Southland Blueberry

Vaccinium corymbosum 'Southland'

shrub

Southland is a high-bush blueberry variety bred for warm climates, particularly suited to the southeastern United States. It produces medium to large berries with excellent flavor and requires relatively low chill hours compared to traditional northern blueberry varieties. The plant is a vigorous, deciduous to semi-evergreen shrub that reaches 4-6 feet tall.

Growing Conditions

☀️

Sun: Full sun, 6-8 hours daily for best fruit production

💧

Water: Consistent moisture; water deeply 1-2 inches per week. Blueberries need regular watering, especially during fruit development. Mulch heavily to retain moisture and maintain soil acidity.

📏

Spacing: 48 inches

📅

Days to maturity: 2-3 years before significant fruit production; full production by year 4-5

🌱

Planting depth: Plant with top of root ball at or slightly above soil level; Southland prefers slightly higher planting than northern varieties

Soil

Type: Well-draining sandy loam or acidic loam soil

pH: 4.5-5.5

Amendments:

Peat moss or composted pine bark (30-50% of planting mix) Sulfur to lower pH if needed Aged compost Pine needles as mulch

Growth Stages

Establishment

1 year

First year after planting; plant develops root system with modest leaf growth

Remove flower buds the first year to encourage root establishment. Water consistently 2-3 times weekly. Apply 3-4 inches of acidic mulch (pine bark, pine needles). Avoid fertilizer until second year.

Vegetative Growth

2 years

Years 2-3; plant branches develop and canopy fills in; some flowering begins

Allow limited flowering in year 2. Feed with acid-forming fertilizer (ammonium sulfate or specialty blueberry formula) in early spring. Prune to remove crossing canes and shape plant. Continue consistent watering.

Flowering

2-3 weeks

Delicate pink or white bell-shaped flowers appear in clusters (corymbs) in spring (March-April in southern regions)

Protect flowers from late frost if temperatures drop below 32°F. Do not fertilize during flowering. Ensure pollinator access; bees are essential. Maintain steady moisture levels.

Fruiting

8-12 weeks

Flowers develop into small green berries that gradually enlarge and change color from green to red to deep blue (May-July depending on zone)

Continue watering deeply; berries need consistent moisture for optimal size and flavor. Apply balanced fertilizer after flowering. Thin fruit if overcrowded for larger berries. Watch for pest damage.

Harvest & Dormancy

4-6 weeks harvest; 4-5 months dormancy

Mature blue berries are ready to pick; foliage may remain semi-evergreen in warmer zones but typically enters dormancy in late fall

Harvest ripe berries (they should fall easily into your hand). Prune out dead or crossing wood in late winter. Reduce watering in dormancy but don't let soil dry completely. Apply dormant oil spray if pest issues occurred.

Companion Planting

Plan your garden →

Plant with:

Another blueberry variety (cross-pollination improves fruit set) Azaleas Rhododendrons Camellias Heathers Huckleberries

Avoid planting near:

Limestone or alkaline soil regions (blueberries need acid soil) Black walnut (allelopathic effect) Areas with poor drainage or clay soil Fruit trees requiring different pH

Common Pests

Yellow sticky traps, insect netting over fruit, spinosad sprays in mid-June through July, sanitation of dropped fruit
Prune out infested canes, maintain plant vigor with proper watering and fertilization, avoid plant stress
Dormant oil sprays in winter, insecticidal soap in growing season, pruning of heavily infested branches
Hand-pick in early morning, neem oil spray, encourage native predators, avoid traps near plants
Ensure good air circulation through pruning, sulfur sprays, avoid overhead watering, fungicides if severe
Remove mummified berries and leaf litter, fungicide sprays at bud break and flowering, promote air circulation

Uses

🍳

Fresh eating and baking

Culinary

Southland blueberries have excellent flavor suitable for fresh consumption, pies, muffins, jams, and smoothies. The berries are medium to large and sweet with minimal tartness. [source]

💊

Antioxidant health benefits

Medicinal

Blueberries are rich in anthocyanins and other polyphenol antioxidants that support cardiovascular health, cognitive function, and inflammatory response. Southland berries provide the same nutritional benefits as other high-bush varieties. [source]

🦋

Wildlife food source

Wildlife

Blueberry bushes provide food for songbirds, deer, and other wildlife. The flowers attract pollinators, and berries are eagerly consumed by birds if not harvested first. [source]

🏠

Natural dye source

Household

Blueberry juice can be used as a natural dye for textiles and artistic projects, producing blue to purple hues. The dye is semi-permanent and environmentally friendly. [source]

🍳

Preserving and value-added products

Culinary

Abundant harvests can be frozen, canned into jams, or made into syrups and cordials. Southland's heavy production makes it excellent for preservation. [source]

Harvest Tips

Berries are ready when uniformly deep blue and fall easily into your hand (typically June-July in zone 8-9). Harvest every 3-4 days at peak ripeness. Southland produces heavy crops; expect 8-12 pounds per mature plant. Berries do not continue to ripen after picking, so wait until fully blue. Store in refrigerator up to 3 weeks or freeze for longer storage.

Fun Facts

🌱 Southland blueberry was specifically bred at the University of Florida to require only 200-400 chill hours (compared to 800-1000 for northern varieties), making it one of the lowest-chill blueberry varieties available for warm climates.
🌱 Blueberry bushes can live 40-60 years or longer, and a mature Southland plant may produce fruit continuously for decades with proper care, making it an excellent long-term landscape investment.
🌱 Blueberries require cross-pollination with a different blueberry variety to achieve the best fruit set and largest berries; planting at least two compatible varieties dramatically increases yield.
