Blueberry plants will gradually spread from their growing location through a process called suckering. New, fast-growing shoots grow out of the soil from the main root cluster a few inches from the main clump. Over time, the size of the blueberry bush grows gradually as new suckers form.
Where is the best place to plant blueberry bushes?
Select a sunny, sheltered spot. While blueberries are tolerant of shade, better crops are obtained in the sun. At the same time, they should not be exposed to harsh, drying winds. Don't plant blueberries too close to trees, as the trees will not only block out sunlight, but will also suck up any moisture in the soil.
Are blueberry roots invasive?
Blueberry roots are shallow, generally penetrating no deeper than 10 inches, so a garden bed tilled to a foot deep works in well-draining soil.
