Common Lawn Weeds and How To Identify Them | A Comprehensive Guide

Simply put, weeds are plants that grow in places where you do not want them to grow. Even the most maintained and heavily cared lawns are not safe from weeds. Weeds come in many forms, shapes and sizes. They grow aggressively and often produce a large number of seeds and spores, further assisting their spread. Read our lawn weed identification guide below.

Photo Credit Eliminating weeds requires proper knowledge of the weed you are dealing with and how it spreads.

Where some weeds only ruin the aesthetics of your lawn, others can compete aggressively with plants and grass in your yard. As a result, the grass in your yard has less space, water, nutrients and other essential resources available for healthy growth.

That is why experts suggest always keeping an eye out for weeds on your lawn. However, sometimes people do not even realize that they have weeds growing on their lawn until it is too late. It is because they do not know what weeds look like.

Moreover, even though weed control is not rocket science, you still need to understand the weed you are dealing with, how it grows, and the best way to control its spread. Only then will you be able to eliminate a weed from your lawn.

So, let’s go ahead and learn about some common lawn weeds, what they look like and what you can do to eliminate weeds from your lawn efficiently.

Types Of Weeds

Before we start talking about common lawn weeds, it is crucial to know how weeds are classified and on what basis. It will help you understand weeds better and equip you better at dealing with and getting rid of common lawn weeds. 

Annual Weeds

Annual Weeds

Annual weeds are plants that complete their life cycle within one year. In other words, annual weeds sprout, grow, flower and set seeds in a single year. However, it is essential to note that some weeds can do this within a few weeks.

It means that annual weeds can sometimes have multiple generations in a single year. Common examples of annual weeds include crabgrass, goosegrass, chickweed, knotweed, pigweed, nettle and hairy bittercress.

Biennial Weeds

Biennial weeds are plant pests that complete their life cycle in two years. Biennial weeds grow during the first year; however, they remain in a vegetative state and rarely set seeds. Whereas, in the second year, a biennial weed will flower, set seed and then die.

Some sources also use the word two seasons instead of two years. Common biennial weeds include bull thistle, garlic mustard, blueweed, wild parsnip, small flower buttercup and yellow salsify.

Perennial Weeds

Perennial weeds are plants that appear regeneratively time and again, year after year, a seemingly infinite number of times. Perennial weeds live more than two years, and they are very hard to get rid of.

Examples of common perennial weeds include nutsedge, field bindweed, dandelion, oxalis, white clover, creeping charlie and Canada thistle.

In addition to being classified based on their life cycles, weeds are generally put into two groups based on their morphology. These groups are:

Grassy Weeds

As the name implies, grassy weeds look like grass. Unfortunately, these weeds are hard to identify. Most people do not even notice their presence until it is too late. Common examples of grass weeds are crabgrass, creeping bentgrass, and sedges.

Broadleaf Weeds

Broadleaf Weeds

Photo Credit Ground ivy: An evergreen broadleaf weed that spreads aggressively via runners on the ground.

Broadleaf weeds are usually easy to locate and identify as they stick out in the grass. Most broadleaf weeds have leaves with netlike veins. Common examples of broadleaf weeds include chickweed, clover, thistle and ground ivy.

In addition to their life cycle and morphology, weeds are also put into different groups based on their ecological effects. These groups are:

Noxious Weeds

As the name suggests, noxious weeds are those plant pests that are considered to be harmful to humans, animals and the environment. Sometimes these weeds are also subject to regulations by an agricultural or government authority to control their spread.

Invasive Weeds

Invasive weeds are non-native plant species that have a tendency to grow uncontrollably due to a lack of natural competitors. Just like a noxious weed, an invasive weed can also cause severe damage to environmental health.

Noxious and invasive weeds vary from place to place. To check out the list of weeds declared noxious/invasive in your state, check out the USDA database here.

Common Lawn Weeds

Now that you understand how weeds are classified based on their life cycle, morphology and environmental effects, let’s move on towards learning about some of the most common lawn and garden weeds. We will provide you with a detailed overview of the weed, along with an identification guide and top control methods. So, let’s dive right in:

Common Dandelion

Common Dandelion

Photo Credit Common dandelion germinates and flowers year-round but mainly in fall and spring.

Dandelion is a common weed of lawns, gardens, ornamental beds, nurseries and other turf areas. Dandelions have a deep taproot, which makes removing established plants rather tricky. They spread by seeds that can be produced even without pollination.

You can simply pull out dandelions to control their spread at the start of an infestation. However, make sure that you remove the entire root, or the weed will grow back. In later stages of infestation, use a broadleaf herbicide to kill the dandelions on your lawn.

