Choose a healthy blueberry plant suited to your region.
Prepare soil before planting.
Plant in a sunny position.

For growing blueberries in pots NZ gardeners should focus on:
Choosing a large container.
Using suitable growing media.
Maintaining moisture.
Providing regular nutrition.
Container-grown blueberries can be very productive when their soil environment is managed correctly.
Feeding Blueberries for Better Fruit Production
