Dolgo Crabapple Tree is a great crabapple variety brought from Siberia in the late 1800’s. Crimson red, 1-1/2″ long fruits follow Dolgo’s profuse, large, snow-white flowers. Use richly flavored Dolgo fruit for cider, preserves and canning. Dolgo is hardy to at least minus 40F. and is very disease resistant and easy to grow.
Latin Name: Malus domestica
Site and Soil: All apples like 1/2 day to full sun and well-drained soil.
Rootstock Description: Considered a semi dwarf rootstock, trees on M-7 typically grow 12-16 ft. in height, and are spaced 12-16 ft. apart. Crabapples, Columnars, Espaliers, and Combination Apples will be smaller. A particularly good apple rootstock for heavy soils, M-7 is hardy to minus 35F. Vigorous and well anchored, trees on M-7 should not require staking.
Pollination Requirements: All 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: Dolgo Crabapple Tree is hardy to at least minus 40 F.
Bearing Age: 2-3 years after planting.
Size at Maturity: 12-16 ft. in height

Pests & Diseases: All apples, except those that are described as disease resistant, can be affected by Apple Scab. Apple Scab is especially a problem 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. Pests such as Codling Moth and aphids can also damage apples or the foliage of apple trees. See our Sulfur and Codling Moth traps in the Supplies section.
