Transplanting blueberries

Question

Can I safely transplant my blueberry bush to a larger container while it’s flowering?

Answer 1

The best time to move the plant to a larger pot is early spring before the new growth begins.
I would wait until the bush is done producing fruit to ensure the plants health.
