How to Grow Huge Blueberries

Clear a bright, sunny location to plant your blueberry plants. Blueberry plants should get full sunlight for at least eight hours every day with little to no shade.

Test the soil pH using a soil test kit. According to Oregon State University, blueberries require a soil pH of 4.5 to 5.5. If your soil's pH is too high, add 1/10 lb. of sulfur for every square feet of soil to lower the pH by .5. If your soil's pH is too low, add 3 lbs. of limestone for every 100 square feet of sandy soil to raise the pH .5. Add 4 lbs. for loamy soils.

Choose at least two cultivars of blueberry bushes to plant -- including those bred to produce larger than standard berries. Michigan State University Extension advises that cross-pollination between two different types of blueberries leads to larger berries.

Dig a hole 1 inch deeper than the nursery pot that your blueberries came in and approximately 8 inches wide. Plant the blueberry bushes 5 feet apart with rows at least 10 feet apart.

Place the blueberry bush into the hole and cover with native soil. Pack the soil loosely around the base of the plants.

Water the bushes with 1 to 2 inches of water immediately after planting. Water with 1 to 2 inches of water every week to ensure the largest blueberries. Blueberry plants require a lot of water to produce fruit.

Pinch off all the flowers that develop in the first season. This allows the plant to devote its energy to becoming established in the garden, so it can support a strong crop of berries the next year.

Prune blueberries in the winter by removing all dead and diseased stems. Do not remove new growth until after the plant is 8 years old.

Apply one to one and a half pounds of 10-10-10 fertilizer for every 100 square feet of soil. Apply a half a pound when the plant begins to bloom and the remained of the fertilizer four to six weeks later.

Cover the base of the plants with 4 inches of wood chips or mulch after planting. This will help hold in moisture and keep the weeds out.
