Acetic acid, a component of household vinegar that makes up 5% of its composition, works well as an organic herbicide. Weeds are burned by the acetic acid, especially when vinegar is applied on sunny days. Pickling vinegar, which has a 9 percent acetic acid content and is stronger than regular vinegar in terms of killing weeds, is frequently utilized. Although vinegar is a powerful herbicide, it has no preference and kills any desired plants or weeds that come into touch with it, especially immature plants and weeds. In general, established plants, including trees, are unaffected by vinegar.
What causes young maple trees to die?
Chickweed, dandelions, shepherd’s purse, and ground ivy were already a hassle for gardeners, but this year might be even more difficult. To create place for vegetables, flowers, or even grass, many of them are being forced to uproot large areas of maple trees. Although they are just a few inches tall, the baby maple trees can be challenging to remove since they are such delicate tiny creatures. Stress is the cause of the Lilliputian woods that have grown across lawns and gardens.
The stress those trees experienced when they ran out of water a few years ago, not the stress you experience trying to figure out what to do with 10,000 tree seedlings per acre (a good estimate, by the way). In 2017, stress led to helicopters, which then resulted in small woods this spring. It’s fairly easy. Perhaps a justification is in order.
Like in 2012, Northern New York’s summer of 2016 featured some of the driest soil conditions ever recorded, and the trees felt it to the fullest. According to George Hudler, who just retired from Cornell’s Plant Pathology Department, trees experience widespread root loss during particularly dry summers, and it may take them two to three years of favorable conditions for them to recover from that stress.
Most trees in 2017 produced what is known as a distress crop, which resulted in many times the usual amount of seeds being produced. This appears to be an evolutionary reaction, an effort to preserve the species in the face of potentially fatal circumstances. For instance, you might have noticed that conifers have a dense cone crop. Red (soft) maples and sugar maples alike, as well as their infamous cousins the boxelders, produced “at a rate that would make Airbus and Bell envious, helicopter seeds. Of course, the main function of a maple helicopter is to fly. The winged seeds, or samaras as they are officially named, did exactly that, falling into every flower pot and crack in the sidewalk in addition to gardens and lawns. And there, they began to grow pretty well, doing a good job of saving their species from extinction but causing problems for gardens and lawns.
In northern hardwoods, no one had ever had a distress crop of that size prior to 2013, and we weren’t sure what effect infant forests would have on lawns. Many of us who live close to maple trees will find that the mini-forest occasionally partially shades the grass. Because of the persistent rain in the early spring of 2017, the maple crop may have been worse because few of the blossoms were pollinated. Without that, we would actually be lost in the woods.
It turns out that removing mini-maples from a lawn is simpler than doing the same for a garden. The turf-science experts at Cornell advise using a 3.5- to 4-inch mower setting because it reduces weed, pest, and disease issues and reduces or even completely eliminates the requirement for nitrogen fertilizer. To get rid of the maple, it would be wise to disregard the rule for one or two early cuttings “umbrella and allow the grasses to emerge from the forest’s cover.
Change back to the higher setting once the trees have been damaged by close mowing so that the grasses can provide shade for the forest. Do not raise the rate at which you apply a broadleaf herbicide to your lawn on an annual basis. Maple seedlings will be killed by a broadleaf weed-control product containing 2,4-D or dicamba just like any other weed.
A relatively new active ingredient called Iron HEDTA, a water-soluble version of iron that kills most broadleaf weeds, is available for individuals who choose a less harmful option. Currently, you might have to order it online, but the more queries about it that large garden centers receive, the more probable it is that they will carry it in the future. As with any pesticides, thoroughly read and abide by the label.
Since almost every plant you would want in a garden is a broadleaf plant, gardeners are unable to apply broadleaf herbicides. They are forced to pull by hand, which I have discovered occasionally requires a pair of pliers to grasp those little maple stems.
