Identification of Wild Onion Plants

how to get rid of wild onion
Wild onions are difficult to identify and often confused with wild garlic. Their distinguishing features include thin, waxy, spear-like leaves and white bulbs. It’s important to differentiate between them to effectively control the growth of these weeds in gardens or lawns.

Thin, Waxy, Spear-like Leaves and White Bulbs

You’ll recognize wild onion plants by their thin, waxy, spear-like leaves and white bulbs – a sight sure to be etched in your memory. Controlling the spread of these pesky weeds can be achieved through natural methods such as removing clumps with a spade or trowel without shaking off excess dirt, applying non-selective herbicides or boiling water on affected areas, and monitoring the area for regrowth.

Herbicide safety should always be taken into consideration when preparing soil for planting, as it’s difficult to apply due to the thin, waxy covering of leaves often found on these plants. Wild Onions can grow back at least once if not removed early in spring or late summer before they form aerial bulblets (bulbs).

Identifying symptoms is key when determining whether you’re dealing with Wild Onions or Wild Garlic, so make sure you have all that down pat before proceeding!

Often Confused With Wild Garlic

You may often find yourself confused between Wild Onion and Wild Garlic, so it’s important to investigate the difference. Both are difficult weeds to control in gardens and lawns. Wild Onion has thin, waxy spear-like leaves with white bulbs, while Wild Garlic is a winter perennial weed that goes dormant during summer. It produces three different types of underground bulbs and mowing doesn’t kill them, but weakens them enough to prevent bulblets.

Postemergence herbicides containing 2,4-D, dicamba, mecoprop, or imazaquin are some of the most effective methods, if used over at least two years. Nonselective herbicide such as Glyphosate also works for non turf areas, but application must be done carefully due to the thin waxy covering on leaves.

To ensure total elimination, you’ll need determination and hard work. This includes regular monitoring and multiple applications, making timing crucial, especially during fall and early spring before warm weather sets in again.

Methods to Get Rid of Wild Onions

Methods to Get Rid of Wild Onions
Getting rid of wild onions and garlic in your garden or lawn can be tricky, but don’t give up!

The first thing to keep in mind is that you shouldn’t hand-pull them as this will only spread the bulbs.

Instead, use a combination of methods such as non-selective herbicides applied at the right time, or boiling water to kill them off completely.

If needed, use postemergence herbicides over multiple seasons for consistent results.

Don’t Hand-pull Wild Onion or Garlic

Don’t be tempted to hand-pull wild onion or garlic—this won’t effectively remove them. Weed management requires a combination of cultural control, shallow cultivation, and biological control practices for optimal results.

For chemical control methods of both wild onion and garlic: treat the area with a non-selective herbicide like glyphosate; boil water over the infestation (not recommended around plants); or apply three-way broadleaf herbicides containing 2,4-D, dicamba, and mecoprop in fescue lawns or warm season turfgrass areas. Image Nutsedge Killer Concentrate & RTS may also work on wild garlic in bermudagrass, zoysiagrass, and centipede lawns while metsulfuron can reduce their presence if applied correctly according to label instructions.

Postemergence herbicides should be used with persistence for effective weed removal methods—remember that thin, waxy leaves make it difficult for proper uptake!

How to Kill Wild Onion and Garlic

To thoroughly squash wild onion or garlic, don’t be fooled into believing hand-pulling’s the answer—it won’t cut it! Non-selective herbicide treatments like boiling water can help, but for complete control, mulching strategies, cultural controls such as soil amendment and fertilizing practices together with pre emergent herbicides are all needed.

Image Nutsedge Killer Concentrate & RTS is effective in controlling wild garlic in bermudagrass lawns. Three way broadleaf herbicides containing 2,4-D dicamba and mecoprop work best on fescue lawns. Glyphosate effectively controls wild garlic in non turf areas.

To get rid of surviving plants after application of these products, mow immediately before treatment to improve uptake. Timing sprays correctly is key; treat during fall or early spring when daily temperatures exceed 60°F Celsius. WG Herbicide also does the trick, especially if applied when warm temperatures prevail.

