Pests and diseases

The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.^[2]

Cultivation

Restricted to North America; the only known introduction to Europe, is at the Grange Farm Arboretum, England.

Putative specimen

A notably pendulous small-leaved elm in the JC Raulston Arboretum, Raleigh, North Carolina (2019), labelled Ulmus minor subsp. minor 'Pendula', 'Weeping small-leaved elm', has U. pumila-type fruit and is indistinguishable in leaf and form from U. pumila 'Dwarf Weeper'. The arboretum acquired other specimen trees from Arborvillage Nursery, Holt, Missouri.^[3]
