The dwarf Bushel and Berry collection of blueberry vegetation are also bred to be modest and do perfectly in containers. You should maintain in mind that blueberry generate will be ideal if you have at the very least two distinctive types escalating in the vicinity of just about every other. Even if the plant label states self-fertile. The common, northern higher bush blueberries will do perfectly if planted in a large container.

Consider the container: Dwarf blueberries should be planted in a container at minimum 18 inches wide and about as deep. Northern substantial bush blueberries will need a container at minimum 24 inches deep and about 18 inches deep or so. This usually means a 15-to-20-gallon nursery container. If your soil is not suited for blueberry society, you can sink these substantial containers into the soil, leaving the top of the container about 4 to 6 inches over the soil line.

Total sunshine: Blueberries have to have at least six hours of sunlight a day. On the foggy coast, even extra. Properly-tended bushes will always search great with fewer sunshine, but fruit yield will be lower and flavor good quality moderate.