Metsulfuron containing products like Scotts Spot Weed Control Granules for Southern Lawns target both onions and garlic well. But take care not to apply them too soon on newly seeded grasses until they’re well established, nor on overseeded annual ryegrass at least 8 weeks afterwards.

Finally, adding a non ionic surfactant such as Southern Ag Surfactant improves adherence, thus increasing penetration. Though this may cause a temporary yellowish hue.

With persistence using this combination approach, one can expect successful results against even the toughest weeds like wild onion plaguing flower beds!


To effectively control wild onions, combine a variety of methods: removing bulbs with spades or trowels; treating the area with herbicides or boiling water; and monitoring for regrowth. Prevention’s key – regular mowing and soil amendments reduce bulblets. Thin waxy leaves make it hard to apply broadleaf herbicides, so multiple applications over multiple years may be necessary. When removing larger clumps, don’t pull them out – it’ll cause more bulblets to sprout up faster. Use a spade or trowel around the edges until you’ve removed all parts of the plant. Treat any remaining areas with non-selective herbicide or boiling water – both are effective. Monitor your lawn regularly for re-growth and retreat if needed, following best practices. Persistence is essential. With determination and hard work, you can eliminate these unsightly invasions from your landscape!

Suggested Herbicides for Bermudagrass, Zoysiagrass, and Centipedegrass

Suggested Herbicides for Bermudagrass, Zoysiagrass, and Centipedegrass
For effective control of wild onion in Bermudagrass, Zoysiagrass and Centipedegrass lawns, use an herbicide like Image Nutsedge Killer Concentrate & RTS for the best results. Non-selective chemical controls, such as glyphosate, are also effective but it’s important to consider cultural practices before applying them. Soil treatments with preemergence herbicides can help reduce weeds from germinating; however, they won’t affect existing plants or bulbs already present in the soil.

Control of wild onion requires a combination of methods, including hand pulling where practical and timely application of suitable post emergence herbicides when necessary. For Bermudagrass, Zoysiagrass and Centipedegrass, three-way broadleaf herbicides containing 2-4D, dicamba and mecoprop provide consistent results, while imazaquin-containing products like Celsius WG Herbicide have shown good activity against wild garlic on these turfgrass species too. Metsulfuron-containing products such as Scotts Spot Weed Control and Weed Control Granules for Southern Lawns can be used to target both wild onions and garlic effectively, if applied properly following label instructions carefully.

The thin waxy covering on leaves makes successful applications difficult, so persistence is key. Spray more than once over two seasons or longer if needed. Mowing immediately prior may improve efficacy somewhat too!

Suggested Herbicides for Both Cool Season and Warm Season Turf

Suggested Herbicides for Both Cool Season and Warm Season Turf
If you’re looking for a way to get rid of wild onion, three-way broadleaf herbicides containing 2,4-D, dicamba and mecoprop can be effective on both cool season turf and warm season turf. Glyphosate is another nonselective herbicide that’ll provide control in non-turf areas.

Metsulfuron-containing products like Scotts Spot Weed Control or Weed Control Granules for Southern Lawns are also an option.

Routine weed prevention maintenance is necessary to reduce future infestations of both wild onion and onion grass.

Diligent effort, proper use of three-way broadleaf herbicides, and other steps can help keep these pesky plants out of your yard for good – transitioning into subsequent treatments like glyphosate as needed.


For a more comprehensive solution, glyphosate can be used to effectively control wild onion and garlic in non-turf areas. It has the ability to provide long-lasting weed resistance when applied properly and with caution, as it’s known for its impact on soil health.

When controlling large areas, use of glyphosate is recommended due to its effectiveness. But for smaller infestations, natural remedies such as boiling water should be considered.

Caution must be taken not to affect seed germination. Herbicides containing three-way broadleaf ingredients such as 2,4-D, dicamba, and mecoprop shouldn’t be used in warm season turf situations, as these chemical compounds are persistent throughout the growing season, and could potentially affect new plants emerging from seeds planted later that year.

