Pictures Of Common Lawn Weeds In Minnesota
Below you’ll find the most frequent weeds that pop up in Minnesota lawns. Each entry includes a description, where it grows best, and how to get rid of it. Keep this page open on your phone while you walk your yard.
Dandelion
Dandelions are everywhere in Minnesota. They have bright yellow flowers that turn into white puffballs. The leaves are jagged and form a low rosette.
- When it appears: Early spring, then again in fall
- Where it grows: Thin lawns, sunny spots, compacted soil
- Control: Dig out the taproot with a weeder tool. Apply broadleaf herbicide in fall for best results.
Creeping Charlie
Creeping Charlie has round, scalloped leaves and small purple flowers in spring. It spreads along the ground, forming a dense mat.
- When it appears: Early spring, stays green all summer
- Where it grows: Shady, damp areas
- Control: Pull by hand after rain. Use a herbicide with triclopyr in fall. Improve soil drainage.
Crabgrass
Crabgrass looks like a clump of coarse, light green grass. It grows low to the ground and spreads outward.
- When it appears: Late spring, after soil warms up
- Where it grows: Thin lawns, bare spots, hot dry areas
- Control: Apply pre-emergent herbicide in early May. Pull small clumps by hand. Keep your lawn thick.
White Clover
White clover has three round leaflets and white flowers that bees love. It grows low and spreads quickly.
- When it appears: Spring through fall
- Where it grows: Low-nitrogen soil, sunny or partly shady spots
- Control: Feed your lawn with nitrogen fertilizer in spring. Pull by hand or spot-treat with broadleaf herbicide.
Ground Ivy
Ground ivy is similar to creeping Charlie but has a stronger minty smell. Leaves are kidney-shaped with scalloped edges.
- When it appears: Early spring, persists all season
- Where it grows: Shade, moist soil, under trees
- Control: Hand pull in small areas. Use a herbicide with dicamba or triclopyr in fall. Improve sunlight by pruning trees.
Yellow Nutsedge
Yellow nutsedge looks like tall grass but has a triangular stem. It grows faster than your lawn and stands out.
- When it appears: Late spring, thrives in heat
- Where it grows: Wet, poorly drained areas
- Control: Pull by hand, but get the whole root. Use a selective sedge herbicide. Fix drainage issues.
Broadleaf Plantain
Broadleaf plantain has wide, oval leaves with parallel veins. It forms a flat rosette close to the ground.
- When it appears: Spring through fall
- Where it grows: Compacted soil, foot traffic areas
- Control: Dig out the root. Aerate your lawn to reduce compaction. Spot-treat with broadleaf herbicide.
Canada Thistle
Canada thistle has spiny leaves and purple flower heads. It spreads by underground roots and can be hard to kill.
- When it appears: Late spring, flowers in summer
- Where it grows: Disturbed soil, roadsides, thin lawns
- Control: Mow regularly to prevent seeding. Use a systemic herbicide in fall. Repeat treatments may be needed.
Hairy Bittercress
Hairy bittercress forms small rosettes of rounded leaves. It produces tiny white flowers and seed pods that explode when touched.
- When it appears: Early spring, dies back in heat
- Where it grows: Moist, shady spots, garden beds
- Control: Pull before seed pods form. Mulch garden areas. Apply pre-emergent in late winter.
Chickweed
Chickweed has small, oval leaves and tiny white flowers. It grows low and forms dense mats.
- When it appears: Early spring, fall
- Where it grows: Cool, moist, shady areas
- Control: Hand pull or rake out. Use a pre-emergent in early spring. Improve air circulation.
How To Use These Pictures For Identification
Follow these steps to match weeds in your yard with the pictures above.
- Take a close-up photo of the weed with your phone. Include the leaf shape, flower, and stem.
- Compare leaf shape to the descriptions. Dandelions have jagged leaves, while creeping Charlie has round ones.
- Check the flower color. Yellow flowers often mean dandelion or nutsedge. Purple flowers suggest creeping Charlie or thistle.
