People have been using vinegar in their gardens for centuries. Vinegar is safe to use around your plants, fish, and wildlife. It’s non-toxic to humans, but it can kill beneficial insects and certain soil organisms. Vinegar is acidic, though the strength of its acidity varies depending on the type of vinegar used. 

There are several reasons to use vinegar in your garden. Let’s take a look at some of the most common reasons people use vinegar for growing plants. 

  • Boosts Plant Growth – The most common reason for using vinegar in the garden is to boost plant growth and increase crop yields. Vinegar is a great source of nutrients like nitrogen, phosphorus, and potassium. 
  • Improves Soil Structure – The acidic properties of vinegar help improve soil structure. It can help break down clay soils and loosen hard, compacted soil. It can also help sandy soils retain nutrients and moisture. 
  • Kills Off Weeds and Vinegar-reliant Insects – Vinegar is an effective herbicide that can kill weeds and their roots. It also kills off certain insects that rely on vinegar for food. 
  • Improves Plant Health – In addition to growing bigger and producing more, plants benefit from healthier root systems. A healthy root system means fewer weeds, fewer diseases, and less chance of dying. 
  • Organic Fertilizer – Vinegar is an organic fertilizer that is completely safe for people, animals, and the environment.

Is it Bad for the Soil?

Vinegar has been used for centuries as both an herbicide and fertilizer. Though it can be bad for certain soil organisms, it’s great for your plants! Vinegar is an acid, which means it has a lower pH level than most soil amendments. 

Soil pH is the level of alkalinity or acidity. A pH level of 7 is neutral, with anything below 7 being acidic and anything above 7 being alkaline. While vinegar is acidic, it can actually improve soil pH over time. 

This is because the vinegar breaks down into acetic acid, which is more alkaline than vinegar. By improving soil pH and adding nutrients like phosphorus, vinegar is a great option for use in your garden.

How Long Does Vinegar Last in Soil?

Vinegar lasts anywhere from a few days to just under a month in soil. This all depends on the type of vinegar used. White vinegar has a pH of about 5.1 and lasts up to 30 days in soil. Apple cider vinegar falls in between, with a pH of 4.5. It can last between 21 and 30 days. 

Balsamic vinegar has a slightly higher pH of 4.8, and it can last up to 25 days in soil. Because vinegar has a short lifespan in soil, it’s best to apply it as a top dressing. Soil tends to be acidic, but you can test your soil to see if it needs additional acidity. Simply take a sample, send it off to a lab for testing, and get the results back.

Can You Grow Plants with Vinegar?

Vinegar is an excellent choice for growing plants! It’s an organic fertilizer that is safe for people and animals, and it can help improve soil structure. If you’re growing plants indoors, especially ornamental plants like philodendrons and ferns, you can use vinegar as a fertilizer. 

It’s safe to use with any type of plant, and it can help improve soil structure and plant growth. If you’re growing your plants outdoors, you can use vinegar as a soil amendment. It can help break down clay soils and improve sandy soils, as well as add nutrients. 

Simply mix one part vinegar with five parts water and spray your plants twice a month during their growing season. Make sure to thoroughly saturate both the soil and the leaves of your plants.

Bottom Line

Vinegar is an excellent tool for growing plants and improving soil structure. It’s safe for people and pets, and it’s easy to apply. You can also use it to control weeds and other pests that rely on vinegar as food. Vinegar lasts in soil for about a month, so you’ll want to reapply it often. 

You can also use it as a top dressing for ornamental plants indoors or as a soil amendment for outdoor plants. It’s an effective way to improve soil health and keep your plants thriving!
