Because they are fairly trouble-free, with few insect and disease problems, pear trees are a favorite for growing in the home garden or landscape. The fruits are excellent for fresh eating, desserts and canning. When selecting pear trees to buy, make sure the pear tree variety is suitable for your grow zone or hardiness zone. Next, take into account the pear tree's space requirements. Both standard and dwarf pear trees are available, and dwarf pear trees are often a good solution for gardeners with limited space. All pear trees grow best and produce the most fruit when planted in full sun, or six or more hours of direct sunlight daily. Most pear trees require another variety for pollination.
