The autumn is the ideal season for controlling wild violets. The weed is a perennial with a protracted tap root. Use a broadleaf killer that contains 2,4-D or Dicamba to destroy the violets only; the grass won’t be harmed. Drive is a fantastic wild violet herbicide (quinclorac). Quinclorac is marketed under many names in other lawn weed control solutions.
Because the leaf surfaces of violets are so waxy, adding a spreader-sticker product to the herbicide mixture will improve the herbicide’s adhesion to the leaf surfaces and increase control. Visit your neighborhood garden center and request a spreader-sticker product.
One treatment is insufficient. Multiple treatments will be required. Applications used in the spring or summer merely burn back the leaf tissue; the plants will eventually regrow. Herbicides used in the fall have better effectiveness controlling plants because they move down into the tap root.
How can I naturally get rid of violets in my lawn?
To get rid of wild violets, combine horticultural vinegar and water to make a DIY weed killer. You can mix vinegar and water at a ratio of 80% to 20%. When applied to the foliage of the problematic plant, this homemade wild violet weed pesticide has an 80 percent control rate against the majority of broadleaf weeds. For every gallon of water used, add 1 teaspoon of a non-ionic surfactant or dishwashing liquid if the horticultural vinegar does not already contain one.
When working with horticultural vinegar, exercise caution. It is significantly stronger than regular kitchen vinegar and can seriously harm your skin and eyes. When working with horticultural vinegar, be cautious to wear safety gear. Wearing long sleeves, rubber gloves, pants, and safety glasses can help you avoid getting vinegar in your eyes and on your skin.
Will African violets be harmed by Roundup?
With the help of Roundup Ready-To-Use Weed & Grass Killer III with Sure Shot Wand, eliminate wild violets that are growing in your landscaping and flower beds. The best time of year to treat them is in the fall when the active ingredient is readily transferred to the root system, just like wild violets growing in the lawn.
Which chemical will effectively eradicate wild violets?
The best herbicides for controlling wild violet species are those that include triclopyr; nevertheless, for effective control, repeated application over the course of the growing season and over several years may be required.
Why is my yard being overrun by violets?
Many people consider the lawn to be a sacred space where neither dandelion nor clover dare to grow. Some people are diversifying their lawns to attract more bees or to stop fighting weeds altogether. I had never seen violets in turf before; dandelions and clover may come to mind first when thinking of weeds in lawns.
Untrained eyes may suppose creeping charlie or dead nettle, two common weeds with purple flowers, are the source of this purple colour in the lawn from a distance.
But as I looked closer, they were violets! Though one of our turf lecturers explained that wild violets are actually one of the most infamous lawn weeds and are challenging to maintain, I mistakenly thought of this as the pot of gold at the end of the rainbow.
Violets (viola sp.) spread by rhizomes and seeds. They are available in purple, white, and yellow tones. Some are two-tone.
Violets draw pollinators and serve as the main host plant for the fritillary butterfly group’s caterpillars. The mining bee Andrena violae, a specialized bee that exclusively visits violets, likewise relies only on them for food.
Violets thrive in moist, shaded locations where the turf is weak and unable to cope with the weeds and violets. Violets may be a welcome choice for ground covers in these situations, which frequently provide difficulties for turf development. Once established, though, they have the potential to grow from that difficult place onto your ideal lawn sections.
Violets can also indicate areas where lawns are being mowed too short, which inhibits their ability to regrow thickly and vigorously. This is a sign that lawns are becoming thinner overall.
You get to decide, of course! Do they need to stay? OR ought they to leave? OR, as a reader suggested, WHY NOT BOTH? Those discovered at Chadwick were a pleasant sight to run in this spring and appear to have integrated themselves into the show. This is a nice illustration of how some natural places may add color, beneficial insects, and perhaps cover some problematic spots to a lawn’s aesthetics.
There are options if you want to manage your violets in lawns. Digging and manually pulling them might be the best method for control if a patch is discovered early. Take into account the site’s conditions as well. Is it possible to make a turf stand that is thicker so that it can outcompete weeds or increase light penetration? The application of post-emergent broadleaf herbicides with the active component Triclopyr is one method of chemical control for violets. To have an effect on established violets, two or more applications would be necessary. Application in the fall is thought to be most efficient because plants are focusing their energy on their roots. Violets are challenging to control, even with a good solution. They are resilient little things. Make sure you read all labels and follow directions before applying insecticides. The law for usage is on the label.
