When applying the fertilizer, it should be between the soil and the mulch. From the base of the bush, simply detach the mulch then sprinkle the fertilizer.

When sprinkling the fertilizer, it should be done in an even layer such that from the base of the plants it is done in a circle. Note, the fertilizer does not get to any part of the blueberry bushes, not the crown not the stem. Afterward, water the plants. Different Fertilizers can come with different instructions. So follow instructions to know the right measurement when you use a different type of fertilizer.

One of the ways to provide blueberries with nitrogen is by applying used coffee grounds. Stop disposing of your grounds after use. After brewing, people usually dispose of the grounds in a bid to get rid of waste in the kitchen. Usually, farmers use coffee grounds on blueberries as fertilizers.

When coffee grounds are added to the soil it provides nitrogen to blueberries as well as other plants. When plants are short of nitrogen, the most natural way to boost the nitrogen content is through coffee grounds. However, it is important to strike a balance. Be careful with the number of coffee grounds you use. Too many coffee grounds can negatively affect the growth of blueberries. It could hinder growth.

Blueberries are plants that require acid and coffee grounds also increase the level of acid in the soil. So if you need to make a neutral soil acidic, simply add a little coffee grounds.

So, don’t forget to access and test the soil before acidifying. Only when it lacks acid should you remember to do the following:


Using Coffee grounds is one of the many ways to make the soil acidic. Once the soil lacks acid use coffee grounds. Spreading used coffee grounds on the soil will do the trick.

Sphagnum peat is also known as a great source of acid for plants. To make the soil acidic you only need to do an effortless job. Around the base of the blueberry plants is where you need to apply the sphagnum. And this should be done yearly. Just once in a year is what is needed.


Using a soil acidifier (commercial) that contains sulfur or using pure elemental sulfur can make the soil acidic. For the sulfur to have enough time to work its way into the soil, you should apply these a year before when you’ll plant the blueberries. Rainy spring and autumn is the best time to apply the treatment. The soil PH and the soil type is a determinants of the amount of treatment you’ll need.


Vinegar contains nutrients and vitamins that the soil needs. Although not all types of vinegar have these features. Get a white vinegar that’ll conform with the level of liquid that you’ll need to feed the soil. One of the many ways to use vinegar as an acidic treatment for soil is by diluting it.
