The United States is the world’s largest producer of blueberries. They
are also grown in Chile, Argentina, Colombia, and British Columbia.
Blueberries
have very specific soil requirements. Plants grow best in well‑drained,
light, sandy loam soils with organic matter content greater than 3% and
have a pH between 4.5 and 5.5.
When the pH is outside the
optimum range for growing blueberry plants acidifying materials will be
needed to lower soil pH. Nitrogen and ammonium sulfate fertilizers are
used to increase soil acidity. Preparing a site for planting may take
several years.
Avoid planting on heavy soils that drain slowly.
Soils with a clay or silt content greater than 20% are not favorable for
growing blueberries. Blueberry plants have a shallow root system and
need good drainage to thrive. Water standing on the soil surface for
more than 2 days during the growing season can damage roots. The soil
water table should be at least 14 inches below the soil surface, or
roots will suffocate.
The highbush blueberry (Vaccinium corymbosum and Vaccinium australe)
range in height from 1.5 to 7 m (5 to 23 ft) and like sunny, acidic
areas with a pH between 4 and 5. These blueberries are shallow-rooted
plants and are characterized by the lack of root hairs. These fines,
fibrous roots require an open, porous soil for ease of growth.
