Pests and diseases

No specific information available, but the species as a whole is highly susceptible to Dutch elm disease and elm yellows; it is also moderately preferred for feeding and reproduction by the adult elm leaf beetle Xanthogaleruca luteola , [3] and highly preferred for feeding by the Japanese beetle Popillia japonica [4] [5] in the United States. U. americana is also the most susceptible of all the elms to verticillium wilt. [6]

Young trees are grown in Belgium and London, cloned from a tree (now dead) which grew in Illinois.
