I forget when we bought our blueberry bushes, it must be at least eight years ago now. We planted them along the fence line that we then had in front of the garden to keep our Airedale girls away from the tomatoes (they picked their own) and the compost. The blueberries struggled in full sun for a few years and although we got the odd berry, I can't say they were a viable crop for us there. When we took the fence down, I put the blueberry bushes into pots to wait until the following spring when I intended to replant them in another spot. Well, those bushes started growing in the pots and looked very healthy so I decided to replace the soil, add compost and mulch and see how they did in the pots full time.
If grandchildren or birds discover the berries they'll be picked as soon as they change colour but leaving them on the vine for as long as possible will improve the sweetness and taste.
In that first year they gave us a couple of cups of blueberries, the following year there were more and this year the bushes are full of berries. They're in full sun most of the day and partial shade after about 3pm. I keep them fertilised with comfrey, a sprinkling of potash in spring and they're watered with rain water about three times a week. Good water is critical for blueberries. They thrive on rainwater and don't do so well on tap water containing minerals. They don't like any manures but they love acidic soil - so if you're growing camellias, you're in the right area for blueberries. I give them the cold leftovers and grounds of the coffee pot occasionally to boost the acidity in the pots a bit.
Keep the berries close together to aid in pollination. There are two blueberry seedlings on the side as well as one avocado I'm growing from seed. Propagation by cutting is quite easy and a good way to increase your stock of blueberries quickly.

As I was watering the garden yesterday morning, I noticed that two of the bushes are now as tall as me. They can be pruned which you would do after they finish fruiting. I prune ours like I prune my roses - vase shape, open in the middle, prune out any branches that cross over each other and any branches that touch. You can cut back any shoots that grow too tall. Once they get to the stage where you're pruning, they take off and grow into strong bushes.
Blueberries come in many different varieties and can be grown in cold and warm climates. We have Biloxi and Sunshine Blue. Of those two, here, Biloxi is the better. Both Biloxi and Sunshine Blue can set fruit without pollination from another plant but fruit is increased if you provide a means of cross pollination. Check varieties and pollination requirements here at Daley's site. It's easy to propagate blueberries. I took six inch cuttings at the end of winter and they started growing new leaves in spring. Doing this you can develop a nice stand of blueberries, just make sure you have the right varieties for your climate and types that pollinate each other. If you're growing them in the ground, they must have good drainage. They like to be wetter rather than drier, especially in summer, and here, watering three times a week with rainwater seems to keep them happy. Otherwise their a hardy plant, easy to grow, despite what you may have heard, and definitely worthwhile addition to the back garden.
