Taking a proper soil sample for blueberry planting will be one of the single most important steps in planning your blueberry project. For conventional planting, soil samples can be taken directly to most local County Farm Extension offices and the cost is minimal. However, if you choose to treat your farm organically, we recommend using services that will analyze your soil and make soil recommendations based on your sustainable goals. Here are some current companies that we highly recommend:

Both companies are very helpful in guiding you in collecting your samples and with any questions in filling out the soil submission form. Once you have received your reading along with it’s recommendations, your farm is ready for your blueberry plant soil preparation.
BASIC CONVENTIONAL-GROWING INFO:
Blueberry plants thrive best in soils that have a PH level between 4.5 and 5.5. While containerized blueberry plants can enjoy the perfect soil environment if the proper mix is used, we recommend soil samples first for any farm installations.
If the pH of the soil at your farm is too high, granulated sulfur can be used to adjust the pH. If your soil tests specific for growing blueberries it will tell you how much sulfur needs to be applied to your farm if your pH is too high. You have to be very careful applying sulfur to your farm; too much can harm or kill blueberry plants. Sulfur needs to be applied 60-90 days prior to planting your farm. Otherwise, only a very small amount can be applied around the plants at a time.
Peat Moss is generally a great pH for blueberries, so adding it to your soil is helpful. If you have a soil that has a lot of clay adding pine fines can help with acidity and drainage. You will occasionally want to check the pH of the soil in the area in which your blueberry plants are planted and adjust it as necessary.
It is extremely important you have the correct pH for any blueberry project, especially a blueberry farm. Here is a great article on soil preparation from the University of Kentucky along with other great information.