- Look at the growth pattern. Does it grow in clumps (crabgrass) or spread low (clover)?
- Note the location. Shady spots favor creeping Charlie. Sunny thin areas get crabgrass.
If you’re still unsure, take a sample to your local garden center. They can help identify it and recommend products.
When To Look For Weeds In Minnesota
Minnesota’s short growing season means weeds appear in waves. Here’s a timeline:
- Early spring (April-May): Dandelions, creeping Charlie, hairy bittercress, chickweed
- Late spring (May-June): Crabgrass germinates, white clover appears
- Summer (June-August): Yellow nutsedge, Canada thistle, broadleaf plantain
- Fall (September-October): Dandelions return, chickweed reappears
Knowing the timing helps you apply the right treatment at the right moment. Pre-emergents work best before weeds sprout. Post-emergents work when weeds are actively growing.
Why Minnesota Lawns Get Weeds
Several factors make Minnesota lawns prone to weeds. Understanding these helps you prevent them.
- Thin grass: Bare spots invite weeds. Keep your lawn thick by overseeding in fall.
- Compacted soil: Heavy clay soil in many parts of Minnesota makes it hard for grass roots to grow. Aerate once a year.
- Improper mowing: Cutting grass too short stresses it. Set your mower to 3-4 inches.
- Poor drainage: Wet spots favor nutsedge and ground ivy. Improve drainage with soil amendments.
- Low fertility: Weeds like clover thrive in low-nitrogen soil. Fertilize in spring and fall.
Natural Ways To Control Weeds
If you prefer not to use chemicals, these methods work well for small infestations.
- Hand pulling: Best after rain when soil is soft. Get the whole root.
- Boiling water: Pour directly on weeds in cracks or bare spots. Be careful not to hit good grass.
- Vinegar spray: Use household vinegar on sunny days. It kills leaves but not roots, so repeat may be needed.
- Corn gluten meal: A natural pre-emergent. Apply in early spring before weeds sprout.
These methods take more time but are safe for pets and kids. For large areas, chemical controls are often more practical.
Chemical Control Options
When natural methods aren’t enough, herbicides can help. Always read labels and follow instructions.
- Pre-emergents: Apply in early May for crabgrass. Products with dithiopyr or prodiamine work well.
- Broadleaf herbicides: Use in fall for dandelions, clover, and creeping Charlie. Look for 2,4-D, dicamba, or triclopyr.
- Selective grass herbicides: For crabgrass after it appears. Products with quinclorac are effective.
- Sedge herbicides: For yellow nutsedge. Use halosulfuron or sulfentrazone.
Apply on calm days to avoid drift. Water your lawn a day before treatment for better absorption.
Preventing Weeds Year-Round
A healthy lawn is the best weed prevention. Follow this seasonal plan.
Spring (April-May)
- Apply pre-emergent for crabgrass
- Fertilize with slow-release nitrogen
- Hand pull early dandelions
- Aerate if soil is compacted
Summer (June-August)
- Mow at 3-4 inches
- Water deeply once a week
- Spot-treat visible weeds
- Pull nutsedge by hand
Fall (September-October)
- Overseed thin areas
- Apply broadleaf herbicide for winter weeds
- Fertilize for root growth
- Rake leaves to prevent smothering
Winter (November-March)
- Keep lawn clear of debris
- Avoid walking on frozen grass
- Plan your spring treatments
Common Mistakes To Avoid
Many homeowners make these errors when dealing with weeds. Avoid them for better results.
- Mowing too short: Scalping your lawn weakens it and lets weeds in.
- Overwatering: Frequent shallow watering encourages weed seeds to sprout.
- Applying herbicide at the wrong time: Fall is best for most broadleaf weeds, not spring.
- Ignoring soil health: Weeds thrive in poor soil. Test your soil pH and amend as needed.
- Using too much fertilizer: Excess nitrogen can burn grass and feed weeds.
