Bradford Pear

Pyrus calleryana 'Bradford'

tree

Bradford Pear is a fast-growing ornamental tree prized for its pyramidal shape, white spring flowers, and brilliant red fall foliage. It is a cultivar of Callery Pear, originally developed as a sterile, non-fruiting variety for urban landscaping. However, it has become invasive in many regions due to cross-pollination with other Callery pear varieties.

Growth Stages

Establishment (Year 1)

12 months

Young tree focuses on root development with minimal above-ground growth

Water deeply and regularly; stake if necessary; remove competing branches. Mulch 2-3 inches from trunk.

Rapid Growth (Years 2-5)

4 years

Tree grows quickly into characteristic pyramidal form; branches develop along central leader

Prune to maintain strong central leader; thin crowded branches; continue regular watering during drought

Flowering (Spring, typically March-April)

1-3 weeks

Abundant white flowers cover entire tree in early spring before leaf emergence

No action needed; minimal pollen allergen compared to some species. Enjoy display.

Summer Foliage (May-August)

4 months

Dense green glossy leaves; tree at full summer form with slight branching issues as tree ages

Monitor for pests and disease; prune dead or crossing branches; maintain watering during dry periods

Fall Color & Maturity (September-November)

2-3 months

Foliage turns brilliant red, orange, and purple; small inedible hard fruit may develop on female trees or near other Callery pears

Enjoy fall color display. Rake fallen leaves. Note: susceptibility to storm damage increases with age due to narrow crotch angles.

Companion Planting

Plan your garden →

Plant with:

Flowering dogwood Redbud Serviceberry Understory shade plants (hostas, ferns) Spring bulbs (daffodils, tulips)

Avoid planting near:

Other Callery pear varieties (cross-pollination concerns) Trees competing for space in small yards Areas where storm damage is problematic

Common Pests

Prune affected branches 12 inches below visible damage; sterilize tools; avoid high-nitrogen fertilizers that promote succulent growth
Strong water spray; insecticidal soap; encourage natural predators like ladybugs
Spray neem oil or insecticidal soap in spring; remove affected leaves
Dormant oil spray in winter; horticultural oil during growing season

Harvest Tips

Bradford Pears are ornamental trees; no harvest of fruit. Enjoy flowers in spring and foliage in fall. Prune selectively to maintain shape and remove crossing or weak branches to reduce storm damage risk.

Fun Facts

🌱 Bradford Pear was originally developed in the 1950s as a sterile, fruitless ornamental tree meant to avoid the messy, foul-smelling fruit of standard Callery pears. However, it was later discovered that Bradford pears could cross-pollinate with other Callery pear varieties, creating viable seeds and making the tree invasive in many regions.
🌱 The narrow branch crotch angles (acute angles between branches and trunk) that give Bradford Pear its attractive pyramidal shape are a significant weakness—branches frequently split and break under ice, snow, or wind loads, which is why many municipalities and arborists now recommend alternatives.
🌱 Bradford Pear flowers have a distinctive, somewhat unpleasant odor that some describe as fishy or spermatic, caused by volatile organic compounds. This smell attracts pollinating insects but can be noticeable to people nearby during peak bloom.
