Cold temperatures can be a limiting factor for fruit trees. Many zone 4 gardeners think apple and pear trees are their only choices because they are generally the hardiest fruit trees. Apples and pears need a certain amount of cold or "chill hours," which refers to a minimum number of consecutive hours in winter when the temperature ranges from 32°F to 45°F.
Luckily, zone 4 gardeners do have delicious options in apple and pear varieties and other fruit tree choices to plant and enjoy.

Bosc is fast-growing and bears fruit that, while not the juiciest, is sweet. Greenish-brown during most of the summer, the fruit turns brown by the time it's harvested late in the season. Bosc trees to dry out. Till the soil deeply before planting, because it likes to strike roots deep into the ground.

The cold-hardiest plum is the beach plum. At only six feet tall, it won't take up much space and is not fussy about soil (in fact, it's salt-tolerant). This tree does require excellent drainage since its native habitat is sand dunes. The small fruits, which are harvested in August, are one inch and dull purple when ripe.

- Mature Size: 6 feet
- Sun Exposure: Full sun
- Soil Needs: Well-drained

Early Richmond Cherry (Prunus cerasus 'Early Richmond')

While you can grow cherries in zone 4, don't expect to grow the sweet Bing cherries (Prunus avium 'Bing') you find at the supermarket (zones 5 to 8). The cherries found in zone 4 are tart cherries suitable for pies and preserves. Early Richmond is self-fertile, but planting multiple trees promotes better pollination. It has some drought tolerance but is intolerant of boggy soils, so it is best grown in well-draining, sandy soil. The fruit usually ripens by mid-summer about a week before other varieties.
- USDA Growing Zones: 4 to 8
- Mature Size: 18 feet
- Sun Exposure: Full sun
- Soil Needs: Well-drained
