Second in popularity for growing in the home garden behind apple trees, pear trees (Pyrus communis) are reliably hardy in USDA Hardiness Zones 4 through 8, and therefore can be grown anywhere in Rhode Island. Although many varieties are advertised as self-fertile and need no other pear tree nearby to produce a crop, all varieties of pears will bear a larger crop if planted near a pollinator. Many varieties of pears are available in dwarf form that grow only about 10 to 15 feet high. These smaller trees are ideal for planting in small urban or suburban yards. They take up less space and are easier to prune, spray and harvest.
This variety withstands unfavorable conditions well with good disease resistance. Conference blooms in mid-spring and ripens in mid- to late-September. Partially self-fertile, a Conference pear tree doesn't need a pollinator, but it will produce a larger crop if another pear variety is planted nearby.
A self-fertile variety, this pear tree will produce a crop even if no other pears are growing in the vicinity. Improved fertility grows well and produces a heavy crop even in cool weather. Fruit ripens in mid-September and the tree displays a red leaf color in fall.
Bartlett pears are one of the most popular pears in cultivation. They are very sweet, ripening in late August. Bartlett begins bearing when still young and will continue to bear fruit for up to 80 years, if well cared-for. This multi-purpose variety of pear tree is self-fertile.
