Lawn Weed Identification: Common Lawn Weeds

Weeds are a common occurrence in most lawns and gardens. While many of them are quite familiar, there may be some that are not. Learning about some of the most common types of weeds can make it easier to eliminate them from the landscape.

How to Identify Weed Types

In order to identify weed types and bring them under control, it’s important to understand how they grow. Like other plants, weeds can be annual or perennial. Annual weeds are less troublesome as far as control measures go. While they are known to sprout up nearly anywhere due to seed dispersal, their root systems are relatively shallow. This makes them easy to pull and eradicate, although doing so before they set seed is recommended.

Common annual weeds include:

Perennial weeds, on the other hand, have more extensive root systems, including taproots, making them more difficult to control. In addition, these weeds come back each year, especially if the roots are not destroyed. Some of the most common (and problematic) perennial weed types include:

Lawn Weed Identification

One of the best ways to identify lawn weeds is by looking closely at the soil in your landscape. Many common lawn weeds can be found growing in certain types of soil, making this an excellent way to identify specific types you may have growing in your landscape. Here are some of the most commonly seen weeds:

Dandelions: Dandelions are well known in many lawns and gardens– their fuzzy yellow blooms popping up nearly anywhere. While their deep taproots make them difficult to control, they generally spread through their easily recognized white, fluffy seedheads.

Ragweed: Ragweed is commonly known by many allergy sufferers. This annual weed can be seen most often during summer (and autumn) months and recognized by its fern-like foliage.

Crabgrass: Crabgrass is a homeowner’s worst nightmare, creeping up throughout the lawn. This summer annual lies flat to the ground and has reddish purple stems (both smooth and hairy). It forms slender spike-shaped seedheads just below mowing height, making it difficult to manage.

Spotted spurge: Spotted spurge has a reddish purple spot in the center of each leaf and the sap is milky (which may cause a rash in sensitive individuals). This annual weed can be pulled up easily in moist soil. Improving the density of lawn grass can help keep it under control.

Common chickweed: Common chickweed is a mat-forming weed with tiny, star-shaped white flowers. This annual thrives when conditions are cool and moist. Mouse-ear chickweed is similar, however, this weed is perennial with hairy stems and leaves, and is more tolerant of summer heat.

White clover: White clover is a perennial weed that forms creeping runners and produces white, fluffy-looking blooms. Since this weed is a legume which fixes nitrogen, it is often found in lawns with low fertility. Adding nitrogen to the soil can help ease the population of clover.

Common nettle: This is prolific in soil that borders gardens and open fields. This perennial weed has many varieties, including stinging nettle. While it may look like an ordinary, hairy weed with attractive little flowers, it can cause a very painful sting if you touch it. Nettles can often be aggressive spreaders, with creeping roots.

Broadleaf plantain: Broadleaf plantain is a low-growing perennial. It has broad leaves with prominent veins and may smother lawn grass if left untreated, which generally calls for maintaining thick lawn coverage.

Knotweed: Knotweed is an annual weed, common along sidewalks. It usually thrives in dry, compacted soils. Knotweed forms a tough, wiry mat of stems and blue-green leaves with small white flowers. It is often confused with spurge, however, this weed does not produce a milky sap. It does produce numerous seeds, which can be reduced with annual aeration.

Ground ivy: Also known as creeping charlie, this weed is extremely difficult to control, as this creeping plant (recognized by its round, scalloped leaves, square stems, and small purplish flowers) can form large patches in shady, moist areas of the landscape.

Annual bluegrass: Annual bluegrass, also known as poa annua, is a bright green, low-growing grass that thrives in cool, moist weather. While it produces a number of white-colored seedheads and forms patches throughout the lawn, this weed is known to suddenly die out in hot, dry weather.

Winter Weeds: Common Milkweed

In late fall when I’m hiking near fields and roads I often see plants with big seed pods and white fluff tumbling out. The plants are milkweed but they look quite different from their summer appearance.

Common milkweed is a conspicuous perennial in winter because its large, warty, seed pods stand high on three to five foot stems.

The pods are fat at the bottom, pointed at the top and split open on their long edge to reveal soft, silky fluff carefully layered inside. Each wad of silk is attached to a flat, brown seed.

When exposed to the weather the silk becomes fluffy and eventually flies off the plant, carrying its seed cargo as far as it will go. The pods stand high to send their bounty on the wind.

To me one of the great mysteries of milkweed is that it looks so different in winter. In summer it’s weighed down with large, drooping, pink flower umbels but now the pods stick up alone and there are far fewer of them than the number of flowers in the umbel. I have read that only one flower in each milkweed umbel produces a seed pod. (Do any of you know how this works?)

Common milkweed is a great plant for attracting monarch butterflies to your garden. If you already have milkweed you can leave the stems standing over the winter and watch where the seeds fly.

