Other Common Name(s):
- Phonetic Spelling
- ULM-us POO-mil-uh
- Description
-
Very adaptable tree, fast-growing and often grows in poor soils and withstands drought. It is resistant to Dutch elm disease has been used to develop other elms with resistance. It is generally is considered a poor ornamental tree, mostly because of its weak branches, messy habit, and susceptibility to insect attack, especially leaf beetles. It can form large colonies with its copious seed formation and is considered invasive in some states. Uses would be in poor soils for erosion control in areas where ornamental value is not a consideration.
Insects, Diseases, and Other Plant Problems: The leaves often eaten by elm leaf beetle. Other problem insects include borers, leaf miners, mealy bugs, caterpillars, and scale. It is resistant but not immune to dutch elm disease and phloem necrosis. It suffers from various wilts, rots, and cankers.
