Question:I live in a Zone 3. I am wanting to grow some fruit trees. Which would be my best choices?
Answer:
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
