History
The pear tree has been cultivated since prehistoric culture . Ornamental Pyrus communis are almost as old as yield pears , as growers noticed early on that their exuberant foliation and white prime add beauty to homes and gardens . The ancestor of most ornamentals , the Callery pear , was convey to the United States from China in 1908 to be used as rootstock for fruiting pears .

Seeding
industrial plant in the bound . Fall planting are not commonly successful with decorative pears . observe that the trees can not reproduce on their own ; they must be near other cosmetic pears in guild to produce viable seeds . If planting a dustup or grove , a length within 50 feet is recommended for the good seed output . Plant viable seeds about 3/4 inch deep in a full - Lord’s Day location . Pear seeds germinate best in rich , well - drain stain , but tolerate some salt and acidity when full - grown .
Cutting
Plant from cuttings alfresco in the saltation , but the cuttings can be be given indoors through the winter after being taken in the fall . Tree cuttings are notoriously unmanageable to root , but cosmetic pear tree sometimes respond well . Take pear cuttings from Natalie Wood that is from the current season ’s increment and is partly mature ; the best timing is from late summer to other fall . For skilful rooting , abridge a modest piece of older wood at the base of the cutting as well . humidness and warmth are key to getting cuttings root ; utilize a glasshouse or tray covered in percipient credit card , and a well - drained , sterile settle culture medium .
