Growth Stages

1

Establishment

1-2 years

Young tree develops root system and framework; minimal fruiting. Tree is 3-6 feet tall with 3-5 main scaffold branches forming.

Stake for wind protection. Remove early flower buds to direct energy to growth. Water regularly. Prune to open center form.

2

Young Fruiting

1-2 years

Tree begins setting fruit clusters; 6-12 feet tall with established branching. Fruit appears at 3-4 years of age.

Thin fruit to 1 per cluster (8-10 inches apart) when walnut-sized for larger fruit. Thin aggressively in first years. Apply boron foliar spray if deficiency suspected.

3

Flowering

2-3 weeks in spring

White or pale pink blossoms appear in early spring before full leaf emergence. Flowers are self-fertile but benefit from cross-pollination.

Protect flowers from late frosts. Thin flower buds if excessive (1 flower per spur). Ensure adequate boron for fruit set. Monitor for pear psylla.

4

Fruit Development

12-16 weeks

Fruit enlarges rapidly after petal fall, reaching 1-2 pounds. Skin transitions from green to golden-brown. Tree is heavily laden with developing fruit.

Maintain consistent water supply. Thin fruit to largest specimens if needed. Apply calcium spray to prevent disorders. Support heavy branches with props.

5

Harvest Maturity

2-4 weeks

Fruit reaches full size and golden-brown color; begins to soften slightly. Mature fruit is 4-5 inches in diameter and weighs 14-28 ounces.

Harvest when fruit easily detaches from branch. Handle carefully to avoid bruising. Fruit may be picked slightly early and ripened off-tree. Store at 32-40°F.

Companion Planting

Common Pests

  • Monitor for honeydew and sooty mold; spray dormant oil in early spring; use horticultural oils or insecticidal soaps; promote natural predators

  • Use pheromone traps; remove infested fruit; apply spinosad or kaolin spray; thin fruit for better monitoring

  • Spray with spinosad or insecticidal soap when larval damage appears; water-spray affected leaves

  • Prune out infected branches 12 inches below damage in dry weather; sterilize tools; avoid excess nitrogen fertilizer; select resistant rootstocks

  • Remove infected leaves and fruit; apply sulfur or copper fungicide; ensure good air circulation; avoid overhead watering

Harvest Tips

Atago pears mature in late August to September depending on location. Harvest when fruit detaches easily with a gentle twist but while still firm (for better handling and storage). Pick slightly immature fruit to ripen off-tree at room temperature for 3-7 days to achieve optimal flavor and texture. Do not wait for fruit to drop. Store mature fruit at 32-40°F for 2-3 months. Handle gently to avoid bruising.

Fun Facts

  • 🌱 Atago pears are among the largest pear cultivars, often weighing as much as a grapefruit, and individual fruits can reach 2 pounds or more under good growing conditions.
  • 🌱 The cultivar originated in Japan and remains a premium fruit there; the name 'Atago' refers to a temple on Mount Atago near Kyoto, Japan.
