Blueberry plants are slow-growing plants. They may not change much in size till they reach full maturity. They’re best grown in full sun and soils with acidic pH, usually between 4.5 to 5.5.

Note that you must avoid growing them in compact soils, as they prefer loose, well-draining soils that are rich in nutrients and organic matter.
