We had blueberry bushes at home that had never supplied but a few berries for the squirrels and birds. They were in too much shade to thrive. So I transplanted them to the farm. I began with commercial compost in each mound along with a bit of complete organic fertilizer. While I was at it I bought four more bare root plants to increase production.
I discouraged fruiting of these for their first season, saving their efforts until they had more opportunity to develop good root systems. So we wait until the next season.
