Fruit trees bear at different times of the year. For example, there are apples for early season, mid-season, and late season (well into fall), so it is wise to select trees for the season you want. Just how long it will be before trees will bear is another consideration; apples and pears bear in 4 to 6 years; plums, cherries, and peaches bear in about 4 years.
Besides considering bearing season and length of bearing, you should also think of size. In addition to standard-sized fruit trees there are dwarf varieties that grow only a few feet. There are also different kinds of apples, peaches, or cherries; your local nursery will tell you about these. Your nursery also stocks the type of trees that do best in your area, so ask for advice. Your trees must be hardy enough to stand the coldest winter and the hottest summer in your vicinity.
Many varieties of fruit trees are self-sterile, which means that they will not set a crop unless other blossoming trees are nearby to furnish pollen. Some fruit trees are self-pollinating or fruiting and need no other tree. When you buy your fruit trees, ask about this. Fruit trees are beautiful just as decoration, but you also want fruits to eat.
