Blueberries are ideally suited for growing in containers because they have a shallow root system that easily adapts to the tight confines of a container. Another reason to grow them this way is that blueberries require specialized soil with a low, acid pH (ideal range: 4.5 to 4.8).
With in-ground plantings, maintaining this low pH may require a concerted, ongoing effort. In a container or raised bed, you can create the ideal soil pH at planting time and have it last for 6-10 years before you have to tackle major soil amending. (At that point, bushes also benefit from root pruning, so it’s a win-win situation.)