Another alternative could be to let the seedlings grow, and call the Department of Environmental Conservation to assist you design a forest-management strategy for generating maple toothpicks. Call your neighborhood Cornell Cooperative Extension office for more details on lawns and gardening.

How can you naturally kill saplings?
You can try digging up saplings that are in the lawn, but make sure you get the complete root base. You can get rid of these saplings, but you might need to reseed the lawn where the holes are. You can also try applying herbicide to saplings if they are too numerous or challenging to remove from the ground.
For saplings that are not suckers, Zodega advises using a herbicide formulated with triclopyr or glyphosate. Prior to application, you must first water the area heavily for one or two days. When ready, cut the saplings to the ground with a hatchet before applying the herbicide with a brush.
Use of salt is a more environmentally sound method of eliminating seedlings. Rock salt, water, and a drill bit of one inch or larger are all you need to kill saplings with salt, according to Bob Vila. Drill a hole through a sapling that has been cut down to the ground. Salt and water should be added to this (but not to the point where it is overflowing). Remember that salt can harm the parent tree, so be sure that this sapling is not a sucker.
How may maple seedlings be stopped?
Before you can take the aforementioned safeguards, you’ll need to take some extra efforts to remove any maple seedlings that have already sprouted in your lawn.
Always hiring professionals for the job is the simplest course of action. Simply seek for assistance from a landscaping business if you can afford it. If you don’t, these simple methods will assist you in finishing the task:
Pull the Seedlings Out by Hand
You should have little trouble hand-pulling the young maple seedlings out of the ground if they have just begun to sprout.
It will be simpler to take the seedlings from the damp soil if you thoroughly water the grass a day or two prior to working on them.
Dig Them up With a Shovel
Since maple seedlings grow quickly, as we previously indicated, it will be challenging to remove them with your hands if they have been there for a time.
Dig out the maple trees with a hoe or a shovel, making sure to remove all of the roots to stop them from regrowing.
The best last resort for seedlings that have been there for a while is to use a herbicide.
To apply the herbicides, just trim the sprouts at ground level and then spray the recently-cut stems. The poisons will be absorbed by the stems and finally kill the sprouts.
Does Roundup destroy saplings of maple trees?
Apply a herbicide with the component glyphosate if the maple tree seedlings are in an area with no other vegetation, such as a sidewalk or gravel area. Do not use glyphosate around desired plants or grass because it will kill all vegetation.
You risk damaging other plants if you use more herbicide than what is indicated on the bottle.
In the spring, maple trees produce a profusion of yellow flower flowers, which eventually fall off and are replaced by seeds. The maple seed’s top is covered in feathery wings, and as it falls to the ground, it spins in a spiral pattern. There’s a significant probability that if you have a maple tree, your yard has unwanted maple seedlings as well. Killing the seedlings stops them from becoming taller and obstructing sunlight from reaching the grass below.
Use a garden sprayer to apply a herbicide containing triclopyr amine or triclopyr ester to kill maples and other woody plants.
To diluted the herbicide to the amount advised by the bottle directions, add water to the garden sprayer.
Spray the leaves of the maple tree seedlings well with the garden sprayer until the herbicide solution starts to drip off them.
Every two to three weeks, check the ground for fresh maple tree seedlings that have emerged. As directed on the pesticide container, reapply the herbicide as necessary to the new seedlings.
How can I remove tree sprouts from my lawn?
Utilizing a herbicide like glyphosate is an additional remedy (sold at most plant nurseries). Just prune the budding tree and liberally spray the herbicide onto the already pruned root.
Tree sprouts should be easily eliminated by this, destroying them and preventing further growth. However, use caution when using this or any other sort of chemical-based herbicide as it may harm neighboring trees.
Following the application of herbicide to the sprout(s), keep a watchful eye on your yard for the following few days and weeks. The sprouts should start to get brittle and brown, which is a sign that they are perishing.
Apply more herbicide at the base if they are not changing color. They ought to perish as a result with a little effort, giving you authority over your yard once more.
