Blueberry (Highbush)

Highbush blueberries require acidic soil and careful drainage management. They are less drought and heat resistant than rabbiteye blueberries.

Vaccinium corymbosum · Deciduous perennial berry shrub

Profile

Soil: Acidic soil with incorporated organic matter is important.
Drainage: Avoid low sites where water collects; raised planting rows can improve drainage.
Light: Full sun supports maximum yield.
Establishment: Remove flower buds from young plants to favor establishment.

Water & soil context

Moisture (VWC): Maintain moisture throughout the root zone while avoiding saturation around the crown.
Salinity tolerance: A salt-sensitivity class or threshold is not documented in the cited pages.
Drought tolerance: Less drought resistant than rabbiteye blueberry.

Editorial placement example, not a validated optimum or total rooting depth. Confirm the site's root distribution and soil horizons; multiple depths may be needed.

Irrigation is particularly important during the planting year, but frequent watering that keeps roots wet can encourage root rot.
