Growth Stages

1

Dormant/Establishment (Year 1)

First 12 months

Newly planted bare-root or balled-and-burlapped tree focuses on root development. Limited above-ground growth; tree may leaf out but produces no fruit.

Water regularly to establish roots. Support with stake if needed. Prune to open central leader form. Remove any flowers that appear to direct energy to root development.

2

Vegetative Growth (Years 1-2)

First 2 years

Tree develops scaffold branches and overall structure. Foliage is healthy and vigorous; no significant fruiting occurs.

Prune to establish strong framework with 3-4 main scaffold branches at wide angles. Thin competing branches. Apply balanced fertilizer in spring. Monitor for pests and diseases.

3

Flowering (Early Spring, Year 2-3+)

2-3 weeks

White, fragrant flowers bloom in clusters before leaves fully emerge, typically appearing 1-2 weeks before many other pear varieties.

Thin flower clusters to improve fruit size and reduce overcrowding. Ensure compatible pollinator variety nearby (Bartlett, Bosc, or Kieffer are good pollinators). Protect from late frosts with frost cloth if needed. Avoid pruning during flowering.

4

Fruit Development and Growth (Late Spring-Summer)

8-12 weeks

After pollination, small fruits begin enlarging rapidly. Fruit is green initially, then develops the characteristic golden-yellow color with red blush.

Thin fruit to 1 pear every 6 inches of branch for optimal size and quality. Water deeply and consistently. Provide supplemental calcium (lime) to prevent disorders. Support heavy branches with props or ties.

5

Harvest (Late August-Early September)

2-4 weeks peak harvest period

Fruits reach full size and develop rich flavor. Skin is golden-yellow with warm blush; fruit will yield slightly to gentle pressure at the neck.

Harvest slightly before fully ripe for best storage. Pears should be mature but firm; they ripen off the tree at room temperature. Use a gentle twist-and-lift motion. Lay fruit in cool storage or ripen indoors.

Common Pests

  • Spray with neem oil or insecticidal soap when slugs appear (typically early summer). Prune and remove affected foliage. Encourage natural predators.

  • Use pheromone traps to monitor. Apply Bt (Bacillus thuringiensis) or kaolin clay spray in early spring and repeat every 2-3 weeks. Remove dropped fruit promptly.

  • Spray dormant oil in late winter. Use insecticidal soap during growing season. Monitor with sticky traps. Apply neem oil as needed.

  • Prune infected branches 12 inches below damage; sterilize pruners between cuts. Remove blighted branch tips immediately during season. Apply copper or antibiotic sprays (streptomycin) in spring during bloom. Plant resistant varieties nearby.

  • Apply lime-sulfur or fungicidal sprays starting at tight cluster stage and repeat every 7-10 days through early summer. Remove infected fruit promptly. Improve air circulation through pruning.

Harvest Tips

Clapp's Favorite ripens in late August to early September, 1-2 weeks before Bartlett. Harvest when fruit reaches full size and color but is still firm (slightly immature). Pears ripen better off the tree—place in cool storage at 65-70°F for 3-5 days, then move to room temperature to finish ripening. Handle gently to avoid bruising. Store ripe fruit in refrigerator for 1-2 weeks.