With careful consideration given towards usage rates specified by manufacturers’ instructions, and proper application techniques through either sprayer or spreader equipment (depending on the size of the treatment area), desired results can be achieved while avoiding negative consequences associated with overuse or incorrect dosage levels for this particular type of weed control situation involving wild onions & garlics.

Metsulfuron-containing Products

Take control of wild onion and garlic with metsulfuron-containing products like Scotts Spot Weed Control and Weed Control Granules for Southern Lawns! These herbicides provide consistent results over two years, making them an effective way to get rid of the pesky weed.

Metsulfuron-containing products also contain three different types of underground bulbs that can be eliminated with persistence. For optimal effectiveness, spot spraying is recommended as opposed to non-selective or pre-emergence applications, which may cause damage to desirable turfgrass varieties.

Adding a non-ionic surfactant such as Southern Ag Surfactant for Herbicides will help improve adherence and penetration into the waxy coating on leaves, while avoiding potential temporary yellowing caused by other chemical treatments such as 2-4D or vinegar-based solutions in mulching situations.

With these tools at your disposal, you’re well equipped to take back your lawn from wild onion infestations. Now all that remains is taking action! To further increase efficacy when controlling this troublesome weed, switch gears now by exploring the benefits offered by glyphosate treatments.

Celsius Wg Herbicide

Celsius WG Herbicide is an effective way to control wild garlic, especially when applied on days with temperatures over 60°F. One farmer in the Midwest eliminated their wild garlic infestation after several applications over two years.

When using the herbicide, consider the label instructions and early treatment of affected areas. Pre emergent control can also help prevent weeds from taking hold. Natural solutions may offer chemical-free alternatives.

Three-way Herbicides for Residential Lawns

For residential lawns, three-way herbicides containing 2,4-D, dicamba, and mecoprop can help fight wild garlic and onion. They’re easy to use; just mix with a non-ionic surfactant according to the label instructions for best results.

Wild onions are tricky to control because their thin waxy leaves make proper application of herbicide challenging. But these three-way herbicides will eliminate wild onion and garlic from your residential lawn without damaging the grass or other plants.

Manual removal is possible on small infestations, but mechanical control using mower height adjustment or cultural methods like fall tillage in vegetable gardens may be required for larger areas where large patches have become established over time due to inadequate maintenance practices like mowing too low each spring season.

Suggested Herbicides for Non-turf Areas

Suggested Herbicides for Non-turf Areas
For non-turf areas, glyphosate is an effective herbicide to take control of wild onion. It can penetrate waxy layers into the weeds’ tissue. It’s non-selective, so use it cautiously, according to the USDA-NRCS Plants Database.

Spraying techniques vary depending on how many bulbs are present. Persistence is key. Mowing prior to spraying may improve uptake by exposing more plant material for contact with herbicides.

Timing is important; postemergence treatments are more successful than preemergence applications, due to difficulties penetrating a thin wax layer.

With determination and hard work, combined with proper use of suggested herbicides, one can expect good results eliminating unwanted patches or clusters. This won’t harm other nearby vegetation, making them safe places again for families to enjoy outdoor activities.

Wild Onions Versus Wild Garlic – Similarities and Differences

Wild Onions Versus Wild Garlic – Similarities and Differences
Understanding the differences between wild onions and wild garlic is key for effectively eliminating them from your landscape. Wild onion weed has thin, waxy leaves with white bulbs that spread by forming bulblets or seed, while wild garlic have winter perennials with underground bulbs. The main plant of a strong garlic smell will also produce three different types of undergrounds whereas the hollow-leafed onion does not.

Prevention measures such as mowing can weaken and prevent bulb formation for both plants, but it’s important to remember that chemical control is more effective when applied in fall and spring over two years due to their seasonal dormancy cycle.

Natural predators are ineffective against these weeds; however, mechanical control like pulling small infestations out when soil is moist, or using pre-emergence herbicides, can be used as an alternative form of elimination if done correctly.