How can I remove tree sprouts from my lawn?
- You must first thoroughly hydrate the soil surrounding the seedlings. Do this a day or two before you want to physically or chemically remove the seeds. Thoroughly and slowly water the area. With this form of preparation, the soil is easier to work with and more open to the herbicide’s effects. Here, moisture is advantageous.
- Whenever feasible, remove saplings. The shovel or hoe may be useful in this situation. The saplings’ root systems need to be removed. If it is impossible to use this optimal strategy, proceed to step 3.
- You may occasionally need to herbicide-spray the saplings’ foliage. Triclopyr and glyphosate might be suitable remedies for this. You don’t want to spray the plant so much that it starts to drip. Your healthy grass can be at danger if the herbicide starts to run down onto your lawn.
- Don’t go too long without visiting your seedling post. Watch the area. Keep an eye out for other seedlings to emerge so you may remove them or treat them with a herbicide.
Will vinegar harm young trees?
This strategy is for you if your tree roots and stumps have leaves sprouting out of them. The roots of the tree will die when the supply of oxygen, water, and nutrients is cut off, which is done by the leaves.
Spraying white vinegar on the leaves that are emerging from the stump or tree roots is another approach to try and get rid of tree roots. The presence of leaves at the tree roots indicates that the roots are still alive and will spread outward.
To do this, get a clean spray bottle and fill it with white vinegar that hasn’t been diluted. Apply the solution on the leaves, then apply it again. The tree roots can eventually be destroyed by thoroughly immersing the leaves in white vinegar together with any shoots that emerge from the tree roots.
When using this strategy, keep an eye on your tree roots and add more vinegar as needed. If you notice any additional leaves emerging, apply even more vinegar.
Vinegar can be used in large quantities to get rid of weeds and other undesirable plants in addition to tree roots.
How are maple seedlings killed under mulch?
It is obvious that the best strategy to control the spread of the maple helicopters is to physically remove the seeds. The Cooperative Extension System advises using a rake to collect maple seeds. Pulling maple tree sprouts by hand is very simple once they have started to develop, although it can take some time and become tiresome.
After the seeds have germinated, using herbicides like glyphosate can still be helpful, but be careful not to use it on any other plants or it will also kill them. It is also possible to repeatedly mow over maple seedlings from early spring until early fall; however, by then, the helicopters will have created a significant mess.
The cleanup of maple helicopter seed, however, can begin much sooner if the correct trees are chosen. Red maples (Acer rubrum), which grow in USDA zones 3 to 9, produce their seeds from female plants rather than male plants, claims the University of Maine. Similar to this, some plants never yield any seeds. The ‘Marmo’ maple (Acer x freemanii ‘Marmo’), which thrives in USDA zones 3 through 8, is one example that won’t produce maple tree sprouts from helicopters, according to the Chicago Botanic Garden.
Can tree sprouts be killed by Roundup?

Herbicide Roundup is used to eradicate weeds, grass, and any other unwelcome vegetation.
Because it is non-selective, it will kill any plant it is administered on, including trees.
Spraying roundup consequently close to trees may cause their death, particularly if they are young or simply seedlings.
The First Step
When roundup is sprayed close to trees, there is a risk, but large, mature trees barely notice any impacts.
One reason for this is that mature trees have hard, thick barks, which prevent herbicide from penetrating and damaging them.
How come there are so many maple seeds in 2022?
First off, the scientific name for this winged seed is samara, which describes a unique fruit made for vast distances away from the parent tree. Although certain elm and ash trees also generate samaras, the samaras from maple trees are the greatest at flying.
Healthy maple trees can skip a year in seed development, either as a result of insufficient pollination or an especially good growing season the previous year. The presence of an excessive number of samaras may indicate that the tree underwent some form of “stress” the previous year. By producing an abundance of seeds, the tree is ensuring the survival of the species should the stress persist and the particular tree perish.
