Blueberry cultivation methods and techniques.

First, seedling selection.

When planting blueberry trees, it is necessary to choose varieties with high yield, less pests and diseases, and large fruits, and the age of the trees is best more than two or three years, so as to ensure that the root system is strong and grows vigorously, so that the blueberry seedlings can resume growth faster after planting.
