my blueberry bushes just arent growing!! ive have them for 5 years, and theyve only grown in the order of 4 inches!
Answers:    The biggest problem with blueberries is have the right pH in the soil. Blueberries love soaring acid soil so thepH is best between 4.0 and 4.5 They also prefer a sandy loam fairly than clay. So correct acidic PH and drainage are probably your problems.
Some are dwarf bushes,and willnot grow extraordinarily high. Have they be producing? If they have, leave your job them alone
