Say Goodbye to Clover: When & How to Reseed Your Lawn in Wisconsin
If you’re dreaming of a soft, green lawn without patches of stubborn clover, you’re not alone. In Midwest states like Wisconsin, removing clover and reseeding your yard with fresh, healthy grass is totally doable—but timing is everything.
Below, you’ll find a simple, seasonal lawn care plan to remove clover and reseed grass that works best for the unique weather patterns in the Midwest.
Step 1: Best Time to Kill Clover in Wisconsin
The most effective time to eliminate clover is in the fall, especially with a broadleaf herbicide. Why? Because clover is actively pulling nutrients into its roots to prepare for winter. That makes fall the perfect window for a weed-killing sneak attack.
👉 Pro Tip:
You can also apply weed and feed in late spring or early summer—around Memorial Day—to knock out emerging clover and other weeds.
Step 2: When to Reseed Your Lawn in Wisconsin
For cool-season grasses (which thrive in Wisconsin), the ideal time to reseed your lawn is between August 15th and September 15th.
Here’s why this sweet spot works so well:
-
Soil is still warm enough to spark fast seed germination.
-
Cooler air temps help your new grass thrive.
-
Summer weeds like crabgrass are dying off, giving your seedlings less competition.
Step 3: Wait Time Between Killing Clover and Reseeding
The type of herbicide you use matters big time when it comes to how long you should wait before reseeding your lawn. Here’s a quick guide:
| Herbicide Type | Wait Time Before Seeding |
|---|---|
| Glyphosate-based | A few days or even same day |
| 2,4-D-based | 3 to 4 weeks |
| Pre-emergent herbicide | 3 to 4 months or more |
📌 Always read the label! Herbicides vary, and you don’t want to waste seed or ruin your lawn plan by reseeding too soon.
How to Get Rid of Clover in Your Lawn: 4 Tried-and-True Methods
If clover is creeping into your yard and taking over your lawn, you’re not alone. Midwest homeowners—especially in states like Wisconsin, Illinois, and Minnesota—often face this pesky plant in the spring and summer. The good news? You have options!
There are four main ways to eliminate clover from your grass: manual removal, smothering, herbicides, and encouraging strong grass growth. Often, combining two or more methods gives you the best results. Let’s break it down.
🌿 1. Manual Removal (Great for Small Patches)
Manual removal is ideal if clover is only showing up in small areas of your yard.
Pulling:
Loosen the soil around the clover with your hands or a small garden fork, then pull out the plant, making sure to get the roots too. This helps prevent it from growing back.
Digging:
For larger patches, use a spade or digging tool to carefully remove the clover and its root system. This takes a bit of elbow grease but works well for early infestations.
👉 Tip: Moist soil makes removal easier, so try this after a rain or watering.
🛑 2. Smothering (Best for Larger Clover Patches)
This method blocks sunlight and kills clover (and anything else underneath).
Plastic Sheeting or Garbage Bags:
Cover the affected area with a heavy-duty black trash bag or plastic tarp. Secure the edges with bricks or garden staples and leave it for a few weeks. The lack of sunlight will kill the clover—but it’ll also kill the grass, so use this for tough areas you plan to reseed.
Organic Mulch:
Spread a thick layer of straw, wood chips, or newspaper over the clover to slowly block sunlight. This works best in garden beds or along the lawn’s edge where aesthetics aren’t as crucial.
💧 3. Herbicides (Selective or Natural Options)
When manual or natural methods aren’t enough, herbicides can help.
Selective Herbicides (for lawns):
Choose a post-emergent herbicide designed for broadleaf weeds. These products target clover without harming your grass. Always follow label instructions, especially when planning to reseed later.
Natural Herbicides (for spot treatment):
A vinegar-based solution (with 20-30% acetic acid) can kill clover when applied directly. Wear gloves and avoid overspray—it will kill anything green it touches.
👉 Note: Natural options are best for spot treating, not for large areas.
🌱 4. Strengthen Your Grass to Crowd Out Clover
The healthiest way to prevent clover is by making your lawn so thick and strong that weeds can’t compete.
Mow Taller:
Set your mower to 3 inches or higher. Clover hates shade, and taller grass will naturally choke it out.
Use Nitrogen-Rich Fertilizer:
Clover thrives in low-nitrogen soil. Applying a nitrogen-rich lawn fertilizer gives your grass the upper hand.
Overseed in Fall:
Thick grass is your best defense. Spread new grass seed over your lawn in late summer to early fall to fill in bare spots and reduce weed space.
Final Thoughts: The Best Way to Remove Clover in the Midwest
Clover might be stubborn, but with the right approach, you can reclaim your yard and grow a healthier, greener lawn.
Whether you’re pulling it by hand, smothering it, treating it with herbicides, or building up your lawn’s strength—consistency is key. And if you’re reseeding, don’t forget: Mid-August through mid-September is prime time in the Midwest.
Your Simple Fall Lawn Care Plan
To recap, here’s the perfect approach for a full, clover-free lawn in Wisconsin or anywhere in the Midwest:
-
Apply broadleaf herbicide in early fall to kill clover.
-
Wait the proper amount of time depending on your herbicide.
-
Spread grass seed between August 15–September 15.
-
Water consistently and avoid mowing too soon.
-
Fertilize and maintain your lawn to keep weeds from returning.
Keep Your Lawn Looking Lush
Once your lawn is filled with new, healthy grass, it’s important to keep it that way. Regular mowing (but not too short!), consistent watering, and seasonal fertilization will help crowd out weeds and keep your grass vibrant through every season.
Final Thoughts
A well-timed plan to remove clover and reseed your lawn in Wisconsin can give you the backyard of your dreams—lush, green, and perfect for summer hangouts or fall bonfires. Stick to the timeline, follow product instructions, and your lawn will thank you!
