The Bradford pear tree (Pyrus calleryana; also known as Callery pear) is grown in USDA hardiness zones 6-8. The trees' neat form, thick foliage and beautiful white blooms in the spring make them popular on streetsides, in parks and as accent trees. According to the University of Georgia School of Forest Resources, the Callery pear is named after a French missionary to China in the mid-1800s, and the tree is native to China, Vietnam, Japan, and Korea. Bradford pears are short-lived (15 to 25 years) and tolerant of pollution.
Plant your Bradford pear in well-drained, but moist, site that receives full sun. Micro-sites that concentrate cold air and have fogs, mists or extended periods of high relative humidity should be avoided, according to the School of Forest Resources. You can plant your tree in heavy clay, as long as it has good drainage, but avoid sites with very alkaline soil.
Water your tree weekly for the first year. After that, water only during a serious drought; the Bradford pear is drought-tolerant.
Fertilize lightly. Excessive nitrogen can make the tree susceptible to aphids, scale insects, fire blight and other bacteria diseases. Prune during the late fall or winter to avoid pest problems. When pruning, sanitize your tools with a bleach solution.
