Blueberry Greenhouse

Blueberry climate strategy is about protection and timing rather than tight control. The structure shelters high-value fruit from rain, hail and wind while allowing enough winter chilling for the variety to break dormancy correctly.

• Rain and hail protection over the fruiting canopy
• Chilling hours preserved for variety dormancy needs
• Passive ventilation sized for warm harvest periods
• Retractable or vented roof options to manage flowering timing
• Bumblebee or honeybee access planned into the vent strategy

Water chemistry is the single largest technical risk in a blueberry project. The crop is intolerant of high pH, alkalinity and sodium, so treatment must be engineered before the growing system is selected rather than added afterwards.

• Acid dosing to hold irrigation pH at 4.5 – 5.5
• Alkalinity and sodium analysis before system design
• Reverse osmosis where source water quality demands it
• Low feed EC 0.8 – 1.2 mS/cm with ammonium-based nitrogen
• Drip fertigation per pot with drainage monitoring

Protection secures the harvest window and fruit quality, which is where premium pricing sits. The trade-off is capital cost per hectare and a longer establishment period before full production.

Blueberry is intolerant of high pH and sodium. Acid dosing, filtration and, in some regions, reverse osmosis must be designed before the growing system is selected.
