Each summer a small tree in our yard produces more delicious cherries than we can harvest and eat.

Tart cherries are outstanding yard trees. They are small, attractive, need little care and begin bearing fruit when only a couple of years old. Trees self-fertile, meaning it’s not necessary to plant two or more for cross pollination. Few insects or diseases bother them but sometimes birds, especially robins, take a fancy to the bright red fruit. Birds prefer mulberries to cherries so we keep a mulberry in the yard as our decoy tree to keep birds from filching cherries.

Commercial nurseries sell two general types of domestic cherry trees-sweet and sour (sometimes called tart or pie cherries). Sweet cherries don’t like subzero winters and are best grown in places warmer than our Iowa yard. The fruit is commonly sold in grocery stores and is delicious fresh. Most varieties need a second tree for cross pollination. In contrast tart cherries don’t seem to mind occasional 25 below zero temperatures and thrive in the north. Rarely sold fresh in stores, tart cherries can usually only be purchased canned. To enjoy delicious fresh tart cherries grow your own.

Two common tart cherry varieties we like are Montmorency and Dwarf North Star. Both produce tasty fruit. Sometimes the fruits are sweet enough to eat right off the tree. But usually their tartness makes them best when used in pies, cobblers, and other baked goods. We like them in our morning oatmeal.

The downside of cherries is the time it takes to pick and pit the small fruits. It can be tedious. Dwarf trees reduce or eliminate the need for ladders, making picking safe, fast and easy. We used to hand pit the fruits using fingers to squeeze the large seed out of each cherry. After a few years of this slow process we bought a cherry pitting device that speeds and eases the process, but it still takes time.

Pitted cherries freeze well. Put a big handful in a plastic freezer bag, squeeze out the air, seal the bag and put it in the freezer to retrieve months later when the urge for cherry pie arises.
