Not only do blueberry bushes produce baskets full of tasty, colourful berries, but they also make attractive, eye-catching plants. The shiny, deep green foliage adds visual interest to any setting, and the compact growth habit is suited to life in containers. Though the bushes are traditionally placed outdoors, if you set blueberry plants in a sunny spot and give proper care and attention, they will adapt to life indoors.
Buy blueberry plants. For indoor growing, stick with dwarf-type bushes as they tend to be more compact. For optimum berry production, choose several varieties to have an adequate amount of genetic material available for successful cross-pollination.
Buy one 5- to 10-gallon planter, pot or barrel for each blueberry bush. Choose containers that have holes in the bottom for adequate drainage.
Place each container on a plastic tray to shield the floors from moisture damage.
Fill one-third of each planter with equal amounts of commercial potting soil and shredded peat moss.
Add 2 tbsp granular sulphur to each planter, then toss the soil gently with your hands, thoroughly incorporating the compound into the potting mixture.
Place the root ball of the blueberry bush into the planter and gently push the soil around the roots, pressing firmly with your fingers to hold the plant in place. Add more potting soil and peat moss, filling the container to within 3 inches of the rim. Sprinkle a 1-inch layer of shredded bark mulch over the soil but away from the trunk of the shrub.
Water the blueberry bush thoroughly, slowly pouring water around the base of the plant. Add water until fluid begins to seep from the bottom of the planter. Water the plant twice a week during the spring and summer, once a week during autumn and once a month during the winter as this coincides with the natural dormancy phase.
Place the blueberries in a sunny location that provides at least six hours of sunlight each morning then shade later in the day.
Fertilise the blueberry bushes with an all-purpose water-soluble plant food once a month. Sprinkle 1 tbsp granules around the base of the plant, then add water to activate the chemical compounds in the fertiliser.
