Growth Stages

1

Establishment (Year 1)

Year 1

Young plant focuses on root development and establishing structure; limited flowering and fruiting expected.

Remove flower buds first year to encourage root establishment. Water consistently. Apply 3-4 inches of mulch around base, keeping it 4-6 inches away from stem.

2

Vegetative Growth (Years 2-3)

Years 2-3

Plant develops robust upright framework with dense foliage; begins producing flowers and small fruit crops.

Prune lightly to shape plant and remove crossing branches. Allow some flowering and fruiting while prioritizing growth. Maintain consistent watering and mulch.

3

Flowering (Spring)

3-4 weeks

Delicate white or pale pink bell-shaped flower clusters (racemes) appear in spring before or as leaves emerge.

Do not fertilize heavily during flowering (can reduce fruit set). Monitor for spring frost damage to flowers. Flowers are self-fertile but cross-pollination with other blueberry varieties improves yield.

4

Fruiting (Summer-Fall)

8-12 weeks

Small green berries develop from flowers, gradually enlarging and turning blue (mid-July through September for 'Legacy'). Berries are large, firm, and light blue when ripe.

'Legacy' is a late-season variety; berries ripen primarily in August-September. Provide consistent water during fruit development. Protect from birds with netting if desired.

5

Dormancy (Winter)

3-4 months

Plant drops leaves and enters cold dormancy; buds harden for winter survival.

No pruning during dormancy. 'Legacy' is very winter hardy (survives -20°F or colder). Maintain mulch layer for insulation.

Common Pests

  • Use yellow sticky traps; apply spinosad or approved organic insecticides in mid-summer; remove and destroy infested berries

  • Prune to improve air circulation; apply spinosad at bloom time; hand-pick damaged fruit

  • Increase humidity with regular watering; spray with water or neem oil; maintain plant vigor

  • Remove affected leaves; apply neem oil or spinosad; encourage natural predators

  • Install bird netting over plants during fruit ripening; use scare tactics; plant extra berries to share

  • Remove mummified berries from plant and ground; improve air circulation through pruning; apply sulfur fungicide at petal fall stage

Harvest Tips

'Legacy' is a late-season blueberry, producing ripe berries from late July through September (peak August-September). Pick berries when they are fully blue and slightly soft to the touch; they should come off easily with a gentle tug. Berries do not ripen further after picking. Harvest every 2-3 days during peak season. A mature plant can yield 10-15 pounds of fruit per year.

Fun Facts

  • 🌱 'Legacy' was developed at the University of Florida and is particularly prized for extending the blueberry harvest season into fall, allowing fresh blueberries to be picked in late September and early October in many regions.
  • 🌱 Blueberries are one of the few foods naturally blue in color; their deep blue hue comes from anthocyanin pigments that can turn red or purple in acidic conditions and blue in neutral to slightly acidic soil.
  • 🌱 A single mature highbush blueberry plant can live and produce fruit for 40-50+ years with proper care, making it a long-term investment in a perennial garden.