When you’re ready to clear them away in the spring, Marcy Cunkelman suggests you save the dried stems and put them out in mid-April for the birds to use as nesting material. The fibers are strong and peel off in strips. They’re quite a favorite of Baltimore orioles.

I like milkweed, enjoyed looking for the plant. When I was in 3rd(Now here goes telling people “I am old”) our school was brought truckloads of burlap sacks to fill with milkweed pods because they were used to fill the vests the WW II GIs wore. We were all so proud doing it. This was when I lived in Gibsonia & one of the buildings you now see in a St. Barnabas Senior Community in Richland Twp. is actually our old grade school (talk about recycling!!). We had a chart in each classroom & I don’t know what the winner got, I suppose a party or something. So I always have fond memories about the milk weed. However, I did not know that the seeds were not in every pod. Some of these weeds are what keep winter in the woods interesting it seems. Everything for a purpose if only to enjoy.

I will look for pods in my fields to save for nesting material in April. Always enjoy your posts — the dried milkweed photo is great — barbara

I love milkweed too!

It smells great when the blossoms bloom. Also, when in bloom they attract a great variety of insects, bees, butterflies and the like. Monarchs and other insects make it their home for the summer season. Also, note, raising Monarch butterflies is great fun for kids and us adults too. And then, like Kate describes, gathering the silky pods in late fall for the birds in the spring for nesting material is an added bonus. So much to enjoy from a simple weed and it cost only some time.

That is the best thing about nature. It cost so little to enjoy so much. Everyday a great film is being played right outside your door. Every season brings a newly released feature film. Make some popcorn if you like and enjoy. Enjoy my friends, enjoy!

Weed Identification
Perennials 1

Weed Identification Perennials 1 is for common perennial broadleaf weeds, weed identification along with weed pictures, as well as, information on control.

On this page, you will find information on Canada Thistle, Mouseear Chickweed, White Clover, Dandelion, Field Bindweed, Ground Ivy, and Common Mallow.

A “perennial” is defined as a plant that will live for two or more years. This means that perennials will not have to come back each year by seed. (Although many perennials reproduce by seed.)

How to Use Weed Identification Perennials 1

If you have a lawn, then you know something about weeds. No lawn is immune to weed problems and they will only get worse if nothing is done. However, not all weeds can grow in lawns. The weeds that become established in lawns will be the types that can handle continuous defoliation through repeated mowing.

Weed control begins with weed identification and understanding how weeds grow, because different weeds may require different control techniques. Weeds, like some grass types, can spread by seed, rhizomes or stolons and some can regenerate from root pieces left in the soil.

Some weeds can be controlled without using chemicals, while others are almost impossible to control without them.

Weeds don’t like competition, so a thick lawn is your greatest defense against weeds. Focusing attention on weed control without building a thick turf is a guarantee you will have continued weed problems.

The weeds listed on this weed identification page is not an exhaustive list and you may have other weeds common to your geographical area. Be sure to check with your local university extension office for specific conditions in your area.

Important Note: A mention of any herbicide is not an endorsement, but is only a list of effective products. Different states or even regions within states have specific laws pertaining to herbicide use. Your local university extension office can be a great help in determining what products are available to you. Not all herbicides are available for homeowner use and the EPA is removing or adding herbicides frequently. Always use and store products according to instructions on the label.

Canada Thistle

Weed Identification

Canada thistle is an herbaceous perennial with spiny leaves and erect stems. The leaves are long and deeply lobed. They are narrowest at the base and reach their greatest width just before the tip. In pastures or other places that are not mowed frequently, the stems reach up to 4 feet tall producing a lavender or purple flower on top. It flowers from June through September.

In mowed turf, Canada thistle doesn’t produce stems or flowers, but rather takes on a rosette pattern with numerous leaves. The top photo shows what it looks like growing in a lawn. It spreads by seed and by rhizomes.

Cultural Practices

Due to the thorns on the leaves, bare hands should not touch these plants. Grabbing it by the hand will make weed identification fairly easy, however, but I wouldn’t try it. Attempts at removing this plant by mechanical means are not effective. Any root as small as an inch in length that is broken off and left behind in the soil will produce another plant. In most cases, you only succeed in producing far more plants than you started with. Research shows that a thick, vigorous growing lawn will help prevent Canada thistle from establishing.

Herbicide Use

Canada thistle can be difficult to control due to the creeping root system. Often more than one application is necessary for control. In pastures, this is an extremely invasive weed, costing millions in control and in crop losses.

In lawns, herbicides with Dicamba as the active ingredient can be used at any time of the year when the weed is actively growing. The younger the plant, the better the results. Also Clopyralid (plus 2,4-D) is a good choice. Many herbicides are formulated with three different active ingredients to provide the best results. If you purchase one of these, make sure Dicamba and 2,4-D are two of the ingredients. Always follow label instructions.

