Manchurian Ash

‘Mancana’ is a compact selection of Manchurian ash, a deciduous shade tree with a dense crown and strong branches. Its rounded outline becomes broadly oval as it matures, while bright green summer foliage turns vivid yellow in fall. ## Landscape Use The [University of Minnesota UFOR Nursery & Lab](https://trees.umn.edu/nursery-tour/species/maas) lists mature dimensions of 40–50 feet tall by 25–30 feet wide and describes the cultivar for yards, parking strips, and places where a broad canopy is useful. Keep the mature spread clear of buildings, overhead lines, and narrow walks. ## Foliage and Seasonal Interest Compound leaves provide a green canopy through the growing season and a strong yellow display before dropping. The UFOR profile describes the cultivar as seedless, with stout branches that stand up to heavy snow and ice. Manchurian ash flowers in spring before its leaves emerge, as noted in the [UMN species profile](https://trees.umn.edu/manchurian-ash-fraxinus-mandshurica). ## Growing Conditions The exact-selection source gives USDA zones 2–6 and describes tolerance of a range of soils. Full sun, good soil, and adequate water support the fast growth reported by UFOR. Water deeply while the tree establishes and check moisture during extended dry periods. ## Maintenance Allow room for the developing crown and maintain a clear central structure with selective pruning when young. Remove broken or crossing branches as needed, and avoid topping that would spoil the natural oval form.
