Growth Stages

1

Dormancy & Planting

Late winter to early spring

Bare-root or container trees in late winter to early spring; buds begin swelling

Plant in early spring while dormant; ensure graft union is above ground; stake young trees for support; apply dormant oil spray if needed for pest prevention

2

Leafing & Early Growth

Spring (4-6 weeks)

Leaves emerge, tree establishes root system, new shoots appear

Water consistently during dry spells; remove competing vegetation; apply balanced fertilizer in spring; remove any flower buds first year to encourage establishment

3

Flowering

Mid-spring (2-3 weeks)

Abundant white-pink flowers appear in clusters; attracted by bees and other pollinators

Requires cross-pollination; plant compatible pear variety nearby (Bartlett, Anjou, Seckel); thin excessive flowers if desired; protect from late frosts

4

Fruit Development & Maturation

Late spring through late summer (12-14 weeks)

Small fruit forms, grows to medium size (4-5 oz), develops golden-yellow color

Thin fruit to one per cluster to encourage larger, quality fruit; water during drought; fertilize with potassium-rich fertilizer mid-summer; monitor for pest and disease

5

Harvest & Dormancy

Late summer through winter

Fruit reaches mature size and color; ripens off tree; leaves turn yellow in fall and drop

Pick fruit when firm and mature (late August-September); ripen at room temperature 2-4 days; prune in winter dormancy; apply mulch for winter protection

Harvest Tips

Harvest fruit in late August to early September when firm and showing golden color. Pears ripen off the tree—pick slightly early and store at room temperature (65-70°F) for 2-4 days until slightly soft. Check daily for ripeness by gentle pressure near the stem. Do not allow to ripen fully on tree or flesh becomes grainy.

Fun Facts

  • 🌱 Moonglow was developed by the USDA in the 1950s specifically for cold-hardiness and fire blight resistance, making it one of the most disease-resistant pear varieties available.
  • 🌱 Pears are one of the few fruits that ripen better off the tree than on it—harvesting at firm stage and allowing indoor ripening creates superior texture and flavor.
  • 🌱 Moonglow requires cross-pollination with another pear variety to produce fruit; a single tree will not bear fruit without a compatible pollinator nearby.