Controlling Wild Onion/garlic – What You Should Not Do

Controlling Wild Onion/garlic – What You Should Not Do

Don’t be fooled; you can’t just sweep wild onion/garlic under the rug – it takes a lot of elbow grease to get rid of them!
To ensure success, there are certain preventative measures and natural remedies that should not be adopted.
Pre-emergence herbicides won’t have an effect on these weeds, so don’t apply them.
Mowing weakens the plant’s roots and prevents bulblets from forming, but won’t kill off entire plants like chemical control would.
Soil amendments such as composting or shaking excess dirt off should be avoided too, as it’ll only spread more bulblets in your lawn or garden area.

Effective chemical control requires persistence over multiple seasons, and must be timed correctly during fall and early spring periods when temperatures are still lower than 60°F.
Don’t waste time trying ineffective methods – invest in some good old fashioned hard work combined with proper herbicide use for optimal results!

Best Methods to Control Wild Onions/garlic

Best Methods to Control Wild Onions/garlic
Controlling wild onions and garlic can be difficult. Postemergence herbicide treatment is key. Their thin waxy covering makes it hard to achieve successful control. To ensure success, spray plants more than once and for more than one season. Mowing immediately before application may help uptake. Timing is crucial; treat in fall and early spring for best results.

Postemergence Herbicide Treatment With Persistence is Key

To effectively control wild onion/garlic, persistently applying postemergence herbicide treatments during fall and early spring when temperatures are lower than 60F is key. Hand pulling risks leaving parts of the bulb behind, while herbicide safety depends heavily on accurate selection and application as turf damage is common with some commercial products.

When selecting a postemergence herbicides to use against wild onion/garlic, consider its active ingredient(s) for best results – 2,4-D or mecoprop in combination with dicamba can be effective in both fescue and warm season lawns u2013 along with non-ionic surfactants, which help improve adherence and penetration but may cause temporary yellowing of grasses.

Persistence is key; multiple sprays over several seasons may be necessary for complete control. So, monitor effectiveness closely every fall & spring to ensure retreatment happens at the right times if needed.

Thin, Waxy Covering on Leaves Makes Herbicide Control Difficult

You may have difficulty with herbicide control due to the thin, waxy covering on wild onion/garlic leaves. But persistence is key for successful elimination! Prevention measures such as wearing gloves and applying mulch can help. Also look into alternative solutions like biological control or mechanical damage during the cool parts of the year when growth slows down.

When using herbicides, make sure to use a non-ionic surfactant that will improve adherence and penetration, while not causing temporary yellowing of turfgrass. Also, mow immediately before application to optimize uptake and prevent white stalks from emerging again later on in the season.

With all these methods combined, you can expect effective results over multiple seasons if done properly. Just remember, persistence is key!

Spray Plants More Than Once and for More Than One Season

For optimum success, you should spray your wild onion/garlic plants more than once and for multiple seasons – it’s worth the effort!

Non selective herbicides can be used in early spring and late spring. Three-way broadleaf herbicides containing 2,4-D, dicamba and mecoprop are a great option for control in both fescue and warm season lawns. You could also use glyphosate as a nonselective herbicide to effectively control wild garlic or other weeds in areas that are not turfgrass.

To get the best results from these products, add a Non-ionic surfactant. This will aid with adherence of the products on thin waxy leaves of these weeds, making them easier to target with sprays. Late fall applications may also help improve overall effectiveness when paired with cultural practices such as mulch layers or soil nutrition amendments including beneficial bacteria.

Mowing Immediately Before Herbicide Application May Improve Uptake

You can maximize herbicide effectiveness and control wild onion/garlic more effectively by mowing the area just before application. Don’t miss an opportunity to make a real difference! Applying frequency, plant stress, and timing of application are all factors to consider when applying herbicides. Weather conditions also play a role in weed competition response to treatment.

Mowing immediately prior helps create optimal conditions for increased uptake of the herbicide onto thin waxy leaves. This is especially true with wild onions, which have thinner waxy leaves than other weeds, making them harder to treat with standard postemergence products alone without help from mowing right before each new round of applications.

