How to Grow Jubilee Orange

Jubilee Orange

Citrus × sinensis 'Jubilee'

tree

Jubilee Orange is a compact, cold-hardy citrus tree producing sweet, seedless or near-seedless oranges with excellent flavor. It was developed in Florida to withstand cooler temperatures than most citrus varieties, making it suitable for regions that would otherwise be too cold for orange cultivation. The tree is highly ornamental with fragrant white flowers and dense foliage.

Growing Conditions

☀️
Sun: Full sun, 8+ hours daily for optimal fruiting and flavor development
💧
Water: Regular watering during establishment and growing season; keep soil consistently moist but not waterlogged. Reduce watering in winter. Mature trees are moderately drought-tolerant once established but produce better fruit with consistent moisture.
📏
Spacing: 120-180 (10-15 feet apart, depending on rootstock and desired canopy size) inches
📅
Days to maturity: 3-4 years to first significant fruit production; mature production by 5-7 years
🌱
Planting depth: Plant at same depth as root ball; graft union should be 2-3 inches above soil line

Soil

Type: Well-draining sandy loam or loamy soil
pH: 5.5-7.0
Amendments:
Compost Citrus fertilizer (balanced or slightly nitrogen-rich) Mulch (2-3 inches) Sulfur if pH is too high

Growth Stages

1

Establishment

1-2 years

Young tree developing root system and trunk structure; minimal fruiting.

Water deeply and frequently; stake for support in windy areas; do not allow heavy fruit production; maintain regular pruning for shape.

2

Vegetative Growth

Year 2-3

Rapid growth of branches and foliage; tree building framework; light flowering begins.

Apply balanced citrus fertilizer 3-4 times per year; prune to develop strong scaffold branches; thin excessive growth.

3

Flowering & Pollination

4-6 weeks in spring

White, fragrant flowers appear; typically in spring (March-April in northern regions); flowers are self-fertile.

Maintain consistent watering; avoid heavy nitrogen to prevent excessive vegetative growth; allow bees and other pollinators access.

4

Fruit Development & Maturation

6-8 months (June/July through November/December)

Small fruit sets and enlarges; color changes from green to orange (typically October-December); high sugar content develops.

Reduce nitrogen, increase potassium and phosphorus; maintain steady watering to prevent fruit cracking; thin fruit if overcrowded (1 fruit every 6 inches of branch).

5

Harvest & Winter Rest

December-February

Fruit fully mature and sweetest; leaves may show winter color; minimal growth activity.

Harvest as needed; reduce watering in winter; minimize pruning; protect tree during hard freezes; resume feeding in late winter/early spring.

Common Pests

  • Monitor for mottled foliage; spray neem oil or horticultural oil; maintain tree vigor; consult local agricultural extension on chemical controls and quarantine requirements.

  • Prune out heavily infested branches; spray dormant oil in winter; use horticultural oil during growing season; encourage natural predators.

  • Spray with water to dislodge; apply sulfur dust or neem oil; maintain humidity; avoid over-fertilizing with nitrogen.

  • Remove heavily damaged leaves; apply neem oil to new growth; avoid nitrogen-heavy fertilizing; rarely causes significant crop loss.

  • Spray insecticidal soap or neem oil; use yellow sticky traps; encourage beneficial insects.

Uses

🍳

Fresh consumption and juice

Culinary

Jubilee Oranges are excellent fresh-eating citrus with sweet flavor and low acidity. They are also suitable for fresh-squeezed juice, though some seeds may be present in some trees. [source]

🍳

Zest and marmalade

Culinary

The fragrant peel can be zested for baking, cooking, and tea. The rind is excellent for homemade marmalade and candied peel due to balanced sweetness and acidity. [source]

💊

Vitamin C supplementation

Medicinal

Oranges are rich in vitamin C, supporting immune function and antioxidant protection. Fresh orange juice or eating the fruit whole provides bioavailable citrus nutrients. [source]

🏠

Ornamental and fragrance

Household

The tree's dense, attractive foliage and abundant fragrant white flowers make it a beautiful landscape specimen. Flowers provide delicate orange blossom fragrance in spring. [source]

🦋

Pollinator support

Wildlife

Spring flowers attract bees, butterflies, and other pollinating insects. Mature fruit also provides food and shelter for birds and beneficial insects. [source]

Harvest Tips

Fruit matures and develops full sweetness from November through January in most regions. Harvest when fully orange in color; use hand-picking or small pruning shears to avoid damaging branches. Fruit can remain on tree 4-6 weeks after full ripeness without significant quality loss. For best flavor, allow fruit to mature fully on the tree rather than harvesting early. A mature Jubilee Orange tree produces 50-200 pounds of fruit annually, depending on age, growing conditions, and freeze damage.

Fun Facts

  • 🌱 Jubilee Orange was developed at the University of Florida specifically to extend citrus cultivation into zones normally too cold for oranges, surviving temperatures down to 5-10°F with minimal damage.
  • 🌱 The variety is largely seedless or contains very few seeds, a trait inherited from mandarin genetics, making it more convenient for fresh eating and juice production.
  • 🌱 Jubilee Orange trees can live 50-100+ years with proper care, becoming increasingly productive and ornamental with age, making them a long-term landscape investment.
