20th Century (Nijisseiki) Asian Pear Tree for Sale
Find your perfect Asian pear tree near me at Nature Hills. The 20th Century Asian Pear, also known as Nijisseiki pear, delivers crisp, juicy fruit with exceptional sweetness. Available as bareroot Asian pear trees or container Asian pear trees for sale, this variety is one of the best Asian pears for home orchards.
Why Choose 20th Century Nijisseiki Asian Pear Tree
This Japanese heritage variety produces round, golden-yellow fruit with a crunchy apple-like texture. Nijisseiki Asian pear trees are vigorous growers reaching 15-20 feet tall and wide at maturity, making them excellent for backyard orchards and edible landscapes. The fragrant white spring blossoms attract pollinators while providing stunning ornamental value.
Key Features:
- Cold hardy Asian pear tree for zones 5-9
- Fire blight resistant Asian pear variety
- 300-400 chill hours required
- Self-fertile but produces better with a pollinator
- Harvest time: Late August to September
Asian Pear Tree Planting & Care Instructions
Plant your Asian pear tree in full sun (6+ hours daily) with well-draining soil. Space trees 12-15 feet apart for proper air circulation. Asian pear tree spacing can be closer (8-10 feet) for privacy screen or hedge applications.
Water deeply during establishment and fruit development. Apply balanced fertilizer in early spring. Mulch around the base to retain moisture and suppress weeds.
When to Prune Asian Pear Trees
Pruning Asian pear trees should occur in late winter while dormant. Remove crossing branches, water sprouts, and diseased wood. Thin fruit clusters to 4-6 inches apart for larger, higher-quality pears. Summer pruning controls vigor and improves light penetration.
Asian Pear Pollination Requirements
While 20th Century is partially self-fertile, planting an Asian pear companion tree significantly increases yields. Best pollinators include Shinseiki, Hosui, or Chojuro varieties. Cross-pollination with European pears is not effective.
Asian Pear Harvest Time & Storage
Pick Asian pears when they reach full size and color, typically late August through September depending on your climate. Unlike European pears, Asian pears ripen on the tree. Fruit should be firm with a slight give when gently pressed. Store harvested pears in the refrigerator for up to 3 months.
Disease Resistance & Common Problems
The Nijisseiki pear demonstrates good fire blight resistant characteristics compared to many Asian pear varieties. Monitor for typical fruit tree pests like codling moth and aphids. Proper spacing and pruning reduce disease pressure by improving airflow.
Compare Asian Pear Varieties for Backyard Orchards
20th Century offers exceptional cold hardiness and disease resistance, making it ideal for northern growers. For warmer zones, consider Shinseiki (zones 6-9) or the brown-skinned Hosui variety. All Asian pears share similar care requirements and landscape versatility.
Landscape Uses
Beyond fruit production, Asian pear trees serve multiple purposes: privacy screens, edible hedges, pollinator gardens, and food security landscapes. The uniform growth habit and attractive foliage create year-round interest.
