Do blueberry plants require cross-pollination to flower and produce fruit?

Blueberry plants do not strictly require cross-pollination to flower and produce fruit, as many varieties are self-pollinating. However, cross-pollination can significantly enhance fruit set, size, and overall yield. Planting multiple varieties nearby can improve pollination efficiency and lead to better quality fruit. Therefore, while not essential, cross-pollination is beneficial for optimal blueberry production.
