Hi CP
I have a collection of 3 different types of blueberry. I “compromised” by creating a small raised bed for them, which I filled with ericaceous compost. In the winter, I mulch with pine needles.
I understand that blueberries are moisture loving plants, so watering seems to be inevitable; I give mine priority for watering and endeavour to keep the soil moist.
Useful information can be found at:

Keep them covered as the birds love the berries and they will disappear in the twinkling of an eye!
Best wishes
Beverley
