Zone 3 Fruit Trees?

Question:I live in a Zone 3. I am wanting to grow some fruit trees. Which would be my best choices?
For those of you who aren't familiar with planting zones, USDA Zone 3 has minimum temperatures that reach an average of -30 to -40 degrees F (-34.5 to -39.9 C). These conditions are found in the far northern hemisphere and the tip of South America. (for a nice visual representation of Zone 3's distribution, look at zones 4 and 5 on the Aden Earth Map, which labels the zones differently than the USDA does.
Amazingly, there are many fruit trees that will grow in Zone 3, including varieties of cherries, pears, apricots, apples, and plums. The crabapple will grow in Zone 3 (the "Chestnut Crab" variety is supposed to be sweeter than most), as will the chokecherry (Prunus virginiana).
The critical time for setting fruit is during blooming. If the temperature drops below freezing then (usually these plants bloom in mid-summer) the tree will drop its flowers and you won't get any fruit. So it's important to watch the thermometer then.

Let's take a look at some specific varieties for in-ground planting:
Apples: Lodi, Honeycrisp, Goodland, Oriole, Fall Red, Mantet, Red Baron, Early Harvest, State Fair, Beacon, Sweet Sixteen, Haralson, Red Haralson, Fireside, Norkent, and Keepsake.
Pears: Ure (plant the Siberian pear nearby to cross-pollinate for good fruiting), Cabot, Clark
Plums: cherry plum (Prunus cerasifera -- very ornamental, make sure you get a fruiting variety), Black Ice, La Crescent, Superior
Apricots: Manchurian apricot (Prunus armeniaca var. mandshurica, also called the scout apricot. "Adirondack Gold" is supposed to be a sweeter variety)
Cherries: Mesabi, Nanking, Meteor, Evans, Carmine Jewel (this is a dwarf cherry developed by the University of Saskatchewan)
St. Lawrence Nurseries has a LOT of information on their site about growing fruit trees in extremely cold climates, plus information on many more fruit tree varieties you can investigate further.
This article on cold climate fruit trees has good tips on placing your fruit tree as well as other variety suggestions
Another great resource can be found in your local extension office. Usually this is found in association with your county, province, or local major university with an agricultural program. These organizations have a wealth of information as to local conditions, varieties proven to do well in your area, and advice about timing of planting and pest control (if needed).
Of course, you can always plant dwarf trees in containers and bring them inside when the temperature drops below freezing. This way you can plant anything you like!
