Fill 2-gallon pots ¼ full with organic soil. Set one blueberry plant in the center of each pot. Backfill the soil and leave a 1-inch gap between the top of the soil line and the lip of the pot.
Water the blueberry plants immediately. Allow the water to flow through the layers of soil and out the holes in the bottoms of the pots. Keep the soil moist at all times. Deep waterings once a week should suffice.
Set the pots in an area that receives at least six to eight hours of full sun per day. Turn the pots every few days to ensure that the plants receive even amounts of light.
Feed the potted blueberry bushes an acid-based fertilizer. Apply the fertilizer to the soil around the blueberry bushes according to label directions. Most blueberries appreciate a dose of fertilizer once a month throughout the growing season.
Add a 2-inch layer of mulch on top of the soil in the blueberry pots. A layer of straw or bark chips improves water retention and keeps the roots of the blueberry plants warm in the winter.
Prune the blueberry bushes to encourage new growth and increase fruit production. Yearly removal of dead or damaged branches improves vigor. Prune the blueberry bushes back 1/3 of the way with a pair of pruning shears when they reach three years of age.