What should I do about the purple flowers on my lawn?
Wild violet is one of the toughest weeds to eradicate from a lawn. It’s possible that this native plant appears delicate and charming, especially in the spring when it blooms with lovely purple flowers. However, in actuality, it is a vindictive weed with an odd flowering characteristic that produces dense mats of leaves that can choke out your lawn.
Wild violets are hardy plants that can withstand drought. However, moist soil is the best environment for them, which this year’s above average rainfall has given. This has caused the weed to thrive and spread rapidly.
The well-known purple (or occasionally white, bicolored, or speckled) flowers that wild violets produce in the spring are frequently mowed down. A other kind of self-pollinating bloom, however, that remains below the leaves or even underground in the summer and produces seeds that are dispersed in the vicinity, can be produced by violets. Because these blossoms won’t be cut down, a lot of seeds will be dispersed. In addition, they propagate via underground stems. They can eventually develop dense colonies by utilizing these two techniques.
It is possible to control wild violets, but it requires work and repeated treatment. Wild violets will more easily absorb herbicides into their root systems in the fall as they get ready for winter, making this the best time to control them.
You must employ systemic non-selective herbicides because of their thick, energy-storing roots. Glyphosate (Roundup) will work, but it might require a few weeks between each treatment. Non-selective herbicides will also destroy any plant they come into touch with, including grass, so either use a cardboard barrier to protect the surrounding area or use a brush to apply the herbicide solely to the violets.
To be effective, selective broadleaf weed herbicides must list wild violet on the label. A product containing dicamba and triclopyr is also a possibility, but again, it might require numerous applications to entirely remove established plants.
Although non-selective herbicides like Roundup and organic herbicides are effective, it often requires multiple applications to achieve control since the roots can be challenging to eradicate.
You will need to use a pre-emergent herbicide in the spring and fall after controlling the existing plants on your lawn to stop the numerous seeds the violets have already dispersed from germinating. Maintaining a lush, healthy lawn that stops weeds from taking root provides further suppression.
What do the little purple flowers on my grass represent?
Here in Tulsa, it appears that winter is loosening its grasp and spring is beginning to establish itself. The temperature is decreasing. Trees are starting to leaf out and bloom. Lawns made of fescue are becoming a deeper green. Additionally, you may observe henbit flowers coloring the local lawns purple all around the city.
A perennial winter weed called henbit is a member of the mint family. The square-shaped stem and minty scent of these purple blossoms can be felt by rubbing the stem between your fingers. These weeds can reach a height of 12 inches or more if untreated and unmowed, and they frequently produce purple blooms. Henbit competes with healthy grass for soil resources, like all weeds do, and can seriously damage your lawn.
Applying a fall pre-emergent weed control is the best way to get rid of these purple flowers as well as other winter annual weeds. Your soil will be protected by a layer during the fall treatment, preventing weed seeds from developing into tough-to-control plants. These winter annuals can be handled with a post-emergent, though, if you missed the fall pre-emergent.
Due to the milder temperatures in the spring, post-emergent weed management can be a little slower to kill weeds. The process can take several weeks, but eventually the plant will absorb the post-emergent and the weeds will start to die. The best thing you can do as a homeowner is cut the weeds down five to seven days after we apply the product. This will hasten the decomposition process and hasten the beginning of your lawn’s transformation.
Can lime eliminate violets?
Q. Mike: My issue is violets. I do not want to use chemicals (which are ineffective anyway) or tear up my lawn and start again. What can I do to get rid of these obstinate little weeds?
- Rockville, Maryland’s Peter (PS: I was captivated after discovering your show on the Sirius ‘NPR Talk’ channel!)
Although we can grow grass “OK,” we can actually grow violets for some reason. They are encroaching on the lawn. The weed killer my husband uses appears to simply promote them, and removing them one by one takes a lot of effort. Do you have any suggestions?
