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
NC State reports no serious disease problems.
Insects to recognize
Spongy moth caterpillars can defoliate trees; identify heavy caterpillar feeding rather than assuming every chewed leaf is harmful.
When to look
Inspect foliage during spring and summer.
A useful first step
Monitor canopy recovery and seek advice for repeated heavy defoliation.
More growing details
Read the leaves
Prominent parallel side veins run to teeth; smaller teeth occur on the larger teeth.
Read the bark
Thin narrow strips loosen from the trunk, unlike hornbeam's smooth muscular bark.
Fruit & seed
Each small nut sits inside a pale inflated papery sac, clustered like hops.
Winter character
Fine shredding bark plus lingering hop-like fruits offer useful winter clues.
Origin & place
The species occurs naturally in the southern Appalachian region; a planted specimen is not evidence of wild local origin.

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.
