Common Lawn Weeds In Mississippi

Mississippi’s long, hot growing season allows tropical and subtropical weed species to establish themselves in lawns. Understanding the common lawn weeds in mississippi is the first step to keeping your yard healthy and green throughout the year.

Weeds love the heat and humidity here. They pop up fast and spread even faster if you ignore them. But don’t worry—you can manage them with the right knowledge and a little effort.

Mississippi lawns face a unique mix of warm-season and cool-season weeds. The state’s climate means you’ll see different weeds in spring, summer, and fall. Some weeds are annuals, dying after one season. Others are perennials, coming back year after year from roots or seeds.

Below is a breakdown of the most common weeds you’ll find in Mississippi lawns. Each section covers identification, growth habits, and control methods.

Broadleaf Weeds

Broadleaf weeds have wide, flat leaves with a central vein. They stand out against the narrow blades of grass. These weeds are easy to spot but hard to eliminate if you don’t act quickly.

Dandelion

Dandelions are everywhere in Mississippi. Their bright yellow flowers turn into puffballs of seeds that blow across your lawn. Each plant has a deep taproot that can reach 10 inches or more.

Appearance: Jagged, lobed leaves forming a rosette. Yellow flower heads on hollow stems.
Growth: Perennial. Blooms in spring and fall.
Control: Pull them when the soil is moist. Use a broadleaf herbicide in early spring or fall.

Chickweed

Chickweed loves cool, moist weather. It forms dense mats that choke out grass. You’ll see it in late winter and early spring.

Appearance: Small, oval leaves. Tiny white flowers with five petals.
Growth: Annual. Spreads by seeds and creeping stems.
Control: Apply pre-emergent herbicide in late fall. Hand-pull small patches.

Henbit

Henbit looks similar to chickweed but has purple flowers. It grows quickly in shady, damp areas. It can take over a lawn if left unchecked.

Appearance: Square stems, scalloped leaves. Purple-pink flowers in whorls.
Growth: Annual. Germinates in fall, blooms in early spring.
Control: Mow before it flowers. Use post-emergent herbicide in late winter.

Wild Violet

Wild violets are tough perennials with heart-shaped leaves and purple flowers. They spread by seeds and underground rhizomes. They thrive in shady, moist spots.

Appearance: Glossy, dark green leaves. Purple or white flowers in spring.
Growth: Perennial. Forms dense colonies.
Control: Dig out the roots. Use a selective broadleaf herbicide with triclopyr.

Grassy Weeds

Grassy weeds look like your lawn grass but grow faster and coarser. They blend in at first, then stand out when they seed. They are harder to control than broadleaf weeds.

Crabgrass

Crabgrass is the most common grassy weed in Mississippi. It germinates in late spring and grows fast in hot weather. It forms ugly clumps that ruin a smooth lawn.

Appearance: Wide, light green blades. Stems grow outward from the center.
Growth: Annual. Produces thousands of seeds per plant.
Control: Apply pre-emergent herbicide in early spring. Pull or spot-treat with post-emergent.

Bermudagrass

Bermudagrass is both a lawn grass and a weed. If you don’t want it, it invades flower beds and fescue lawns. It spreads by runners and seeds.

Appearance: Fine, gray-green blades. Creeping stems that root at nodes.
Growth: Perennial. Very aggressive in warm weather.
Control: Dig out the runners. Use a non-selective herbicide like glyphosate in spot treatments.

Nutsedge

Nutsedge looks like grass but isn’t. It has triangular stems and grows faster than lawn grass. It thrives in wet, poorly drained soil.

Appearance: Shiny, yellow-green leaves. Three-ranked leaves from the base.
Growth: Perennial. Spreads by tubers (nutlets) underground.
Control: Improve drainage. Use a selective herbicide with halosulfuron.

Goosegrass

Goosegrass is similar to crabgrass but tougher. It grows in compacted soil and along driveways. It has a distinctive white center at the base.

Appearance: Flat, dark green blades. Stems flatten against the ground.
Growth: Annual. Germinates later than crabgrass.
Control: Aerate compacted soil. Apply pre-emergent in late spring.

Other Common Weeds

Some weeds don’t fit neatly into broadleaf or grassy categories. They have unique growth habits that require special attention.

Dollarweed

Dollarweed looks like a tiny lily pad. It grows in wet areas and spreads by seeds and rhizomes. It’s common in lawns with poor drainage.

Appearance: Round, scalloped leaves. Small white flowers.
Growth: Perennial. Thrives in soggy soil.
Control: Fix drainage issues. Use a herbicide with 2,4-D or dicamba.

Florida Betony

Florida betony is a mint family weed with square stems and white flowers. It produces crunchy, white tubers that look like rattlesnake rattles.

Appearance: Toothed leaves on square stems. White flowers in spring.
Growth: Perennial. Spreads by tubers and seeds.
Control: Dig out the tubers. Apply a broadleaf herbicide in fall.

Lespedeza

Lespedeza is a low-growing weed with small, clover-like leaves. It forms mats in thin lawns. It’s common in poor soil.