In Severna Park, Maryland, Laurie
I have a front yard that gets some sun and has good grass, a few “typical” weeds, and a lot of violets. I only fertilize the lawn once a year in the spring and keep the grass cut quite high. I’ve attempted throughout the years to consistently apply lime in the fall because I’ve heard that violets prefer acidic soil. I’ve also tried repeatedly spraying with a potent mixture of “Weed-B-Gon,” but that hasn’t either. Anything else I can do?
In Pittsburgh, Brian
Help me get rid of the wild violets, Mike. Commercial weed killers are simply ineffective.

A. The answer is no. Wild violets are almost completely immune to chemical herbicides, according to Iowa State University Professor and frequent You Bet Your Garden turf grass expert Nick Christians, Ph.D., in his classic book “Lawns.” When all other weeds in the grass have been eliminated, “they frequently survive.”
However, that caution follows his opening statement, which says: “Violets have a lovely blue blossom and are not always undesirable in a lawn.” Now, this isn’t coming from some organic Miracle-Gro-confiscating, left-leaning, tree-hugging enthusiast like me. Dr. Nick employs chemical herbicides even though he popularized the use of corn gluten meal as a natural, pre-emergent herbicide. And HE advises us to think about just letting violets be.
I might also mention that early lawns were intended to sprout attractive things. Early seed mixtures included clover as a necessary component, and a lawn devoid of clover was viewed as having been neglected. Additionally, a lot of individuals continue to plant little summer-blooming bulbs directly in their lawns, such grape hyacinth, crocus, species tulips, and scilla. The blossoms will have withered by the time the turf needs its first Spring cut, and the leaves will have absorbed enough solar energy to emerge and delight once more the following year.
Otherwise, our Pittsburgh listener is right; soil that is too acidic does support the growth of violets. They also flourish on soils that lack calcium. So lime might aid in controlling their spread. But instead of assuming how much to apply, have your soil tested and abide by the instructions. (Or use 1.5 times as much hardwood ash; for further information on substituting wood ashes for lime, read THIS PREVIOUS QUESTION OF THE WEEK.)
Nick continues, “The other elements of good lawn care—mowing, watering, and feeding appropriately for your particular turf—are also crucial.” For example, that Pittsburgh lawn needs to be nourished in the fall to stay strong enough to fend off violets.
Chemical pesticides are extremely ineffectual against this lovely plant, as Nick and all of our Questioners point out. With that Roundup and Weed B Gon, all you’re doing is contaminating your neighbors’ well, killing frogs and toads, and raising your risk of developing Parkinson’s disease in the future. So stop it now!
Dig up the clumps if you MUST have an artificially perfect, environmentally negligent, mono-cultural, and criminally warm-blooded lawn; the plant is easy to identify thanks to its heart- or kidney-shaped leaves. Utilize a poachers spade to dig down and collect all the roots. Fill the holes with compost and grass seed to create a lush stand of replacement turf by performing this task in the fall for cool-season lawns and in the spring for warm-season ones. Or, if it’s simply a personal thing for you, say your mother was afraid of gentian while carrying you. Dig out the clumps and replace them with little Spring bulbs.
Or you could move them. I absolutely adore wild violets, so if I see one in the “wrong” location, I just relocate it to a location where I want more color in the Spring or pollination assurance. Your violets will attract local bees looking for summer residences in the spring, and they’ll stick around and pollinate the rest of your plants all season. Or perhaps you didn’t want a lot of fruit and flowers?
And lastly, eating wild violets are excellent. They taste delicious and look great embellishing salads. They are the center of “candied violets.” Additionally, they are a fantastic source of rutin, a rare nutrient that fortifies capillary walls and prevents or reverses the appearance of varicose and spider veins.
Long-time listeners are aware of the fact that I frequently advise people to collect and consume their pansy flowers for this reason. All Viola species have rutin in their blossoms, and as our dear friend Jim Duke, Ph.D., a former USDA researcher and best-selling book, has frequently pointed out, a plant’s wild form typically has considerably higher quantities of naturally occurring nutrients than its cultivated counterpart.
Start eating your wild violets instead of fighting them (and Johnny jump-ups)! You’ll look better in a bathing suit and live longer, which is arguably more significant.
