Another consideration in planting fruit trees is pollination. Most apples, sweet cherries and pears, and some plum, peach, nectarine and apricot trees require planting two different varieties for cross pollination. If you do not have room for two trees, you can find trees with multiple varieties grafted onto the same tree.
Multiple varieties are also commonly available on espalier trees. “Espalier” refers to a special practice for training trees onto trellises. Espalier trees can be trained along a wall or serve as a fence. Another possibility is to plant two trees in the same hole, with a double trunk and branches trained to grow on only one half of each trunk.
The most popular small fruits are strawberries and blueberries. Blueberries are ideal for home gardens in our area. Plants can also serve as landscape shrubs. They are well adapted to our native soil conditions and require a limited amount of attention. Strawberry plants can be used as ground cover. Choose day-neutral strawberries for summer long harvest. Blackberries, raspberries, currants, gooseberries and grapes can be grown in a limited amount of space. Other unusual small fruits include quince, aronia, cranberry, goji berry, goumi berry, honeyberry, lingonberry and serviceberry. The less common fruits are available at online catalogs like raintreenursery.com.
