Pear trees are some of the easiest fruit trees to grow in home gardens and orchards. Fairly trouble-free, with few insect and disease problems, pear trees produce fruits that are excellent for fresh eating, desserts and canning. Before buying pear trees for sale online, make sure they will grow in your hardiness zone or grow zone. Next, take into account how tall and wide the tree will be at maturity. Larger than dwarf varieties, standard pear trees usually produce more fruit and require a ladder for pruning and harvesting. Dwarf varieties are usually more manageable and easier to fit into smaller gardens and landscapes. All pear trees perform best when they receive at least six or more hours of direct sunlight daily. Most pear trees require another variety for pollination.
