This period of blueberry seedlings is easy to transport, easy to manage and colonize. After planting in autumn, a small amount of flowering and fruiting can be achieved in the second year, and normal flowering and fruiting can be achieved in the third year. The full fruiting period is five years later. Family potted blueberries are properly managed and the fruiting period can be maintained for 35 years.

2. Seedling selection of potted blueberries:
