Answer: It's difficult to grow blueberries in your region because they have a winter chilling requirement. For best results, choose a variety with a low chill requirement and amend the soil with lots of peat moss to lower the pH. They will grow and produce in partial-shade conditions as you've described. Here are a few varieties from which to choose:
Misty ? also known as Challenger, is a prolific bearer of good-sized berries that have terrific flavor. Nelson considers Misty to be the best all-around choice for San Diego area gardens.
Georgia Gem ? great flavor, very reliable under most climatic conditions; heavy production.
Blue Crisp ? a new introduction, good quality fruit, prolific producer.
Star ? very similar to Blue Crisp.
Cape Fear ? old-timer, quite popular and reliable, probably the most likely variety to be found at local nurseries.
Although these plants are self-fertile and they will produce fruit if planted alone, they will produce more fruit if two or more varieties are planted together so they can cross-pollinate.
In addition to the high quality of the fruit of southern high bush blueberries, the bushes, with their silver-green leaves and delicate white blossoms, are most attractive. The 4-foot-high plants can be planted as an attractive edible hedge.
Best wishes with your new blueberries!