With some determination and hard work you can expect success in eliminating these pesky invaders from your lawn or garden beds!

Timing of Sprays Crucial; Treat in Fall and Early Spring

To successfully control wild onions and garlic, time your sprays correctly – treat them in the fall and early spring for best results. Natural control such as mulching or biological methods can be used but may not provide effective long-term control. Pre emergent sprays are better for prevention than eradication. Manual weed removal is labor intensive but simple for small infestations. Vinegar or herbicides may be applied for larger areas – aim for late fall through early spring. Broadleaf herbicides like 2,4-D dicamba mecoprop or metsulfuron containing products, like Scotts Spot Weed Control & Weed Control Granules For Southern Lawns, effectively target wild onion/garlic plants and don’t harm grasses during this period. This is an ideal solution that will help reduce the spread of these weeds over time.

How to Get Rid of Wild Onions Without Damaging Your Lawn

How to Get Rid of Wild Onions Without Damaging Your Lawn
Removing wild onions from your lawn without harming the grass can be done with a combination of methods, such as using herbicides or physically pulling them out. Organic control includes natural remedies and alternative solutions that don’t involve chemicals. Vinegar is an effective way to kill green onions but it isn’t recommended for use on larger infestations.

Another organic solution involves digging up the bulbs manually, although this takes time and effort if there are many plants. Chemical solutions include three-way broadleaf herbicides containing 2,4-D, dicamba and mecoprop which provide excellent results when used over two years in fall and spring applications; however a non-ionic surfactant such as Southern Ag Surfactant may be needed to improve control effectiveness.

Products like Scotts Spot Weed Control or Weed Control Granules for Southern Lawns that contain Metsulfuron can also help get rid of wild onion problem areas in lawns while preventing further growth by eliminating bulblets production at the same time.

Prevention strategies should also be considered including regular mowing before weed emergence to prevent bulb formation since preemergence herbicides can’t protect against them; additionally removing stems quickly when soil moisture is high will minimize spread efficiently too.

To ensure complete removal of these weeds it’s important to keep monitoring treated areas throughout fall/spring season until no more signs are present, so reapplication may be necessary if desired result isn’t achieved.

Transitioning into Wild Onions Versus Wild Garlic – Similarities and Differences section reveals some interesting facts about both types of weeds regarding their management programs required.

Broad leaf weed killers containing 2,4-D, dicamba, and mecoprop can also work if applied correctly.

Now you know what to do. Just remember timing is everything!

Is Wild Onions / Garlic Edible?

Wild onions or garlic can be edible – if they haven’t been treated with chemical herbicides. To keep them as edible, trim them regularly. Control requires a combination of methods, including manual removal and postemergence herbicide treatments in fall and spring, over several years, for consistent results.

Edible if Not Treated With Chemical Herbicide

You can safely consume wild onion and garlic if you opt out of chemical herbicides. Weed pulling is essential for small infestations and soil prep with mulching or interplanting is an organic control option. Use a large dose of vinegar or death camus on hollow leaves in warm-season lawns or veg gardens respectively. Mow immediately before herbicide application to improve uptake. Use non-ionic surfactant such as Southern Ag Surfactant for Herbicides to increase effectiveness, although it’ll temporarily cause turfgrass yellowing.

Follow these steps and you can consume wild onion and garlic without chemical treatment.

Keep Trimmed if Keeping as Edible

If you plan to keep wild onion and garlic as an edible crop, be sure to trim them regularly for optimal results. Preventative measures are a must since wild onions’ pungent smell can attract animals that could damage your garden. Identifying the species of onions or garlic in your yard will help you find natural solutions or uses such as cooking with them. Preparing the soil prior to planting will encourage smaller bulbs and fewer weeds, making it easier to maintain during the growth period.

Regularly trimming both onion and garlic plants helps reduce their odor while encouraging new sprouts from the underground bulbs. This allows repeat applications of three-way broadleaf herbicides on St Augustinegrass lawns without worrying about damaging a large clump all at once, which would take longer to control without direct contact with each bulb’s thin waxy covering leaves.

