Simply add an inch or two to the top of the soil. For a quick fix, water plants several times with a solution of 2 degrees of vinegar to a gallon of water. It’s a great way to adjust the pH in the soil.

What is a good acid fertilizer for blueberries?
The best way to make the soil acidic is with ammonium sulfate. The amount of initial application depends on how acidic your soil is. To maintain an established pH level, 2 to 4 ounces per bush per year is adequate. However, if you have a very acidic soil, you may need to increase the amount of ammonium sulphate applied.
When should I acidify my soil for blueberries?
Pure sulfur, or a commercial soil acidifier containing sulfur, is the most common treatment used to acidify soil for blueberries. If you do this the year before you plant your berries, the sulfur will be able to do its job before the berries start ripening. Sulfur can also be added to the soil at the time of planting, but this is not recommended because it can interfere with the ripening process.
If you choose to add sulfur at planting time, make sure it’s not too strong, as too much sulfur can be harmful to your plants. The best way to use sulfur is to mix it into your soil and let it sit for a few days before using it. This will allow it to break down and release its sulfur content.
How do you lower the pH of blueberries?
Adding sulfur will lower the soil pH. It is possible to till sulfur into the soil down to eight inches. This depth is enough for the roots to grow. Each pound of sulfur will be lowered by one point for every twenty-five square feet of soil. Sulfur can also be used to fertilize blueberries.
You can add 1/2 teaspoon of sulfur to a gallon of water and add a few drops of fertilizer at the same time. If you are using a fertilizer that contains sulfur, be sure to read the label to make sure it is compatible with your soil and that it will not harm your plants.
Is Epsom salt good for blueberries?
The most common symptom of a magnesium deficiency is mature leaves that are pink on the edges and yellow between the veins. When magnesium is low, based on a soil test, you can add Epsom salts (magnesium sulfate) at the rate of 3 ounces per 1,000 square feet of soil.
Magnesium deficiency can be caused by a number of factors, including a lack of magnesium in the soil, a deficiency of other minerals, or a combination of both. If you suspect that you may be deficient in magnesium, consult your health care provider.
Is coffee grounds good for blueberries?
Coffee grounds are acidic so they should be reserved for plants like azaleas and blueberries. Coffee grounds could stunt the growth of plants that need it the most if your soil is already high in nitrogen. “If you’re growing a lot of nitrogen-fixing plants, you might want to consider using a coffee ground instead of a nitrogen fertilizer,” Coffey .
How do you increase the yield of blueberries?
It’s a good idea to always plant blueberries in a sunny spot. Full sun (6 hours or more of direct sunlight per day) is required to grow blueberries. If plants are planted in shade, they will grow slower and produce less fruit.
