Growing your own fresh blueberries doesn't have to mean you need a lot of ground or garden space available at your home. With the right dwarf variety you can grow a blueberry bush in containers and have as many plants as you would like no matter how much space you have available. You will, however, need to make sure you set your blueberries in a full-sun area and be certain to water your blueberries frequently.
Select a large pot at least 2 feet across and about 20 inches deep. Drill three or four small ¼-inch drainage holes, if needed, into the bottom of the pot.
Fill the bottom inch with gravel followed by a ½-inch deep layer of pea gravel. Mix together equal parts acidic potting soil, peat moss and compost, and fill the container half of the way full with the mix.
Set your blueberry bush into the new container and center it. Hold the blueberry bush in place as you fill the remainder of the pot with more potting soil mix. Adjust the plant as needed to be sitting in the soil at the same level it was before.
Set your container in an area where your blueberry plant will receive at least five to six hours of direct sunlight each day. Water the soil to moisten it thoroughly and water it consistently any time the soil is dry to the touch an inch below the surface. Over the summer months this may mean adding water almost daily. Spreading a 1-inch layer of pine needles can help hold water in the soil.
Use a water-soluble acidic fertilizer on your blueberry bush as often as suggested according to the manufacturer's instructions. Don't over-fertilize, however, or you may see many leaves and not very many berries. You should be able to harvest blueberries after the first year.
