How to Get Rid of Wildflowers: 9 Tips to Get Rid of Unwanted Flowers

You’ve been admiring your wildflowers in your yard, but now they seem to be taking over and crowding out the plants you actually want to see. If this describes your current situation, you may be wondering how to get rid of wildflowers and reclaim your yard, or if it even can be done at all! 

Fortunately, there are plenty of ways to get rid of wildflowers, and with these 9 tips, you’ll be well on your way to getting rid of that unwanted beauty.

1) Exclude unwanted flowers from the start

The best way to get rid of wildflowers is to prevent them from growing in the first place. Here are a few tips on how to control wildflowers from the very beginning.

1. Mow your lawn regularly. This will prevent wildflower seeds from taking root.

2. Pull up wildflowers as soon as you see them. The longer they are in the ground, the harder they will be to remove.

3. Use herbicides specifically designed for killing wildflowers. These can often be purchased at hardware stores or garden centers. Always read and follow instructions carefully before using herbicides, and wear protective clothing when spraying weed killer. 

4. Put down an organic weed killer that is not harmful to people or pets (like soap-based weed killers). You can purchase these at garden centers or online. 

5. If there are large areas of weeds, use fertilizer that contains ingredients such as corn gluten meal or soybean meal. Corn gluten meal helps keep pesky weeds from sprouting by starving them out with nitrogen, while soybean meal prevents weeds from spreading their roots into other areas. 

6. Plant tall grasses like rye along property lines, which will help block sunlight and slow the growth of unwanted plants like wildflowers. 

7. Spade up your lawn occasionally and plant cool season grasses such as tall fescue, perennial rye or ryegrass which will help block sunlight and prevent weeds from growing. 

8. Apply pre-emergent herbicide about three weeks before planting time to inhibit weed seed germination. However, this type of herbicide cannot be used near desirable plants like flowers or vegetables so make sure it does not come into contact with those crops. 

9. Spray grass seed over bare spots, so weeds won’t have any room to grow; then keep watering until the new seedlings are established enough to stand up against weedy competition.

You can follow these to stop the wildflowers to grow from very start of it.

2) Try spraying plants with vinegar

White vinegar is a herbicide that will kill most plants, including wildflowers. 

To use it, mix one part vinegar with three parts water in a spray bottle and apply it to the leaves of the plant. You may need to reapply every few days, but eventually the plant will die. 

Be careful when using vinegar around other plants, as it can kill them too. 

There are some specific strategies for managing these weeds. Some common methods include deep tilling or ripping up particularly if you want to do this often, mowing the area regularly, killing off the flowers before they go to seed, or using herbicides such as white vinegar.

3) Use herbicides sparingly

You don’t need to use a lot of herbicide to get rid of wildflowers. In fact, using too much can actually do more harm than good. Instead, focus on using it sparingly and only in areas where the wildflowers are really taking over. 

Here are some tips for controlling them in your grass.

Mow high and often

If you’re dealing with unwanted flowers that have invaded your lawn, mowing at a height of 3 inches is one way to control them. Ideally, you’ll want to mow every week during the hottest months of summer. 

Use mulch

If you live in an area that experiences cold winters, use mulch as another way to keep unwanted flowers from coming back year after year. Mulching not only helps control weeds but also helps protect against soil erosion. 

It also offers several other benefits such as boosting soil fertility, keeping down the amount of fertilizer needed and reducing the need for irrigation. 

Mulching will also help make your lawn look nicer because it covers up unsightly spots or bald patches in your yard. For example, if there’s a spot in your yard where nothing ever grows, you could cover it with a layer of mulch. 

When the sun heats up this mulch, it will release moisture into the ground, which creates a perfect environment for new plants to grow. Once these plants start growing, they’ll eventually fill in those bare spaces and outcompete any remaining weeds that may be left behind. 

Using straw or hay

There are a few other ways to prevent the invasion of unwanted wildflowers. One way is by using straw or hay for temporary weed control until the desired turfgrass species establish themselves. 

Using nonselective herbicide

Use a nonselective herbicide sparingly as directed. Nonselective herbicides will kill just about any plant they come in contact with, so you want to make sure you only use them when absolutely necessary. 

