Problems to recognize in WNC gardens. These are documented susceptibilities, not a local outbreak report or a diagnosis. Weather, elevation and growing conditions change the risk.
Diseases & similar-looking injury
Generally resistant to Dutch elm disease; occasional cankers, wilts and leaf spots can still occur.
Insects to recognize
No major insect problem is emphasized in the NC State profile.
When to look
Check canopy condition through spring and summer.
A useful first step
Investigate repeated wilt and dieback; resistance to one disease does not explain every declining branch.
More growing details
Read the leaves
Look for a subtly unequal leaf base and sharp marginal teeth. Trace alternate attachment on the twig; the imbalance at the base is often less obvious than on American elm.
Read the bark
Mature bark sheds patches to reveal tan, orange, gray, and greenish areas.
Fruit & seed
Small papery winged samaras develop in fall, contrasting with spring-fruiting American elm.
Winter character
Patchwork bark and fine alternate twigs remain useful.
Origin & place
An introduced garden species or horticultural hybrid; study it as part of WNC landscapes rather than assume it belongs to the native mountain flora.
WNC Notes

LOOK CLOSELY
Two views, a closer look.
Place two photographs beside one another. Compare the overall plant with leaves, flowers, or bark when those views are available. Captions identify what each photograph actually shows. Images are not at the same scale; species references may show different cultivars.
