Will Vinegar Kill Your Plants?
Vinegar will kill your plants if you are not careful. Vinegar, like many other weed killers we use, is non-selective. This means that it will and can kill any plant matter it comes into contact with, as it cannot tell the difference between what we perceive to be a weed and a desirable plant.
Vinegar contains a compound called acetic acid that dissolves the cell membranes of plants. This results in the desiccation of the plants’ tissues and will ultimately kill them.
If you decide to use a vinegar solution as a weed killer for your garden, we highly suggest you don’t use it on weeds found in your lawn.
If you do, you will end up with unsightly withered brown patches.
If you are using a vinegar-based weed killer, it’s best to use it in areas such as walkways and patios where weeds tend to be isolated and are set away from garden plants you want to thrive.
For weeds that are surrounded by annual or perennial plants that you really don’t want to kill, we suggest good old-fashioned digging and pulling as your de-weeding method of choice.
Sometimes, the more physical deseeding options are still the best.
How To Safely Use Vinegar To Kill Stinging Nettles Only
The best thing about using homemade vinegar solutions to kill weeds like stinging nettles is that they are relatively non-toxic to humans if you are using the type of vinegar you find in your kitchen cupboards.
For example, A curious toddler who gets some on their skin with have no adverse effects, and if they push that curiosity even further and try to ingest some.
Well, the worst that will happen is that they will be left with a rather awful taste in their mouth and possibly a little tummy ache if they ingest a good amount of it.
Although a vinegar-based weed killer is generally non-toxic to both humans and many pets, it’s still a solution you want to keep away from curious little people, and there are a few things you need to keep in mind if you want to use this vinegar-based solution safely.
It is strongly advised to only spray stinging nettles with your vinegar solution directly.
This will minimize the vinegar solution landing or absorbing into other plants or flowers you want to keep and retain.
Avoid Soil Contact
The salt in most vinegar-based weed killers is not great for our soil, and a build-up of salt in your soil will render it useless for any plant growth.
It will also take an incredibly long time for the salt levels to reduce and soil quality to improve to a level where plants will happily thrive again.
So it’s important when using this weed killer to ensure you are spraying the weed directly on its leaves and stem and avoiding the soil beneath it as much as possible.
Use On Non-Windy And Sunny, Dry Days
The drift of this weed killer can reach more than your intended weeds, so it’s important to use it on days where the wind is as minimal as possible.
This will ensure that the product you are spraying is landing directly on the weeds and not being blown into nearby beds and landscapes.
For this weed killer to be effective, you need to apply it when you have a few warm, dry days forecast.
This will give the solution the chance to work on killing the weeds without the risk of it being washed away before it has done its job properly.
Although a one-off exposure to this weed killer won’t be detrimental to your health, long-term skin exposure can cause irritation and, in some cases, allergic reactions.
Just like when you are handling other garden items like compost, fertilizer, etc., wearing gloves can help maintain minimal exposure over the long term.
Store In A Cool, Dry Place
Any unused vinegar-based weed killer should be stored in a tightly sealed container, kept in a cool, dry, and dark place.
Make sure any container storing weed killer is appropriately labeled and kept out of reach of children or pets.
How Long Does Vinegar Take To Kill Stinging Nettles?
