Wolf River Apple Tree
Named for the river in Wisconsin where it was discovered, Wolf River is notable for its exceptionally large fruits which often weigh in at over a pound! The tree is exceptionally cold hardy and disease resistant. Fruit can be eaten fresh but its primary use is for cooking, as it holds its shape very well, and is also an excellent winter keeper.

Latin Name: Malus pumila
Site and Soil: Apples like 1/2 day to full sun and well-drained soil.
M-7 is considered a semi-dwarf rootstock growing 12-16 ft. in height. M-7 is very hardy and adapted to most soils. Vigorous, drought tolerant, and well anchored, trees on M-7 should not require staking.
M-26 is considered a dwarf rootstock, growing 8-12 ft. in height. M-26 induces early bearing, usually in 2-3 years after planting, and grows well in most soils, except very wet and poorly drained ones. On windy sites, trees grafted on M-26 may need staking.
Pollination Requirements: Apples need another variety nearby for pollination. Neighboring trees often offer sufficient pollen for good fruit set. Consider Mason Bees to help pollinate and increase fruit production.
Hardiness: Hardy to minus 30° F or below.
Bearing Age: 2-3 years after planting
Size at Maturity: Dwarf 8-12ft. / Semi-dwarf 12-16 ft.
Fruit Skin: Red
Fruit Flesh: White
Bloom Time: April
Ripening Time: Early August
Yield: 30-50 lbs.
Pests & Diseases: Wolf River can be affected by Apple Scab although it is considered resistant. Apple Scab is more prevalent in regions with wet springs, like we have in the Pacific Northwest. While it doesn’t seriously affect the eating quality of the fruit, it can cause black spots on the apples and foliage. Apple Scab can be controlled by sulfur and other sprays. Codling Moth can create wormy apples and aphids can damage the foliage of apple trees.
USDA Zone: 4-8
