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. Taking a proper soil sample for blueberry planting at your farm will be important. Soil Samples can be taken directly to most local County Farm Extension offices and the cost is minimal. Once you have received your reading along with it’s recommendations, your farm is ready for your blueberry plant soil preparation. You can also test your farm yourself with Luster Leaf 1612 Rapitest pH Soil Tester. However, for the most accurate testing it is best to take your soil to a local County Farm Extension office.
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 the perfect 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. Become familiar with your choice of a good organic publication or conventional publication as a handy reference.
There is another option that some farmers are going with called mineralization. We are currently doing experiments with it to see how blueberry bushes grow using the mineralization method. It consists of the belief that the ground needs several different types of minerals to allow for a healthy growing environment. For more on mineralization feel free to call Jeff or the office and we would be happy to help.
