That means that before planting new blueberry plants, you must check your soil pH and then amend it prior to planting your blueberries. This article outlines how to do that. Blueberry soil requirements Blueberries require the soil to have a pH between 4.3 to 5.5 pH . This is unique, because most fruit and vegetable plants do best in a relatively neutral pH soil between about 6.5-7.5. Growing blueberries between 6.5-7.5 would cause them to have slow, weak growth, yellowish leaves, and little to no fruit. Reducing the pH prior to planting and keeping it low for the lifespan of the plants, will help ensure strong fruit yields and healthy plants. The pH is amended by adding sulfur to the soil in the form of sphagnum peat moss, elemental sulfur, or another widely available sulfur amendment found at garden
