Vinegar is a contact herbicide, so you can unintentionally kill plants in your garden if you accidentally spray them with vinegar. Using vinegar as a weed killer works best on newer plants. "On more established plants, the roots may have enough energy to come back even if the leaves you sprayed have died.
Acidity: Vinegar is acidic (typically 5-20% acetic acid), which can damage plant tissues, especially if applied directly to the leaves or stems. This can lead to burning, wilting, or even death of the plant.
Vinegar is fatal to plant life. It is acidic and thus dissolves the cell membranes of leaves. This leads to the desiccation of plant tissues and ultimately results in plant death. When introduced into the soil, it lowers the pH level and inhibits plant growth.
Although vinegar is non-selective, species differ in their susceptibility to vinegar. For example, broadleaf plants tend to be more easily controlled with vinegar than grasses. Also, some broadleaf plants are more susceptible than others because of their morphology.
Even though vinegar is an acid, it breaks down quickly in the soil and, therefore, is not likely to accumulate enough to affect soil pH for more than a few days. Vinegar causes a rapid burn to plant tissue of susceptible species, so unintended injury is quite likely without knowing more information.
Vinegar is acidic and will eventually kill most broadleaf weeds, but the acid will kill the leaves before reaching the root system, and the weeds may grow back quickly.
Watering with vinegar is not a recommended method for lowering soil pH for a couple of reasons. First, you would need a large amount of vinegar to move the pH of a large garden bed from 7.5 to 7.0 and because you would not want to apply vinegar to the soil without diluting with water, this could take a while.
Generally, vinegar is categorized as a natural or organic weed killer. So, it lures many people to believe its use is safe. However, the opposite is true as it is a corrosive substance. It is acetic acid (the chemical that kills weeds).
Prevent Fungal Disease
MAKE IT: Mix 1 teaspoon of baking soda and 2-3 drops of liquid soap in 1 liter of water. Spray the solution on the infected plants. Baking soda helps the plants become less acidic and prevents fungal growth.
Specifically, aphids and fruit flies love the scent of vinegar and will seek it out. You can use this to your advantage by creating traps. Mixing a quart of water, 12 ounces of vinegar, and a tablespoon of dish soap, you can create a mixture that will rid your garden of annoying, buzzing pests.
Vinegar is a contact herbicide, which means it kills the part of the plant it comes into contact with. Systemic herbicides, on the other hand, are taken up by the plant's vascular system and delivered to roots, eventually killing the whole plant instead of just its top growth.
There are almost countless uses for cinnamon in the garden: it can be used as a nature-friendly pesticide, a repellent against annoying insects, or as a catalyst to promote root growth in plant cuttings.
Mixing vinegar and baking soda causes an immediate chemical reaction. This reaction forms water, sodium acetate (a salt) and carbon dioxide – the fizzy part. The amount of carbon dioxide gas that is produced from baking soda is remarkable – one tablespoon (around 18 grams) can release over five litres of gas!
Saturate the soil with 1/2 cup hydrogen peroxide 3% per 1 litre water. Put wet soil in a watertight container and leave overnight before planting. This kills pathogens such as fungi and bacteria including insect eggs and nematodes (roundworms).
One of the single best uses for unfinished opened beer is as a compost pile jump starter. The sugars and yeast in beer are excellent for your compost pile. Simply pour it over your compost pile and then stir or turn it when required. Beer can be used as an effective fungicide for your plants.
Are coffee grounds good for plants? Coffee grounds are an excellent compost ingredient and are fine to apply directly onto the soil around most garden plants if used with care and moderation. Coffee grounds contain nutrients that plants use for growth.
Aside from the anecdotal evidence about human benefits, Epsom salt does seem to help plants. Generations of gardeners have said it helps their plants grow bushier, produce more flowers and have better color. It's also said to help seeds germinate and repel slugs and other garden pests.
Permanently kills only broadleaf weeds; grasses and perennials grow back. Only kills above-ground growth, root systems are unaffected.

Maintaining Your Garden
Combine 1 cup (240 mL) of white vinegar and 4 litres (17 c) of cool water together in a watering can or jug. Next, stir both ingredients together using a long utensil. Pour the mixture over your plant beds to lower the pH, which can help certain plants (e.g., azaleas, rhododendrons) to thrive.
Use ACV for fertilising your plants
As a result of our ACVs low acidic content, it's great to use as a fertiliser. Using organic, raw and unfiltered ACV, such as Willy's, is great for your plants due to it containing pulp which has the highest amount of nutrients for your plants!
