    Plant it, then water slowly until the whole root ball is soaked.

    Keep the soil evenly moist while new roots settle in.

    New growth starts. Feed as it wakes up.

Planting instructions
Plant in acidic soil with a pH between 4.5 and 5.5. Dig a hole twice as wide as the root ball and plant at the same depth as the container. Backfill with amended soil if needed, water thoroughly, and apply mulch such as pine bark or pine needles to maintain soil acidity and moisture. Continue regular watering during the first growing season to establish a strong root system.
Watering & sunlight
Water deeply once or twice per week during the first growing season to establish roots. After establishment, water regularly to keep soil evenly moist, especially during flowering and fruit development. Blueberries do not tolerate drought or soggy soil, so consistent moisture is key. Plant in full sun for the best fruit production and sweetest berries. Partial shade is tolerated, but yields may be reduced.
Care guide

PRUNING:
Prune in late winter while the plant is dormant. Remove dead, weak, or crossing branches and thin older canes to encourage new growth and maintain airflow. Light annual pruning supports better fruit size and production.

FERTILIZING:
Feed with an acid-loving fertilizer formulated for blueberries or azaleas in early spring. Avoid over-fertilizing, as blueberries are sensitive to excess nutrients. Avoid fertilizing for the first 2–3 months after delivery to allow the plant to adjust and establish.

WINTER PROTECTION:
Hardy in its growing zones. In colder regions, apply mulch around the base to protect shallow roots. Container-grown plants may benefit from additional insulation during extreme cold.
