Photo Credit: Matt Lavin<\/a> \/ Flickr \/ CC BY 2.0<\/a><\/figcaption><\/figure> Canada thistle can produce allelochemicals that stunt the growth of nearby plants, making sure it’s the star of your yard, whether you like it or not.<\/p>
- Appearance: <\/strong>Its leaves are shallow-lobed and toothed, with spiny margins. The upper surface of the leaves is dark green and smooth, while the underside is light green and covered with woolly hairs. Reaching up to 3 feet tall, this weed can quickly become a towering nuisance on your lawn.<\/li> <\/ul>
- Germination:<\/strong> From June through August, Canada thistle displays its purplish-pink flowers. These blooms produce numerous seeds equipped with “parachutes,” allowing them to ride the wind and spread far and wide. Additionally, this weed has a robust underground root system that helps it to regenerate and pop up in new spots.<\/li> <\/ul>
2. Common Chickweed<\/h2>

Photo Credit: Lazaregagnidze<\/a> \/ Wikimedia Commons \/ CC BY-SA 4.0<\/a><\/figcaption><\/figure> Common chickweed is a winter annual broadleaf weed that likes shady, moist areas. It\u2019s even bold enough to grow in mulch, making it a persistent nuisance for gardeners.<\/p>
- Appearance:<\/strong> Common chickweed forms a low, rounded mound of leaves. Its prostrate stems sometimes root at the nodes. The roots are fibrous. The leaves are opposite, very small, and smooth, with a pointed tip and teeth on the edges. The flowers are small, featuring five deeply divided petals that appear as 10.<\/li> <\/ul>
- Germination:<\/strong> Common chickweed germinates from seed in late summer or early fall. Once established, it thrives in the cooler months, taking advantage of the shady, moist areas in your lawn and garden beds.<\/li> <\/ul>
3. Crabgrass<\/h2>
![\"close-up](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/08\/Crabgrass.jpg\")
Photo Credit: Harry Rose<\/a> \/ Flickr \/ CC BY 2.0<\/a><\/figcaption><\/figure> Crabgrass loves to invade Indiana lawns. It is an aggressive warm-season annual that loves to outcompete cool-season turfgrasses<\/a> when the summer sun turns up the heat and rain becomes scarce.<\/p>
- Appearance:<\/strong> Its leaves are broader than the average grass blades, growing in clumps close to the ground and resembling a crab’s legs, hence the name. You can notice its light yellow color, but as it matures, its leaves take on a dark red shade.<\/li> <\/ul>
- Germination: <\/strong>Crabgrass is a master at survival and proliferation. It germinates in the spring. It can produce thousands of seeds in a single season during the hot Indiana summer.\u00a0<\/li> <\/ul>

Photo Credit: f99aq8ove<\/a> \/ Flickr \/ CC BY-SA 2.0<\/a><\/figcaption><\/figure> Dandelions can pop up anywhere, turning your well-manicured lawn into a mess.<\/p>
- Appearance: <\/strong>Dandelions are short-lived perennials with deep and thick taproots that extend up to 3 feet long, making them tough to eradicate. Their jagged-edged leaves and hollow, leafless stems end in a bright yellow flower head. This flower will later turn into a fluffy white head. If you cut any part of this plant, it oozes a milky white juice.<\/li> <\/ul>
- Germination:<\/strong> Dandelions bloom from March to November. Its yellow flowers transform into white seed heads, each capable of holding up to 20,000 viable seeds.<\/li> <\/ul>

5. Ground Ivy<\/h2>
![\"closeup](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/ground-ivy.jpg\")
Photo Credit: Andreas Rockstein<\/a> \/ Flickr \/ CC BY-SA 2.0<\/a><\/figcaption><\/figure> Ground ivy is a perennial broadleaf weed that invades Indiana lawns and landscapes. It prefers moist, fertile, and shady spots but is tough enough to tolerate full sun as well.<\/p>
- Appearance:<\/strong> Ground ivy is easy to recognize because of its leaves which are kidney-shaped, about an inch wide, and have scalloped edges. They grow opposite each other on long petioles and almost encircle the petiole. When crushed, the leaves emit a minty scent.<\/li> <\/ul>
- Germination:<\/strong> Ground ivy produces small purple flowers in May, but they are often overlooked. This weed forms long, slender stolons that root at the nodes, making it an aggressive spreader. Its ability to root at multiple points makes it particularly difficult to control.<\/li> <\/ul>
6. Leafy Spurge<\/h2>
![\"Leafy](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/09\/48184815692_52d84598cd_c-1.jpg\")

