Uses
This tree is occasionally cultivated as an ornamental tree in parts of Canada and the United States. Manchurian Ash can be used as a medium height wind break for a farmstead. It is also highly tolerant of urban pollution and will even grow well in inner city environments. The tree also makes an excellent landscape tree in moist areas, especially along roads and ditches where a good amount of water can be available. The Manchurian grows into a denser oval form with age.
It has proved very intolerant of oceanic climate conditions in cultivation, leafing out too early and then being damaged by late spring frosts.
The species is being tested as a potential source of genes for resistance to emerald ash borer Agrilus planipennis, an Asian insect which occurs alongside Manchurian Ash in the wild, and which has become an invasive pest species in North America. However, significant mortality in Manchurian Ash from emerald ash borer is also recorded in the wild in China.
The cultivar Fraxinus mandschurica 'Mancana' ("Manchana Ash") has been selected by the Morden Research Station, Morden, Manitoba. It has a dense oval to globose crown, and is a male tree; it is very hardy. Hybrids with Black Ash have also been produced in cultivation.
