Place your container you plan to use for your blueberry plant in a location that will receive full sun throughout the day.
Use potting soil formulated for azaleas, rhododendrons, or camellias to fill your container 1/3 to 1/2 full.
Spread the roots of your dwarf blueberry plant and place the root ball on the soil in the center of your container. Then, cover the roots and continue to fill your container with the acidic formulated potting soil. Stop when you get to about 4 inches from the top of your container.
Water your blueberry plant thoroughly after planting. Blueberry plants thrive when you grow them in consistently moist soil. It is important to keep the soil moist throughout the growing season, but do not allow your blueberry plant to stand in water.
Add 3 to 4 inches of mulch to your container, around your blueberry plant. Leave an inch or two open, with no mulch, around the base of your blueberry plant trunk. By not putting mulch up against the trunk, you eliminate many potential problems with disease and insects. The mulch will, however, help keep the soil evenly and consistently moist.
Fertilize your established blueberry plant with a fertilizer formulated for acid loving plants, such as azaleas, rhododendrons, or camellias. Fertilize once a month, starting in the spring through August, then discontinue until the following spring. For newly planted blueberry plants, wait 4 to 6 weeks after planting before you fertilize your plant.