Common Dandelion Quick Facts & Identification

Scientific nameTaraxacum officinale
Other namesClock, Blowball
Weed typeBroadleaf Perennial
Height5 to 45 cm
IdentificationLeaves
– Leaves are lance-shapes and irregularly lobed
– Leaves grow in a rosetteLeaves are often purple at the base
Flowers
– Flowers are borne in heads that form round balls
– Flowers are deep golden yellow
– Flower stalks emit a milky white sap when broken

Canada Thistle

Canada Thistle - lawn weed identification

Photo Credit Canada thistle was the first weed declared noxious in the United States.

Like common dandelion, canada thistle also produces a robust root system that continuously gives rise to new shoots. This allows the need to invade new areas, and it often outcompetes other vegetation in the area.

You can control the spread of Canada thistle by mowing the grass before the weed has set seeds. The application of foliar herbicides is also helpful during fall and spring. However, you will need to monitor the lawn for several seasons post initial treatment.

Canada Thistle Quick Facts & Identification

Scientific nameCirsium arvense (L.) Scop.
Other namesCreeping thistle, Field thistle, Californian thistle
Weed typeBroadleaf Perennial
Height2 to 5 feet 
IdentificationLeaves
– Leaves have toothed margins and sharp spines
– Leaves are alternate and lance-shaped
– Leaves are shiny and have a deep green color
Flowers
– Flowers are born in clusters
– Flowers are pink, purple and occasionally white
– Canada thistle flowers from June to late autumn

Creeping Buttercup

Creeping Buttercup

Photo Credit Creeping buttercup has low seed production and mainly spreads by above-ground runners.

Creeping buttercup is known for its bright yellow flowers that attract many pollinating insects. However, do not be fooled by its looks! Creeping buttercup is a common weed of lawns, gardens and bare soil areas where it can form dense mats.

If you have a creeping buttercup infestation, at first, try suppressing the weeds with mulch or by digging up the individual plants. However, if these methods are not feasible, you can use herbicides containing MCPA (many trade names) or Aminopyralid.

Creeping Buttercup Quick Facts & Identification

Scientific nameRanunculus repens
Other namesCreeping crowfoot, Sitfast
Weed typeBroadleaf Perennial
Height50 cm (20 in) 
IdentificationLeaves
– Leaves are triangular with three deeply cut lobes

Flowers
– Creeping buttercup flowers mainly between May and August
– Flowers are bright yellow and glossy
– Flowers have five and occasionally, ten petals

Bindweed

Bindweed - lawn weed identification

Photo Credit Bindweed has a deep root system, reaching 20 to 30 feet deep.

If you know someone who has dealt with bindweed, they can tell you how frustrating and infuriating these weeds can be. Bindweed can be seen vining along the surface of lawns and gardens. It often also makes its way up your favorite plants or lawn fences and hedges by winding all around them, which no one likes.

Bindweed is not a weed that you can control using your hands. Therefore, chemical control methods are often the only choice. Herbicides containing 2, 4-D, MCPP and dicamba have proven to be very effective in controlling bindweed.

Bindweed Quick Facts & Identification

Scientific nameConvolvulus arvensis
Other namesMorning glory
Weed typeBroadleaf Annual or Perennial
Height0.4 to  2 inches
IdentificationLeaves
– Bindweed has heart-shaped leaves

Crabgrass is one of the most troublesome weeds on home lawns, gardens and other turf areas. It has a prolific branching or tillering habit. It reproduces by seeds which are produced in colossal numbers by the grass.

At the start of infestation, when the plants are young and have not set seeds, you can easily control their spread by mulching, hoeing, and hand pulling. However, actively growing crabgrass needs to be controlled with post-emergence herbicides.

You can also use pre-emergent herbicides to avoid getting a crabgrass infestation.

Crabgrass Quick Facts & Identification

Scientific nameGenus Digitaria
Other namesFinger grass, Fonio
Weed typeGrassy Annual
HeightAbout 6 inches
IdentificationLeaves
– Crabgrass leaves are broad and flat
– Leaves are usually lime green in color

Photo Credit Herbicides containing fluroxypyr, triclopyr or quinclorac provide the best control against white clovers.

White clover is a low-growing, creeping weed with a very vigorous growth habit. It often grows in patches alongside roads and in lawns and pastures. These weeds especially grow in such yards where competition from the grass is low. Therefore, the best control against a white clover infestation is to maintain a healthy and thick lawn. 

However, large infestations or large patches of white clover are hard to get rid of and need a chemical control. The best time to apply herbicide treatment for white clover control is early fall.

White Clover Quick Facts & Identification

Scientific nameTrifolium repens
Other namesDutch clover, Ladino clover, Ladino
Weed typeBroadleaf Perennial
Height6 to 12 inches 
IdentificationLeaves
– Leaves are alternate, stalkless and compound

Pokeweed

Pokeweed

Photo Credit Pokeweed berries are incredibly messy and can cause irritation on the touch.