Chickweed, Mouseear

Weed Identification

Due to the small leaves, careful examination of leaves is necessary for positive weed identification. Mouseear chickweed is a winter perennial that grows vigorously in the spring. It gets its name from the shape of the leaves that resembles a mouse’s ear. It prefers to grow in full sun and can tolerate slight shade. As it grows, it hugs the ground, but will also send shoots upward.

Mowing is not an effective means of weed control, but will actually stimulate this weed to produce more shoots. It can form thick, heavy mats on the soil surface, which can choke out any grass growing within it.

For proper weed identification, look for small leaves that are approximately ½ inch long and grow opposite each other. At the end of each stem will grow a set of leave with a small, 5 white petal flower in the center. The primary method of reproduction is by seed, but it can also root at the nodes along the stem.

Cultural Practices

It is not advised to attempt pulling the plant up by hand. The fleshy stems break easily and since the stems root at the nodes, it will only cause the plant to spread faster. When pulling, the stems break where they have rooted and that rooted stem will become a new plant sending out more stems.

As with all weeds, good turf management practices that encourages a thick turf is the best method of keeping mouseear chickweed from starting. This includes proper mowing, fertilization and liming, if needed, will ensure a healthy turf.

Herbicide Use

Many herbicides are labeled for mouseear chickweed. The best time to spray is when plants are actively growing. The small, younger plants will be easier to control than the older, more established plants. It may require more than one application spaced three for four weeks apart. The small seeds will ensure new growth the following year. Spend time encouraging turf growth, which should include over-seeding or plugging if necessary. Most weeds do not like competition with vigorous growing grass.

Clover, White

Weed Identification

White clover is a common perennial legume that spreads by stolons (above ground stems) and root at the nodes. The plant has a compound leaf structure that divides into three leaflets. There is the very rare four-leaf clover (I have only seen one). Irish folklore says the person who finds it will have good luck. Some leaves contain a white stripe or watermark that is visible from several feet away. Looking for this stripe makes weed identification easy.

The flowers can reach a ½ inch in diameter and are a favorite for honeybees. The flowers are usually white, but can also be pink in color and can be seen from late spring through summer.

Cultural Practices

White clover prefers to grow in thin turf and in soil that is low in nitrogen. Maintaining a thick, vigorous turf that receives regular fertilization, as required for the grass type, will help keep clover from germinating.

Attempts at removing clover by pulling it up by hand is not effective. The stems will break at the rooted nodes. Each piece left in the soil will form another plant. In most cases, pulling it up will actually help the clover to spread faster. Chemical control is the best method of controlling white clover.

Herbicide Use

Since white clover is a winter (or cool season) perennial, it is actively growing in the cooler parts of the year. Early spring when temperatures are above 50 degrees is the best time to spray. A common herbicide called 2,4-D (Weed-B-Gone)is not effective in controlling clover. Look for herbicides that contain two or three different herbicides mixed together. Dicamba or MCPP will be effective. Not all herbicides are available to homeowners or legal in every state. You will find several herbicides are labeled for white clover. It may require an additional application three or four weeks apart for best control.

Weed Identification

Dandelions are cool season perennials and one of the most easily recognized lawn weeds. They have deeply lobed leaves with yellow flowers and white, fluffy seed heads. The white seed heads sail away in the wind and have been a long time favorite of photographers.

The dandelions have a deep taproot that slightly resembles a carrot in shape. A mature root can extend as deep as a foot into the soil. A new dandelion plant is able to regenerate from a severed portion of root left in the soil. For this reason, if pulling up the plant by hand, it is important to try and get all of the root.

For weed identification, look for leaves that are deeply lobed and form a rosette pattern on the ground. During the first year of growth, the leaves may be only a few inches long, but over time, can grow to three times that length. One to several fleshy stems can grow upward from the center of the plant. These stems grow quite rapidly after mowing and can reach their pre-cut height in only a few days.

Being cool season perennials means they are active in the cooler times of the year. Throughout most of the U.S., as temperatures warm in early summer they will go dormant, returning again in the fall as temperatures cool. However, the number of dandelions producing flowers and seed heads will be less in the fall than in the spring.

Beginning in early spring, dandelions will produce a yellow flower. The flower remains for several days until it is replaced with a white seed head. These seed heads can reach the size of a golf ball. The fluffy seeds are easily dislodged and can travel great distances in the air. These stems, flowers and seed ball are other important weed identification elements for this plant.

Seed germination is the primary method of dandelion reproduction. Lots left untreated can become overgrown with dandelions in just a few years.

Cultural Practices

Pulling dandelions is not usually an effective method of control. Any small piece of root left in the soil will produce another dandelion. If you choose not to use herbicides, make sure you get the whole root, if possible.

