Lawn care in Minnesota can be a challenge, especially with so many common lawn weeds to contend with. Dandelions, for example, are one of the most recognizable and widespread weeds in the state.
They can be found in almost every yard, and their bright yellow flowers are a sign that they're taking over. According to the article, dandelions can grow up to 12 inches tall and produce up to 2,000 seeds per plant.
To get rid of them, it's best to use a combination of physical removal and herbicides. The article recommends using a pre-emergent herbicide in early spring to prevent dandelion seeds from germinating.
For existing dandelion plants, a post-emergent herbicide can be used to kill the weeds. It's also a good idea to mow your lawn regularly and water it deeply to help prevent weeds from growing back.

Why You Have Weeds
Weeds can grow in tough conditions, such as soil compaction, high pH, lack of nutrients, over-watering, under-watering, and heavy shade.
Soil compaction is a major issue that can lead to weed growth - it's like a blanket of hardness that prevents water and nutrients from reaching your grass.
Weeds thrive in high-pH soil, which can be caused by too much lime or other alkaline substances.
Lack of nutrients is another common problem that weeds love to exploit - they're like the opportunistic freeloaders of the plant world.
Over-watering and under-watering can both create an environment that weeds find irresistible - it's like a never-ending buffet of water and nutrients for them.
Heavy shade can also lead to weed growth, especially if it's caused by trees or other plants that block sunlight from reaching your grass.

Weeds can grow in tough conditions, such as soil compaction, high pH, lack of nutrients, over-watering, under-watering, and heavy shade.
Soil compaction can be a major issue, making it difficult for grass to grow and allowing weeds to take over.
Weeds can dominate over turfgrass unless the underlying issues are addressed.
Timing Is Everything
Weeds can seem to pop up overnight, but the truth is they've been germinating in the soil for weeks or months.
In Minnesota, the ideal time to control broadleaf lawn weeds is between May and October when they're actively growing.
Those pesky spring weeds actually germinate in the fall, so it's essential to have a proactive care program in place.
Spring preventative treatments are based on soil temperature, and here in Minnesota, that means our start time can range from March to May.
Curative weed spray treatments occur from April through early October, and it's crucial to apply them during the hot and dry summer months to avoid damaging the turf.
If your lawn looks healthy, it's tempting to skip weed prevention, but remember, those seeds can hang out for years, waiting to turn into ugly weeds.
ID!
The most common types of broadleaf weeds in Minnesota are Dandelion, Plantain, and Thistle.
Dandelion is a common sight in Minnesota lawns, with its bright yellow flowers and jagged leaves.
Plantain is another weed that's easy to spot, with its broad leaves and tall stems.
Thistle, on the other hand, has a distinctive purple flower and prickly leaves that can be a real nuisance to lawns.
If you're having trouble identifying the weeds in your lawn, start by looking for these common characteristics: broad leaves, tall stems, and distinctive flowers.
The type of weed you have can also give you a clue about how to get rid of it - for example, if you have Dandelion, you may want to try digging it up or using an herbicide to kill it.
Weed Control in Minnesota
The best time to control and treat broadleaf lawn weeds in Minnesota is when they are actively growing, usually between May and October.
During the hot and dry summer months, grass may go dormant, and that's when weed problems become very obvious.

Additional Control Measures
A healthy lawn is key to controlling weeds in Minnesota. A well-maintained lawn can outcompete weeds for resources like water and nutrients.
Good lawn care practices include proper watering, mowing, and fertilizing. Poor watering and mowing practices can lead to disease, weed infestation, and a high-maintenance lawn.
Using a sharp blade when mowing is essential. Dull blades tear grass, making it dry out faster and leaving it vulnerable to disease.
Beware of mowing your grass too short. Grass is at its best when mowed to a height between 3 and 4 inches.
Don't remove more than 1/3rd of the grass at any mowing. Cutting grass too short can result in shallow roots, making it more susceptible to disease and weed problems.

Specific Weeds in MN
Dutch White Clover is a common lawn weed in Minnesota. It thrives in cool, moist soils and can outcompete your grass, leaving you with a patchy lawn.
If you're dealing with a small patch of clover, try hand-pulling it. Good soil nutrient levels are key to reducing clover growth, and clover often means nitrogen levels are low in the soil.
Herbicide treatments can be effective, but timing is everything. Look for herbicides with ingredients like Clopyralid, Dicamba, or Metsulfuron, and apply them in the fall.
Crabgrass
Crabgrass is a warm-season annual that can produce as many as 150,000 seeds, making it a significant problem in Minnesota lawns.
Crabgrass seeds are incredibly resilient and can remain dormant in the soil for years, waiting for the right conditions to germinate. This means that even if you successfully remove the existing crabgrass, new seeds can still sprout up in the future.
Pre-emergent treatment is crucial in preventing crabgrass from taking hold, but it's not foolproof. Even with pre-emergent treatment, crabgrass can still sneak through in thinner areas or along edges.
Crabgrass is often compared to a crab due to its sprawling, crab-like growth pattern. This unique growth habit allows it to spread quickly and take over patches of your lawn.

Applying a pre-emergent herbicide in the spring can help suppress crabgrass, but it's not a guarantee of total control. In fact, even with pre-emergent treatment, crabgrass can still be a problem, especially in areas with poor soil or thin lawn.
Crabgrass can be a huge pain to deal with, but with the right approach, you can keep it under control. By maintaining a healthy lawn and using pre-emergent treatment, you can reduce the chances of crabgrass taking over your lawn.
Crabgrass seeds are photosensitive and need light to germinate. This means that bare areas or hot spots in your lawn can be especially prone to crabgrass growth.
Crabgrass can be controlled with post-emergent herbicides, but this can be undesirable due to the color effect these herbicides have on crabgrass, which can leave it looking blueish or white for weeks after treatment.

Tips for a Healthy Lawn
A healthy lawn is the best defense against weeds. Keeping your lawn thick and healthy will make it harder for weeds to take over.
Proper watering is key to a healthy lawn. Water your lawn deeply and infrequently, aiming for about 1-1.5 inches of water per week.
Mowing your lawn correctly is also crucial. Always use a sharp blade, and never remove more than 1/3rd of the grass at any mowing. Cutting your grass too short can lead to shallow roots and make it more vulnerable to disease and weeds.
Taller grass grows stronger roots and keeps the soil cooler, making it harder for weeds to thrive. Aim to mow your lawn to a height of 3-4 inches.
Here are some specific mowing tips to keep in mind:
- Use a sharp blade to avoid tearing the grass.
- Mow your lawn when it's dry to prevent spreading diseases.
- Leave the clippings on the lawn to act as a natural fertilizer.
Weed Control Process
Weed control isn't a one-time thing, it's a continuous process that requires regular attention. Different common lawn weeds in Minnesota are active at different times of year.
Many of the peskiest spring weeds actually germinate in the fall, so it's essential to be proactive and catch them before they take over. The best time to control and treat broadleaf lawn weeds in Minnesota is when they are actively growing–usually between May and October.
To control weeds effectively, you need to be mindful of the weather conditions, especially during the hot and dry summer months. Grass may go dormant, making it more vulnerable to disease and weed problems.

- Always use a sharp blade to avoid tearing the grass.
- Mow your grass to a height between 3 and 4 inches to keep it healthy.
