Using Vinegar to Acidify Soil for Blueberries

If you’re not familiar with it yet, vinegar is a diluted and liquid form of acetic acid. When you add it to the soil, it would naturally lower its pH level, increasing its acidity. That’s why it’s very helpful when planting blueberries, as the plant requires more acidic soil.

Furthermore, vinegar contains certain vitamins useful for plant growth, depending on the type of vinegar, where it’s made from, and how it was processed. You can opt for commercially manufactured white vinegar, or when organic gardening, opt for organically made vinegar.

When using vinegar to acidify soil for blueberries, you can apply it using an irrigation system, or by hand. Start with two tablespoons of vinegar with one gallon of water, watering your blueberry bush with this mixture once a week or so. You may also use an injector for even distribution, though this is totally up to you and your preference.

Do NOT add vinegar directly to your soil or blueberry bush, as it has pH levels between 2.3-3.4, which can cause root burn or other injuries to the bushes.

Furthermore, make sure that you use the right type of vinegar to enrich your soil without affecting nearby plants, as well as limit the chances of accidental injury to pets and wildlife, as well as the blueberries. I recommend using culinary vinegar, particularly apple cider or white vinegar. Do NOT use horticultural vinegar, as this is used as an herbicide, and adding too much can damage blueberries while posing a risk to humans, plants, and animals.

With all this in mind, take note that this is only a quick fix and not a long-term solution to lower your blueberry bush’s soil pH levels. Other ways to lower your soil’s pH levels for blueberries are by adding sphagnum peat or used coffee grounds around your blueberry plant base yearly. You can also fertilize blueberries with acidic fertilizers or sulfur.

Before You Do This

Regardless of whether you’re planting new blueberry bushes or improving your existing bushes’ growth and development, you need to test your soil. This is so you know what work your soil needs for better blueberry growth.

Take note that the proper soil pH levels for growing blueberries are between 4-5, which is going to the acidic level. When you have already applied the vinegar solution, be sure to check the soil’s pH levels after a few days and watch out for signs of stress on your plants, such as yellow or drooping leaves.

If the vinegar solution goes below 5, discontinue applying vinegar and start flushing your soil using fresh water for a neutral pH level. While blueberries thrive in more acidic soil levels, too much of it can harm them in the long run.

Wrapping It Up

While vinegar is an effective way of balancing your soil’s pH levels, you have to be careful with it! Make sure that you double-check your soil’s pH levels and try vinegar with a small amount, mixing it with water to ensure that you won’t throw off its quality. That way, your blueberries can thrive in its environment, provided that you combine soil quality with proper care and maintenance.

I hope that this article on using vinegar to acidify soil for blueberries helped you out! So don’t wait any longer and make sure to check your soil’s pH levels to find the appropriate solution for it to ensure your blueberries grow well.

  1. We need a soil mix with a PH of 4.5, I can’t figure out why they don’t. It’s a much needed product and would simplify growing acid loving plants. Someone please help..

  2. I was told to use Ericaceous soil which is the right PH for acid soil loving plants like blueberries, and to only use rainwater. Unfortunately my water butts are empty so I might try the above advice. Thanks
