Bradford pear trees are ornamental , usually fruitless varieties of spring - flowering trees . They can grow to be 40 feet marvellous or more and make stately landscape painting specimens . However , they do n’t hold back much morphologic unity as they age , particularly in their massive limb . Their ( much modest ) root organization , though rife with lateral surface roots , is also problematic in older specimen .

History

These trees were once recommended in large surface area of the country for their beautiful spring blooming and quick , statuesque growth . This was in the main during the 1960s and ' 70s , concisely after the Sir Herbert Beerbohm Tree was introduced from China and then bred or grafted with American varieties of ornamental pear tree Sir Herbert Beerbohm Tree . The job that modern abode - owners often notice with the Sir Herbert Beerbohm Tree ( and specially the roots ) did n’t show up until the trees got much older . This is why Bradford pears are rarely recommended for long - term planting ( 25 years or more ) now .

Grafting and Suckers

Many origin advocate that Bradford pear be grafted onto the roots of another eccentric of cosmetic pear tree . These graftings would sometimes give way , take to upper parts of the tree dying off and falling while the roots of the other cosmetic tree started to sucker into foresightful , spindly forests . Non - engraft Bradford pears can still develop suckers if their surface root are damage , according to Clemson Cooperative Extension .

Surface Roots and Girdling

Bradford pear are prostrate to aerofoil ascendent and will grow properly back up through soil and sod thrown over them , harmonize to the University of Arizona Cooperative Extension . If the tree was grown in a container for too long , or if it was planted bare - ascendent in a small hole , the source may have girdle . This means that they grow in a circle , ineffectual to break through their confinement , and over the years the circular roots develop so fatheaded that they cut off the trunk . base like this should be loosened or , if necessary , removed before planting , harmonize to Bartlett Tree Research Laboratories .

Diseases

Most of the same root rot diseases that move pear can also damage a Bradford pear , include Texas root guff ( also bed as cotton wool source rot ) . These diseases pasture up when the roots sit in blotto ground for too long . Planting your Bradford pear in well - drained soil or on a slope will unremarkably be sufficient to keep these from being a problem . Texas root rot has no dependable remediation once it ’s established , say Arizona Extension Plant Pathology .

Top-Heavy

Bradford pears are tight - acquire trees with many leaden arm . The roots , by comparison , are smaller and not terribly strong . In area prone to storms , large mature trees have been known to blow over . If you have a mature tree diagram , reduce out some of the larger branches to reduce the free weight and provide less of a lead - trap canopy . Never top the tree ( thin the ends of all the branches or all of the top branches ) , since this will storm the tree to flush out with new , grave maturation at the top , say Purdue Plant and Pest Diagnostic Laboratory .