Trimming also prevents overcrowding, promoting healthier plant growth. It allows more nutrients into the soil through adequate air circulation around the roots systems, resulting in larger yields per harvest when done properly over time.

Do Wild Onions or Wild Garlic Cause Any Problems in My Lawn?

You may experience problems in your lawn due to wild onions or garlic, so it’s important to take steps for their control. They can spread by forming bulblets on bulbs or by seed, so prevention and containment are key. Natural alternatives such as avoiding overgrowth and mowing regularly might help, but won’t always work for killing them safely. Treating the area with non-selective herbicides or boiling water will kill existing growth. Controlling further growth requires a combination of methods, including preemergence herbicides with good spray coverage on plant tissue. Thin, waxy leaves make herbicide application difficult, so timing sprays correctly and multiple applications over two years may be necessary for consistent results in preventing infestations from coming back.

Frequently Asked Questions (FAQs)

What is the best time of year to remove wild onions?

Mulching strategies, alternative removal methods and soil preparation are important steps to consider when looking for the best time of year to remove wild onions. Spring is often seen as ideal due to the environmental impact, but fall can be just as effective if done properly. Fertilizing prior to removing thick lawns helps create a better environment for future wild onion prevention; however, warm-season turfgrasses shouldn’t be treated with herbicides during this time. Postemergence treatments in late summer or early fall work well on perennial bulbs like those found in wild onions since it provides consistent results over two years—persistence being key! Mowing doesn’t kill the plant but can weaken it and prevent bulblets from forming, so timing your treatment is crucial.

Is it safe to compost wild onions?

When dealing with wild onions in the garden or lawn, it’s not safe to compost them due to their ability to spread quickly. The best method for removal is manually removing clumps of them, either using a spade or trowel in spring or fall.

But thin waxy leaves make herbicide application difficult. Pay attention to product instructions for use on homeowner products, available at gardening centers and home improvement stores.

Are wild onions and wild garlic the same?

Wild onions and wild garlic may look similar, but they aren’t the same plant. Wild onions have thin, waxy spear-like leaves with white bulbs, while wild garlic has underground bulbs that go dormant in summer and regrow in fall/spring.

To prevent or get rid of these pesky plants, there are a large selection of native plant options, as well as chemical and nonchemical control methods available. These range from herbicides to boiling water or manual removal.

The main question comes down to how much hard work you’re willing to put in. If your answer’s ‘not much’, chemical controls may be right for you. But if your determination’s high, natural remedies can do the trick too!

For best results, keep an eye on the area after following any spring treatments when average daily temperatures exceed 60°F for optimal effectiveness.

Are there any natural remedies to get rid of wild onions?

If you’re looking for natural alternatives to get rid of wild onions, there are a few organic solutions that may be effective. Mowing immediately before applying herbicide can improve uptake and using boiling water is the most effective organic way to kill them.

It’s important to remember that treating with non-selective herbicides or pulling out clumps in the spring or fall will give you the best results. As wild onions have thin, waxy leaves which give them a lot of surface area, it might take multiple treatments with persistence over two years for successful control – so don’t forget an important tip: keep monitoring and repeating your treatment if needed!

Are there any methods to prevent wild onions from coming back?

It can be difficult to keep wild onions from coming back after removing them. However, there are several methods you can use that will help prevent regrowth. Mulching and shallow tilling at the beginning of spring is a good way to reduce any new growth. Overseeding with grass or growing cover crops may also help, as well as core aeration if your lawn has centipede grass.

Small surface area lots of herbicides such as 2-4-D could be used for treating wild onion infestations in lawns. The Illustrated Flora of the Northern United States suggests you shouldn’t apply these chemicals without first consulting an expert on weed control, so they don’t damage other plants in your garden or landscape.


Apply herbicides at the right time and use non-selective herbicides in non-turf areas to get rid of wild onions and garlic. With persistence and the right herbicides, 90% of lawns treated with three-way broadleaf herbicides containing 2,4-D, dicamba, and mecoprop showed successful control.

Keep your lawn healthy and wild onion-free with these tips.
