How to Grow Blueberries in the South: Varieties, Soil, and Care

Blueberries in the South: A Long-Term Investment That Pays Off

Blueberries are one of the best fruit investments a southern gardener can make. They live for decades, produce more fruit with each passing year, and the fruit is worth a premium at any grocery store. Once you have a mature blueberry patch, you will wonder why you ever bought blueberries at the store. The key is choosing the right varieties and getting the soil right from the start.

Which Blueberry Variety Is Right for Your Zone?

Variety selection is the most important decision in blueberry growing. Choose the wrong type and your plants will survive but never thrive. In the South, three main types perform well depending on your location.

Rabbiteye blueberries are native to the Southeast and are the most widely adapted for zones 7 through 9. They are heat-tolerant, drought-resistant once established, and produce large crops of excellent fruit. They need very few chill hours, which makes them reliable across most of the Deep South. Popular rabbiteye varieties include Tifblue, Brightwell, and Powderblue. Plant at least two different varieties for cross-pollination.

Southern highbush blueberries are a better fit for zones 8 through 10 where winters are mild. They ripen earlier than rabbiteye varieties and include popular options like Sunshine Blue, Emerald, and Star. Sunshine Blue is particularly compact and works well in containers or smaller garden spaces.

Northern highbush varieties are generally not recommended for the Deep South but can work in the upper zones of North Florida and the Carolinas where chill hours are higher.

Getting the Soil Right for Southern Blueberries

Blueberries require acidic soil with a pH between 4.5 and 5.5. If your soil pH is too high, the plants will look sickly and yellow regardless of how much you fertilize them. Test your soil before planting. Sandy southern soils often have a naturally low pH and can be ideal with some organic matter added. Clay soils in the Piedmont and upland South need more work to get right.

To lower soil pH, incorporate elemental sulfur several months before planting. Adding peat moss or pine bark compost to the planting hole helps create the right acidity and drainage. Mulch heavily with pine straw after planting to maintain acidity as the straw breaks down.

Planting and Establishing Blueberries

Plant blueberries in full sun with at least 6 hours of direct sunlight daily. Dig a hole twice as wide as the root ball and slightly shallower than its depth. Mix the native soil with peat moss or pine bark and backfill. Water deeply after planting and keep consistently moist during the first growing season. Do not let newly planted bushes produce fruit in the first year. Pinch off any flowers so the plant directs all energy into root establishment.

Fertilizing and Ongoing Care

Fertilize blueberries with an acid-forming fertilizer formulated for azaleas and blueberries. Apply in early spring as new growth begins and again in early summer. Avoid over-fertilizing with nitrogen, which promotes excessive leaf growth at the expense of fruit. Water consistently during fruit development in spring and early summer. Prune lightly in late winter, removing dead, damaged, or crossing branches.

What to Expect from Mature Blueberry Plants

Blueberries produce modestly in years two and three while they establish. By years four and five, a healthy rabbiteye plant can produce several gallons of fruit per season. By years eight to ten, a mature plant can yield 10 to 20 pounds of berries annually. Bird netting is almost essential at harvest time since birds will compete for every berry. Install netting before fruit begins to color.