- Appearance:<\/strong> Leafy spurge grows in clusters with upright stems that reach 3 to 4 feet tall. It has showy, yellowish-green, heart-shaped bracts that enclose small flower clusters. If you break a stem of the plant, it releases a toxic, milky sap that can cause blisters on your skin and even permanent blindness if it gets in your eyes.<\/li> <\/ul>
- Germination:<\/strong> Leafy spurge blooms from late spring to mid-summer. Each flower produces an average of 140 seeds, making it a prolific spreader. It has deep taproots and extensive lateral roots, making it a tough competitor for your lawn’s resources.<\/li> <\/ul>
7. Nutsedge<\/h2>
![\"Nutsedge\"](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/09\/18839918805_18a46e827d_c-1.jpg\")
Photo Credit: New York State IPM Program at Cornell University<\/a> \/ Flickr \/ CC BY 2.0<\/a><\/figcaption><\/figure> Nutsedge, also known as nutgrass, is a fast-growing perennial that loves to invade Indiana lawns. Despite its name, it\u2019s not actually grass, it’s an aggressive weed that can outcompete your turf, especially during the hot summer months.<\/p>
- Appearance: <\/strong>Nutsedge stands out from your typical grass blades because it tends to grow a bit taller and has a pale green color. Its strands grow faster than most grasses. You can identify nutsedge by its stems, which grow in a distinctive \u201cV\u201d shape.<\/li> <\/ul>
- Germination:<\/strong> Nutsedge appears in the spring and continues to grow actively until the first frost in autumn. It produces flowers and seeds in clusters of short spikes. This weed can form underground structures called nutlets. These small, round nutlets can lie dormant for 10 years, waiting for favorable conditions to sprout.<\/li> <\/ul>

8. Poison Ivy<\/h2>
![\"Poison](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2023\/06\/poison-ivy.jpg\")
Photo Credit: James St. John<\/a> \/ Flickr \/ CC BY 2.0<\/a><\/figcaption><\/figure> Poison ivy is a perennial poisonous broadleaf weed that can turn any Indiana lawn into a risky venture. Whether in the sun or shade, this troublesome plant is a master of disguise and irritation.<\/p>
- Appearance:<\/strong> Poison ivy can grow as a woody shrub or a vine. Its leaves are alternate, each featuring three large leaflets. The edges of these leaflets may or may not be toothed, and their shape can vary widely. Contact with poison ivy can cause a rash and intense itching because of the oil resin present on the plant.<\/li> <\/ul>
- Germination: <\/strong>Poison ivy becomes more noticeable during the spring and summer months. It produces greenish-yellow flowers in clusters at the leaf axils. This weed spreads by seeds, creeping roots, and stems that root wherever they touch the ground. Birds often eat the seeds, contributing to its widespread distribution.<\/li> <\/ul>
Note:<\/strong> Poison ivy leaves can be confused with maple tree seedlings because of their similar-looking leaves.<\/p>

9. Quackgrass<\/h2>
![\"Quackgrass\"](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/09\/3739406828_bee3c0169d_c-1.jpg\")
Photo Credit: Matt Lavin<\/a> \/ Flickr\/ CC BY-SA 2.0<\/a><\/figcaption><\/figure> Quackgrass is the resilient lawn invader that keeps Indiana gardeners on their toes. This aggressive cool-season perennial isn’t picky about its environment. It can grow in everything from partly shaded nooks to full sun. <\/p>
- Appearance: <\/strong>Quackgrass grows unbranched and upright, reaching 4 feet tall. Its ashy blue-green leaves roll in the bud. A pair of narrow auricles clasp the stem at the base of each leaf blade. <\/li> <\/ul>
- Germination: <\/strong>It germinates in the spring and sets seed in late summer. While it can reproduce by seed, many of those seeds are sterile. The real menace lies in its underground network of rhizomes, which spread fast. <\/li> <\/ul>
10. White Clover<\/h2>
![\"white](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/06\/24858550106_0af3b45250_c.jpg\")

- Appearance: <\/strong>Wild violet forms a rounded clump about 5 inches high. Its heart-shaped, waxy leaves have a long petiole, with the blade often cupping toward it. The flowers are a lovely sight with five petals that range in color from blue to violet.<\/li> <\/ul>
- Germination:<\/strong> Wild violet flowers germinate in the spring. However, once the temperatures rise in summer, the flowers fade. This weed forms rhizomes that allow it to spread and establish itself on your lawn.. <\/li> <\/ul>
FAQ About Weeds in Your Indiana Lawn<\/h2>
How can I get rid of weeds on my Indiana lawn?<\/h3>

