Benefits of vinegar for plants

Since time immemorial, people have used vinegar for so many different purposes. In fact, our grandmothers were among the first generation to talk about its benefits on both indoor and outdoor plants. Next, we’re going to tell you in detail about the most outstanding ones. Take note!

Use the white vinegar.
Vinegar has many benefits for both indoor and outdoor plants.

1. Vinegar prevents mold on plants

Vinegar has antifungal properties, making it the ideal ally for preventing and controlling mold on indoor and outdoor plants. This liquid contains acetic, tartaric, and citric acid. It’s thanks to this that you can eliminate mold, which threatens the well-being of all your plants.

To use it, dilute two tablespoons of vinegar in a container with three liters of water. Shake the mixture and place it in a spray bottle. Then, simply spray any plants that are at risk.

2. Benefits of vinegar for plants: enriching the substrate

Use vinegar to add a little iron to the substrate or soil where your plants grow. To do this, simply pour some pure vinegar directly onto the soil.

However, you must be careful because an excess of neat vinegar can actually damage your plants. Remember, some plants won’t develop or perform well in acidic soils.

3. Vinegar can contribute to germination

When you’ve planted new seeds, use a little vinegar to soften the outer shell. This will encourage germination and it’s easy to do.

Add water to a bowl and mix around five to eight drops of white vinegar.  Then, add the seeds and let them soak overnight. After you’ve planted them, you’ll notice that they germinate faster. Equally, they’ll be healthier too!

4. Vinegar regulates pH balance

Being an acidic liquid, vinegar helps to regulate the soil pH and provides them with well-being and more potential for healthy growth.

To do this, add a tablespoon of vinegar to a liter of water and pour it directly into the plant pots or onto the soil. Acidophilic plants such as hydrangeas and gardenias will benefit the most from this mixture. This is because as their name suggests, they need acidic substrates to grow.

5. Use vinegar to clean vases and plant pots too!

One of the benefits of vinegar is that it keeps vases clean.

Glass vases and pots are often affected by the lime that’s present in water. This causes them to develop annoying white lines or watermarks that are quite ugly.

To solve this issue, take a clean cloth and sprinkle a few drops of vinegar on it. Then use the cloth to wipe over the white marks and you’ll soon see how they disappear with ease.  As you can see, it’s not only plants who can enjoy the benefits of vinegar.

6. Use vinegar to make your flowers last longer

Considering that vinegar has extensive benefits for your plants when you use it on cut flowers, it’ll help to make them last longer and flourish.

This product will keep pests, bacteria, and other harmful organisms away. If you want to make it really effective, mix two tablespoons of white vinegar with one tablespoon of sugar in a container of water. Add the mixture to the vase and enjoy your flowers for even longer!

7. Vinegar is a great herbicide

Among the most outstanding benefits of vinegar are its herbicide, fungicide, and repellent abilities. It’s renowned for eliminating the insects that plague plants 

Use one part vinegar to two parts water and spray the leaves of your plants to keep them pest-free. How often you use it, will depend on the level of infestation.

8. Keep pets away from your plants

The relationship between pets and plants is often contentious. The ideal situation is that pets and plants live in harmony without pets digging them up!

Vinegar will be your best ally if this situation is familiar. Soak a couple of cloths in vinegar and leave them near your plants, pots, and soil. You’ll soon notice how dogs and cats will avoid them. This means that your plants will be safe and you’ll keep calm!
