , making it both a symptom and a cause of a declining lawn. It’s found in all states and territories and is particularly prevalent in cooler-season and transitional climate regions.
Its common name comes from the shape and texture of its leaves , broad, lobed, and covered in soft hairs that resemble a cat’s ear.
Key Identification Features
- Flat rosette growth habit , leaves grow outward in a low, ground-hugging rosette that sits below mower height
- Hairy, lobed leaves , leaves are notably hairy on both surfaces, with irregular, rounded lobes along the edges
- Tall, branching flower stems , unlike dandelion, Cat’s Ear sends up multiple branching stems from a single rosette, each tipped with a yellow flower
- Hollow stems , stems are wiry, branched, and hollow when snapped
- Deep taproot , a thick, fleshy taproot anchors the plant firmly and drives regrowth after removal
- Milky sap , stems and leaves exude a milky white sap when broken
Cat's Ear vs. Dandelion , How to Tell the Difference
These two weeds are confused constantly , and treating one as the other leads to failed control. Here’s how to tell them apart:
Feature | Cat’s Ear (Hypochaeris radicata) | Dandelion (Taraxacum officinale) |
Leaf texture | Hairy on both sides | Smooth or slightly hairy |
Leaf shape | Broad lobes, irregular edges | Deep, sharply toothed lobes |
Flower stem | Tall, branching, multiple flowers | Single hollow stem, one flower |
Stem when broken | Branched, wiry, hollow | Single, straight, hollow |
Seed head | Smaller, irregular puffball | Classic large, round puffball |
Taproot | Thick and fleshy | Long and slender |
Growth habit | Dense, spreading rosette | Upright rosette |
Getting this identification right matters , herbicide selection differs between the two. A Coochie HydroGreen technician will confirm exactly what you’re dealing with before any treatment begins.
This is an important question , particularly for horse owners and families with grazing animals.
Cat’s Ear (Hypochaeris radicata) has been strongly linked to Australian Stringhalt, a neurological condition in horses characterised by exaggerated, involuntary hind leg movement. While the exact mechanism is still being researched, outbreaks of Stringhalt in Australia are consistently associated with horses grazing on pastures heavily infested with Cat’s Ear, particularly during dry conditions when other feed is scarce.
For dogs and cats, Cat’s Ear is not considered significantly toxic, though large quantities consumed may cause mild digestive upset. The primary concern for family pets is more about the overall lawn environment , a weed-dense lawn often indicates reduced turf health, which is worth addressing regardless.
If you have horses on your property or nearby grazing land, prompt Cat’s Ear weed control is strongly recommended. Contact Coochie HydroGreen to arrange an assessment as soon as possible.

Why Does Cat's Ear Keep Coming Back?
This is the question most homeowners ask after trying to deal with Cat’s Ear themselves , and the answer comes down to the biology of the plant and the limitations of common DIY approaches.
Mowing wont eliminate it. Cat’s Ear rosettes grow flat to the ground, sitting below the height of most mower blades. Mowing doesn’t remove the plant , it just removes the flower heads before they can set seed. The rosette and taproot remain completely intact and continue growing.
Hand-pulling is unreliable. The deep, fleshy taproot breaks easily when pulled, leaving the lower portion in the soil. Any remaining root fragment can regenerate a new plant. Unless the entire taproot is removed , which requires the right tools and technique , hand-pulling provides only temporary relief.
Â
It thrives in stressed lawns. Cat’s Ear is an opportunist. It establishes most readily in compacted soil, thin turf, low-fertility areas, and drought-stressed lawns. If the underlying lawn health isn’t addressed alongside the weed treatment, new plants will continue to germinate into the same weak spots.
Prolific seeding. A single Cat’s Ear plant can produce hundreds of wind-dispersed seeds per season. Each seed is attached to a feathery pappus that carries it considerable distances , meaning even a well-treated lawn can be reinfected from neighbouring properties or nature strips.
Wrong herbicide selection. Many off-the-shelf broadleaf herbicides can be inconsistent in the results on Cat’s Ear, particularly on established plants with large taproots. Without the right product, rate, and timing, treatment results are inconsistent at best.

Our approach to Cat’s Ear control is thorough, tailored, and backed by our service warranty , the same professional process we apply across all of our weed control services.

Tailored treatment plan , We select the appropriate commercially registered broadleaf herbicide, applied at the correct rate and timing for your specific lawn conditions. Established plants with large taproots may require repeat applications for complete control.
Follow-up monitoring , Because Cat’s Ear seeds remain viable in the soil for several years, follow-up visits are essential to catch new germination before it re-establishes. If you’re on our Lawn Care Programme, your technician will monitor and treat as part of your regular service at no extra cost.
Lawn health support , Cat’s Ear thrives in weak, compacted, and underfed lawns. As part of our broader lawn care maintenance service, we help strengthen your turf through seasonal fertilisation, soil conditioning, and moisture management , making it far more resistant to weed re-establishment over time.
Our licensed, insured technicians service over 140 regions across Australia , from major cities to regional areas , so professional Cat’s Ear control is closer than you think.
Frequently Asked Questions About Cat's Ear Weed
What is Cat's Ear weed and why is it so common in Australian lawns?
Cat’s Ear (Hypochaeris radicata) is a perennial broadleaf weed that has naturalised widely across Australia. It thrives in compacted, underfed, or drought-stressed lawns where desirable turf is thin and struggling. Its ability to regenerate from a deep taproot and spread via wind-carried seeds makes it one of the most persistent and widespread lawn weeds in the country.
Is Cat's Ear the same as dandelion?
No, though they look similar at a glance. The key differences are that Cat’s Ear has hairy leaves and branching flower stems with multiple flowers, while dandelion has smooth leaves and a single flower per stem. This distinction matters for treatment, as the two weeds respond differently to herbicides. Professional identification before treatment saves time, money, and prevents lawn damage.
Why does Cat's Ear keep coming back after I mow it?
Mowing has no effect on Cat’s Ear because the plant’s rosette sits below mower height. The taproot and growing crown remain completely untouched. Even removing the flower heads before seed set doesn’t stop the plant from regenerating and eventually flowering again. Effective control requires a registered herbicide that targets the plant systemically, including the taproot.
Can I pull Cat's Ear out by hand?
Hand-pulling provides only temporary relief. Cat’s Ear has a thick, fleshy taproot that breaks easily during removal, leaving the lower root in the soil to regenerate. For small, isolated plants in loose soil, careful removal with a weeding tool can work , but for established infestations, professional herbicide treatment is far more effective and reliable.
Is Cat's Ear harmful to horses?
Yes , Cat’s Ear has been strongly linked to Australian Stringhalt, a serious neurological condition in horses. Outbreaks consistently occur in horses grazing on pastures heavily infested with Cat’s Ear, particularly during dry periods. If you have horses on your property or nearby, prompt professional weed control is strongly recommended. Contact Coochie HydroGreen to arrange an urgent assessment.