Herbicide Use

Dandelions are most easily controlled with postemergent herbicides. Many products are available, but most any herbicide containing 2,4-D, or 2,4-D with Dicamba will control them. Liquid formulations offer better control than most granular “weed and feed” types. If you use a granular product, use one with small flakes rather than round granules. The product needs to stick on the plant and the round granular types tend to roll off.

Field Bindweed

Weed Identification

Field Bindweed, sometimes called “creeping jenny”, is related to the morning glory plant. It is most commonly found in the Midwest and extends through central Canada. It is also found in Hawaii. Field bindweed is actually a vine and possesses all the characteristics of a vine. It can be seen growing up fences and covering shrubs and other plants. In poorly maintained lawns, it will spread out along the ground.

Field bindweed is often confused with wild buckwheat. However, wild buckwheat is an annual and has greenish flowers. Annuals will die each year and grow again from seed. These facts should help confirm a positive weed identification.

Mature, older plants have a very extensive root system. Roots can extend 15 feet into the soil and branch laterally for 20 feet or more. This complex root system makes field bindweed hard to control. Even when sprayed, it can return a short time later. Young plants, however, are easily controlled with herbicides.

The funnel shaped flowers can be white to pink and appear in late summer to fall. The plant reproduces by seed. The seeds can remain viable in the soil for many years. One university reported a seed germinating after 28 years.

Cultural Practices

Young plants may be able to be removed by pulling or hoeing. For older plants this will not work. The plant will always come back. In gardens, plastic or landscape fabric should be put down. Where field bindweed has been left uncontrolled, people have reported the plant covering all their garden plants.

Keep in mind that seeds from field bindweed can remain viable in the soil for many years. Once the plastic is removed, germination can occur, starting a new crop. If you live in an area where field bindweed is a serious problem, you will need to consider what measures you will take to control it. Chemical herbicides are about the only sure way of controlling this pest.

Herbicide Use

Chemical control is the most effective way of controlling mature field bindweed plants. Several broadleaf systemic herbicides are labeled for this pest. For mature plants, it may take a couple of years to completely kill this plant. Look for dicamba plus 2,4-D, or triple herbicide products.

Weed Identification

Ground ivy, sometimes called creeping Charlie, is a perennial weed that can grow very quickly in thin turf. It was once planted as a shade ground cover, but because of its aggressive nature, is now considered a pest. Ground ivy spreads by above ground, laterally growing stems, called stolons. These stolons can outpace the growth of turfgrass. This is especially true in shaded areas. However, in lawns with thin turf, ground ivy will grow equally well in both shade or full sun.

For positive weed identification, look for leaves growing on a long petiole, positioned opposite each other on square stems. In the spring you can see small blue flowers in the shape of a funnel which will help with weed identification. Ground ivy is similar in appearance and sometimes mistaken for another lawn weed called “common mallow”.

Cultural Practices

Ground ivy is difficult to remove without the use of herbicides. Unless the entire runner is removed, it will re-establish. The runners root at the nodes, so if you break the runner at any point, it will continue to grow. If your neighbors have it in their yard, it will only be a matter of time before it spreads into yours. If possible, encourage your neighbors to begin controlling it.

Herbicide Use

Many herbicides are labeled for ground ivy. It will generally need several applications spaced approximately 4 weeks apart for best control. Ground ivy behaves as a cool season perennial, so the best time to spray is when it is actively growing in the spring and fall. Persistence is the key.

Use products containing Dicamba plus 2,4-D or triple herbicide products.

If your neighbors are unwilling to work with you in controlling this pest, then a barrier may be needed to keep it out of your yard.

Mallow, Common

Weed identification

Common mallow is an annual, but can be a perennial is some areas. It is similar in appearance to ground ivy, but positive weed identification is easy when the root is exposed. Mallow has a tap root and the stems do not form nodes. (Nodes are swollen areas along the stem with cells that are able to produce roots and/or vegetation. Plants with nodes can be more difficult to control.) It reproduces by seed and spreads by producing stems that grow along the surface of the ground.

Cultural Practices

Maintaining a dense, vigorous turf is the best way to prevent mallow from establishing. Once established, it is possible to pull up the plants since each plant has a single tap root. Try to remove the entire taproot. Spot spaying with a selective herbicide labeled for mallow can also be effective.

Herbicide Use

If you decide to use herbicides for control of common mallow, it is best to spray when the plant is young and growing. Homeowner herbicides containing 2,4-D and MCPA is a good combination that will control this weed. Using a “sticker/spreader” according to label rates will help with chemical absorption into the plant tissue. A sticker/spreader, when added to the herbicide formulation, allows the herbicide to not only stick to the plant surface, but spread out evenly.