Pokeweed is a typical urban and landscape weed with a poisonous root resembling that of horseradish. It often outcompetes local vegetation, and its berries are incredibly messy and hazardous. In addition, pokeweed spreads via seed, and it often spreads very quickly in areas with high bird activity.

Pulling the weed is not a suitable control method as pokeweed has deep roots which can regrow into new plants. Chemical herbicides containing 2,4-D and glyphosate provide the best results when used on young plants.

Pokeweed Quick Facts & Identification

Poison Ivy

Poison ivy - lawn weed identification

Photo Credit Poison ivy is a noxious weed that can cause a severe rash on the touch.

Poison ivy is a noxious weed that is native to Minnesota. It can be very tricky to identify. Poison ivy exhibits an array of leaf shapes, colors and growth habits. It can creep near the surface of the soil, exist as a shrub and climb like a woody vine.

Physical control methods usually do not result in any satisfactory results. Therefore, chemical control is the only good defense against poison ivy. However, even herbicides have to be applied several times before poison ivy can be eradicated entirely. 

Herbicides that contain dicamba, mecoprop and 2,4-D amine often produce the best results against poison ivy.

Poison Ivy Quick Facts & Identification

Scientific nameToxicodendron radicans
Other names
Weed typeBroadleaf Perennial
HeightShrub: 1 to 2 feet, Climbing: 3 to 12 feet
IdentificationLeaves

Chickweed

Chickweed

Photo Credit Chickweed creates lush green dense mats with small white flowers on the ground.

Common chickweed is a significant problem in nutrient-rich soils, especially soils that are rich in nitrogen. Moreover, it frequently invades lawns and places that are well-watered; however, it can also survive drier conditions. It is also used as an indicator of soil fertility.

The best way to get rid of chickweed is to pull out the plant by hand as much as possible. If you want to apply a pre-emergent herbicide, do it in September. Effective post-emergent herbicides against chickweed include 2,4D+MCPP+dicamba and 2,4D+MCPP.

Chickweed Quick Facts & Identification

Musk Thistle

Musk Thistle

Photo Credit Musk weed is a designated noxious and invasive weed in many regions of the United States.

Musk thistle is a very aggressive noxious weed of rangeland, roadsides, non-crop areas and pastures. It creates dense monocultures and chokes out local vegetation. Livestock animals tend to avoid pastures that are heavily infested with musk thistle plants. 

The key to preventing musk thistle infestation is to avoid its seed dispersal. In addition, the establishment of aggressive grasses in the given area is also a good control strategy. You can use chemical herbicides as a last resort, but it will take several applications before complete removal.

Musk Thistle Quick Facts & Identification

Scientific nameCarduus nutans
Other namesNodding thistle
Weed typeBroadleaf Biennial
Height1½ to 6 feet
IdentificationLeaves
– Leaves are deeply-lobed, sparsely hairy and have grayish margins

Frequently Asked Questions (FAQs)

How can you tell the difference between a plant and a weed?

Any plant that is growing in a place where it is not supposed to become weeds. So, the list of weeds will vary from place to place. Simply put, the difference between a weed and a plant is subjective and lies in the eye of the beholder.

What is the most effective weed killer for lawns?

Growing and maintaining a healthy lawn is the best “weed killer.” A healthy and thick lawn in itself is an excellent defense against weeds. However, if it does not work out, you will have to use chemical weed killers. In our experience, Southern Ag Amine 2,4-D Weed Killer and Roundup Concentrate Extended Control are the best weed killers to use on lawns.

Is a daisy a weed or a flower?

Once again, it is subjective. It is a weed if a daisy is growing in the middle of a turf or in any other place where it is not wanted. However, if it is being grown in flower beds or an English cottage garden, it is a flower.

Is it better to spray weeds before mowing?

If you want, you can spray weeds on your lawn after mowing. However, it is better to spray the weeds with a herbicide before mowing. It is because mowing will shed the weeds on your yard, which will make the herbicide less effective. Also, it is much harder to pull weeds that are short and mowed low.

What weed looks like a daisy?

There are many weeds that look like daisies. Common examples include Chickweed, Daisy Fleabane, Aster, Chamomile and Capeweed.

What kind of weed has thorns?

Weeds that have thorns or spines are commonly known as Spiny or Spiky Weeds. There are many weeds that have thorns or spines, such as Canada thistle, Musk thistle, Jimson weed, Spiny pigweed and lawn burweed. 

How often can you put weed killer on your lawn?

Generally, you are supposed only to put a weed killer on your lawn once or twice a year. However, in case of a severe infestation, multiple applications of the weed killer might be needed. Therefore, always consult an expert or read product instructions before herbicide use.