- 8 Best Post-Emergent Herbicides [Reviews]<\/a><\/li>
- Types of Post-Emergent Herbicides<\/a><\/li>
- Germination:<\/strong> Wild violet flowers germinate in the spring. However, once the temperatures rise in summer, the flowers fade. This weed forms rhizomes that allow it to spread and establish itself on your lawn.. <\/li> <\/ul>
- Appearance: <\/strong>Wild violet forms a rounded clump about 5 inches high. Its heart-shaped, waxy leaves have a long petiole, with the blade often cupping toward it. The flowers are a lovely sight with five petals that range in color from blue to violet.<\/li> <\/ul>
- Germination:<\/strong> White clover germinates from April to December. Its aggressive stems and shallow roots enable it to spread above and below the ground.\u00a0<\/li> <\/ul>
- Appearance: <\/strong>White clover is easy to spot for its white flowers. Each stem features clusters of more than five blossoms, and its three rounded leaflets give it a characteristic look. <\/li> <\/ul>
- Germination: <\/strong>It germinates in the spring and sets seed in late summer. While it can reproduce by seed, many of those seeds are sterile. The real menace lies in its underground network of rhizomes, which spread fast. <\/li> <\/ul>
- Appearance: <\/strong>Quackgrass grows unbranched and upright, reaching 4 feet tall. Its ashy blue-green leaves roll in the bud. A pair of narrow auricles clasp the stem at the base of each leaf blade. <\/li> <\/ul>
- Germination: <\/strong>Poison ivy becomes more noticeable during the spring and summer months. It produces greenish-yellow flowers in clusters at the leaf axils. This weed spreads by seeds, creeping roots, and stems that root wherever they touch the ground. Birds often eat the seeds, contributing to its widespread distribution.<\/li> <\/ul>
- Appearance:<\/strong> Poison ivy can grow as a woody shrub or a vine. Its leaves are alternate, each featuring three large leaflets. The edges of these leaflets may or may not be toothed, and their shape can vary widely. Contact with poison ivy can cause a rash and intense itching because of the oil resin present on the plant.<\/li> <\/ul>
- Germination:<\/strong> Nutsedge appears in the spring and continues to grow actively until the first frost in autumn. It produces flowers and seeds in clusters of short spikes. This weed can form underground structures called nutlets. These small, round nutlets can lie dormant for 10 years, waiting for favorable conditions to sprout.<\/li> <\/ul>
- Appearance: <\/strong>Nutsedge stands out from your typical grass blades because it tends to grow a bit taller and has a pale green color. Its strands grow faster than most grasses. You can identify nutsedge by its stems, which grow in a distinctive \u201cV\u201d shape.<\/li> <\/ul>
- Germination:<\/strong> Leafy spurge blooms from late spring to mid-summer. Each flower produces an average of 140 seeds, making it a prolific spreader. It has deep taproots and extensive lateral roots, making it a tough competitor for your lawn’s resources.<\/li> <\/ul>
- Appearance:<\/strong> Leafy spurge grows in clusters with upright stems that reach 3 to 4 feet tall. It has showy, yellowish-green, heart-shaped bracts that enclose small flower clusters. If you break a stem of the plant, it releases a toxic, milky sap that can cause blisters on your skin and even permanent blindness if it gets in your eyes.<\/li> <\/ul>
- Germination:<\/strong> Ground ivy produces small purple flowers in May, but they are often overlooked. This weed forms long, slender stolons that root at the nodes, making it an aggressive spreader. Its ability to root at multiple points makes it particularly difficult to control.<\/li> <\/ul>
- Appearance:<\/strong> Ground ivy is easy to recognize because of its leaves which are kidney-shaped, about an inch wide, and have scalloped edges. They grow opposite each other on long petioles and almost encircle the petiole. When crushed, the leaves emit a minty scent.<\/li> <\/ul>
- Germination:<\/strong> Dandelions bloom from March to November. Its yellow flowers transform into white seed heads, each capable of holding up to 20,000 viable seeds.<\/li> <\/ul>
- Appearance: <\/strong>Dandelions are short-lived perennials with deep and thick taproots that extend up to 3 feet long, making them tough to eradicate. Their jagged-edged leaves and hollow, leafless stems end in a bright yellow flower head. This flower will later turn into a fluffy white head. If you cut any part of this plant, it oozes a milky white juice.<\/li> <\/ul>
- Germination: <\/strong>Crabgrass is a master at survival and proliferation. It germinates in the spring. It can produce thousands of seeds in a single season during the hot Indiana summer.\u00a0<\/li> <\/ul>
- Appearance:<\/strong> Its leaves are broader than the average grass blades, growing in clumps close to the ground and resembling a crab’s legs, hence the name. You can notice its light yellow color, but as it matures, its leaves take on a dark red shade.<\/li> <\/ul>
- Germination:<\/strong> Common chickweed germinates from seed in late summer or early fall. Once established, it thrives in the cooler months, taking advantage of the shady, moist areas in your lawn and garden beds.<\/li> <\/ul>
- Appearance:<\/strong> Common chickweed forms a low, rounded mound of leaves. Its prostrate stems sometimes root at the nodes. The roots are fibrous. The leaves are opposite, very small, and smooth, with a pointed tip and teeth on the edges. The flowers are small, featuring five deeply divided petals that appear as 10.<\/li> <\/ul>
- Germination:<\/strong> From June through August, Canada thistle displays its purplish-pink flowers. These blooms produce numerous seeds equipped with “parachutes,” allowing them to ride the wind and spread far and wide. Additionally, this weed has a robust underground root system that helps it to regenerate and pop up in new spots.<\/li> <\/ul>