Appearance: Three leaflets. Small purple flowers in summer.
Growth: Annual or perennial depending on species.
Control: Fertilize to thicken the lawn. Use a herbicide with metsulfuron.

How To Identify Weeds In Your Lawn

Identifying weeds correctly is crucial. If you use the wrong herbicide, you might kill your grass or waste money. Here’s a simple process to identify common lawn weeds in mississippi.

Look at the leaf shape. Broadleaf weeds have wide leaves. Grassy weeds have narrow, parallel-veined leaves.
Check the growth habit. Does it grow upright, spread out, or form a rosette?
Note the flower color and shape. Many weeds have distinctive flowers.
Feel the stem. Square stems mean it’s in the mint family.
Consider the season. Some weeds appear only in spring or fall.

Take a photo and compare it to online resources. Your local county extension office can also help with identification.

Prevention Tips For Mississippi Lawns

Preventing weeds is easier than removing them. A healthy, thick lawn is your best defense. Weeds can’t grow where grass is dense and strong.

Mow At The Right Height

Mowing too low stresses grass and lets sunlight reach weed seeds. Set your mower blade to 3 to 4 inches for most grasses. Taller grass shades the soil and keeps weed seeds from germinating.

Water Deeply But Rarely

Frequent, shallow watering encourages weed growth. Water your lawn deeply once or twice a week. This promotes deep roots in grass and dries out weed seeds on the surface.

Fertilize Properly

Weeds love thin, weak lawns. Apply fertilizer based on your grass type and soil test results. Over-fertilizing can feed weeds too. Use a slow-release nitrogen fertilizer in spring and fall.

Aerate Compacted Soil

Compacted soil favors weeds like goosegrass and nutsedge. Aerate your lawn once a year in spring or fall. This improves water and air flow to grass roots.

Overseed Thin Areas

Bare spots are invitations for weeds. Overseed these areas with the same grass type as your lawn. Keep the seeds moist until they germinate.

Control Methods For Common Weeds

When prevention isn’t enough, you need to take action. There are several ways to control common lawn weeds in mississippi. Choose the method that fits your lawn and your comfort level.

Manual Removal

Hand-pulling works for small patches. Use a weeding tool to get the whole root. Pull after rain when the soil is soft. For taproots like dandelion, you need to remove the entire root or it will regrow.

Herbicides

Herbicides are effective but must be used carefully. There are two main types:

Pre-emergent herbicides: Stop weed seeds from germinating. Apply in early spring for summer weeds, and in early fall for winter weeds.
Post-emergent herbicides: Kill weeds that are already growing. Apply when weeds are young and actively growing.

Always read the label. Some herbicides kill all plants, including grass. Others are selective and only target broadleaf weeds.

Natural Alternatives

If you prefer not to use chemicals, try these methods:

Corn gluten meal: A natural pre-emergent that stops seed germination.
Vinegar solutions: Household vinegar can kill young weeds, but it may harm grass.
Boiling water: Pour it on weeds in cracks or bare spots.

Seasonal Weed Calendar For Mississippi

Knowing when weeds appear helps you plan your control efforts. Here’s a seasonal guide for common lawn weeds in mississippi.

Spring

Spring brings a flush of cool-season weeds. Chickweed, henbit, and wild violet bloom early. Crabgrass seeds start germinating when soil temperatures reach 55°F.

Apply pre-emergent for crabgrass in March or April.
Spot-treat broadleaf weeds with post-emergent herbicide.
Pull dandelions before they go to seed.

Summer

Summer is peak weed season. Crabgrass, goosegrass, and nutsedge grow fast. Dollarweed appears in wet areas.

Mow high to shade out weeds.
Hand-pull nutsedge before it forms tubers.
Use post-emergent herbicide for grassy weeds.

Fall

Fall is the best time to control perennial weeds. They store energy in their roots, so herbicides work well. Winter annuals like henbit start germinating.

Apply pre-emergent for winter weeds in September.
Treat broadleaf perennials with herbicide.
Aerate and overseed thin areas.

Winter

Winter weeds are mostly dormant. But some, like chickweed, can grow in mild spells. Focus on planning for spring.

Monitor for winter weeds and pull them.
Clean and sharpen mower blades.
Test soil pH and adjust if needed.

Common Mistakes When Dealing With Weeds

Even experienced homeowners make mistakes. Avoid these common errors to keep your lawn healthy.

Applying herbicide on windy days. It can drift onto flowers or vegetables.
Using too much herbicide. More isn’t better and can harm grass.
Mowing too short. It weakens grass and encourages weeds.
Ignoring soil health. Weeds thrive in poor, compacted soil.
Not reading herbicide labels. Each product has specific instructions.

When To Call A Professional

Some weed problems are too big for DIY methods. If you have a severe infestation of nutsedge or bermudagrass, consider hiring a lawn care service. Professionals have access to stronger herbicides and equipment.

Also call a pro if you’re unsure about weed identification or herbicide selection. A mistake can damage your lawn and cost you time and money.
