Pictures Of Common Lawn Weeds In Tennessee
Below, you’ll find detailed descriptions and visual cues for the top weeds in Tennessee. We’ll cover broadleaf weeds, grassy weeds, and a few tricky perennials. Each section includes practical tips for control.
Dandelion
Dandelions are everywhere in Tennessee. Their bright yellow flowers turn into puffballs that spread seeds across your lawn. The leaves form a rosette close to the ground.
- Appearance: Deeply toothed leaves, single yellow flower on a hollow stem.
- Season: Blooms spring through fall.
- Control: Pull them by hand when soil is moist. Use a broadleaf herbicide in early spring.
Clover (White And Red)
Clover is common in Tennessee lawns, especially where soil is low in nitrogen. It spreads quickly and can choke out grass.
- Appearance: Three round leaflets, small white or pink flowers.
- Season: Active from spring to fall.
- Control: Improve soil fertility with nitrogen fertilizer. Spot-treat with a clover-specific herbicide.
Crabgrass
Crabgrass is a summer annual that loves thin lawns. It grows low and spreads outwards, creating unsightly patches.
- Appearance: Light green, coarse blades that form a star-like pattern.
- Season: Germinates in late spring, thrives in summer.
- Control: Apply pre-emergent herbicide in early spring. Maintain thick grass to block sunlight.
Chickweed
Chickweed is a winter annual that pops up in cool weather. It forms dense mats that smother grass.
- Appearance: Small, oval leaves, tiny white flowers with five petals.
- Season: Active from fall through spring.
- Control: Hand-pull or use a post-emergent herbicide in late fall.
Henbit
Henbit is often mistaken for deadnettle. It has square stems and purple flowers, common in disturbed soil.
- Appearance: Rounded, scalloped leaves, purple tubular flowers.
- Season: Blooms in early spring.
- Control: Mow before it seeds. Apply a broadleaf herbicide in fall.
Nutsedge (Yellow And Purple)
Nutsedge isn’t a grass—it’s a sedge. It grows faster than lawn grass and has a triangular stem. It’s tough to control.
- Appearance: Shiny, yellow-green leaves, seed heads that look like little umbrellas.
- Season: Active in summer.
- Control: Use a sedge-specific herbicide. Improve drainage to reduce moisture.
Wild Violet
Wild violet is a perennial that spreads by seeds and underground stems. It’s common in shady, moist areas.
- Appearance: Heart-shaped leaves, purple or white flowers in spring.
- Season: Blooms in spring, leaves persist all year.
- Control: Dig out roots carefully. Apply a triclopyr-based herbicide in fall.
Plantain (Broadleaf And Narrowleaf)
Plantain is a low-growing weed with ribbed leaves. It thrives in compacted soil.
- Appearance: Broad, oval leaves (broadleaf) or long, narrow leaves (narrowleaf). Tall flower spikes.
- Season: Active spring through fall.
- Control: Aerate soil to reduce compaction. Spot-treat with a broadleaf herbicide.
Ground Ivy (Creeping Charlie)
Ground ivy is a creeping perennial that forms dense mats in shade. It has a minty smell when crushed.
- Appearance: Round, scalloped leaves, purple funnel-shaped flowers.
- Season: Active spring and fall.
- Control: Hand-pull in small areas. Use a herbicide with dicamba in fall.
Bermudagrass
Bermudagrass is a warm-season grass that can invade fescue lawns. It spreads aggressively by runners.
- Appearance: Fine, gray-green blades, wiry stems that root at nodes.
- Season: Active in summer, goes dormant in winter.
- Control: Difficult to remove. Use a non-selective herbicide and reseed with fescue.
How To Use These Pictures For Identification
When you spot a weed, compare it to the descriptions above. Look at leaf shape, flower color, and growth habit. Take a photo with your phone for reference.
- Check the leaf edges: smooth, toothed, or lobed?
- Look at the stem: round or square?
- Note the flower: size, color, and number of petals.
- Observe where it grows: sun or shade, wet or dry soil.
Tools For Better Identification
You don’t need a botanist’s kit. Use these simple tools:
- Your phone camera: Take close-ups of leaves and flowers.
- A ruler: Measure leaf length and flower size.
- A weed identification app: Many are free and accurate.
- A local extension office: They offer free ID services.
Why These Weeds Thrive In Tennessee
Tennessee’s weather is a weed’s dream. Mild winters let winter annuals like chickweed survive. Hot, humid summers boost crabgrass and nutsedge. Plus, the state’s clay soil holds moisture, which many weeds love.
Soil Conditions Matter
Compacted soil favors plantain and ground ivy. Low nitrogen encourages clover. Acidic soil (common in East Tennessee) can promote moss and wild violet. Test your soil every few years to know what you’re dealing with.
Lawn Care Habits
Mowing too short stresses grass and lets weeds in. Watering lightly encourages shallow roots, which weeds exploit. Fertilizing at the wrong time can feed weeds instead of grass.
Prevention Tips For Tennessee Lawns
Stop weeds before they start. A healthy lawn is your best defense.
- Mow high: Keep grass at 3-4 inches to shade out weed seeds.
- Water deeply: Soak once a week rather than daily sprinkles.
- Fertilize correctly: Use a slow-release nitrogen fertilizer in fall for cool-season grasses.
- Aerate annually: Reduces compaction and improves root growth.
- Overseed thin areas: Fill bare spots with grass seed in early fall.
Seasonal Calendar For Weed Control
Timing is everything. Here’s a simple schedule:
- Late winter: Apply pre-emergent for crabgrass and other summer annuals.
- Early spring: Spot-treat broadleaf weeds like dandelion and henbit.
- Summer: Hand-pull or treat nutsedge and bermudagrass.
- Fall: Apply pre-emergent for winter annuals like chickweed. Also, treat perennial weeds like wild violet.
Natural And Chemical Control Methods
You have options. Choose what fits your lawn and lifestyle.
Manual Removal
Hand-pulling works for small infestations. Use a weeding tool to get the roots. Do this after rain when soil is soft.
- For dandelions: Use a long-handled dandelion digger.
- For crabgrass: Pull before it seeds in late summer.
- For nutsedge: Dig out the tubers—breaking them off makes it worse.
Organic Options
Some natural products work well:
- Corn gluten meal: A pre-emergent that stops seed germination.
- Vinegar-based sprays: Effective on young weeds in sunny spots.
- Boiling water: Kills weeds in cracks and patios.
- Mulch: Blocks light and prevents weed seeds from sprouting.
Chemical Herbicides
Use chemicals as a last resort. Always read the label.
- Pre-emergents: Apply before weed seeds germinate. Examples: prodiamine, dithiopyr.
- Post-emergents: Kill existing weeds. Look for 2,4-D, dicamba, or triclopyr for broadleaf weeds.
- Non-selective: Glyphosate kills everything. Use only for spot treatment.
Common Mistakes To Avoid
Even experienced gardeners make errors. Here’s what to watch for:
- Applying herbicide when rain is forecast—it washes away.
- Using the wrong product for the weed type.
- Mowing too short after treatment—reduces effectiveness.
- Ignoring soil health—weeds love poor soil.
- Treating in extreme heat—can damage grass too.
When To Call A Professional
Some situations need expert help. Consider a lawn care service if:
- Weeds cover more than 50% of your lawn.
- You have persistent nutsedge or bermudagrass.
- You’re unsure about chemical application.
- You have a large property.