Remember that they can also kill desirable plants too, so you want to stay away from using them whenever possible.

4) Kill unwanted flowers with fire

One way to get rid of wildflowers is to kill them with fire. This method is especially effective if the wildflowers are in grass. 

To do this, you will need a flamethrower or a weed torch. You will also need to be careful not to damage the surrounding vegetation. 

First, identify the area that you want to treat. 

Then, clear away any dead leaves or other debris. 

Next, position the torch so that the flame is touching the base of the plant. After about 30 seconds, pull back and watch for 30 more seconds. 

Repeat this process as required until all unwanted plants have been killed. Be sure to maintain at least 10 feet from any combustible materials when using a weed torch.

5) Overwater until flowers wilt

One way to get rid of wildflowers is to overwater the area until the flowers wilt. This method works best on small patches of wildflowers. 

To do this, water the area around the wildflowers heavily for a few days straight. The flowers will start to wilt and eventually die. It may take more than one try with this method before all the flowers are gone. 

A few other tips for how to control wildflowers in grass include using corn gluten meal or cornstarch near the plants, spraying vinegar or coffee grounds on them, and turning up sprinklers at night when it’s cooler out.

6) Prevent spread of seeds

One way to prevent the spread of wildflower seeds is to mow your lawn regularly. This will cut down on the number of flowers that are able to bloom and produce seeds. You can also rake up any flowers that do bloom and dispose of them in a bag or compost bin.  

Remove weed-prone areas from your yard so that you can easily spot when new plants start growing and get rid of them as soon as possible. 

For an extra precaution, you may want to hire a professional gardener who has experience with eliminating weeds in different types of yards. If these measures don’t seem like they’re enough, there are many other ways to get rid of unwanted wildflowers, such as hand pulling or using herbicides.

7) Remove wildflower roots

One way to get rid of wildflowers is to remove the roots. 

This can be done by digging up the root system or using a herbicide. If you dig up the roots, make sure to remove as much of the root system as possible. 

If you use a herbicide, be sure to follow the directions on the label and only apply it to the area where you want to get rid of the wildflowers. 

Do not spray herbicides near any body of water. You should also wait for at least three days before mowing your lawn again after applying a herbicide so that the grass can recover from being sprayed with chemicals. 

For persistent wildflower problems, consider planting other flowering plants in your yard or garden to provide food for pollinators instead.

8) Trap and eat unwanted bees

If you have wildflowers in your garden that you don’t want, there are a few things you can do to get rid of them. You can try pulling them up, but they’ll probably just grow back. You could also try using herbicides, but these can be harmful to the environment. 

A more natural way to get rid of wildflowers is by trapping and eating the bees that pollinate them. This may sound like a lot of work, but it’s actually quite simple. All you need to do is find a trapor make one yourself with some aluminum foil and an apple or other fruit with sugar inside. 

The fruit will attract the bees while they’re inside the trap, where they won’t be able to pollinate any flowers because their wings will stick together from being covered in sugar!

9) Spray with glyphosate (Roundup or any other herbicide)

The best way to get rid of wildflowers is to spray them with glyphosate. Glyphosate is a herbicide that will kill any plant it comes in contact with, so it’s perfect for getting rid of unwanted flowers. 

However, be careful not to apply too much, or you’ll also end up killing the grass and other plants you want. To avoid this, just use Roundup as directed on the label and spot treat only the areas where there are weeds or wildflowers. 

The next time you notice weeds or unwanted plants starting to grow, be sure to follow these simple steps and keep your yard looking its best!

Frequently asked questions (FAQs)

How do I get rid of wildflowers in my lawn?

If you’re looking for long-term solutions, consider replacing your lawn with native grasses or other ground cover that’s less susceptible to weed invasion. There are also products available, such as dandelion killer from Scotts, that selectively kill broadleaf weeds while leaving lawns intact.

Do wildflowers come back every year?

As a rule, weed seeds remain viable for up to three years. This means that wildflower seeds planted in 2018 will germinate again in 2021and maybe even as soon as 2020 if conditions are right. But by treating your lawn with a herbicide before weeds have a chance to establish themselves, you can get ahead of your weeds and reduce unwanted reseeding in future years.
