Caring for Container Blueberries Container blueberries require proper care to thrive and produce a bountiful harvest. Here's how to care for your blueberry bushes: Watering: Blueberries need consistent moisture, but they don't like waterlogged soil. Keep the soil evenly moist, especially during the growing season. Sunlight: Blueberries need plenty of sunlight, ideally around 6-8 hours of direct sunlight per day. Place your containers in a sunny spot or use grow lights if necessary.
